Schrödinger's Paradox

Where's Schrödinger's cat? Oh wait, it's not here.

Where is he? Not Where You Think
Note: Schrödinger's Paradox is a thought experiment in quantum mechanics that suggests a cat can be both dead and alive at the same time, depending on the observer. The cat in question is often imagined to be in a sealed box with a radioactive atom, which will randomly decay or not, and if it decays, the cat dies. The cat's fate is uncertain until observed. The subpages linked here are humorous takes on this concept.
