White Light

Blurb

White Light is a work of science fiction by Rudy Rucker published in 1980 by Virgin Books in the UK and Ace books in the US. It was written while Rucker was teaching mathematics at the University of Heidelberg from 1978 to 1980, at roughly the same time he was working on the non-fiction book Infinity and the Mind.
On one level, the book is an exploration of the mathematics of infinity through fiction, in much the same way the novel Flatland: A Romance of Many Dimensions explored the concept of multiple dimensions. More specifically, White Light uses an imaginary universe to elucidate the set theory concept of aleph numbers, which are more or less the idea that some infinities are bigger than others.
