Schrodinger’s Cow.
In Schrodinger’s famous thought experiment, a cow is placed in a large box containing a threshing machine that is controlled by a decaying potato atom. At any moment if the atom decays the thresher will be turned on and the cow transformed into meat. Since the decay of the atom is governed only by probability and it is impossible for an observer outside the box to tell if this has occurred - the cow exists both as an animal and a heap of delicious meat simultaneously. This led Einstein to remark that quantum meat effects were revolting to science. And he spent the rest of his life as a staunch vegetarian, attempting unsuccessfully to prove that meat obeyed the laws of classical physics.
