Do you believe in classical physics or quantam physics, why?
It is risky using a word like “believe” in a forum like AB. I don’t “believe” in anything in science. I find that quantum physics provides the best explanation we have so far found of behaviour at the small scale, and is therefore is the closest approximation to “truth” that we have yet found. Many thinks we use routinely (e.g. computers, mobile phones) are deeply based on predictions from quantum physics, so I cannot say that quantum physics is wrong. On the other hand, I can say that it is incomplete. At the other end of the scale, relativistic physics (I am not sure whether you call that classical or not) makes some equally accurate but unintitive predictions. But relativity and quantum mechanics are deeply contradictory. So some kind of deeper theory needs to be found which combines the two. It is like the parable of the blind men and the elephant: http://en.wikipedia.org/wiki/Blind_Men_and_an_Elephant . Both descriptions are partial desriptions, and true as far as they go, but not
