But partner to that and encompassing the mass of the iceberg that the conscious mind is the tip of lies the vast and rather mysterious world of the human unconscious mind.\n\nThe Achilles Heel of Your Cognition\nThe unconscious realm of the human mind is where mental processes, thoughts, and information operate beyond the reach of our conscious awareness. It is a hidden domain so to speak to many. In its workings, it handles incredibly important and diverse substantial portions of our cognitive activities. It is thoroughly involved in influencing our decisions, behaviors, and emotional responses. It is in this manner an area of great interest to governments, the military, the media, big technology companies, big pharma, and a host of industries that use it to control our responses to certain stimuli or our reactions to certain events or emerging patterns that are introduced into our societies and our daily personal lives and loves.\n\nActive not Passive\nThe unconscious human mind is not passive. It is continually processing information, making connections, and affecting our perceptions without us even realizing it. It stores implicit memories, those bits of information from our past that shape our preferences and reactions, often without conscious recall.\n\nHabitual Auto-Responses\nDo you ever wonder why certain habits seem to run on autopilot? That's the unconscious mind at work, turning conscious actions into ingrained routines, allowing us to navigate our daily lives more efficiently.\n\nEmotional Powerhouse\nThe unconscious mind is not just about habits and memories; it plays a crucial role in processing emotions. It can stir up feelings and responses based on past experiences or associations, and these emotional undercurrents often drive our decisions and actions.\n\nSleep and Dreams\nDuring sleep, the unconscious mind comes alive in our dreams, which can offer insights into our inner thoughts and emotions. Dreams can be a window into the subconscious, revealing aspects of ourselves that we may not readily acknowledge in our waking state.\n\nDefensive Cognitive Moat\nThe unconscious mind can also employ defense mechanisms to shield us from distressing thoughts or emotions, a process seen in psychological theories like repression or denial.\n\nWhat is in this Lecture?\nIn this Lecture, we will explore the various facets of the unconscious mind, its impact on our daily lives, and how understanding it can lead to greater self-awareness and personal growth. This Lecture allows the student to gain a deeper appreciation of the complexities of our unconscious state and the factors external to ourselves that can be employed to influence it, for good and for ill, over time.\nWATCH ON X: https://t.co/ahBiW1dId6\nWATCH ON YOUTUBE: https://t.co/EvrGaJH7sU\n\nIf you have any questions on the course material content then please post them in the comments on the YOUTUBE CHANNEL and NOT on X.

Along the way, they have become remarkably good at reading our gestures and picking up on our cues.\n\nNow researchers think dogs might also help answer a much bigger question: how did humans become the only species capable of spoken language?\n\nDr Tamás Faragó, a bioacoustics researcher at Eötvös Loránd University in Budapest, has spent nearly two decades studying how dogs communicate through sound. Through K9VocLearn, a five-year research project backed by EU funding, he and his team are now considering whether domestication changed the way dogs use their voices – and what that might reveal about the evolution of human speech.\n\nWhy dogs?\n\nThe researchers are investigating whether thousands of years of living alongside humans gave dogs some of the building blocks of vocal learning – the ability to modify vocalisations by listening to others.\n\n“Vocal learning is a unique ability in humans, and it is a very strong prerequisite for spoken language,” said Faragó. “Without the ability to modify your vocalisations and learn new vocalisations to produce new sounds, you cannot really learn how to speak.”\n\nHumans take this ability extraordinarily far, learning and deliberately producing the huge range of sounds needed for spoken language. Only a small number of other mammals show anything similar. Dolphins, whales, seals, bats and elephants can imitate or modify sounds to varying degrees, while great apes – our closest relatives – show much more limited vocal flexibility.\n\nDogs occupy a unique place in evolution – bred over thousands of years for particular traits that made them useful to humans.\n\n“During domestication, dogs were selected for tameness, being socially tolerant with humans, and for being able to cooperate with humans for hunting, herding, livestock driving,” Faragó said.\n\nDomestic cooperation\n\nThe researchers are exploring whether the same traits that made dogs increasingly cooperative and socially tolerant may also have affected their ability to control and alter the sounds they make.\n\n“Dogs have a lot of social cognitive abilities very similar to humans and our ability to cooperate. That’s why we thought dogs might be a very good model for these early human evolutionary steps,” said Faragó.\n\nThis connects to an intriguing – but still debated – idea in evolutionary biology known as the self-domestication hypothesis. It proposes that, over the course of human evolution, selection favoured greater social tolerance and cooperation, producing some changes comparable to those seen when animals were domesticated.\n\nIf greater social tolerance also favours more flexible communication, studying what domestication did to dogs could offer clues to some of the evolutionary conditions that eventually helped make human speech possible.\n\nOne clue lies in how much dogs’ voices have changed from those of their wild ancestors. A 2023 study found that breeds genetically closer to wolves were more likely to respond to a howl by howling, while breeds more distantly related to wolves were more likely to bark.\n\nUnlike wolves, dogs bark in almost any situation. Researchers Eötvös Loránd University believe this is a direct product of domestication, possibly because early humans favoured dogs that could raise the alarm vocally.\n\nThat shift, from a rare wolf behaviour to a constant, human-directed signal, is exactly what K9VocLearn is trying to explain.\n\nInside the lab\n\nAt the aptly named Budapest BARKS Lab (Behaviour and Acoustics Research for K9 Sounds), the researchers are building the most detailed picture yet of canine vocal communication.\n\nDogs are presented with situations designed to evoke a range of emotions. They play games, tackle simple learning tasks, experience brief separations from their owners and even come face-to-face with an inflated bin bag that “mysteriously” moves across the room.\n\nEvery bark, whine, growl and howl is recorded alongside behaviour and heart rate, helping researchers connect particular vocalisations with emotional states.\n\nThe next question is whether dogs can learn to produce some of these sounds voluntarily. The training sessions are designed by Dr Sára Sándor, a geneticist and qualified dog trainer.\n\n“Currently we are running pilot trainings to develop our protocol,” she said, stressing that the researchers are focused on figuring out how to train dogs to vocalise and participate voluntarily. “You don’t want to put any pressure on the dogs. You don’t want to force them to do anything.”\n\nCentral to the approach is letting dogs choose whether to continue.\n\n“We teach the dogs how to give consent, so if the dog feels the situation is stressful, or it feels tired, it can signal that it doesn’t want to continue. Vocal learning is tiring for dogs, so we need to keep sessions short and give them as much control as possible.”\n\nSound control\n\nThe goal is not to teach dogs to “talk” in the human sense, but to discover how much voluntary control they have over their own sounds. Rather than reading too much into a dog’s behaviour, Faragó’s team tests something more specific. Can a dog learn to produce, on cue, a whine it would normally make from excitement – without the ball that usually triggers it?\n\nIt is not just highly vocal dogs that take part.\n\n“Everything is data for us, so we are also interested in the trainability of dogs with minimal vocal repertoires. We currently have one barely vocalising dog who nevertheless got the idea in one session and now it loves woofing on cue,” Sándor said.\n\nBeing naturally “chatty” does not necessarily make a dog better at controlling its voice. Talkative dogs may bark because of genetics, their emotional state or an external trigger, rather than because they can deliberately choose to produce a particular sound. True vocal control works both ways: it can also mean learning to stay quiet when asked.\n\nThe team has so far relied on its own family dogs, but will soon recruit a much bigger cast of volunteers. Owners across Budapest will follow training protocols at home before bringing their pets to the BARKS Lab to yap, whine and howl in the name of science.\n\nThe work will also reach out beyond the lab. Through a citizen science challenge, inspired by the earlier Do As I Do Woof Challenge, dog owners worldwide will be invited to submit recordings a lab could never capture: contented sighs, sleepy snuffles, the quiet sounds a dog makes settling in for the night.\n\nOwners will also be able to contribute DNA samples and behavioural surveys, helping researchers hunt for genes that might explain why some dogs have greater control over their vocalisations than others.\n\nWhat it means for us\n\nBeyond the origins of speech, the research could bring practical benefits.\n\n“One of the possible applications is developing smart devices which can detect the emotions of dogs based on their vocalisations,” said Sándor.\n\nAI is already being explored as a way to identify information about a dog’s emotional state from its vocalisations. A better scientific understanding of canine vocal communication could help owners recognise fear, stress or frustration before behavioural problems escalate, improving welfare and strengthening the relationship between people and their pets.\n\nBut the bigger question goes much further back.\n\nDogs have spent thousands of years evolving alongside humans, adapting to many of the same social pressures for cooperation and tolerance that some researchers believe also helped pave the way for human language.\n\nIf domestication gave dogs a flexible new voice, they may be quietly holding one of the missing pieces in the story of how humans learned to speak.\n\nhttps://t.co/p4bLeP6jsx","author":"Twitter for iPhone","url":"https://zmescience.com/ecology/animals-ecology/this-scientist-is-teaching-dogs-to-control-their-barks-to-learn-how-human-speech-evolved","video_id":null,"domain":"Biology","depth":"Intermediate","duration_seconds":null,"source":"twitterapimcp","source_url":"https://x.com/i/status/2096573117682348235","discovered_at":"2026-09-12T07:10:17.428Z","published_at":"Sun Sep 06 12:15:58 +0000 2026","topic":"biology genetics research explained","transcript":[],"chapters":[],"score":1,"quality_reasons":["Educational format","Substantive source description","Subject relevance","Accessible talk format","Widely loved or iconic","Approachable level"],"title_en":"This Scientist Is Teaching Dogs to Control Their Barks to Learn How Human Speech Evolved | Alison Jones, ZME Science","description_en":"This Scientist Is Teaching Dogs to Control Their Barks to Learn How Human Speech Evolved | Alison Jones, ZME Science\n\nFor over 14 000 years, dogs have hunted with us, guarded livestock, herded sheep and, more recently, curled up beside us on the sofa.

Washington / HHMI) Part 1: Introduction to Protein Design","description":"http://www.ibiology.org/ibioseminars/david-baker-part-1.html\n\nLecture Overview:\n Baker begins his talk by describing two reciprocal research problems. The first is how to predict the 3 dimensional structure of a protein from a specific amino acid sequence, while the second is how to determine the amino acid sequence that will generate a new protein designed to have a specific structure.  Baker’s lab is addressing the second of these challenges by developing computer programs (such as Rosetta@Home) that calculate the lowest energy, or most likely, structures for differently folded amino acid sequences.  Baker explains how his lab can design a new protein structure, not found in nature, and using the computer programs they have developed, determine the amino acid structure. It is then possible to back translate to the DNA sequence and synthesize the gene that can then by used to make the protein.  When the structures of these synthesized proteins are determined by crystallography and compared to the predicted structures of the designed proteins, they are found to overlap very closely demonstrating that the protein design algorithms work well. \n In the second of his talks, Baker tells us how his lab has moved beyond designing new protein structures to designing new protein functions.  The first example he describes is the development of an inhibitor of the influenza virus.  Baker’s lab designed a protein structure that fits into a highly conserved region of the hemagglutinin protein found on the surface of influenza.  Preliminary lab data suggests that this designed protein protects mice from infection with the flu virus.  Baker also describes experiments in which proteins were designed to fit together and build multicomponent materials such as nanocages, nanolayers and nanowires.\n\nSpeaker Bio:\nDavid Baker received a BA in Biology from Harvard University and a PhD in Biochemistry from the University of California, Berkeley.  Currently, Baker is the Head of the Institute for Protein Design and a Professor of Biochemistry at the University of Washington, and a Howard Hughes Medical Institute Investigator. His research utilizes both experimental and computational methods to study the design of protein structures, and the mechanisms of protein folding, protein-protein and protein-small molecule interactions. \nBaker’s lab developed the crowd-sourced protein folding design programs Rosetta@home and Foldit.  Learn more about these programs in Baker’s iBioMagazine talk and at his lab webpage http://www.bakerlab.org/static/ .  \nBaker has won numerous awards for his work including the Raymond and Beverly Sackler International Prize in Biophysics in 2008.  Baker is a member of the National Academy of Sciences and the American Academy of Sciences.","author":"Science Communication Lab","url":"https://www.youtube.com/watch?v=0LetJMbu7uY","video_id":"0LetJMbu7uY","domain":"Biology","depth":"Intro","duration_seconds":1282,"source":"serperdevmcp","source_url":"https://www.youtube.com/watch?v=0LetJMbu7uY","discovered_at":"2026-09-13T00:00:40.736Z","published_at":"Nov 25, 2014","topic":"molecular biology protein folding lecture","transcript":[],"chapters":[{"at":0,"title":"Intro"},{"at":38,"title":"Native structures are likely global energy minima"},{"at":68,"title":"TWO RESEARCH PROBLEMS"},{"at":495,"title":"Classes of proteins found in Nature: Globular proteins"},{"at":627,"title":"Protein Design Work Flow"},{"at":736,"title":"Design of ideal globular protein structures"},{"at":953,"title":"Assembly of complex protein topologies by fusion of designed ideal structures"},{"at":988,"title":"Design of ultrastable helical bundles based on Francis Crick equations"},{"at":1091,"title":"Design of new repeat proteins Design self-complementary 2-helix repeating unit using Rosetta with repeat symmetry"},{"at":1145,"title":"Design of cyclic peptides with stable backbone conformations"}],"score":1,"quality_reasons":["Educational format","Substantive source description","Subject relevance","Accessible talk format","Approachable level","Short and easy to start"],"author_url":"https://www.youtube.com/@scicommlab","thumbnail":"https://i.ytimg.com/vi/0LetJMbu7uY/hqdefault.jpg","channel_id":"UCsvqEZBO-kNmwuDBbKbfL6A","comments":[{"id":"Ugzpw-fEpc1Twky33y94AaABAg","author":"@scicommlab","text":"Congrats to David Baker who just won the #nobelprize2024 \"for computational protein design\" with Demis Hassabis and John M.

