About This Design

Schrödinger's cat keychain

Schrödinger's cat keychain

Schrödinger's cat is a thought experiment. The thought experiment presents a cat that might be alive or dead, depending on an earlier random event and, until observed, the cat exists as both dead and alive simultaneously. The thought experiment illustrates the bizarreness of quantum mechanics and the mathematics necessary to describe quantum states.
