Metaphysics of Materialism
Content: The problem with Einstein's theory (there's always a problem!) was that it only worked at the big level; gravity and its effects on big things like planets and galaxies. However, it did not work at the subatomic level where electrons move in fairly strange ways. This arena of the universe was the province of quantum mechanics. This theory was the brainchild of, among others, Max Planck, Niels Bohr, and Werner Heisenberg. Heisenberg, in particular, is relevant for our original problem of determinism. His uncertainty principle implied that there was a limit to how much knowledge we could have at the subatomic level. Simply put the uncertainty principle says that our knowledge of one attribute comes at the expense of knowledge of another attribute. For example, say you want to know how fast an electron is traveling and you'd also like to know where it’s located.
