Everything, even life, seems to be made of particles. Mathematically the state of these Particles cannot be described by six numbers. Their position and velocity, but by a wave function. Giving them properties both of particles. (They exist or they don't.) And in ways they can be in several Places at once in a so called super-position. This equation shows that in some microscopic super-position. Can't get in fighting to crazy, microscopic super-position. Like you, personally deciding to be in two places at once.
