Judea Pearl, chancellor's professor of computer science and statistics at UCLA, has written his first book intended for a general audience, "The Book of Why: The New Science of Cause and Effect." The book, which was written with co-author Dana Mackenzie, explores causality -- the study of cause and effect -- from its origins to its applications at the leading edges of science. Pearl, a UCLA faculty member since 1970, received the 2011 A.M. Turing Award, considered the "Nobel Prize" in computing, for his landmark work in processing information under uncertainty. His new book will be published on May 15. That same day, Pearl will deliver a talk at the Charles E. Young Research Library as part of the UCLA Library Writer Series.
