General relativity from first principles – Adam Brown - YouTube
Adam Brown breaks down the foundational insights of general relativity, explaining how Einstein navigated the tension between Newtonian gravity and the speed of light. Through accessible concepts like curved spacetime and the equivalence principle, the discussion explores why gravity functions as an emergent geometric phenomenon rather than a traditional force.
Adam Brown is back! General relativity is said to be the most beautiful idea the human mind has ever produced. Most of us will never get to fully appreciate its elegance by taking the 20-lecture graduate course Adam taught on it at Stanford. But in this episode, Adam distills the key idea at its heart so clearly and compellingly that even I could keep up lol. At the core of general relativity, Einstein is trying to figure out the principle behind a particular coincidence: that the mass that resists acceleration and the mass that gravity pulls on just happen to be exactly the same. Adam then…
