The physicistsStephen Wolfram and Brosl Hasslacher introduced me, in the early1980s, to chaos theory and nonlinear systems. In the 1990s, I learnedabout complex systems from conversations with Danny Hillis, the bi-ologist Stuart Kauffman, the Nobel-laureate physicist Murray Gell-Mann, and others. Most recently, Hasslacher and the electrical engineerand device physicist Mark Reed have been giving me insight into the in-credible possibilities of molecular electronics.