Ashna has spoken on what is topology, different branches of topology, and the immense opportunity that lies ahead in making a career in topology.\n\nSubscribe for more physics and mathematics videos: \nhttps://www.youtube.com/physicsforstudents?sub_confirmation=1\n\nJoin this channel to get access to perks:\nhttps://www.youtube.com/channel/UCVDb3R8XY1FIEIccTT1NnpA/join\n\n\n(1) Channel: https://www.youtube.com/physicsforstu...\n(2) General Relativity:https://www.youtube.com/@generalrelativityexplained\n(3) Facebook: https://www.facebook.com/physicsforst...\n(4) Instagram: https://instagram.com/physics_forstud...\n(5) Linkedin:https://www.linkedin.com/in/physicsfo...\n\nEmail: contact.physicsforstudents@gmail.com\nContact: +91 9830219677\n\nThe objective of this channel is to provide educative videos on physics and mathematics.\n\nPlaylists:\n\n(1) Most watched videos\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LASW2OMOXhtqYLhrAOY8GgJ\n\n(2) Quantum Mechanics\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LCvulxRDc8mBeadEv1mGlnx\n\n(3) Special Relativity\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LDlFXMz2Kd92ElkCyYERPlo\n\n(4) General Relativity\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LAVDW8FGXhBgQDbYrcKXXey\n\n(5) Black Holes\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LD9V1md0JQMwkU6SH0tbEKa\n\n(6) Differential Geometry\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LCapNhpUYAZqUu3xfgHZ76w\n\n(7) Topology\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LBhbTtDfxK9P9VoSuTTd6If\n\n(8) Vectors and Tensors\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LCHM3SzJgCmmPHVaNFE5D0s\n\n(9) Real Analysis\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LA2IhQincXlr-qwjo7svOgX\n\n(10) Maxwell's Equations\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LDVJ3QTTE9YrC984iuwc7tX\n\n(11) Classical Physics\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LBcZzSzlpOFmuNQLoR535wj\n\n(12) Basic Mathematics\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LC-1Gn4HpcOQaubEmr-QaBY\n\n(13) Calculus\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LC5fHDWK6i2AJjpajwU98Nd\n\n(14) Concept Building \nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LDgFseXD2K_bX21tDYo4Zp5\n\n(15) How To Learn Mathematics\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LDYh7lVy-WwjEt0IVC2jJJg\n\n(16) Tagore Einstein conversations\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LBBQLMb3FMr4oKYbFeQFZwR\n\n(17) Biographies\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LCTyHei0dqlRt2uTsBNdD5t\n\n(18) Grigori Perelman\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LDWKF2fSL-DtOudD3QcnUoR\n\n(19) String Theory\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LDvBMwyb45MI7OJPg7yEGy2\n\n(20) Shorts\nhttps://www.youtube.com/playlist?list=PL2n-gxsZ_8LCUIr5FGDC_40Q08Og6cGaI\n\nMy name is Shounak.

In 2010, Dana Carney, Amy Cuddy, and Andy Yap published a paper in Psychological Science reporting that 42 participants who held expansive “high power” poses for one minute showed increased testosterone, decreased cortisol, and greater self-reported feelings of power and risk tolerance compared with participants who held a contractive “low power” pose. The finding, popularized in a TED talk that became one of the platform’s most viewed, was framed as evidence that body language does not just reflect how powerful you feel, it can produce the feeling and the underlying biology.\n\nThis is one study, not settled consensus, and in the years since publication, its central claims have mostly not survived closer scrutiny.\n\nWhat happened when other researchers tried to replicate it\n\nIn 2015, Eva Ranehill and colleagues published a replication in Psychological Science using a considerably larger sample, 200 participants compared with the original 42. They found no measurable effect of power posing on testosterone, cortisol, or actual risk-taking behavior in a financial task. The one part of the original finding that did replicate was subjective: participants who held expansive poses reported feeling more powerful afterward, even though no hormonal or behavioral change accompanied that feeling.\n\nThe response from the original research team was notable in itself. In 2016, Dana Carney, one of the original study’s own co-authors, published a public statement saying she no longer believed the power-posing effect was real, citing concerns about the small sample size and the statistical practices used in the original 2010 paper. A subsequent replication effort has since reported a more mixed picture, finding no effect on testosterone or self-reported feelings of power, but partial support for effects on cortisol and risk-taking, which illustrates how unsettled this specific question remains rather than resolving it cleanly in either direction.\n\nFeeling powerful and appearing powerful are different questions\n\nThe power-posing story is specifically about what a pose does to the person holding it. A separate, older body of research asks a related but distinct question: what postures and behaviors make a person appear powerful to other people watching them. Here the evidence is less dramatic but considerably more consistent.\n\nDana Carney, along with Judith Hall and Lavonia LeBeau, published a 2005 paper in the Journal of Nonverbal Behavior examining beliefs and evidence around seventy specific nonverbal behaviors associated with social power, defined both as a personality trait and as an organizational role. The researchers found real, measurable differences across roughly half of the behaviors studied, including posture, gesture, and vocal patterns associated with higher-power roles and traits.\n\nThe study distinguished power as a stable personality trait, a general tendency toward dominance across situations, from power as a role, the rank a person actually holds within an organization at a given moment. That distinction is worth keeping in mind, because a nonverbal cue that reliably tracks with someone’s assigned rank in a workplace is not automatically the same cue that reflects a person’s underlying dominant disposition, and the paper found the two did not always overlap in the same behaviors.\n\nWhy the perception often outruns the reality\n\nA related meta-analysis, by Judith Hall, Erik Coats, and Lavonia LeBeau, examined a wide range of nonverbal behaviors, including facial expression, eye gaze, interpersonal distance, body movement, and touch, in relation to actual and perceived social status. The result worth sitting with: people’s beliefs about which nonverbal cues signal power were stronger and more consistent than the actual differences in behavior between higher-power and lower-power people. In plain terms, most people share a fairly accurate mental model of what powerful body language looks like: more space taken up, steadier gaze, slower and less fidgety movement. But the degree to which genuinely powerful people actually display these cues, measured directly rather than assumed, was smaller and less reliable than the shared belief about it.\n\nThat gap matters for how to read advice about powerful body language. The specific cues most consistently associated with perceived power in this research, expansiveness, stillness, direct and steady eye contact, sound almost identical to the ones featured in popular power-posing advice. The difference is what they are being claimed to do. As a signal that shifts how an observer reads you in the moment, this research gives real support. As a mechanism that changes your own hormones or risk tolerance before you walk into the room, the evidence has largely not held up under closer testing.\n\nWhat this actually supports\n\nTaken together, the honest version of this research points to a narrower and more useful claim than the version that went viral. Adopting an expansive stance before a stressful moment does appear to reliably change how a person feels in the moment, according to both the original study and its replication. What it does not appear to reliably do, based on the larger replication and the original co-author’s own reassessment, is change measurable hormones or actual risk-taking behavior. Separately, and on firmer ground, decades of research into how observers read nonverbal cues suggests that expansive, stable, unhurried body language genuinely does shape how powerful a person appears to others, even though the underlying biological story about why is not the one the original 2010 study told.\n\nWhat this does not prove\n\nNone of the studies discussed here followed people into real negotiations, job interviews, or long-term career outcomes to measure whether appearing powerful through posture actually changes real-world results. The nonverbal-perception research is also decades old in places, drawn largely from lab settings and coded video rather than lived professional interactions, and the specific behaviors that read as powerful may vary somewhat by culture and context in ways this research was not designed to test. The result is a finding from this specific body of work, not a universal rule about every person in every room: body language shapes how you are perceived with real consistency, but the idea that it also rewires your own physiology before you arrive is a claim that mostly did not survive its own replication.\n\nhttps://t.co/q6Bb76sOtS","author":"Twitter for iPhone","url":"https://scienceblog.com/g-body-language-that-makes-a-person-seem-powerful","video_id":null,"domain":"Interdisciplinary","depth":"Intermediate","duration_seconds":null,"source":"twitterapimcp","source_url":"https://x.com/i/status/2083883043782013355","discovered_at":"2026-09-17T00:09:46.330Z","published_at":"Sun Aug 02 11:50:08 +0000 2026","topic":"ted talk 2015","transcript":[],"chapters":[],"score":1,"quality_reasons":["Educational format","Substantive source description","Subject relevance","Accessible talk format","Widely loved or iconic"],"title_en":"The viral 2010 power posing study claimed two minutes of an expansive stance changes testosterone and cortisol, but a 2015 replication with five times as many participants found no such hormonal effect at all | ScienceBlog","description_en":"The viral 2010 power posing study claimed two minutes of an expansive stance changes testosterone and cortisol, but a 2015 replication with five times as many participants found no such hormonal effect at all | ScienceBlog","lang":"en","translated_at":"2026-09-17T00:09:53.605Z"},{"id":"781f205fb177c0c21f34","title":"Video: Steve Jobs Stanford Univ Commencement Address http://bit.ly/R0mPp @tonyrobbins Moving Speaker Lecture Live each day as your last!","description":"Video: Steve Jobs Stanford Univ Commencement Address http://bit.ly/R0mPp @tonyrobbins Moving Speaker Lecture Live each day as your last!","author":"Twitter for iPhone","url":"http://bit.ly/R0mPp","video_id":null,"domain":"Interdisciplinary","depth":"Intermediate","duration_seconds":null,"source":"twitterapimcp","source_url":"https://x.com/i/status/7924134459","discovered_at":"2026-09-16T23:25:42.155Z","published_at":"Tue Jan 19 00:03:44 +0000 2010","topic":"steve jobs stanford commencement address","transcript":[],"chapters":[],"score":1,"quality_reasons":["Educational format","Substantive source description","Established academic source","Accessible talk format","Widely loved or iconic"]},{"id":"2f6ca5412441e9e88a7e","title":"Andrew Ng built the AI team at Google.

