According to what I learned in physics, magnetism is, quite literally, just electricity plus relativistic effects - that is pretty cool. Less cool is the idea that electromagnetism and weak nuclear force are "really the same, kind of, at very high energies". It must be known because it's true, but it doesn't make them "the same force" as some say.
