IIT Madras professor S. Lakshmi Bala walks a full quantum mechanics class through the two-level atom, and she does it for free. Western physics departments charge over $2,000 per credit for a graduate course in quantum mechanics. This entire course has been free since the early 2000s, but someone is trying to hide it. In this lecture she has already moved past abstract vector spaces into a real physical system, the same two-level atom model that shows up later in laser physics and quantum computing. No login wall. No certificate fee to just watch. One professor, one blackboard, one camera that never stopped rolling for over 40 lectures. Physics departments built million dollar tuition systems around gatekeeping exactly this material. IIT Madras just recorded it and gave it away through NPTEL, a program that now hosts over 3,200 free courses. ▪ $0 to watch, no account required ▪ Filmed lecture hall style since the early 2000s ▪ Same physics that underlies quantum computing today 🔖Just don't lose it and find a way to save the lecture, because other paid institutions don't want you to have access to it for free.

🔱Professor S. Lakshmi Bala of IIT Madras has published a free course on quantum mechanics, studying the three-level atom. MIT charges $80,000 to sit in a room and learn this. She didn't ask for a dollar. IIT Madras has a sub-1% acceptance rate. The students in that lecture hall competed harder to get in than most Ivy League applicants. You can watch the same lectures without applying anywhere. The course covers linear vector spaces, quantum state formalism, and the three-level atom - the math behind lasers, MRI machines, and quantum computers. Not a simplified intro. The real thing, from first principles. NPTEL built this. 7 Indian Institutes of Technology and IISc pooled their top professors and filmed the actual university curriculum. Thousands of courses. All free. Almost no one outside India knows it exists. Physics departments in the US have known for years that this content is available at no cost. They keep charging $80,000 anyway. 🔖Watch and save it before someone decides free access to elite education is a threat to the business model.

An Indian institute filmed a professor teaching classical physics with no notes, no slides, and a green board. Almost nobody outside India watches it. This is Classical Physics, lecture 1, taught by V. Balakrishnan at IIT Madras, published free by NPTEL, India's national open courseware programme. Balakrishnan taught at IIT Madras for decades. Students who sat in that room describe the same thing: the whole subject held in his head, delivered in order, no paper on the podium. Lecture 1 is the introduction. What classical mechanics claims, where the claims hold, and the exact points where they stop holding and quantum takes over. Watch how he speaks. Complete sentences, no filler, each idea finished before the next begins. Rare in any lecture hall on any continent. A physicist I know worked through the whole NPTEL series and rates it above the western courses he paid for. Free on YouTube, 17 years online, low resolution, no marketing. The teaching was never concentrated in the famous universities.

There's a physics lecture with over a million views' worth of value and almost no views. No slides. No notes. Just a green chalkboard and a man who clearly doesn't need one. The professor is V. Balakrishnan, IIT Madras. The course is Classical Physics, recorded for NPTEL — India's free national lecture archive — and quietly sitting on YouTube since 2009. What makes lecture one worth your time isn't production value. It's the opposite. It's a full subject held in one person's head, delivered in order, with nothing between him and the material. He opens with the actual boundary of the field: what classical mechanics can explain, and the precise point where it hands off to quantum theory. No hedging, no filler — every sentence finished before the next one starts. A friend who works in physics told me he went through the entire series and ranks it above courses he paid thousands of dollars for. It's been online for 17 years. Low resolution, zero marketing, still one of the best physics courses on the internet. Sometimes the best teaching in the world was never behind a paywall — it just wasn't in English-language algorithms' way of finding it.

MIT filmed a full graduate-level quantum mechanics course and put every lecture online for free. The instructor is Allan Adams. He stands in front of a chalkboard in a white shirt and opens by defining what linearity means before touching any physics. No slides. No animations. A man, a board, and a room of students working through the hardest framework in science. MIT OpenCourseWare started this in 2001. Faculty were told there would be no royalties and no extra pay for filming. Adams builds the course from the ground up. He treats quantum mechanics as a framework first and the strange results as consequences, not tricks. The catalog now holds more than 2,400 courses. The lectures have been watched hundreds of millions of times by people who will never set foot in Cambridge. Someone in a village with a phone gets the same lecture a student paying 60,000 dollars a year gets. The tuition was never buying the lecture.