Then left and built the AI team at Baidu. Two of the biggest tech companies on earth - he ran the AI strategy for both.\n\nThen he walked into a Stanford classroom and gave this lecture for free.\n\n800 students showed up to a room that seats 300. People sat in the hallways. People watched from outside. This was 2018 - before ChatGPT, before the AI gold rush, before every company on earth was desperately trying to hire people who understood this stuff.\n\nNg saw it coming. He said it in the first five minutes.\n\n\"Today is the same moment the Internet was in 2000. Every person who bet on it early built a fantastic career. That window is open right now for machine learning.\"\n\nThe engineers who finished this course now make $400k at Google. $500k at Two Sigma. $600k+ at hedge funds running quantitative ML strategies. Not because they're geniuses. Because they understand the foundations that Ng teaches here, that almost nobody bothers to learn properly.\n\nTech companies started posting job ads that said: \"If you completed CS229, you get an interview. Guaranteed.\" Not \"it helps.\" Not \"it's preferred.\" Guaranteed.\n\nThis is Lecture 1 of Stanford CS229 - the most influential machine learning course ever recorded.\n\nHere's what actually happens in this lecture:\n\nNg breaks down the entire map of machine learning in plain English. No equations yet. Just the clearest explanation you'll find anywhere of how supervised learning, unsupervised learning, reinforcement learning, and deep learning connect to each other - and why each one matters.\n\nHe shows you a self-driving car demo from the 1990s. A neural network learning to steer by watching a human drive. 1990s hardware. Grainy video. And it works.\n\nSame idea as Tesla Autopilot. Built 30 years earlier.\n\nHe explains why Arthur Samuel's checkers program from the 1950s - the one that beat its own creator at the game - contains the exact same core insight as every large language model running today.\n\nWatch the moment:\n\nAround 37 minutes in, Ng says something most professors would never admit out loud: the gap between a team that wastes six months going in the wrong direction and a team that solves the same problem in three weeks is not talent. It's systematic thinking. He built that system at Google. Then rebuilt it at Baidu. Then put the whole playbook into a free YouTube lecture.\n\nAfter this course, Ng founded Coursera - valued at over $4 billion - and https://t.co/x9hTRzNKiQ, which has trained millions of engineers worldwide. He charges corporations hundreds of thousands of dollars to consult.\n\nHe gave this lecture away.\n\nStanford CS229, Lecture 1. Andrew Ng. Autumn 2018.

And two smears is too much.\nP.S.On the Discrete Gravity (DG)\nEinstein. Relativistic theory of the non-symmetric field (General Remarks, D). The Meaning of Relativity. Fifth edition. Princeton, 1955.\n“One can give reasons why reality cannot at all be represented by a continuous field. From the quantum phenomena it appears to follow with certainty that a finite system of finite energy can be completely described by a finite set of numbers (quantum numbers). This does not seem to be in accordance with a continuum theory, and must lead to an attempt to find a purely algebraic theory for the description of reality. But nobody knows how to obtain in basis of such a theory.”\n0.To discrete expression for the gravitational potential:\"...Containing all information about the gravitational field.\" (Einstein), you can come according to the classics (G), SR  © and De Broglie's hypothesis (h).\n1.Without GR and QM: using ordinary algebra.\na. Kepler's third law: Gm=(r^3)w^2.\n b. The researcher will notice that electrodynamics has achieved great success, compared with mechanics, thanks to the introduction of the concept of current, and will write down Kepler's law as follows: I(G)= mw=v^3/G, where I(G) is the gravitational current: I(G)=[g•sec-1]. {Maxwell's realization of the displacement current effect is the culmination of all (mechanics+electrodynamics) classical physics: \nPauli, RT, Chapter V, §63: “We see, therefore, that the Maxwell-Lorentz electrodynamics, so long as it is not supplemented by an essentially extraneous theoretical element, is generally incompatible with the existence of charges.”; \nBorn, RT, Chapter V, §5: “For Faraday the charges play a quite subordinate part, as the place at which the lines of force start out or end.”}\nc.By the way, in SR: I(G)=inv; this follows from the Lorentz transformations: m=m(0)/√(1-v^2/c^2) and ∆t=∆t(0)/√(1-v^2/c^2). Hence, obviously, we have I(G)=m/t=m(0)/t(0)=inv.\nd. In GR: comparing with Einstein's equations of 1915, we find a=-c^3/16πG. \nStrictly speaking, in order to determine the constant a, it was necessary to make a transition to the Poisson equation. \nThus, a rigorous derivation of Einstein's equations can be given. \nThe transition to the non-relativistic limit allows us to determine a constant factor for the integral of the gravitational field according to: R[(0)^0]=(4πG/c^2)p; Δφ=-pc^3/4a=4πGр.\nAnd a=-(1/16π)m(pl)w(pl).\nThus, I(pl)=m(pl)w(pl)=-16πa ~ the “dark” inv: l(pl)=8πM(Universe)H.\ne. The researcher will get acquainted with the semiclassical Bohr theory, where the quantization rule of the angular momentum: the moment modulus in a stationary orbit is determined by the formula mvr=n’ħ (n’=1,2,3,..). As well as with the de Broglie hypothesis: a free particle should be compared with a plane monochromatic wave, and the wave parameters are frequency and length waves are associated with mechanical characteristics - momentum and energy: k=p/ħ=w/c. And, based on Kepler's law, will write down Newton's law as follows: F=mg=m|a|=(m/t)v= v^4/G=(ħ/c)w^2.\nf.The researcher will remember Einstein's time dilation and the equivalence principle [see Pauli, RT, \"Simple consequences of the equivalence principle\", where v^2=(rw)^2=-2Ф(centrifugal)~-2Ф(G)], and finally writes the quantum expression (as vibration field) for the Newtonian gravitational potential: \nФ(G)=(-1/2)[Għ/c]^½(w) \n{= -[h/4πm(pl)]w=-(½)[w/w(pl)]c^2}.\ng.Real gravitational fields are variable in space and time, and we can now talk about the fact that it is possible to generate a gravitational field in a variable non-inertial frame of reference.\nThat is, finally achieve global (instead of local in GR) compliance with the strong equivalence principle.\nh.And the gravitational field, or more precisely the grav-inertial field is characterized by a spontaneous flow: J(Gi) = (v'/π )(1/4π) g^2/G, where  v'/π- phase velocity of field (space-time) evolution: v’=r(pl)w.\n{Frame of reference in GR: \n\"In the general case of an arbitrary variable gravitational field, the metric of space is not only non-euclidean but also changed with time. This means that the relationships between different geometric distances change over time. As a result, the relative position of the \"test particles\" introduced into the field in any coordinate system can not remain unchanged.\" ( Landau-Lifshitz, II).}\nFor clarity, this phenomenon can be compared to the process when a pioneer train from the initial state rhythmically lays tracks for its step-by-step movement.\nEntropy:S=πε(pl)r(t)=(n+n')k, where k is the Boltzmann constant; n=const for all orbits.Obviously, on the horizon entropy=min. \nP.P.S.

This conjecture initiated by Ray Chiao is based on the dimensional analysis that the electron spin gyromagnetic ratio (e/2m) squared has the same dimension (mass density)^-1 (frequency)^2 as Newton's G in esu units. This implies a Planck area 42 powers of 10 larger than the Newtonian 10^-66 cm^2. We also use Lenny Susskind's ER = EPR world hologram conjecture combined with Hawking's entropy-area equation in this research program's early stages. The main part of this paper deals with an earlier program based on Ray Chiao's 2002 paper on the extended equivalence principle and the Kramer's-Kronig retarded causality dispersion relations proving that Einstein's gravity field equation Guv = KTuv inside matter with electromagnetic dispersion requires an additional frequency-dependent factor Kg called \"gravitational permeativity\" by Chiao so that Guv = KKgTuv. This agrees with my independent work of 2011 presented as an invited talk at the DARPA-NASA 100-Year Starship Meeting in Orlando, Florida where my S corresponds to Chiao's Kg. In addition I have S = (erur)^2 where er is the relative electric permittivity and ur is the relative magnetic permeability in the simplest case of istropic dispersive matter. Micheal G. Anderson of Lawrence Livermore Lab DOE has proposed an S = 10^32 Warp Reactor experiment as a test. In addition, this paper proposed a much easier ice er = 99 to water er = 80 Cavendish experiment in which Active Gravity Mass = S^1/2 Passive Gravity Mass with Passive Gravity Mass = Inertial Mass in accord with the equivalence principle that only works for test masses in an external active mass gravity field. Experimental tests have been funded by Juan Feria, CEO of Texas Space, LLC Dallas.\n\nOn Thu, Sep 5, 2024, 12:59 Jack Sarfatti wrote:\nMEMORANDUM FOR THE HISTORICAL RECORD ON THE DISCOVERY OF 10^-2 GEV TABLE TOP QUANTUM GRAVITY 21 POWERS OF 10 LOWER THAN THE 10^19 GEV INSIDE DISPERSIVE ARTIFICAL LAYERED METASURFACES OF THE GROUP THINK OF CONVENTIONAL WISDOM IN THE PHYSICS COMMUNITY.

This work shows how gravity might emerge from quantum entanglement. However, this paper came out significantly after the work of Verlinde on entropic gravity so I still do not understand your point regarding what I wrote concerning Entanglement Entropic gravity.

My Stance is a bit more Nuanced here. There is a whole plethora of work here to Back up what you're doing beyond just Verlinde. Your paper with Jack Explicitly talks about Emergent Gravity from Entanglement Entropy, yes? Verlinde's 2010 paper on Entropic Gravity NEVER mentioned Entanglement, whereas Carroll and Jacobsen Do. It's one thing to derive GR from Black Hole thermodynamics, which is what Jacobsen initially did in 1995, Its another to derive it out of an Abstract Quantum State, (which is the focus of their later works) The works of Verlinde, Jacobsen, Carrol, etc are not contradictory but complementary.On Tue, Sep 3, 2024 at 5:22 PM Jose Rodal wrote:\n1) You missed the whole point. The point was NOT that he was teaching only 1 class.  My point was that he left Caltech because Carroll wanted to go beyond mathematical physics and he is only teaching a class in PHILOSOPHY because he is interested in philosophy. At this point in his career Carrol can teach as many or as few classes as he wants by heaven's sake :-)2) I did NOT say that the works of Sean Carrol are not interesting.  Again you missed the point.  The point was to contest your assertion that referencing Verlinde for entropic gravity was insufficient, and that one had to reference Carrol for entropic gravity.  I believe that's incorrect.  Carrol's career is NOT centered around entropic gravity.  Carroll had one influential paper on this topic of entropic gravity and I did cover his contribution (not by referencing Carroll because I did not get to the point to cite bibliography) but by going over his important finding: what is the entropy in entropic gravity:In 2016, Carroll and Grant Remmen published a paper titled \"What is the entropy in entropic gravity?\" This paper investigated theories where gravity arises as a consequence of entropy.\n\nThey distinguished between two approaches: holographic gravity and thermodynamic gravity, examining the assumptions and consistency of each.\nCarroll's work appears to be more focused on analyzing and critiquing existing entropic gravity theories rather than proposing a new one.\nJosé J.

To me, if we were to follow that line of logic, then we shouldn't listen to Jack's ideas either because he isn't teaching any classes.\n\nThat being said. I would Urge you to look into the topic beyond just \"these search results\"  \n\nThe provided papers are available together in Volume 2 of the Drive I sent in my initial Email to you and Jack. That drive is a Valuable resource for you and Jack to leverage in the specific work being pursued. It paints a clear line of research from Bekenstein through to Carroll. \n\nI believe it is very important to note that Verlinde's 2010 paper never actually makes any mention of \"entanglement\" .  However, Both Jacobson and Carrol explicitly work from the grounds of Extracting GR from quantum entanglement, (as noted below)(There is more cases beyond the above 3 papers)\n\nFurthermore, While Verlinde may have coined the term \"Entropic Gravity\" He was not the first to work on the issue (very similar to how Bryce Dewitt coined the term \"Many Worlds\" but we still call it Everettian QM not Dewittian QM).

