Schrödinger's Cat is an hypothetical experiment designed to show a Quantum Paradox, in which a cat is placed inside a sealed box. A Geiger counter is placed nearby, along with a piece of radioactive material. By basing the cat's life or death status upon the probability of one nucleus, or none decaying in a period of one hour, the cat is said to be in a "Quantum Superposition of States" (i.e; both alive and dead at the same time because of lack of measurement.) This is analogous to the theory that an electron can be in more that one state at once i.e. rotating anti-clockwise or clockwise, purely because, that to confirm which direction it is spinning, it must be directly observed, and that very observation alters the rotation of that electron. The idea is reflected in the cards effect of "changing the result" of a draw.
