A professor of electrical engineering, Bart Kosko is known as one of the pioneer theorists behind the intriguing fuzzy logic theory. This revolutionary idea is used in computer programming and recognizes that reality is not as clear-cut as the traditional binary system of yes/no computer responses allows. Fuzzy logic theory allows calculations to be performed that recognize the gray area between absolutes so that responses might be made based on percentages, such as seventy percent of one thing or thirty percent of another, rather than all or nothing. Kosko's work, while still cutting-edge, is already being used in some of today's technology. For example, it permits camcorders with computer chips to more accurately focus lenses and is used in computerized automatic transmissions in cars to allow them to shift gears more smoothly and efficiently; it may also be used in future artificial intelligence technology. The engineer first published his ideas in Neural Networks and Fuzzy Systems: A Dynamical Systems Approach to Machine Intelligence. Not meant for the general reader, the textbook includes mathematical exercises on an accompanying computer disk that are aimed at those who understand linear algebra and advanced calculus. The work explains how to integrate fuzzy logic into neural networks.
Kosko followed this work up with books that are more friendly toward the general reader: Fuzzy Thinking: The New Science of Fuzzy Logic and The Fuzzy Future: From Society and Science to Heaven in a Chip. The title of Fuzzy Thinking might lead one to believe it is a book on sloppy logic, but Kosko patiently explains his ideas, which some critics have observed are based on Eastern ways of thinking rather than on the Aristotelian tradition of the West. "Writing with style and risk, Kosko challenges assumptions," remarked a Publishers Weekly critic.
The Fuzzy Future is Kosko's look ahead at the possibilities of a fuzzy logic revolution. The engineer sees it as influencing everything from technology and medicine to politics and art. He even speculates that a computer chip might be developed that could be used to download people's personalities, thus making them immortal. The consequences of this type of engineering might not always be positive for humanity, however, and the author makes "the disturbing prediction that cruise missiles guided by fuzzy logic chips will become so cheap and accurate that attacking an enemy will become more cost-effective than defending against him," reported Jeff Minerd in a Futurist review. Minerd went on to comment that much of the text is philosophical, not practical, in nature, and that it will be enjoyed more by readers who like to indulge in speculation than those "looking for detailed descriptions of future technological marvels." "Fairly demanding, but certain to appeal to readers curious about where leading-edge computer types are headed," commented Mary Carroll in Booklist.
Indulging in some speculation himself, Kosko imagined a world influenced by fuzzy logic technology in his first novel, Nanotime. The story is about a future world where oil is almost depleted and countries are on the verge of World War III. The hero, John Grant, invents a molecule that will allow hydrogen to be used as an efficient and cheap form of fuel, replacing the need for oil. He soon finds himself to be the rope in an international tug-of-war between those who want to kidnap him for their own use and those who wish to kill him so that their oil reserves do not become worthless. While critics found the concept of the book intriguing, many were not impressed by Kosko's fiction-writing skills. "Kosko's abilities to plot and develop characters aren't equal to his skills at the speculative blackboard," as one Publishers Weekly contributor put it, adding that the hero "is thoroughly unpleasant." Robert C. Moore, writing in the Library Journal, found the plot "tedious" and that it had a "disappointing finish for such a promising story."
Kosko was back in his element with his next nonfiction work, Noise. The book is literally about the concept of noise, which is "defined as any unwanted signal," as one Science News writer explained. Noise is usually considered an irritant, something that gets in the way of reception, but Kosko points out that noise can be a good thing at times. For example, when skillfully applied, it can actually be used to enhance signal transmissions. Kosko covers all forms of noise and its issues, including environmental impacts (disturbing the communications of whales, for example) and legal issues (Kosko, a licensed attorney as well as scientist, goes into some depth on such topics as public nuisance laws). Booklist contributor David Pitt declared Noise "an endlessly fascinating book" by "an engaging writer." "Heady reading from a polymath popularizer," concluded a Kirkus Reviews writer, "but exhilarating nonetheless."
