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.
The intro everyone's talking about (rightfully, so)!
Hear from Brandon, a projectionist at Cinemark Dallas XD and IMAX, as he gives his IMAX 70mm pre-film intro before The Odyssey 👏
The parallels were never meant to fit perfectly.
The Coens called the film only “very loosely” based on The Odyssey. Neither had read the entire poem!
Homer by way of bluegrass and hair pomade.
What a film.

In 1983 the BBC set a camera in Richard Feynman's living room. He talked for 66 minutes and wrote 0 equations.
The film is called "Fun to Imagine." Shot at his home in Altadena. 1 chair, 1 Nobel laureate, no script, no slides.
He describes fire as sunlight a tree trapped years before. Burning the log releases it back into the room.
He explains why a rubber band stretches. Why a mirror swaps left and right yet leaves up and down alone.
Then the interviewer asks how magnets work.
Feynman turns down the shortcut: "I can't explain that attraction in terms of anything else that's familiar to you."
That refusal carries the whole film. He teaches a way of seeing before he hands over a single fact.
Feynman died 5 years after the recording. The full version still circulates in HD.
66 minutes in an armchair. 43 years of people still watching.
Lamine Yamal on Lionel Messi after Spain’s FIFA World Cup triumph over Argentina.
🗣️ Lamine Yamal: “Tonight I lifted the World Cup for Spain, but I also experienced something I’ll tell my children one day. The man who once held me as a baby was standing on the other side of the pitch, fighting for the same dream. Football has a beautiful way of bringing stories full circle.”
“When I looked at Messi after the final whistle, I didn’t just see an opponent. I saw the player who made millions of kids, including me, believe football could be art. I saw the man whose videos I watched over and over, trying to copy things that nobody else could do.”
“I know this defeat will hurt him. You don’t play with that much passion, carry your country again and again, and lose a World Cup final without feeling pain. Even in defeat, he kept demanding the ball, creating chances and refusing to stop believing. That’s what champions do.”
“People will talk about Spain winning this World Cup, and they should. But they’ll also remember that, at an age when most legends have already retired, Messi was still making the world’s best defenders panic every time he touched the ball. That’s extraordinary.”
“The photo of Messi bathing me became one of football’s most iconic images. Today we took another picture together, but this time I could thank him face to face. Without players like him, kids like me wouldn’t dare dream this big.”
“One day another generation will replace mine too. That’s football. But there will never be another Lionel Messi. Records can be broken and trophies can be won, but inspiring an entire generation to fall in love with the game is something only a few people in history will ever achieve.”
“Tonight belongs to Spain. Tomorrow, the debates will continue. But my respect for Lionel Messi will never change. He didn’t need to win this final to prove who he is. For me, he’ll always be one of the greatest players football has ever seen, and sharing the pitch with him was a privilege I’ll carry for the rest of my life.”
Richard Feynman stood at a Cornell blackboard in 1964 and explained the problem every AI lab is fighting in 2026. The BBC filmed it. Almost nobody watches it.
The lecture is about why nature only answers in mathematics. Every team forcing language models to reason is hitting the wall he mapped 62 years ago.
He was 46. The Nobel Prize came 11 months later. The footage survived on film reels and now sits free on YouTube with fewer views than a keyboard unboxing.
Watch the blackboard section near the middle. He takes 1 of Kepler's laws and rebuilds it from nothing, with notation a 12-year-old can follow.
No slides. No jargon. 1 piece of chalk.
An ML engineer I know paused it 4 times and made his whole team watch it before standup.
You're 62 years late. The lecture is still free.
A great story narrated by novelist John Irving which got even better when I researched the context.
"A student of mine at Iowa—a brilliant fellow, academically; he would go on to earn a Ph.D. in something I can't even pronounce or spell—wrote an accomplished, lucid short story about a dinner party from the point of view of the hostess's fork.If you think this sounds fascinating, my case is already lost. Indeed, the young writer's fellow students worshiped this story and the young genius who wrote it; they regarded my all-too-apparent indifference to the fork story as an insult not only to the author but to all of them.
Ah, to almost all of them, for I was saved by a most unlikely and usually most silent member of the class. He was an Indian from Kerala, a devout Christian, and his accent and word order caused him to be treated dismissively—as someone who was struggling with English as a second language, although this was not the case.
English was his first language, and he spoke and wrote it very well; the unfamiliarity of his accent and the cadence, even of his written sentences, made the other students regard him lightly. Into the sea of approval that the fork story was receiving, and while my "but . . ." was repeatedly drowned out by the boisterous air of celebration in the class, the Indian Christian from Kerala said, "Excuse me, but perhaps I would have been moved if I were a fork. Unfortunately, I am merely a human being."
That day, and perhaps forever after, he should have been the teacher and I should have given my complete attention to him. He is not a writer these days, except on the faithful Christmas cards he sends from India, where he is a doctor.
Under the usual holiday greetings, and the annual photograph of his increasing family, he writes in a firm, readable hand: "Still merely a human being."On my Christmas cards to him, I write: "Not yet a fork."
And now for the kicker. After a little digging, I figured out that the student from Kerala in question was actually the physician and novelist Abraham Verghese who went on to write the amazing 'Cutting for Stone' in 2008, 12 years after this extract was first published.
