#79 – Lee Smolin: Quantum Gravity and Einstein’s Unfinished Revolution

Lee Smolin is a theoretical physicist, co-inventor of loop quantum
gravity, and a contributor of many interesting ideas to cosmology,
quantum field theory, the foundations of quantum mechanics,
theoretical biology, and the philosophy of science. He is the
author of several books including one that critiques the state of
physics and string theory called The Trouble with Physics, and his
latest book, Einstein's Unfinished Revolution: The Search for What
Lies Beyond the Quantum. EPISODE LINKS: Books mentioned: -