MIT put its full quantum physics course online for free and the opening lecture starts with a box you can't look inside. Almost nobody finishes it. This is 8.04, Quantum Physics I, taught by Allan Adams on the MIT campus. Same room, same problem sets, same professor the tuition pays for. He skips the history and the philosophy. He builds a simple apparatus, sends things through it, and shows the result no classical picture can survive. Skip the first 10 minutes, that part is course admin. What follows is thought experiment stacked on thought experiment until superposition stops being a word and becomes the only explanation left. Every engineer arguing about quantum computing in 2026 is arguing about what happens in this hour. A systems engineer I know watched it twice with a notebook and called it the clearest teaching he'd seen since university. MIT charges $60,000 a year. This lecture costs nothing. The gate was never locked. Almost nobody walks through.

Why quantum theory could have a fractal structure: explained in 83 minutes. The notion of true quantum nonlocality is absurd. In the latest episode of the Quantum Foundations Podcast, Prof Tim Palmer from the University of Oxford suggests that there is a hidden assumption in standard quantum mechanics, and dropping it will save us from this absurdity. Namely, the reality of counterfactuals: the physics of what could have happened but did not. Inspired by chaos theory and the fractal structure widespread in atmospheric physics, Palmer has developed a new underlying structure for quantum theory, with radical implications for our fundamental principles of quantum physics; the limits of quantum computation; and perhaps even the search for quantum gravity. Watch on my YouTube channel, or listen on Spotify and Apple Podcasts!

How IIT Madras is Changing Global Security The End of Hacking? IIT Madras is spearheading India's push into quantum-secure communications through the IITM-C-DOT Samgnya Technologies Foundation, launched as the National Hub for Quantum Communication under the National Quantum Mission. This initiative aims to make communications "unhackable" by shifting from math-based encryption to physics-based security, countering future quantum computer threats. ​ The hub, inaugurated in December 2025 at IIT Madras Research Park, partners with C-DOT and is funded by the Department of Science and Technology (DST). It focuses on developing indigenous quantum hardware, QKD networks, quantum repeaters, and satellite-based systems to protect critical infrastructure like AI data centers and defense networks. Traditional encryption relies on complex math that quantum computers will crack in years. QKD uses quantum physics: any eavesdropping alters the quantum state, alerting the system instantly and burning the key. IIT Madras claims an edge in secure transmission over computing leaders like the US and China. ​ The hub builds real-world testbeds, subsidizes hardware for startups, trains experts, and links globally via IITM Global outposts. It positions India to lead in quantum-secure networks for sovereign AI and government use within five years. ​ IIT Madras also runs CyStar, a cybersecurity center advancing quantum security, AI model protection, and IoT defenses since 2024. This aligns with national goals for unhackable comms amid rising cyber threats. Credit : AIM Network.

The only physicist ever to win the Fields Medal taught a full Princeton course in 2022. The recordings have almost no views. Edward Witten works at the Institute for Advanced Study. He reshaped string theory and large parts of pure geometry, and mathematicians gave him their highest prize for it. This is Physics 539, Topics in High Energy Physics, autumn 2022. Full semester, lecture by lecture, chalk on a board, graduate students in the room. No lecture notes released. No production. No description on the videos. Someone sat in the back row and hit record. Watch how little he writes. A few symbols, 1 small diagram, and the whole argument carried in speech while the board stays nearly empty. A theoretical physicist I know worked through the playlist over a summer and said it read like watching someone think in real time. Free on YouTube, uploaded by an attendee, no institution behind it. Universities publish the public talks. Somebody filmed the real course.

What if physics is just the universe learning? Most Theories of Everything episodes are mind‑bending for their math, physics, philosophy, or consciousness implications. This one hits all four simultaneously. Professor Vitaly Vanchurin joins me to argue the cosmos isn't just modeled by neural networks—it literally is one. Learning dynamics aren't a metaphor for physics; they are the physics. Vanchurin shows why we need a three‑way unification: quantum mechanics, general relativity, and observers.

Most people pay $50,000 for an MBA to learn what Chamath just taught Stanford students for free in one session. No tuition, no application, no waitlist, just Chamath Palihapitiya sitting in a Stanford lecture hall telling students exactly how to win in the AI era. The man who backed Facebook at $500M valuation and built a $1.5B fund just gave away his playbook for free. Watch it, bookmark it, send it to someone who needs it.

