Adam Brown – Einstein's happiest thought: General Relativity from scratch
Summary
Dwarkesh Patel interviews physicist Adam Brown to explain the core insights of Einstein’s general relativity without advanced mathematics. Brown contrasts Newtonian gravity with relativity, highlighting the equivalence principle and how mass curves spacetime to create inertial forces. The discussion covers the historical development of the theory, the nature of black holes, and why gravity behaves differently from electromagnetism.
