How do we solve the 4 body problem?

We solve it for n, then set n to 4.

Wish I could find the paper since it was really good. Basically a physicist approach to the sorites problem: what value of N particles corresponds to a continuum that can effectively be modeled as infinitely many? They found N = 4 was surprisingly well approximately as large N.
