Michio Kaku (born January 24, 1947)

Michio Kaku is an American physicist, Professor of Theoretical Physics in the City College of New York of City University of New York, the co-founder of string field theory, and a "communicator" and "popularize" of science

                             Kaku was born in San Jose, California to Japanese immigrant parents. Kaku graduated from Harvard University with a B.S. degree in 1968. He received a Ph.D. in 1972 from Berkeley Radiation Laboratory at the University of California, Berkeley and held a lectureship at Princeton University in 1973. Presently, he is engaged in defining the "Theory of Everything", which seeks to unify the four fundamental forces of the universe.

                             Kaku is the author of several doctoral textbooks on string theory and quantum field theory and has published articles in topics superstring theory, supergravity, supersymmetry, and hadronic physics. He is also author of the popular science books: Visions, Hyperspace, Einstein's Cosmos, and Parallel Worlds, and
co-authored Beyond Einstein. Hyperspace was a best-seller and was voted one of the best science books of the year by both The New York Times and The Washington Post. In Physics of the Impossible, he examines the technologies of invisibility, teleportation, precognition, star ships, antimatter engines, time travel and more—all regarded as things that are not possible today but that might be possible in the future. In this book, he ranks these subjects according to when, if ever, these technologies might become reality. In March 2008, Physics of the Impossible entered the New York Times best-seller list, and stayed on for five weeks.

          Kaku has publicly stated his concerns over matters including the anthropogenic cause of global warming, nuclear armament, nuclear power and the general misuse of science. He has also spoken on the dangers of space junk and called for more and better monitoring. Kaku is generally a vigorous supporter of the exploration of outer space, believing that the ultimate destiny of the human race may lie in extrasolar planets; but he is critical of some of the cost-ineffective missions and methods of NASA. Kaku credits his anti-nuclear war position. Kaku joined with others in building a global anti-nuclear weapons movement.
