Description Schrödinger's Zombie Cat
A cat in a state of superposition, that is, alive and dead - both at the same time and yet somehow neither - can only be one thing. A zombie cat! And when is one in two states at the same time? When Schrödinger locks you in a room with an unstable atomic nucleus.
More about the equation and the poor cat can be found here.
