Fun with Newton's 1st Law and discrepencies within it.

[lukevanoort]

Newton's Laws and all other classical physics type stuff (si=v*t, si+v*t+a*t^2=sf, etc) are all approximations that work pretty well in everyday life, at everyday speeds. Classical physics doesn't really work well at very small scales, or at very high speeds. This is where quantum physics comes in, and, in addition to explaining some odd things, it makes really REALLY strange predictions and is just generally weird. If you ever feel like not only confusing yourself for one class, but instead for several weeks, look in to quantum physics, in particular topics like vacuum fluctuations and quantum coupling.
