Laws cannot be proven because of the fact that they implicitly claim universality (all systems of the defined type must be behave as the law describes) and thus can be falsified by any instance of a "misbehaving" system.

Laws are empirical, not necessarily universal. They are rules of thumb based upon observation. Ampere's law, for example, fails for circuits that contain capacitors. It is still called a law, however, because of how it was constructed, and it is still taught because it works well in its region of applicability.

Ampere's law is folly. Join with Ohm, leader of the resistance.

I stand corrected. Thank you.
