Michio Kaku (String Theory)

Physicist Michio Kaku has been one of the most vocal supporters of string theory. He worked on the theory early in the 1970s, actually co-founding “string field theory” by writing string theory in a field form. By his own account, he then abandoned work on string theory because he didn’t believe in the additional dimensions the theory demanded. He returned to string theory during the first superstring revolution and has proven an entertaining and lucid spokesman ever since.
Dr. Kaku wrote one of the first popular topics on the topic, Hyperspace: A Scientific Odyssey Through Parallel Universes, Time Warps, and the 10th Dimension, in 1994. (This was my first introduction to string theory, when I read the topic as a high school senior.) He has since written other topics on futurism and advanced scientific and technology principles. His 2005 topic, Parallel Worlds, focuses on many topics related to string theory.
For more than 25 years, Kaku has been a professor of theoretical physics at the City College of New York. The close proximity to major television networks may explain why he regularly appears on so many television programs. With a distinctive mane of white hair, Dr. Kaku is easily recognizable when he makes appearances on CNN, Discovery, the Science Channel, or ABC’s Good Morning, America. (When GMA needed someone to explain how Mentos cause soda bottles to erupt into fountains of fizz, they called in Dr. Kaku.)
Kaku has also hosted a number of programs, including two of his own radio shows. He is currently seen hosting the SciQ Sunday specials on the Science Channel. His research work on the subject of string theory isn’t as impressive as the others on this list, but he has done an incredible amount to popularize the ideas of string theory. Many recognize him as one of the theory’s most vocal proponents to layman audiences.
