Our Mathematical Universe

This book by Max Tegmark came up once on Lex Fridman in the episodes we index. That mention was a genuine on-air recommendation, not just a passing reference. The people who brought it up: Lex Fridman. Every occurrence below links to the episode page and to the exact second it was said on YouTube.

"Max Tegmark leads us on an astonishing journey through past, present, and future, and through the physics, astronomy and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and ground-breaking science, he not only helps us grasp his often mind-boggling theories (his website gives a flavor of how they might boggle the mind), but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist.
