A roll of whose dice?
Is the universe deterministic, or random? Not the first question you'd expect to hear in a thriller, even a great one. But to hear this question posed soon after the opening sequence of "Knowing" gave me a particular thrill. Nicolas Cage plays Koestler, a professor of astrophysics at MIT, and as he toys with a model of the solar system, he asks that question of his students. Deterministic means that if you have a complete understanding of the laws of physics, you can predict with certainty everything that will happen after (for example) the universe is created in the Big Bang.
