How Do Superconductors Work?

In the reader request thread, Brad asks about superconductors: Why is a room temperature superconductor so hard? Why do things have to be cold for there to be no resistance (I can guess, but my knowledge of super conductors consists of the words “Cooper pairs” which does not get me very far.) Since next year […]

Reader Request: Quantum Complexity

There’s some good stuff in yesterday’s post asking what physics you’d like to read more about. I’m nursing a sore neck and shoulder, so I’ll only do one or two quick ones today, starting with James D. Miller in the first comment: 1) Is it true that our understanding of quantum physics comes from studying […]
