A theoretical physics course opens not with equations but with the rules for saying anything true at all. This is lecture 1 of Lectures on the Geometric Anatomy of Theoretical Physics, taught by Frederic Schuller. The topic is propositional and predicate logic. Most physics courses assume logic and start...

Yes. People are starting to see that geometry is the solution. You know who we owe a fucking apology to? Tesla. Cause that babe was right and we have occuied an "advanced" civilization without actually knowing how the tools work. Einstein kept us trapped in a matrix and Tesla was fucking robbed and no one stood up for him and you have all turned ur nose to para whatever.

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.

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.

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.

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.

Nobody can track 10^23 particles. A professor in Chennai spends an hour explaining why that stopped being a problem 150 years ago. This is Classical Physics, lecture 20, from V. Balakrishnan's course at IIT Madras, on the founding postulates of equilibrium statistical mechanics. The move is a surrender that pays. Stop following trajectories. Count how many microscopic arrangements produce the same macroscopic state, and temperature, pressure, and entropy fall out as consequences. Every sampling method in machine learning is a descendant. Diffusion models, MCMC, Boltzmann distributions in softmax. All of it is state counting wearing different notation. Watch how he handles the postulates themselves. He states what is assumed rather than derived, then refuses to pretend the assumption is a proof. A machine learning engineer I know rewatched the first 25 minutes and said sampling stopped looking like a trick. Free on YouTube, low resolution, green chalkboard. The particles were never the point. The counting was.

A NASA fellow claims 5 equations explain 99 percent of the physics that actually runs your world. Understand them deeply and you are set for life. His words. And the way he does it is what makes the video worth it. He does not teach the five as a list. He tells them as one story, where each equation is born from the one before it. F equals ma leads into gravity. Gravity rhymes with the law of electric charge, the exact same shape. That connects to magnetism. Magnetism folds into the wave. And the wave quietly opens the door to relativity and quantum physics. By the end, all of physics feels like a single sentence written by one hand, not a pile of formulas you were forced to memorize. The move that stays with you comes first. He says F equals ma is written the wrong way around, and rewrites it. One tiny flip, and the most famous equation on Earth suddenly means something school never told you. His point for why this matters now: in the age of AI, the people who understand reality itself stay in demand. Everyone else is just memorizing. Five equations. One thread. It is in the video.

A physics professor ran a live demonstration on national television in 1964 and it went wrong on camera. He didn't cut away. He got happier. This is Julius Sumner Miller on the ABC program Why Is It So?, crushing a reinforced metal tank with atmospheric pressure. The experiment refuses to behave. Watch his face when it fails. No embarrassment, no apology to the audience, no reshoot. Failure was the interesting part and he wanted the camera on it. Every engineer who hides a broken demo, every team that only ships the run that worked, is doing the opposite of what this man did on live TV 62 years ago. The physics is simple: air pressure you can't feel, doing work you can't ignore. He makes it visible with a tank and a heat source. A hardware engineer I know sent this clip to his team after a failed launch demo with 1 line: this is how you handle it. Black and white, 1 camera, free on YouTube since 2018. He wasn't performing certainty. That's why it still plays.

Professor Jiang says the moon landing never happened and he thinks the giveaway is what came after. His case is not about flags or shadows. It is about what usually follows a major scientific breakthrough and what, in his view, did not follow Apollo. “Nothing came out of the moon landing revolution.” He compares it with the Manhattan Project: new physics, then a transformed civilian world. After the moon landings, he says, the telemetry was lost, the consumer payoff was thin, and theoretical physics did not move.

Here's my conversation with Don Lincoln about some of the biggest open questions in physics, including dark energy, dark matter, the matter-antimatter imbalance, quantum vacuum, quantum foam, and the quest to unify the laws of physics. Don is a particle physicist at Fermilab who has spent decades working at the frontiers of high energy physics. He is also a great teacher & writer. I highly recommend his courses & books. One of my favorite lecture series he has given is The Evidence for Modern Physics where he breaks down the experiments that validate some of the weird laws of physics we have, and what it would take to validate even the weirder ones. It's not enough to come up with a beautiful theory. You also have to show through experiment that the theory is likely to be correct. This process often doesn't get the love it deserves, even though it's often the most important and difficult part of the scientific process. I ❤️ physics. The conversation is here on X in full and is up everywhere else (see comment).

Eric Weinstein unleashes a bombshell: Theoretical physics froze in 1973—right as "Crocodile Rock" topped the charts—and hasn't advanced at the deepest level since. Youngest living Nobel in theoretical physics? Always under 50... until string theory took over as "quantum gravity." Now it's over 70. The field stopped producing breakthroughs. His wild claim: The Biden White House reportedly told Marc Andreessen they deliberately stagnated parts of theoretical physics—cocooning string theory as the "only game in town." Dissenting ideas? Career suicide. The trick? Hammer "quantum gravity is the holy grail" on repeat until it feels true. (Weirdly, that phrase barely appears in books before 1972.) Safe, harmless pursuit—no real risk even if foreign students dive in. Why? To avoid dangerous progress that could shatter the speed-of-light limit and get us to the stars... before humanity's tools become too lethal on one fragile planet. Weinstein's rallying cry: Physics is our only path off Earth. Break the stagnation, surpass Einstein, reach the cosmos. The end of physics as we know it might be glorious—if we seize this brief window before wars erupt. Clip from his ARC 2025 talk (4:05 of high-stakes provocation). Does this ring true—the deliberate stall on breakthrough physics? Or is string theory just a victim of its own complexity? What's your take on the "holy grail" mantra?