In it five symbols a star, cross, circle, wavy line and square were oriented randomly in columns of 25.Four persons in the United States attempted to guess the order of the symbols. They were able to do this with success that could be duplicated by chance in one out of 3,000 experiments.\"\n\nHe claimed, in effect, that his demonstration showed that ESP (Extrasensory Perception) was independent of shielding, locale, distance, or time.\n\nWhen he got back to planet Earth, he founded The Institute of Noetic Science (IONS), noetic meaning consciousness studies. That program, now run by parapsychologist Dean Radin, is still thriving and the Institute recently moved to larger quarters in an old school in Petaluma, California.\n\nIONS is celebrating its 30th anniversary.\n\nMAKES ME WANT TO PSI\n\nThe spontaneous event commonly called psychic experience, perception or ability is called 'psi' in scientific arenas.\n\nEven more precisely, it is now often referred to as anomalous cognition (AC). A particular form of intentional AC is known as Remote Viewing. Between 1978-1995 the U.S. government sponsored the Stargate Program, in conjunction with Stanford Research Institute (SRI), a psyops development think tank.\n\nThe existence of psi or ESP abilities has been hotly debated among scientists for decades, since J. B. Rhine began his experiments in 1927.\n\nBoth the pro (Dean Radin; Ingo Swann; Jessica Utts, Russell Targ; Hiroshi Motoyama) and con (James Randi, Susan Blackmore, CSICOPS) positions have their \"true believers\", and it seems never the twain shall meet.\n\nPsi is still a paradigm that lives on the outskirts trying to become a sanctioned science. But just because a subject is controversial, and happens to be a space and time transcending experience, doesn't mean we shouldn't investigate it. In fact, it beckons us to focus on it even more thoroughly to reveal the truths hidden there. We simply need to do it with stringent, critic-proof methodology.\n\nThere are a variety of psi powers, known for centuries in Eastern philosophy as siddhas, exceptional human abilities.\n\nThe uninitiated or skeptical may be perplexed or daunted at the prospect of coming to any rational conceptual understanding of these anomalous phenomena, which have been associated with the realm of mysticism, superstition and the supernatural.\n\nIn actual fact, research by the authors, who are both certified hypnotherapists (A.C.H.E.), and others (Miller; Ryzl) shows that nearly anyone can improve their psi ability through simple techniques of self-hypnosis.\n\nPsi is also at the root of focused intent, distant mental interactions, distance healing and therapeutic rapport, where there is a subtle shared consciousness and often brainwave synchronization. This capacity is within everyone’s grasp, as the human potential movement demonstrated with such trance phenomena as fire walking and guided imagery.\n\nWe've virtually all had those uncanny or awesome experiences where we seemed to intuit, dream, or \"know\" something in advance of conventional means. Sometimes it is called pre-sentiment. Around 55% of reported incidents occur in dreams.\n\nAnother example, is the synchronicity at work in the affairs of \"star-crossed lovers.\"\n\nWhen we are in love, we seem to share the same \"wavelength,\" virtually able to read one another’s minds. Who hasn’t thought of a friend or acquaintance only to have the phone ring?\n\nOften the most compelling stories come from those who don't even \"believe\" in the phenomenon, but find themselves experiencing it, usually in the unfortunate circumstance of the illness, injury or death of a distant loved-one.\n\nPsi is not just a mental perception or conception; we feel it in our guts, in our bones, in our marrow. It is first and foremost a holistic mind/body experience.\n\nAccording to leading parapsychologist Dr. Stanley Krippner,\n\n\"At one level of investigation, there already are 'replications' and 'battle-tested' results, specifically the finding that about 50% of an unselected group will report having had a 'psychic experience,' supposedly involving those psi phenomena that have been given such labels as 'telepathy', 'clairvoyance', 'precognition', and 'psychokinesis' [mind over matter].This percentage may vary from one culture, age group, and educational level to the next, but it has been repeated, in one study after another, for the last several decades.\"\n\nThe move in biophysics is to take psi research from endless theorization, proofs of existence and boring replications into innovative and practical experimentation.\n\nThe problem is that in order to do that scientifically, one has to risk credibility and professional suicide, as well as being underfunded.\nOPEN SESAME\n\nThough it often seems confined to mediums, channels, sensitives, or ESPers, most individuals are capable of expressing some nonlocal communication or psi phenomena.\n\nHowever, that ability may be blocked for various reasons by an adaptation to consensus reality, to conventional thinking. We need to develop \"out of the box\" thinking. Even Einstein said that past, present, and future are illusions, even if they are stubborn ones. Conscious calculation rarely plays a role in ESP; the same is true for creativity.\n\nBoth ESP and creativity have deep taproots in the psyche. Pang and Forte (1967) found some evidence of a relationship between creativity and ESP, as did others (Honorton, 1967).\n\nFrederick Myers reported that a large proportion of ESP experiences occur in altered states such as dreams, trance, hypnosis and creativity while Masters and Houston (1966) counted it among the varieties of psychedelic experience.\n\nESP, hypnosis and mind-expanded states have sensitivity to the unconscious at their core. And that subconscious expresses itself through symbols, imagery, and sensations to communicate with the conscious mind. Hypnosis is the \"open sesame\" to the waking impressions and sensory images of the deeper mind/body.\n\nThe elusive ability to swing back 'the doors of perception' and enter the numinous realm of the collective unconscious was described by psychologist C.G. Jung. Whether deliberate or accidental, anyone can open to the force of this revealed process, to this dynamic information field. Those who frustrate themselves with self-defeating behavior in other areas of life often show poor psi performance.\n\nPositive ESP scores seem to correlate generally with traits such as openness, high self-esteem, warmth, sociability, adventuresomeness, relaxation, assertiveness, talkativeness and practicality. However, some psi-talented individuals often don't score well in laboratory settings.\n\nOn the other hand Russell Targ (1994) claims,\n\n\"[P]si is no longer elusive; it can be demonstrated when needed for study and investigation.\"\n\nEven though psychic training to strengthen the signal line is possible, unpredictability has been the hallmark of this emergent gift.\n\nTo overcome this problem in both the theoretical and experimental arenas requires a marriage of the disciplines of physics, biology, medicine, psychology, and hypnosis.\n\nFindings from all these fields converge in the paradoxical subject of Extra-Sensory Perception. As the ideas of quantum mechanics, relativity and parapsychology slowly make their way into our collective consciousness, our common-sense views on time and causality find themselves more strained than they've ever been in the course of human history.\n\nWill this challenge remain the domain of theoretical science, or can we foresee a day in which the general understanding, and even the experience of the average individual, will be shaped by this new perspective on reality? (Sidorov, 2003, \"The Mind In Time\").\n\nIt takes many disciplines, as well as the latest findings in physiology, neurobiology and information theory to begin to formulate any comprehensive understanding of the phenomenon and bridge the conceptual gap.\n\nESP used to be studied in Parapsychology, an adjunct of psychology. But its subject matter has become so mainstream, the field has been return to ordinary Psychology. ESP \"software\" is studied in psychology, but ESP \"hardware\" is the domain of biophysics.\n\nResearchers are probing the interface between matter, spacetime and mind with increasing precision. There is optimism that ultimately conventional pathways will be found to explain their appearance. Suggestions have included Schumann Resonance as a nearly-instantaneous carrier of psi information or perhaps paradoxical quantum nonlocality or coherence to account for it.\n\nThere are many models that provide potentially viable explanations. The mental aspects can perhaps be described psychologically, but the mechanics require models from physics. A variety of theories have been proposed, including neurological, holographic, electromagnetic, and quantum mechanics based hypotheses.\n\nLike electricity, no one knows how psi works.\n\nHowever, to foster and practice psi we don't need to know how it works, anymore than we need to know the mechanics of internal combustion to drive a car.\n\nWHAT IS PSI?\n\nThis month (July 2003) on the editorial board of the Journal of Non-Local and Remote Mental Interactions, we have been preparing a special issue on Remote Viewing.  \n\nStargate RV expert and teacher, Joseph McMoneagle is interviewed, along with such notables as author and theoretical physicist, Fred Alan Wolf, and Finnish physicist Matti Pitkanen.\n\nMany plausible theories and ","author":"Twitter for iPhone","url":"https://www.bibliotecapleyades.net/CIENCIA/ciencia_psycho07.htm","video_id":null,"domain":"Physics","depth":"Intermediate","duration_seconds":null,"source":"twitterapimcp","source_url":"https://x.com/i/status/2098462140977815953","discovered_at":"2026-09-16T14:23:06.910Z","published_at":"Fri Sep 11 17:22:16 +0000 2026","topic":"quantum field theory graduate course","transcript":[],"chapters":[],"score":1,"quality_reasons":["Educational format","Substantive source description","Subject relevance","Accessible talk format","Approachable level"],"title_en":"Extra Sensory Perception Navigation 432 CODE 571010","description_en":"Extra Sensory Perception Navigation 432 CODE 571010\nESPN\n10043 1121141 0141100112 2301030112 : 8111113\n\n8682555\n\n39\n\n12\n\n3\n\n\"One really should start thinking\n\nin terms of biomind receptors,\n\nrather than in terms of ESP\"\n\nIngo Swann\n\nSHOT IN THE DARK-SIDE OF THE MOON\n\nWhile on his journey to the moon and back, astronaut Edgar Mitchell conducted an unscheduled experiment of his own.\n\nOn June 22, 1971, he informed the New York Times that:\n\n\"During the Apollo 14 lunar expedition I performed an extrasensory-perception experiment the world's first in space.

classification of surfaces and Euler characteristic | Differential Geometry 25","description":"Here we give an informal introduction to the modern idea of `manifold', putting aside all the many logical difficulties that are bound up in this definition: difficulties associated with specification, with the use of `infinite sets', with the notions of `functions' etc. \n\nEven those students who aspire to understanding mathematics correctly ought to be at least aware of the standard formulations, and if one is teaching a course at a major university these days one is limited by the curriculum and the orientation of students and other lecturers in the level of directness that one may address these foundational problems.\nI will eventually be discussing the difficulties with these concepts in the MathFoundations series.   \n\nIn this lecture we talk about charts, manifolds, orientation, and then look more carefully at the two dimensional case of compact surfaces, where things are more concrete and explicit, largely through the classification of Dehn and Heegard which utilizes in a major way the Euler characteristic.\n\n***\nResearch Gate page:

What matters is how the object is connected.\n​The Golden Rule: Bend, Don't Break\n​To think like a topologist, imagine everything is made of infinitely stretchy, high-quality Play-Doh.\n​Allowed: You can stretch it, squish it, twist it, and bend it as much as you want.\n​Forbidden: You cannot tear it apart, and you cannot glue distinct parts together.\n​If you can transform Shape A into Shape B using only \"Allowed\" moves, those two shapes are considered topologically equivalent (or homeomorphic).\n​The Classic Example: Coffee Cup = Donut\n​The most famous joke in topology is that a topologist is someone who cannot tell the difference between a coffee mug and a donut.\n​The Donut (Torus): Imagine a standard donut. It has one hole in the center.\n​The Coffee Mug: Imagine a clay coffee mug. It has a cup part and a handle.\n​The Transformation:\n​Push the bottom of the cup up until it fills the bowl. Now you have a lump of clay with a handle (a loop).\n​Thicken the handle and smooth out the lump.\n​You are left with a ring shape—a donut.\n​Because you didn't tear the clay or drill a new hole, the mug and the donut are the same thing to a topologist. They are both surfaces with genus 1 (one hole).\n​Counter-Example:\nYou cannot turn a ball (sphere) into a donut without ripping a hole in the middle. Therefore, a sphere and a donut are not topologically equivalent.\n​Key Concepts\n​1. Topological Invariants\n​These are the properties that stay the same during deformation. They are used to classify shapes.\n​Number of Holes: A shirt with no holes is different from a shirt with holes. (Note: In topology, a \"hole\" usually refers to a tunnel, like a straw, rather than a depression).\n​Connectedness: Is the object one piece, or is it split into separate islands?\n​Compactness: Is the shape \"contained\" and finite (like a sphere), or does it go on forever (like an infinite plane)?\n​2. Homeomorphism\n​This is the mathematical term for \"equivalence.\" If there is a continuous function that maps Shape X to Shape Y, and a continuous inverse function that maps Y back to X, the two shapes are homeomorphic.\n​3. Manifolds\n​A manifold is a shape that, when you zoom in really close, looks like flat Euclidean space (the kind of geometry you learn in high school).\n​Example: The Earth is a sphere (topology), but to a human standing in a field, it looks flat (Euclidean). This makes the surface of the Earth a \"2-manifold.\"\n​Major Branches\n​Point-Set Topology (General Topology): The foundation. It deals with abstract definitions of \"nearness,\" limits, and continuity without necessarily using distance.\n​Algebraic Topology: Uses abstract algebra (groups and rings) to count holes and measure complexity. It turns geometric problems into algebra problems that are easier to solve.\n​Differential Topology: Studies smooth surfaces (manifolds) where you can use calculus. It is essential for modern physics.\n​Knot Theory: The study of mathematical knots. Unlike a shoelace knot, mathematical knots are loops with no ends. The goal is to determine if a tangled loop can be untangled into a simple circle without cutting.\n​Why Does This Matter? (Applications)\n​Topology is not just abstract nonsense; it is used extensively in modern science.\n​Data Science (Topological Data Analysis - TDA):\nBig data is often high-dimensional and messy. Topology helps find the \"shape\" of data. For example, it can look at a cloud of data points and determine if they form a loop, a cluster, or a void, which might indicate a recurring pattern (like a seasonal cycle in sales data).\n​Biology:\n​DNA: DNA strands are long and get knotted inside the cell nucleus. Enzymes called topoisomerases cut and re-glue DNA to untangle it. Biologists use knot theory to understand this process.\n​Protein Folding: The specific 3D folded structure (topology) of a protein determines its function.\n​Physics:\n​Topological Insulators: These are strange materials that conduct electricity on their surface but block it on the inside. This property is \"protected\" by topology, meaning it is robust against defects and damage. This is a massive area of research for future electronics and quantum computers.\n​Cosmology: Physicists use topology to study the overall shape of the universe. Is it a sphere? Is it flat? Is it a donut?\n​Robotics:\nEngineers map out the \"configuration space\" of a robot arm. If a robot has 3 joints, its possible positions form a complex topological shape. Finding a path from A to B without hitting an obstacle is a topological problem.","likes":1,"url":"https://www.youtube.com/watch?v=qgCPjVxnDPo&lc=UgxoksZUU2BulC1C9f14AaABAg"},{"id":"UgzrzzYR3nUJblw0j054AaABAg","author":"@vysakh811","text":"👍","likes":2,"url":"https://www.youtube.com/watch?v=qgCPjVxnDPo&lc=UgzrzzYR3nUJblw0j054AaABAg"},{"id":"Ugzo3pvo6T4bWjhxMUt4AaABAg","author":"@freeman4899","text":"Very informative but my suggestion is make videos shorter and avoid saying same thing again again.","likes":4,"url":"https://www.youtube.com/watch?v=qgCPjVxnDPo&lc=Ugzo3pvo6T4bWjhxMUt4AaABAg"},{"id":"UgygP09nizOpWfexOat4AaABAg","author":"@sumantramajumder281","text":"very good coverage ... but details needs more clarity, depth and good illustrations (please use atta/maida over a black background - will be much cheaper).

