Since I've already covered some basic Magickal Theory, it looks like time to start on the Physics end of things. I'll start with the theories of Probability and Uncertainty. While this may be an interesting concept, Voltaire's logic is slightly flawed. Thus, the Theory of Probability is quite simple. Everything we see or experience is due to probability.
Uncertainty comes into play when there IS no one most probable thing to happen.
Good examples of uncertainty in action are small things, like electrons in orbit around an atom. Since there is no one most probable spot for that electron to be, it isn't in one place. There is a locus of higher probability, where in a lower energy electron is more likely to be closer to the nucleus, and higher energy ones farther away. Thus, scientists may either pin down where an electron is, or, where it is going, but, they CAN'T pin down both at the same time. Also, electrons tend to vibrate in energy level, spontaneously bouncing up and down, seeking their most probable states.
