Thread: What are your favourite simple things that science just cannot explain?

electrons aren't just little magnets (well they are but...) its their angular momentum that plays the biggest role in macro scale magnetization. I don't know what we are even arguing though... photons do transmit electromagnetic forces, but I really don't see how that is any more of an "explanation" of magnetism than "the angular momentum of electrons" or "intrinsic magnetic moment". It seems to me that the concept of spin is more fundamental to any explanation of magnetism than the force carriers.
