My Favourite Technical Lectures

• The Feynman Lectures on Physics
  The one on thermodynamics blew my mind when I first read it in freshman year of college.
• Frederic Schuller's Lectures on Quantum Theory
  Wonderfully explains the rigorous math of quantum theory (think Hilbert spaces, functional analysis and measure theory). I was fascinated by the first lecture, when he says that quantum states are not elements of a Hilbert space but maps from a Hilbert space to itself (positive trace-class linear maps to be specific).

My Favourite Non-Technical Videos

• Cumrun Vafa on Lex Fridman Podcast
  Explains the thought experiment of why objects of different masses fall with the same acceleration under gravity. Imagine 2 bricks of the same mass a foot apart and drop them both, they fall at the same rate. Then bring them closer so they are half a foot apart and repeat; same outcome. In the limit as you bring them closer towards zero separation, the result stays the same, but you now have an object of twice the mass.
