    If everything is random how can we have laws?

    Yes, to high accuracy. Although very soon the processing power required becomes the limiting factor.

    If everything is random how can we have laws?

    No. Random doesn't mean particles can defy the laws of physics. It just means that, on some level, we can't predict the exact values of a tied pair of variables ( such as momentum and position) within a certainty of plank's constant. So any given particle has a wavelength. And we can't predict...

    If everything is random how can we have laws?

    Quantum mechanics isn't exactly random. There are probabilities, and certain events have a much higher probability. When you multiply that high probability among largescale systems (keep in mind, one inch is around 1033 plank lengths. So if you have a probability of 1/10 of something wierd...
