John Archibald Wheeler

John Archibald Wheeler is an American theoretical physicist. He was born July 9, 1911 in Jacksonville, Florida. One of the later collaborators of Albert Einstein, he tried to achieve Einstein's vision of a unified field theory.

Wheeler was one of the pioneers of the theory of nuclear fission (with Niels Bohr and Enrico Fermi), and participated in the development of the U.S. atomic bomb under the Manhattan Project at Los Alamos during World War II. Later he went on to participate in the development of the American hydrogen bomb under Project Matterhorn B.

In the 1960s, he formulated the so-called geometrodynamics, a program of physical (and ontological) reduction of every physical phenomenon such as gravitation and electromagnetism to the geometrical properties of a (curved) space-time. Aiming at a systematical identification of matter with space, geometrodynamics has often been said to be a systematic prolongation of the philosophy of nature as conceived by Descartes and Spinoza. Wheeler's geometrodynamics, however, failed to explain some important physical phenomena, such as the existence of fermions or that of gravitational singularities. Wheeler himself therefore abandoned this theory in the early 1970s.

Wheeler has made some very important contributions to theoretical physics. His career has included work on the theory of gravitational collapse, and he coined the term "black hole." Later he was also a pioneer in the field of quantum gravity studies with his development (with Bryce DeWitt) of the Wheeler-DeWitt equation or "wave function of the Universe."

Professor Wheeler had a colorful style of presentation, characterized by expressions like mass without mass. It is therefore fitting that the festschrift for his sixtieth birthday was entitled Magic Without Magic: John Archibald Wheeler: A collection of essays in honor of his sixtieth birthday, Ed: John R. Klauder, (W. H. Freeman, 1972, ISBN 0716703378).

He is also known for making interesting quotes; one of the best known is: "Time is what prevents everything from happening at once."
