🔱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.show more
