MIT，CalTech主要是贡献人吧，Princeton开始还有个组，后来被集中到Chicago了。这些搞铀的探索主要是大伯小芝和老哥。初始的裂变探索好像集中在小芝和大伯，没老哥啥事。
Arthur Compton, the chairman of the University of Chicago physics department, coordinated the uranium research of Columbia University, Princeton University, the University of Chicago, and the University of California, Berkeley. To remove disagreement and duplication, Compton transferred the scientists to the Metallurgical Laboratory at Chicago。
To review this work and the general theory of fission reactions, Oppenheimer and Fermi convened meetings at the University of Chicago in June and at the University of California, Berkeley, in July 1942 with theoretical physicists Hans Bethe, John Van Vleck, Edward Teller, Emil Konopinski, Robert Serber, Stan Frankel, and Eldred C. Nelson, the latter three former students of Oppenheimer, and experimental physicists Emilio Segrè, Felix Bloch, Franco Rasetti, John Henry Manley, and Edwin McMillan. They tentatively confirmed that a fission bomb was theoretically possible.
