Intuition In Depth: Bridging Science and SpiritualityLet's warm up with this one. Do you know how radio works? I can't say I really do, but I know this. Signals from a radio broadcast, like any other electromagnetic signals, are waves that travel in the atmosphere. Somehow recording a radio show sets a series of electromagnetic waves in motion that radiate out into space. They can be picked up by radios in the viewing area tuned to waves of that frequency. So all of space is packed full with electromagnetic magnetic waves, some from Garrison Keillor, some from Adolph Hitler, and some from the Big Bang.

So much for the warm-up--- which is actually a bit of priming. Here comes the quantum physics. Our physical experience is dominated by objects that have more or less clear boundaries, that are separate from each other. Also causality reigns. If I so choose, with my arm I can knock the folder next to my computer off my desk. This follows the laws of classical physics.
But at the quantum level, the level of subatomic particles, most scientists think that it is all chance and randomness. Probabilities rather than certainty or causality are supposed to rule. It is only when an observation is made that the function that determine these probabilities, the wave function, collapses into specific state. Before that all possibilities are said to coexist or are superimposed.

Not everyone was happy with the randomness that the usual interpretation of quantum mechanics enshrines at the core of reality. Einstein famously said, "God does not play dice." He was not willing to give up the elegant determinism of classical physics. So he proposed that there must be hidden factors, what he called hidden variables, which really control events at the quantum level.
