Theoretical Physicist
Michio Kaku is a theoretical physicist and the Henry Semat Professor at the City College of New York and the Graduate Center of the City University of New York, where he has taught for more than 30 years. He is a graduate of Harvard University in Cambridge, Massachusetts, and earned his doctorate from the University of California at Berkeley.
Kaku is one of the founders of string field theory, a field of research within string theory. String theory seeks to provide a unified description for all matter and the fundamental forces of the universe; its key idea is that all particles in the universe are manifestations of the same type of minuscule, vibrating building block called a string. String field theory is an approach seeking to meld the new ideas of string theory with the powerful language used to describe elementary particles to yield a complete description of string dynamics.
Kaku is a tireless popularizer of science. He has written several best-selling popular books, including Hyperspace, selected as one of the best science books of 1994 by both the New York Times and The Washington Post, and Parallel Worlds, a finalist for the Samuel Johnson Prize. His latest, Physics of the Impossible, is a New York Times best-selling book. He is active in both television and radio, working with the BBC and the Discovery Channel and hosting two weekly radio programs which reach 130 cities.