This proposition makes use of some newly developed concepts based on non-Hermiticity and parity-time (PT) symmetry-ideas first conceived within quantum field theories. By harnessing such notions, recent works indicate that novel synthetic structures and devices with counter-intuitive properties can be realized, potentially enabling new possibilities in the field of optics and integrated photonics. Non-Hermitian degeneracies, also known as exceptional points (EPs), have also emerged as a new paradigm for engineering the response of optical systems. In this talk, we provide an overview of recent developments in this newly emerging field. The use of other type symmetries in photonics will be also discussed.\n\nBio: \nDemetrios Christodoulides is the Cobb Family Endowed Chair and Pegasus Professor of Optics at CREOL-the College of Optics and Photonics of the University of Central Florida.

He then gives an overview of two well-studied families of chaperones, heat shock protein 60 (Hsp60) and Hsp70. In Part 1 B, Horwich continues with a review of the Calnexin, Hsp90 and small Hsp families.\nHe discusses how transcriptional regulation in response to chemical or heat stress results in an increase in effector chaperonins.  Finally, Horwich poses the question of why chaperonins are not effective in preventing protein aggregation or misfolding in a number of devastating neuronal diseases. \nHorwich discusses experiments designed to decipher how chaperones mediate protein folding in Part 2 of his talk.  He describes in detail the role of ATP binding and hydrolysis by the GroEL/GroES complex in promoting correct protein folding. \nIn Part 3, Horwich describes the experiments that determined that proteins are, in fact, folded within the chaperonin complex and exactly where folding occurs.\n\nSpeaker Bio:\nArthur Horwich received his AB and MD from Brown University.  Following a pediatric residency at Yale, Horwich did two postdoctoral fellowships, first with Tony Hunter and Walter Eckhart at the Salk Institute and second with Leon Rosenberg at Yale, before joining the Yale faculty.   \nCurrently, Horwich is Sterling Professor of Genetics and Pediatrics at Yale School of Medicine and an Investigator of the Howard Hughes Medical Institute.  He is interested in understanding how chaperonins promote the correct folding of proteins in the cell.  More recently, Horwich has focused his efforts on understanding the consequences of protein misfolding, particularly in ALS or Lou Gehrig's disease. \nHorwich is a member of the National Academy of Sciences and has received numerous awards for his work including the Gairdner International Award.  Together with his long time collaborator Franz-Ulrich Hartl, Horwich has been awarded the Wiley Prize, the Louisa Gross Horwitz Prize and the Albert Lasker Award for Basic Medical Research, among other prizes.","author":"Science Communication Lab","url":"https://www.youtube.com/watch?v=jOhNyVjkChM","video_id":"jOhNyVjkChM","domain":"Biology","depth":"Intermediate","duration_seconds":2289,"source":"serperdevmcp","source_url":"https://www.youtube.com/watch?v=jOhNyVjkChM","discovered_at":"2026-09-14T04:12:37.437Z","published_at":"Jan 21, 2014","topic":"molecular biology protein folding lecture","transcript":[],"chapters":[{"at":0,"title":"Chaperone-assisted protein folding"},{"at":263,"title":"\"Smooth\" energy landscape of a protein folding reaction"},{"at":360,"title":"Conclusion: For many proteins, and under cellular conditions, folding is kinetically difficult; Anfinsen's principle correct that primary sequence directs folding to an energetic minimum, but chain"},{"at":1013,"title":"Bacterial GroEL/GroES-mediated protein folding was reconstituted in a test tube"},{"at":1197,"title":"Polypeptide binding - a hydrophobic surface"},{"at":1575,"title":"How do chaperones recognize hundreds of different non-native proteins?

There is a constant flow of ideas from type theory to programming (and back). We are familiar with algebraic data types; inductive types, like lists or trees; we've heard of dependent types and, in the future, we might encounter identity types and possibly get familiar with elements of homotopy type theory.\nI can't possibly talk about all of this, but I'll try to give you a little taste.

One of the preferred formalisms in proof theory for building deductive systems is Gerhard Gentzen's sequent calculus formalism. This talk is intended as an introduction to proof theory and will introduce a variant of Gentzen's sequent calculus for classical propositional logic. Moreover, the sequent calculus will be used to demonstrate and define fundamental proof theoretic notions such as sequents, types of inference rules, methods of soundness and completeness, and properties of calculi.","author":"Computational Logic Group TU Dresden","url":"https://www.youtube.com/watch?v=grjMRgmjddE","video_id":"grjMRgmjddE","domain":"Mathematics","depth":"Intro","duration_seconds":3519,"source":"serperdevmcp","source_url":"https://www.youtube.com/watch?v=grjMRgmjddE","discovered_at":"2026-09-12T20:00:26.829Z","published_at":"May 1, 2021","topic":"mathematics proof theory lecture","transcript":[],"chapters":[{"at":0,"title":"Why Proof Theory?"},{"at":107,"title":"Structure of Talk"},{"at":185,"title":"Language and Semantics"},{"at":287,"title":"Axiomatization"},{"at":620,"title":"What are Sequents?"},{"at":752,"title":"How are Sequents Interpreted?"},{"at":896,"title":"The Sequent Calculus Lcp"},{"at":1611,"title":"Derivations/Proofs"},{"at":1930,"title":"Types of Soundness and Completeness"},{"at":2020,"title":"Strong Soundness"},{"at":2090,"title":"Soundness Example"},{"at":2324,"title":"Completeness: via Hilbert System"},{"at":2528,"title":"Types of Rule Redundancy"},{"at":2845,"title":"Height-Preserving Admissibility"},{"at":2920,"title":"Eliminability"},{"at":3098,"title":"Hp-admissibility of (WL)"},{"at":3356,"title":"Conclusion and Future"}],"score":1,"quality_reasons":["Educational format","Substantive source description","Subject relevance","Accessible talk format","Approachable level"],"author_url":"https://www.youtube.com/@computationallogicgrouptud9652","thumbnail":"https://i.ytimg.com/vi/grjMRgmjddE/hqdefault.jpg","channel_id":"UCYkAWw6vtFH0C6LHc93QGow","comments":[{"id":"UgwTWgMZBoTyDzNkZUx4AaABAg","author":"@vaibhavkhobragade9773","text":"Great very helpful.

I will post answer at the end of the message.\n\nFrom the late 2000s to the mid-2010s, I worked as a molecular biologist for a national security contractor in a program to study Exo-Biospheric-Organisms (EBO). The aim of the program was to elucidate the genome and proteome basis of these organisms. Although the study of OBCs has been going on for decades in other programs, the new high-throughput DNA sequencing technologies of the late 90s unblocked stagnant research in this area. Since then, several breakthroughs have led to significant advances in our understanding of the genome and proteome of these beings. What we've learned so far has enabled us to outline some disconcerting perspectives about our place in this universe. Briefly, we've discovered that the EBO genome is a chimera of genomes from our biosphere and from an unknown one. They are artificial, ephemeral and disposable organisms created for a purpose that still partially eludes us. I'll be substantiating my statements after a brief introduction.\n\nThe reason for disclosing these secrets is quite simple. I believe that every human being has the right to know the truth, and that to progress, humanity needs to divest itself of certain institutions and organizations that will probably not survive these revelations in the long term. I'm aware that I'll have very little impact in this regard, but I still believe that small leaks are necessary to break the dam of misinformation on this subject. When the governments will eventually reveal these secrets, there will undoubtedly be a societal upheaval, but in my opinion, the longer we wait, the worse it will be. I choose to divulge what I know anonymously out of selfishness for the well-being of myself and my family. I'm aware that this diminishes the reach and credibility of my message, but it's the furthest I am willing to go. I chose this forum because it offers a good compromise between anonymity and popularity. In order to protect my anonymity, I will be purposely vague or even contradictory about any information that could identify me (date, education, role etc.). I'll even introduce red herrings in this respect. I want to make it clear that any information related to the subject of the research will not be treated in this way.\n\nBefore going any further, please excuse me if you find it difficult to understand what I'm explaining. Some parts of my text are very technical. It's difficult to find the right balance between vulgarization and scientific explanation. I'll continue by talking about myself. What's the point of talking about me knowing that the information will necessarily be misleading? I simply want to introduce a perspective on the type of people who work there, normal scientists. I have a Ph.D. in molecular biology. I didn't actively seek to be part of this program, rather it was a stroke of luck that introduced me to one of the senior scientists. I met this person at a conference where I was presenting a poster on my Ph.D. research. When I think back, I don't believe he was impressed by what I was presenting, because it was quite frankly a project that wasn't going anywhere. I think it was rather the most important aspect of a professional life: the attitude and the ease with which you make connections. Shortly afterwards, I graduated and received a call from this person offering me a position. At the time, everything pointed to me working in a regular laboratory.\n\nI did a series of three increasingly suspicious interviews, each in a different location, where my scientific background and knowledge became less and less relevant. The first was with two of the senior scientists, the second and third with people I've never seen again and who were obviously not interested in science. Sometime after the interview, I was asked to go to a fourth location where what seemed like a corporate lawyer presented me with an NDA. He made sure not only to explain every detail, but also that I understood the consequence of not respecting it.\n\nThe first Employment weeks were by far the most memorable, although I spent most of that time in a depressing archive room. It consists almost exclusively of reading about the subject of study and to get us up to speed. There's no secret Wikipedia or even a reference book to guide us. There are only dry reports, memos, presentations, procedures and SOPs. These documents are almost exclusively about the biology of EBOs, but there are also a few that deal with other subjects such as their food, religion or culture. There were no documents on their technology.\n\nAs mentioned above, the aim of the project is to gain a better understanding of the EBO genome and proteome. To achieve this, a team of around twenty scientists, four senior scientists and a director was involved. The scientists, like myself, had as their main responsibility to carry out the technical work. As each scientist had to my knowledge a Ph.D., we were all somewhat overqualified for what is ultimately a technician's job. The senior scientists, who make full use of their diplomas, had the task of designing the assays and had a supervisory responsibility. They were also in charge of training new employees, and sometimes even came in to do technical work. The director, of course, was the person in charge who dictated priorities to the senior scientists. He was rarely on site, and the few times he was, it was to attend meetings. Other than the scientific staff, there were security guards working for one subcontractor or another. There were no support staff such as janitors or maintenance workers. Scientists were responsible for this kind of work. In addition, logistical constraints ensure that every scientist is capable of carrying out any technical activity.\n\nThe laboratory itself is located in Fort Detrick, Maryland, in a building used for legitimate biomedical research. The clandestine operations are carried out in a restricted part of the basement, out of sight from regular workers. Contrary to what one might imagine, the biosafety level is not maximal for this type of research. Indeed, the lab containing EBO samples or derived cell cultures is BSL3, while the lab where assays are conducted are only BSL2. The BSL3 area of the facility includes a freezer room and a cell culture lab and is only accessible through an antechamber from the BSL2 section. EBO carcasses are preserved in horizontal freezers at a temperature of -80°C nominal. To maximize the preservation of these carcasses, they are preserved in vacuum bags and the air in the room is controlled to minimize humidity. There are only four bodies and none of them are complete. It's obvious that these creatures have died as a result of major trauma. I've never witnessed a motorcycle accident fatality, but it probably looks similar to this. It is acknowledged that there are more EBOs caracasses at other locations. The cell culture laboratory, as its name suggests, is where cell lines derived from EBOs are grown and related activities are performed. I'll talk in more detail about these specific cell lines later on. The BSL2 part is mainly used for assays, immunohistochemistry, genetic engineering, immunocytochemistry, storage etc. There's also a cell culture lab, but this is used for more traditional cell lines. Other than the labs, there are all the amenities you could find in an office. Note that the internet access is limited to senior staff and up. There is, however, an intranet for bioinformatics needs.\n\nOn the subject of the biology of these beings, I'll start by discussing genetics, then their gross anatomy and finally their biological systems. For the sake of clarity, the information that I provide here is an aggregation of what I have observed and what I have read. I will make many comparisons with human anatomy because it is the most logical reference.\n\nGenetics:\n\nFirst, I'd like to discuss their genetics. Their genetics are like ours, based on DNA. This fact was very puzzling for me when I first learned about it. We imagine that beings from an alternate biosphere would have genetics based on a completely foreign biochemical system and surprisingly, this is not the case. Several conclusions can be drawn from this surprising revelation. The one that immediately comes to mind is that our biosphere and theirs share a common ancestry. They're eukaryotes, which means their cells have nuclei containing genetic material. Which suggests that their biosphere would have been separated from ours sometime after the appearance of this type of organism. The term Exo-Biospheric-Organism is actually a misnomer, but as it's a historical term, it's still used. Their genetics are not only based on the same genetic system, but they’re also even compatible with our own cellular machinery. This means that you can take a human gene and insert it into an EBO cell, and that gene will be translated into protein, and this of course works in reverse with a human gene inserted into an EBO cell. There are important differences in post-translational modifications that will make the final protein non-functional, but I'll discuss these later. Their genome consists of 16 circular chromosomes.\n\nYou're probably familiar with the concept of intergenic region or \"junk DNA\". These are basically DNA sequences that don't code for proteins. These are evolutionary residues, transposons, inactivated genes and so on. To give you an idea, in humans, intergenic regions represent approximately 99% of our genome. I'm aware that these sequences aren't completely useless, they can be used as histone anchors, as buffers to protect coding DNA from radiation or","author":"Twitter for iPhone","url":"https://www.reddit.com/r/aliens/comments/14rp7w9/from_the_late_2000s_to_the_mid2010s_i_worked_as_a/","video_id":null,"domain":"Biology","depth":"Intermediate","duration_seconds":null,"source":"twitterapimcp","source_url":"https://x.com/i/status/1676831818874494976","discovered_at":"2026-09-12T05:12:56.347Z","published_at":"Thu Jul 06 05:53:54 +0000 2023","topic":"biology genetics research explained","transcript":[],"chapters":[],"score":1,"quality_reasons":["Educational format","Substantive source description","Subject relevance","Accessible talk format","Approachable level"],"title_en":"https://t.co/JyuR7N64kg","description_en":"From the late 2000s to the mid-2010s, I worked as a molecular biologist for a national security contractor in a program to study Exo-Biospheric-Organisms (EBO).

