Books to build "physical intuition" All physicists say that it is very important to have this thing called physical intuition. I have a general idea what it means but I don't quite fully get the subtleties between physical intuition about a topic in physics versus understanding the equations, where they came from and how to apply them to a physical scenario. I seek this deep physical intuition that transcends mathematics and that physicists say is such an essential tool for great research. What in your opinion are some good books that can give one a physicist's intuition about topics, and in particular, intuition about higher level topics like upper division undergrad / graduate level electrodynamics, quantum and classical mechanics and field theory, statistical mechanics, etc... ? Please help me out!
