I first heard about Occam’s razor (or Ockham’s razor) on the show Numbers. Since then, I have been interested in the theory. It is the principle that “entities must not be multiplied beyond necessity” (entia non sunt multiplicanda praeter necessitatem). The popular interpretation of this principle is that the simplest explanation is usually the correct one. Simplest is not defined by the time or number of words it takes to express the theory; “[simplest] is really referring to the theory with the fewest new assumptions.