If you haven't heard of it, there's a intimately related field called Projective Geometric Algebra. It applies the constructions of Geometric Algebra to Projective Geometry. This allows you to easily define projective points as vectors, projective lines as bivectors, and projective planes as trivectors. This allows you to use the wedge product in GA similarly to how you were using the direct sum, which also makes the construction at 18:40 come a little easier. B is the bivector representing the plane spanned by the two vectors in A (this also follows from how B is the normal vector to the plane spanned by A, and normal vectors don't transform as vectors but rather as bivectors).\nEric Lengyel has done research in expanding PGA to include a new operation he called the antiwedge product, which performs an operation analogous to the intersection use here. Along with some other operations. It gets complicated extremely quickly, but it's a neat rabbit hole to follow. He's also applied PGA to video game math in his C4 Engine.","likes":47,"url":"https://www.youtube.com/watch?v=dPWTZSC7PYI&lc=UgyoqGQGEjgzf_OeVmJ4AaABAg"},{"id":"UgybBUbPX9_jjjMlEox4AaABAg","author":"@maxpercer7119","text":"This is great,  many advanced treatments of projective geometry rush through nitty gritty details (such as the ray versus the line issue for a point at infinity).","likes":3,"url":"https://www.youtube.com/watch?v=dPWTZSC7PYI&lc=UgybBUbPX9_jjjMlEox4AaABAg"},{"id":"UgwBWQYzTt2-2P8FaRR4AaABAg","author":"@friese4829","text":"Really liked the video!

College courses, however, are often sold by title and catalog description alone. Students register for “Introduction to History,” “Ethics,” or even a science requirement with little idea of the intellectual assumptions the professor will bring into the lecture hall.\n\nThat information can be consequential. A course may pursue knowledge through evidence and argument. It may also subordinate the subject to diversity, equity, and inclusion programs, critical theory, gender ideology, Marxist assumptions, or some other political project.\n\nIdeological activism is not confined to philosophy, literature, or religious studies. It increasingly appears across the curriculum, including in professional programs and “hard” scientific fields.\n\nParents and students have every right to know whether a professor intends to teach the advertised subject, examine competing arguments, and permit disagreement — or use the classroom to promote a political worldview.\n\nThe concern is especially urgent at public universities. Faculty members at state institutions are government employees paid by taxpayers. In Arizona, for example, they undertake obligations to uphold the United States and state constitutions. Taxpayers are therefore entitled to ask whether professors are educating students for citizenship in a constitutional republic or teaching theories fundamentally hostile to it.\n\nThat’s why I developed what I call the “Intellectual Nutrition Label.”\n\nThe idea is simple. A nutrition label does not order shoppers to buy or reject a product. It tells them what the product contains so they can decide for themselves. The Intellectual Nutrition Label would do the same for college professors and courses.\n\nUsing public information — university biographies, curricula vitae, books, articles, interviews, lectures, and course materials — each label would summarize the intellectual content students are likely to encounter. Families should not need graduate training or weeks of research to understand what a professor openly teaches.\n\nA useful label might ask:\n\n- Does the professor encourage the pursuit of knowledge or deny that objective truth exists?\n\n- Does the course cultivate virtue and self-command or treat desire as its own justification?\n\n- Does it direct students toward goodness, beauty, and wisdom or toward resentment, envy, and contempt?\n\n- Does the professor teach students how to examine arguments or tell them which political conclusions a decent person must reach?\n\nA label could also rate qualities such as intellectual honesty, knowledge, virtue, beauty, meaningfulness, and piety. A professor might rank highly for candor and scholarship while receiving a low rating for piety because he publicly rejects belief in God. The point would not be to uncover private opinions or publish anonymous accusations. The ratings would summarize what professors already say about themselves and their work.\n\nThat distinction is essential. An Intellectual Nutrition Label should not become a blacklist, an invitation to harassment, or a substitute for reading a professor’s work. It must rely on verifiable public evidence, represent a professor’s position fairly, and provide enough sourcing for readers to check the judgment for themselves.\n\nThe concept has predecessors. David Horowitz’s 2006 book, “The Professors: The 101 Most Dangerous Academics in America,” documented ideological activism in higher education. The David Horowitz Freedom Center continues to track left-wing activists and organizations. Turning Point USA’s Professor Watchlist sought to alert students to professors who brought political activism into the classroom and briefly maintained a list of recommended faculty.\n\nThe Intellectual Nutrition Label would have a narrower purpose: consumer disclosure. It would tell students and parents what intellectual ingredients a professor publicly advertises, in a format ordinary people can understand before registration day.\n\nIf a professor teaches that the United States is inherently oppressive, advocates Marxist critical theory, rejects biological sex as fixed, or treats Christianity principally as an instrument of domination, those positions should be documented in the professor’s own publications, biography, lectures, or course materials. An accurate summary of publicly stated beliefs is not censorship.\n\nThe more serious objection may be that parents and taxpayers were never expected to notice. Academic language often conceals radical assumptions behind specialized vocabulary. Professors can signal their commitments to colleagues while students discover the course’s real content only after enrollment.\n\nThat arrangement is losing its protection. Parents increasingly ask what their children are learning. Taxpayers increasingly ask whether public universities are educating students or recruiting them into political movements. Those are legitimate questions, especially when a single semester can cost more than many families earn in months.\n\nThroughout the coming semester, I will publish Intellectual Nutrition Labels evaluating professors from publicly available evidence. The labels will not decide which courses students may take. They will help families make that decision with their eyes open.\n\nReaders can follow the project on my Substack and at https://t.co/dWW6infYzZ (coming soon).\n\nWhen families spend tens of thousands of dollars on a college education, they deserve to know who is teaching, what that professor believes, and which intellectual ingredients will be placed before their children. Colleges already label the price. It’s time to label the product.\n\nhttps://t.co/qFk1rJ1MSe","author":"Twitter for iPhone","url":"http://intellectualnutritionlabel.com/","video_id":null,"domain":"Philosophy","depth":"Intermediate","duration_seconds":null,"source":"twitterapimcp","source_url":"https://x.com/i/status/2084617260019183698","discovered_at":"2026-09-11T22:00:01.320Z","published_at":"Tue Aug 04 12:27:39 +0000 2026","topic":"philosophy knowledge university lecture","transcript":[],"chapters":[],"score":1,"quality_reasons":["Educational format","Substantive source description","Subject relevance","Accessible talk format","Approachable level"],"title_en":"Warning: This college course may be bad for your brain | Owen Anderson, Blaze Media","description_en":"Warning: This college course may be bad for your brain | Owen Anderson, Blaze Media\n\nAn ‘intellectual nutrition label’ could warn students when a professor’s public record points toward indoctrination rather than intellectual inquiry.\n\nEvery August, families spend tens of thousands of dollars on college tuition, housing, meal plans, and textbooks.

We start at the very beginning with a refresher on the “rise over run” formulation of a slope, before converting this to the formal definition of the gradient of a function. We then build up some tools for making calculus easier, as well as generalising the concepts to multidimensional systems. Next, we learn how to calculate vectors that point downhill on surfaces and show how this is used for training neural networks using an interactive game. We take a look at how we can use calculus to build approximations to functions, as well as helping us to quantify how accurate we should expect those approximations to be. We finish the course by bringing all of these concepts together by showing you how to use code to fit a function to some data in a process known as non-linear regression. \n\nThis course was designed to help you quickly build an intuitive understanding of calculus, as well as the language necessary to look concepts up yourselves when you get stuck; it is not intended cover all the details.

For more information on the course and to access the full experience, please visit: https://www.coursera.org/specializations/mathematics-machine-learning\n\nFull Playlist - https://www.youtube.com/playlist?list=PLiiljHvN6z1_o1ztXTKWPrShrMrBLo5P3\n\nYour course instructors are\n- Dr David Dye (@DavidDye9, https://twitter.com/DavidDye9) \n- Dr Sam Cooper (@camsooper, https://twitter.com/camsooper)\nIf you have any questions about the course, please contact the instructors via Twitter. \n\nThis course offers an introduction to the linear algebra required for common machine learning techniques. We start by looking at some simultaneous equations problems and showing how these can be expressed using vectors and matrices. We then move on to exploring vector spaces and see how these can be reformulated by changing basis. Next, we explore some methods for manipulating matrices and see how this is done using code, before moving on to some special cases shown using interactive animations. In the final module, we bring all the concepts together to recreate Google’s famous PageRank algorithm, which uses eigenvectors to rank search result by their connectivity. \nThis course was designed to help you quickly build an intuitive understanding of calculus, as well as the language necessary to look concepts up yourselves when you get stuck; it is not intended cover all the details.