When you touch something warm, a Yale physicist can tell you exactly what you are feeling. Not heat. The speed of atoms hitting your hand. His name is Ramamurthy Shankar. You were taught that temperature means how hot something is. That is a description, not an answer. In this lecture he goes under the word and shows what temperature actually is, and it is not what any school ever told you. He builds it from nothing. A box of gas. Invisible atoms bouncing off the walls. He counts the hits, tracks the momentum, and slowly two sides of a chalkboard drift toward each other. When they finally meet, out falls one clean line that redefines a word you have used your whole life. The same lecture answers a question that should be impossible. How did anyone count the atoms in a gram of matter before anyone could prove atoms were real? The answer is so simple it feels like cheating, and it is why a single number, six followed by 23 zeros, sits at the center of chemistry. He assumes nothing. Every step is earned in front of you, no memorizing, no faith required. This is the lecture where hot and cold stop being feelings and become physics.

"The mathematics of string theory is probably one of the most beautiful artifacts humanity has created. In order to even produce something in theoretical physics, there's hundreds of years of literature that you need to catch up on, and also every day there's, 100 new papers that come out. And before you can contribute to theoretical physics, you need to know basically all of math, like algebraic topology, differential equations, algebraic geometry, and these are all things that people will spend their careers going in on, and yet to do the physics, you need to at least have, a pretty deep understanding of these things. And so it really teaches you how to have, good judgment with minimal information." Matan Grinberg studied physics for a decade, eventually dropping out of his PhD focused on string theory to found Factory.

An MIT professor fired a gun in a lecture hall to teach students one formula. The recording is online. The topic sounds boring on paper: velocity and acceleration. Then he pulls out a rifle. He wants the speed of a bullet. No modern sensors, just two wires and a timer. He makes the room do the math first, counts down from three and shoots. The number on the screen settles it. After that he brings up Sherlock Holmes. A scene where a man falls on a marble floor and Holmes announces the skull is crushed. The professor explains why that moment is flawless physics, and why a bald head made it worse. You will never watch that scene the same way. There are also eggs and a tomato. They do not survive. Same physics as the skull. One gunshot, one detective, one dead tomato. All in the video.

🔱IIT Madras professor V. Balakrishnan walks a full classical physics class through the foundations that connect Newton to quantum mechanics - he does it for free. US universities charge over $3,000 per credit to sit in a room and hear this material. Balakrishnan covers more ground in one semester than most Western physics programs fit into two years - and his first lecture alone reframes why classical mechanics matters at all. He opens not with equations but with a question most professors skip: why does classical physics still exist when quantum mechanics replaced it? The answer restructures everything. By the time the introduction ends, you are already inside the mathematical skeleton that connects Newton, Lagrange, Hamilton, and Feynman into one coherent picture. No paywalled syllabus. No overpriced textbook required. Just a blackboard, a professor who clearly spent decades thinking about how to teach this, and a playlist that runs 47 lectures deep. NPTEL filmed the actual university curriculum at 7 Indian Institutes of Technology and put all of it online. Over 3,200 courses, zero subscription. Western institutions have known about this for years and said nothing. ▪ Lagrangian and Hamiltonian mechanics from first principles ▪ Nonlinear dynamics and chaos theory included in the same course ▪ Graduate level, no prerequisites assumed beyond calculus 🔖 Bookmark before the algorithm buries it - this is the kind of content paid platforms charge hundreds of dollars to approximate.

Elon Musk on why physics is the only law you can't break "Physics is the law, and everything else is a recommendation. I've met a lot of people who can break the law, but I haven't met anyone who could break physics" "For any kind of technology problem, you have to make sure you're not violating physics. First-principles analysis can be applied to really any walk of life" "It's really just saying, let's boil something down to the most fundamental principles, the things we are most confident are true at a foundational level. That sets your axiomatic base, and then you reason up from there"

One of the men who invented the transistor stood at a Bell Labs blackboard and explained how it works. AT&T kept the film. Almost nobody watches it. Walter Brattain shared the 1956 Nobel Prize in physics for the transistor. Every chip training every model in 2026 descends from what he built with Bardeen and Shockley in 1947. This is 28 minutes of the inventor teaching semiconductor physics himself. Properties, simple model, history, impact, new phenomena, written on the board in his own hand. Watch the section where he draws the crystal lattice and shows what an electron and a hole actually do inside it. The abstraction most engineers carry around, drawn from scratch by the man who found it. An embedded engineer I know watched it twice and said 28 minutes of chalk beat a semester of textbook diagrams. Free on YouTube from the AT&T archives, 10 chapters, black and white. Everyone uses his invention. Almost nobody hears him explain it.

This is probably one of the easiest way to sell on Meta ads. Not because it sells the product, but because it never really tries to. Watch it and you will see what I mean. I am a hardcore direct-response marketer. I believe you show the product, show the demo, make people feel the thing. This ad does something different, and it still works on me. It opens with an old man in a turban (the visual does 70% of the selling). He looks like he has lived a hard life and is still standing strong. He has not said a word yet and you already trust him. That is the whole trick. The elder look earns respect before the pitch even starts, so you stop scrolling and drop your guard. Then the first line lands. In my village, women are still farming on their feet at 80. No joint pain, no pills. He is not selling a supplement. He is selling ancient wisdom. And the moment he says his grandparents never needed pills, the promise stops feeling like a sales claim and starts feeling like proven tradition. Tradition is harder to argue with than a product. That is the real lesson here. He made me feel the trust before he made a single claim. By the time the product shows up, I am already leaning in. If your ad can earn trust and make people feel something before you ask for anything, you have done the hard part. Next time you build a creative, do not open with the product. Open with the person and the feeling. Let people trust you before you sell them. Follow for more ad breakdowns and ideas like these.

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.
