1:35:00ENLex Fridman· Dec 25, 2019Podcast · 2 speakersNASA Once Spent 5 Percent of the Economy to Go 250,000 Miles. Mars Is a Hundred Times Farther.Guest Jim Gates · Host Lex FridmanTheorist S. James Gates Jr. talks with Lex Fridman about Mars budgets, supersymmetry, error-correcting codes hiding in equations, and why string theory is not yet a theory.