He was my loyal friend and a great visionary of neurosurgery and the basal ganglia. He was described as a wondrous amalgam of striking contrasts, complexities, clinical acumen, charisma, and bad luck by Crossman, Aziz and Stein. One thing I will personally never forget about him was his brilliance which was always accompanied by kindness. Once when he invited me to Oxford, he arranged for me to stay at his college, however the plans changed when he shared he was dismissed from his college just like Oscar Wilde. Yes, Oscar Wilde like Tipu Aziz was temporarily banned from the Common Room (lounge) at Magdalen College, Oxford—but he was not expelled from the university or the college itself. Wilde’s along with Aziz's nonconformity rubbed some of the more traditional fellows the wrong way. That was Tipu. He relished being in the same company as Oscar Wilde. Here is his obituary from Movement Disorders Clinical Practice.\n-It is with great sadness that we report his death from esophageal cancer after a 3-year period confined to a wheelchair following a head injury.\n-Tipu was born in Dhaka (aka Dacca) in 1956, moving with his family to the United States in 1957, where he grew up until 1963, when his father took a position at the Medical Research Center, Lahore in Pakistan. It was in Lahore in 1965 that Tipu witnessed the war between India and Pakistan, taking shelter at a hospital when things came too close for comfort—otherwise, for entertainment with his siblings, watching dogfights between fighter planes. Soon after the conflict ended, --Tipu moved back to Dhaka, then in East Pakistan, with his mother, two sisters, and younger brother, only to find himself in the midst of the horrors of civil war in the days after Liberation. It is likely that the atrocities that --Tipu had witnessed led to his evolving, paradoxically, an almost saintly calm and resilient approach to violence and evil as sad facts of life. He found that he simply had to accept and assimilate them, as he said, “as a little brown person with no particular importance in life.” He adored his mother, whose strong social conscience he had inherited, and this added to his personality a powerful determination to somehow do some good in this world of sorrows.\n-In 1971, in the newly created country of Bangladesh, the educational system was in turmoil. Tipu's mother was advised by his teachers to take her children abroad for a proper education. In light of this advice and the traumatic experiences of her children, in 1973 she once again moved with the four children—this time to Oxford, UK, for a fresh start.\n-Tipu was very proud of his father, Dr. Mohammed Abdul Aziz, who carried out the first clinical trials that demonstrated that the drug ivermectin could cure river blindness (onchocerciasis). He would probably have been awarded the Nobel Prize for that discovery, which was awarded in 2015, had he not died young in 1987.\n-Tipu particularly admired his father's devotion to properly organized scientific method. Generations of Tipu's students will have good reason to be thankful for Tipu's adoption of that principle.\n-In Oxford, Tipu devoted himself to science A-levels and then progressed to study Physiology at University College London, graduating with First Class Honors in 1978. Under the strong influence of Nobel Prize winners Bernard Katz and Andrew Huxley, both of whom he met personally, he decided that he wanted to be an electrophysiologist. He thus carried out a prizewinning dissertation on the neuromuscular junction of the barnacle. Characteristic of Tipu, he ever after sought out restaurants all over the world that served barnacles! -But Tipu always had a wide range of interests, and he found the time, during the same period, to take War Studies classes and also to study the history of neuroscience, and of smoking.\n-Dissatisfied with the limited lifestyle of the barnacle, Tipu then decided he needed to study medicine en route to his now-chosen career of neurosurgery. He won a place at King's College medical school and then carried out house and registrar jobs all over the country. In the early 1980s, Tipu was working as a Senior Registrar in Bristol. He contacted Prof. Alan Crossman, out of the blue, saying that he wished to pursue a career in functional neurosurgery, and he was interested by the work that Alan was doing in Manchester on movement disorders, including Parkinson's disease (PD). Tipu asked to come and work with him. Alan replied that, although he was very flattered to be asked, currently he had no funding for an extra position. Characteristically, Tipu replied, “Never mind. I will come and work with you for free!” And this he did. Fortunately, the work of the group was well regarded and that, together with Tipu's excellent CV, meant that he soon did gain a salary, as a Research Associate funded under the group's Medical Research Council Programme Grant.\n-It had recently been demonstrated in Alan's laboratory that, in animal models of PD, there was overactivity of the internal segment of the globus pallidus (GPi). They had also demonstrated that this was due to concomitant overactivity of the subthalamic nucleus (STN) through its excitatory, glutamatergic projection to the GPi. In 1990, they showed that pharmacological blockade of this projection, by injection of a glutamate antagonist into the GPi, alleviated the motor symptoms of parkinsonism.1 In the same year, the group of Mahlon DeLong in Atlanta demonstrated the antiparkinson effect of injection of the excitotoxin ibotenic acid into the STN.2 Neither of these crucial proof-of-concept studies used a method with direct applicability to the clinic.\n-As a consequence, Tipu became the first person in the world to show that lesioning the STN, using a technique routinely available in clinical neurosurgical facilities, immediately, completely, and permanently abolished all motor symptoms of parkinsonism.3 This pivotal work formed the basis of Tipu's MD thesis, the degree being awarded in Manchester in 1992. Tipu's work in Manchester convinced him that he should champion the use of animals in research, taking great personal risk, but determinedly pursuing what he felt was best for patients who needed help.\n-In 1992, Tipu was appointed as Senior Registrar in Neurosurgery at Oxford. During the interview, he impressed lead consultant Chris Adams by not only his academic and clinical prowess but also knowing the name of the artist who had drawn the sketches of neurosurgical anatomy displayed on the walls of the Cairns Suite at the John Radcliffe Hospital! This little anecdote is illustrative of Tipu's depth of knowledge of art and history, which few appreciated, seeing him, as they did, as a committed surgeon and researcher. Chris Adams was interested in deep brain surgery and invited Tipu to set up a service in Oxford. In those early years, workaholic Tipu found himself simultaneously setting up the Service in Oxford, creating a similar one in the Charing Cross Hospital in London, running a primate laboratory in Oxford, and contributing to the routine on call neurosurgery demand for the Oxford area.\n-Tipu had the drive and imagination to see how his pivotal experimental work in Manchester should be translated into the development of deep brain stimulation (DBS) of the STN for the treatment of PD, the first successful procedure being performed by Benabid and Pollak in 1993. In the region of 150,000 PD patients have now undergone this procedure, and Tipu performed a significant number of them himself. One of his star patients was Mike Robbins. Mike had a most disabling and incapacitating tremor, which was completely relieved when he switched on his STN DBS. You can see the dramatic result online (video is available at: https://t.co/khh8nFxpTa).\n-Mike was a remarkable man in that he appeared on television and at lecture events, turning off his stimulator and then on again, explaining, “Without Tipu's research performed on animal models of Parkinson's disease, this is what I would be like.” This, and similar presentations, convinced the celebrated animal rights campaigner Peter Singer that Tipu's experiments on monkeys were justifiable because the results improved so many people's lives. This was at the peak of animal rights groups’ attacks on Tipu.\n-Tipu was appointed as Professor of Neurosurgery in 1995. He was renowned for his calm and competence when clipping circle of Willis aneurysms. When they leaked during surgery, his technique was to apply a swab to it, leave the table, smoke a cigarette, and then return to the table. Most times the bleeding was now under control! Despite these skills, he later collaborated enthusiastically with Andy Molyneux to render them redundant by relegating to history books the technique of clipping most aneurysms.\n-Tipu's research in Oxford centered on improving the targeting of sites in the basal ganglia for alleviating the symptoms of PD and also for cerebellar tremors and multiple sclerosis. He speedily discovered that this could be done best by recording the field potentials from the tip of the stimulating electrode, rather than attempting to record from single basal ganglia neurons with microelectrodes, a procedure that adds several hours to the operation. Tipu regularly amazed visiting surgeons by performing it in under half an hour. More recently, he showed that careful planning of the proposed electrode track on the basis of diffusion tensor imaging (DTI) tractography of each individual patient's basal ganglia connectivity reaped even better results.\n-Tipu then went on to show how clever use of individualized DTI could also improve outcomes for the treatment of dystonia, together with another of his interests—DBS of the brainstem pain matrix for chronic pain, particularly in end-stage cancer. Serendipitously, this work also led him into studying the brainstem pedunculopon","author":"Twitter for iPhone","url":"https://movementdisorders.onlinelibrary.wiley.com/doi/10.1002/mds.30201","video_id":null,"domain":"Interdisciplinary","depth":"Intermediate","duration_seconds":null,"source":"twitterapimcp","source_url":"https://x.com/i/status/1921888766165168518","discovered_at":"2026-09-19T01:15:50.554Z","published_at":"Mon May 12 11:22:43 +0000 2025","topic":"history of science discovery lecture","transcript":[],"chapters":[],"score":1,"quality_reasons":["Educational format","Substantive source description","Established academic source","Accessible talk format"],"title_en":"RIP Tipu Zahed Aziz (1956-2024) Professor of Neurosurgery at Oxford University (UK).

We are adept at managing the tangible assets of the present, but lack the institutions to steward the intangible, contested and fragile domain of possibilities that constitute our collective future - the “future commons.”\n\nIn her inaugural lecture, Professor Juliane Reinecke reflects on her journey as a scholar of business sustainability, collective action, temporality, and commons governance.

He was pressing a reluctant guard to toughen up. This was before the experiment most people think they know had really gotten going.\n\nHere is the gap that recording opens up. The story almost everyone has absorbed is that if you put ordinary, decent people in a role and a system, they turn cruel on their own. But when a researcher went back into the study’s own files, that is not quite what he found. The guards did not simply snap. They were told how to behave.\n\nWe are not psychologists, and what follows is our reading of a long-running dispute in social psychology, not a verdict on it. The evidence here comes from old files and involves interpretation, and specialists still disagree about what it means.\n\nThe story almost everyone knows\n\nThe experiment ran in August 1971. Zimbardo, a Stanford psychologist, took 24 screened college-age men and randomly assigned them to be guards or prisoners in a mock prison built in the basement of the psychology building. It was planned for two weeks and halted after six days as the guards’ treatment of the prisoners got worse and worse.\n\nFor decades the takeaway was tidy and dramatic. Zimbardo said the study showed the power of the situation. Years later, he described it to Stanford Magazine as “really meant to be a single, dramatic demonstration of the power of the situation on human behavior.” The idea traveled far beyond the basement, into textbooks, a feature film, and Zimbardo’s 2007 book and later TED talk, where he linked it to the abuses at Abu Ghraib.\n\nIt is a compelling story partly because it is frightening. It tells you the line between a normal person and a cruel one is thinner than you would like, and that circumstance does most of the pushing. Zimbardo has long said the guards behaved in a way that “neither they nor we could have imagined.” That last claim is where the archive starts to complicate things.\n\nWhat turned up in the files\n\nIn the mid-2010s, French researcher Thibault Le Texier planned to make a documentary about the experiment. Digging into the study’s records at Stanford pulled him somewhere else. His 2019 article in American Psychologist, “Debunking the Stanford Prison Experiment,” drew on documents, unreleased recordings, and interviews with 15 of the original participants.\n\nHis argument was blunt: the guards did not change on their own. They were coached.\n\nThe most-cited piece of that coaching is the Jaffe recording. In it, the warden tells guard John Mark, in plain words, that “the guards have to know that every guard is going to be what we call a ‘tough guard.'” That is not a role emerging on its own. That is an instruction, given before the situation had done anything.\n\nA team of social psychologists led by S. Alexander Haslam later studied the same recording and put it this way: “We can no longer airbrush out the role of the experimenters in producing brutality.” Their analysis was a proposed reinterpretation, shared before peer review, and the authors themselves concede that saying this coaching alone caused the cruelty would go too far. It is strong evidence that the experimenters shaped the behavior. It is not proof the whole study was staged theater.\n\nThe guards who refused, and the one who admitted he was acting\n\nIf cruelty were the automatic product of the role, you would expect all the guards to behave the same way. They did not.\n\nJohn Mark, the guard Jaffe was leaning on, never bought the framing. Decades later he told Stanford Magazine, “I don’t think the actual events match up with the bold headline. I never did, and I haven’t changed my opinion.”\n\nThen there is the guard who did lean in. Dave Eshelman, known during the study as “John Wayne,” was its most abusive figure. He was a drama student at the time, and he described his conduct not as a personality overtaken by circumstance but as a performance. “I set out with a definite plan in mind, to try to force the action, force something to happen, so that the researchers would have something to work with,” he told the same magazine. “So I consciously created this persona.”\n\nThese are self-reports, given long after the fact, and memory bends over forty years. But they point the same way. One guard resisted the coaching and stayed skeptical. The most notorious one says he was playing a part he thought the researchers wanted. Neither reads like a mind slowly captured by a role.\n\nHow we’ve come to read it\n\nNone of this means situations don’t shape behavior.\n\nBut a partial replication run for the BBC in 2002 is telling here: without encouragement from the top to be harsh, the guards did not all turn cruel. That is arguably the more interesting finding, because it points to a specific source of pressure rather than treating cruelty as a switch that flips on its own.\n\nTo be fair, Zimbardo pushed back hard against Le Texier and the other critics, defending the study’s core lesson and arguing that coaching does not invalidate it. The disagreement is real, and we are not in a position to settle it.\n\nWhat stays with us is smaller and more practical. A vivid story, told well by a confident narrator, can go all the way into lecture halls and TED stages, before anyone opens the boxes it came from.\n\nThe archive was there the whole time. It took someone planning a documentary to actually look inside.\n\nhttps://t.co/wSbjJH8XMG","author":"Twitter for iPhone","url":"https://scienceblog.com/m-we-tend-to-think-the-stanford-prison-experiment-proved-good-people-turn-cruel-under-the-right-conditions-but-a-2019-archival-investigation-found-the-guards-had-been-told-exactly-ho","video_id":null,"domain":"Interdisciplinary","depth":"Intermediate","duration_seconds":null,"source":"twitterapimcp","source_url":"https://x.com/i/status/2090426124287258637","discovered_at":"2026-09-17T02:07:05.151Z","published_at":"Thu Aug 20 13:10:00 +0000 2026","topic":"ted talk 2007","transcript":[],"chapters":[],"score":1,"quality_reasons":["Educational format","Substantive source description","Established academic source","Accessible talk format"],"title_en":"We tend to think the Stanford Prison Experiment proved good people turn cruel under the right conditions, but a 2019 archival investigation found the guards had been told exactly how tough to act before the study even began | ScienceBlog","description_en":"We tend to think the Stanford Prison Experiment proved good people turn cruel under the right conditions, but a 2019 archival investigation found the guards had been told exactly how tough to act before the study even began | ScienceBlog","lang":"en","translated_at":"2026-09-17T02:07:08.666Z"},{"id":"bc23153a7908cc643178","title":"Peter Thiel is building a secret society of America’s top military, political & business elite","description":"Peter Thiel is building a secret society of America’s top military, political & business elite\n\nA data leak has exposed Peter Thiel’s invitation-only “Dialog” network, co-founded in 2006 and kept secret for nearly 20 years.

