Probability

Oh, it's very spooky. First of all, probability by itself is spooky. Give me... let me show you how probability enters the [system:company] . You walk past a store window and you see an image of yourself in the store window, you straighten the part, not so bad you know, for a man of my age. The guy in the store window who's fooling around with mannequins he sees you and you see yourself. What does that mean? A [stream:chain] of photons from sunlight leaves your face, heads for the store window - let's consider one of them. It has a choice: it can go right through, so that the guy behind the window can see you, or it can be reflected from the store window. Some [fractions:functions] of them are reflected, and some of them go through. What determines that? What determines the future of that photon? And [countless:numberless] such examples teach us that it's random, that it's a [throw:roll] of the dice, and that's where Einstein made his famous statement "God plays dice with the universe." That every instant of that single object, that quantum object we have probability, we do not have certainty.
