The Bohr model, Landau quantization, and “truth” in science

A few years ago, at a big physics conference, I was party to an argument about whether we should be teaching the Bohr model of the atom in lower-level physics classes. The argument in favor was that the Bohr model is easy to teach and gives a simple way to think about the structure of … Continue reading The Bohr model, Landau quantization, and “truth” in science
