Quantum mechanics is more than a century old, but physicists still fight over what it means. Most of the hand wringing and knuckle cracking in their […]
Do We Need a Theory of Everything?
I get constantly asked if I could please comment on other people’s theories of everything. That could be Garrett Lisi’s E8 theory or Eric Weinstein’s geometric unity or Stephen Wolfram’s idea that the universe is but a big graph, and so on. Good, then. Let me tell you what I think about this. But I’m […]
