In 1935, Erwin Schrödinger proposed a thought experiment: a cat in a sealed box, both alive and dead until observed. The point was to expose what he saw as an absurdity in quantum mechanics. The thought experiment outlived the argument.

Major League Baseball's Automated Ball-Strike system creates a similar problem. A pitch exists as both a ball and a strike — held in superposition by the umpire's call — until the challenge is resolved.
