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.
NPTEL is a genuinely underrated treasure, especially outside India. These recordings really should be watched by students all over the world, not just their own.
Both his kids are MIT professors as well - having graduated IIT Madras themselves
