Rudy Rucker
Rucker often uses his novels to explore scientific or mathematical ideas. For example, White Light examines the concept of infinity. Parts of the Ware Tetralogy (written from 1982 through 2000) are an explanation of using natural selection to develop computer software (a subject also developed in his The Hacker and the Ants, written in 1994). His novels also show a mystical philosophy. Rucker explained this philosophy in an essay called The Central Teachings of Mysticism. There may be some irony in this tiitle (The essay is included in Seek!, 1999).
