Abstract

An interesting connection exists between Spence's integral, used in Feynman diagrams in particle physics, and the variance of the reciprocal of a geometric random variable, used in probability theory. This linkage leads to approximate representations for Spence's integral over the unit interval which works well in practice. The result shows how the interplay between probability and physics can bear pragmatic fruit.
