Occam's Razor

Occam's razor (or Ockham's razor) is a principle from philosophy. Suppose there exist two explanations for an occurrence. In this case the simpler one is usually better. Another way of saying it is that the more assumptionsyou have to make, the more unlikely an explanation is. Occam's razor applies especially in the philosophy of science, but also more generally.
