Noise: A Fuzzy Logic Perspective

Dr. Bart Kosko

Dr. Bart Kosko is Professor of Electrical Engineering, USC, and author of Fuzzy Thinking, Heaven in a Chip, The Fuzzy Future, and Noise

A celebrated maverick in the world of science, Bark Kosko introduced the revolutionary concept of fuzzy logic. In his latest book, upon which this lecture is based, he provides the first scientific history of noise. Noise occurs at every level of the physical universe, from the big bang to blaring car alarms. Today, noise is considered the curse of the information age, but, in fact, not all noise is bad. Debunking this and many other commonly held beliefs about noise, Kosko gives readers a vivid sense of how deeply noise permeates both the world around us and within us, and considers noise’s possible role in the ice ages to noise pollution laws, the use of noise to generate synthetic speech, and Hedy Lamarr’s contribution to noisy wireless communication.