Biden Appointee Claims Non-Binary People Understand Quantum Mechanics Better At Socialism 2025, Chanda Prescod-Weinstein—a physics professor at the University of New Hampshire and Biden appointee to the Department of Energy’s High Energy Physics Advisory Panel, which helps shape federal science funding—offered a unique take on quantum mechanics: “There are good arguments for why, for example, non-binary people find wave-particle duality very straightforward. Yes, you can be both at the same time.” She went on to frame science as a domain for “freedom dreamers” and warned against ceding the field to those “who are like, yeah, I’ll go work for the military.” This is someone with real influence over which science gets funded in America—and who’s also shaping the next generation in the classroom.

Federico Faggin: "Quantum Fields are conscious & have free will" "You cannot create something that can know itself by something that doesn't even know what knowing means." The inventor of the first commercial microprocessor argues that consciousness cannot emerge from non-conscious matter. No mechanism can explain how awareness arises from something without any knowing. Instead, Faggin proposes quantum information-based panpsychism: quantum fields themselves are conscious and possess free will. These must be fundamental primitives of reality, not reducible to physics. This view explains the collapse of the wave function as a free will decision and why quantum mechanics describes what can be known rather than deterministic reality. Consciousness transcends energy, space, and time. Starting with it as basic unlocks meaning and resolves the hard problem that materialism cannot solve. A profound challenge to conventional science from one of computing's pioneers.

Marvin Minsky, MIT professor and father of AI: "The best trader on Wall Street is no longer human. I spent fifty years proving the mind is just a machine built from smaller machines, and once that's true, nothing stops a machine from being the house. it already is." this free lecture holds the entire "AI edge" the funds and the gurus sell, and the man teaching it founded the field itself and put his whole MIT course online for free. at the board it's simple. Minsky's idea is that there is no magic in thinking. a mind is a huge pile of small, mindless parts, each doing something simple, and intelligence is just what happens when enough of them work together. a trading machine is the same trick: thousands of simple rules stacked until an edge appears. that's the whole "AI", minus the mystery. Minsky taught this at MIT and published "The Society of Mind" in 1986. the course has been free ever since. same point as my casino piece above: the house wins with many small mindless advantages stacked, not with one born genius. the ideas are free and every AI lab and every fund already has them. what they cannot sell you is the data and the compute to actually build the machine. that is the real moat now, and no lecture can hand it to you.

MIT put its full multivariable calculus course online in 2007 and charged nobody a dollar for it. Lecture 34 is the final review. A professor in an orange sweater writes Unit 1 on a chalkboard and starts working through the whole semester. The camera never moves much. No editing, no music, no production budget visible anywhere. MIT OpenCourseWare launched in 2001 with 50 courses. The plan was to publish materials from every course the university taught. Faculty were told they would get no royalties and no extra pay. Most agreed anyway. The catalog passed 2,400 courses. Downloads run past 300,000,000 and the site draws millions of visitors a year from countries with no equivalent institution. Universities charging 60,000 dollars a year watched a peer give the lectures away and kept charging. The thing people pay for was never the lecture.

MICROSOFT BUILT THE COLDEST PLACE IN THE UNIVERSE TO UNLEASH A QUANTUM MONSTER Colder than interstellar space - 40x colder, actually - and no, it’s not a freezer. It’s a launchpad for Microsoft’s 1 million-qubit quantum chip, powered by a particle that wasn’t even proven to exist until now. While everyone else is bragging about 1,000-qubit machines the size of a warehouse, Microsoft just said: “Cool story. We put a supercomputer in our hand.” Their latest chip uses Majorana particles to do the impossible: cram football-field-level quantum power into something palm-sized. Normal computers crawl through problems one bit at a time. Quantum? It takes every path at once. And this thing? It’s got millions of paths. The quantum arms race just got very real. Source: Rillo TV

Prabha Sharma, one of the sharpest women mathematicians India has produced: "Optiver puts every applicant through a probability gauntlet, then pays the ones who pass $500,000 a year for one skill: counting the ways an outcome can happen before anyone else does. that is exactly where this professor opens her course, and it is free" this free lecture is the foundation under every prediction market and every price you have ever seen. strip away the models and the AI and one question is left. in how many ways can this happen, and how many of them pay you. get that count right and the probability falls out on its own. get it wrong and every model built on top is wrong with it. Sharma builds it from zero, on a blackboard, in notation a schoolkid can follow. permutations, combinations, the n choose r sitting under every set of odds. Wall Street rents this out as a $500,000 edge. an IIT professor hands you the whole foundation for free.
