I came across a wiki article the other day that mentioned something interesting:

The term "potential theory" arises from the fact that, in 19th-century physics, the fundamental forces of nature were believed to be derived from potentials which satisfied Laplace's equation. Hence, potential theory was the study of functions which could serve as potentials. Nowadays, we know that nature is more complicated: the equations which describe forces are systems of non-linear partial differential equations such as the Einstein equations and the Yang-Mills equations, and the Laplace equation is only valid as a limiting case.</i>

I'm wondering how this happens? In which limit does Laplace emerge? This is probably too far advanced for me to understand, since I don't know Yang-Mills theory and haven't studied the Einstein equations, but I thought I'd throw it out there.

Oops, this is the lab notebook. Okay then, how about creative misuse of lab equipment?