Image distance demo:\nYou are given a 3 second countdown before seeing a quick sequence of two pictures of the same object, divided briefly by a visual mask. The challenge is to identify whether the second picture is the same view as the first, or whether it's moved closer or further away. Try it yourself http://www.youtube.com/watch?v=gdzmNwTLakg&t=6m56s\n\n2. Drawing from memory demo:\nYou have 15 seconds to look at a picture, which you'll then be asked to draw, as accurately as possible, from memory. Try it now http://www.youtube.com/watch?v=gdzmNwTLakg&t=35m20s\n\n\nOur memories are our lives, and a fundamental basis of our culture. Collective memoirs of the past both bind society together and shape our potential future. With our brains we can travel through time and space, calling to mind places of significance, evoking images and emotions of past experiences. It's no wonder, then, that we so desperately fear the prospect of memory loss.\n\nMany regions of the brain are involved in memory, but one of the most critical components is the hippocampus, which plays a crucial role in the formation of long-term memories. Damage to the hippocampus can therefore result in significant memory loss.\n\nIn this Friday Evening Discourse, Eleanor Maguire draws on evidence from virtual reality, brain imaging and studies of amnesia to show that the consequences of hippocampal damage are even more far-reaching than suspected, robbing us of our past, our imagination and altering our perception of the world.\n\nMaguire also explains how, despite our beliefs, our memories are not actually as accurate as you might think.

Through in-depth interviews, the researchers found that as AI takes over tasks traditionally performed by junior developers, it also reduces opportunities for the hands-on experience and trial and error needed to develop into skilled professionals.\n\nThe paper presenting the findings, \"Who Will Become the Next Senior? How Generative AI Erodes the Development Pathway in Software Engineering,\" has been accepted to the 2026 AAAI/ACM Conference on AI, Ethics, and Society (AIES 2026), an international conference addressing the ethical and societal impacts of AI. The research is published on the arXiv preprint server.\n\nProductivity gains, training losses\n\nGenerative AI is increasing productivity across the software industry by rapidly performing repetitive development tasks such as coding, debugging and documentation. However, the new study raises a question that has received relatively little attention amid the focus on productivity gains: \"If AI takes over junior developers' work, where will the senior developers of the future come from?\"\n\nHiring of entry-level developers has recently declined both in Korea and abroad. According to data cited in the paper, entry-level job postings at the 15 largest U.S. technology companies fell 25% from 2023 to 2024. IT job postings in Korea declined 43% over the same period, while positions targeting entry-level candidates accounted for just 4.4% of all job postings.\n\nHowever, it is difficult to attribute these declines solely to generative AI, as multiple factors—including post-pandemic workforce adjustments and the economic slowdown—have also played a role.\n\nRather than identifying the causes of declining recruitment, the study examined how the roles of junior developers and the process through which they develop professional expertise are changing following the widespread adoption of generative AI. While previous discussions have largely focused on \"AI replacing jobs,\" the researchers focused on the fact that the tasks being taken over by AI are not merely repetitive work but have historically been part of the process through which developers build expertise by making mistakes and learning through trial and error.\n\nThe researchers examined Korea as a case in which these changes are appearing in a relatively early and visible form: AI is involved in 51.8% of work-related activities there, nearly twice the U.S. figure, while conventional entry-level hiring has contracted sharply.\n\nHow the study approached Korea\n\nThe research team conducted semi-structured interviews lasting approximately 50 minutes per participant with six senior developers currently working in the industry and eight junior participants preparing to enter software development careers. The senior participants were developers with at least six years of professional experience who had entered the workforce before the emergence of generative AI and remained employed, while the junior participants were undergraduates whose university years spanned the periods before and after the emergence of generative AI.\n\nThe researchers analyzed the interviews using reflexive thematic analysis and identified four major themes.\n\nWhen junior tasks vanish\n\nThe first theme was the shift of junior-level work toward a \"senior + AI\" workflow. Senior developers were increasingly using AI to directly handle tasks such as basic implementation, debugging and documentation that had previously been assigned to junior developers, reducing opportunities for juniors to gain hands-on experience in the process.\n\nOne startup founder interviewed for the study said the company had substantially reduced its junior workforce without any measurable impact on productivity, asking, \"What makes a junior developer better than a KRW 100,000-per-month AI subscription?\"\n\nFailure as a learning tool\n\nThe second theme was that what disappeared was not simply \"work\" but the \"opportunity to fail.\" The researchers describe this through the concept of \"productive struggle.\" When learners make mistakes and correct them themselves, they develop not only knowledge but also the ability to recognize what they do not know and identify errors in the results they produce.\n\nJunior participants said they could now achieve good results with less effort than before but also described the difficulty of \"not knowing what I don't know.\"\n\nOne participant who took two courses in the same field received the same grade in both yet said one course left them with actual knowledge while the other left them only with \"the ability to use AI.\" The only difference was whether the assignments could be completed using AI.\n\nThe researchers found that current educational assessment methods do not adequately capture this distinction. Senior developers raised the same concern. One participant said, \"The reason you become a senior is that experience teaches you what not to do. Now juniors can no longer learn from bad examples.\"\n\nPressure to use AI anyway\n\nThe third theme was that these changes are not simply the result of individual choices but of structural pressure. When all of a student's peers use generative AI, grading on a curve effectively becomes a mechanism that compels AI use. In the courses interview participants took, AI use was rarely restricted, so the loss of failure-based learning was structurally built into university classrooms as well as workplaces.\n\nA blind spot between generations\n\nThe fourth theme was that the problem does not correct itself because senior and junior developers perceive the same situation differently. Senior developers generally viewed the current changes as manageable because their years of practical experience enabled them to judge whether AI-generated results were correct or incorrect. Juniors, however, were losing precisely the opportunities for hands-on work and failure needed to develop those judgment criteria.\n\nOne senior participant said, \"We have 20 years of accumulated experience, so we can judge whether AI outputs are right or wrong. The next generation will not be able to reach that position. So we are fine.\"\n\nThe research team explains this phenomenon through the theory of \"situated cognition.\" The problems people can perceive differ depending on the positions they occupy: Senior developers and organizations with the power to address the issue may find it difficult to fully appreciate the circumstances facing juniors, while juniors who directly experience the problem lack the power to change educational and hiring structures.\n\nThe researchers also found that the problem did not originate with generative AI alone. Senior developers themselves largely built expertise through hands-on work and trial and error rather than through formal training systems. In this sense, generative AI has not eliminated a newly created development pathway; rather, it has accelerated the erosion of a pathway that had not been institutionally protected in the first place.\n\nBorrowing from future expertise\n\nThe study provides evidence that the development pathway for software developers, which may be weakened by generative AI, should be institutionally protected rather than left to individual effort. Other high-risk fields already provide examples of institutional measures designed to compensate for the effects of automation on skill development.\n\nIn aviation, pilots are advised to maintain opportunities for manual flying so that automation does not erode their manual flying skills (FAA SAFO 13002), while the nuclear industry requires regular simulator retraining to maintain operators' response capabilities. These are examples of deliberately preserving experiences necessary for developing and maintaining expertise even when automation can perform the underlying tasks.\n\nThe research team proposed that similar improvements are needed in software engineering across three areas: universities, hiring and companies.\n\nAt universities, the researchers argue that courses in which AI cannot achieve the learning objectives on behalf of students should be designated as required courses and that \"reducing AI dependence\" should be used as a criterion for evaluating educational quality.\n\nIn hiring, they propose evaluating not only candidates' ability to use AI to produce results quickly but also their ability to recognize gaps in their own knowledge and detect errors while working with AI.\n\nWithin companies, the researchers explain that learning opportunities should be deliberately created for entry-level developers—for example, by assigning them small modifications to actual products and allowing them to directly experience the entire process from commits and code review through deployment.\n\nMoon, who supervised the research, said, \"Some of the productivity we are gaining today may effectively be borrowed in advance from the expertise of the next generation. Because the cost is borne by a different group and at a different point in time from those making the decisions, it is structurally difficult to recognize. This study is significant because it empirically reveals that blind spot.\"\n\nHe added, \"Precisely because we are a department that develops AI technologies ourselves, I believe we have an even greater responsibility to ask what those technologies are doing to the development of the next generation. We plan to continue follow-up research focused on university education and to incorporate these findings into discussion","author":"Twitter for iPhone","url":"https://techxplore.com/news/2026-09-ai-junior-coding-tasks-weaken.html","video_id":null,"domain":"Interdisciplinary","depth":"Intermediate","duration_seconds":null,"source":"twitterapimcp","source_url":"https://x.com/i/status/2098403767049720274","discovered_at":"2026-09-14T11:25:22.449Z","published_at":"Fri Sep 11 13:30:19 +0000 2026","topic":"university of hong kong lecture course","transcript":[],"chapters":[],"score":1,"quality_reasons":["Educational format","Substantive source description","Established academic source","Subject relevance","Accessible talk format"],"title_en":"AI may cut junior coding tasks and weaken the pipeline to senior developers | Seoul National University, Tech Xplore","description_en":"AI may cut junior coding tasks and weaken the pipeline to senior developers | Seoul National University, Tech Xplore\n\nNew research suggests that generative artificial intelligence (AI) could weaken not only employment opportunities for junior software developers but also the pathway through which they develop into senior professionals.\n\nA research team led by Professor Taesup Moon of the Department of Electrical and Computer Engineering at Seoul National University College of Engineering investigated how generative AI is reshaping software developers' career pathways.
