: 推 noonee:what's the key idea of this book? : 05/20 00:52 The key ideas of the book are: (1) As far as extending the knowledge of fundamental laws of Nature is concerned, we have made no real progress during the past 25 years. There is still something big missing in our framework of fundamental physics. For example, we have no idea of why neutrinos have mass or what explains their mass value. Also, we almost know nothing about dark energy. (2) Superstring Theory may not be the best candidate for TOE (theory of everything) in the author's opinion. It appears that the current research of superstring theory attracts too many bright young physicists & too much funding so that other alternatives to superstring theory have not yet widely explored & investigated. Plus, Superstring theory appears to have too many versions. It is extremely hard to prove experimentally which one is right. Smolin is worried about this trend. (3) Smolin mentions a few young (out of the big crowd) scientists who have the guts to have gradually developed alternative testable theories to explain some bizarre phenomena that our current physics framework can not explain. -- " An expert problem solver must be endowed with two incompatible qualities ─ a restless imagination and a patient pertinacity" --- Howard W.
