Schroedinger's Cat:
the quintessential quantum quandary

Which cat will appear? Move the mouse over this image to see...

Kids! Collapsing wave functions can be dangerous!

It's little wonder that Erwin Schroedinger chose a cat, that paragon of capriciousness and utter unpredictability, for his famous quantum physics thought experiment. Schroedinger's cat has come to symbolize the debates raging within quantum mechanics.

Schroedinger's cat can be represented mathematically; indeed, it arose because of the probabilistic nature of the Schroedinger model of the atom.
