J. Robert Oppenheimer (born Julius Robert Oppenheimer; / ˈ ɒ p ən h aɪ m ər / OP-ən-hy-mər; April 22, 1904 – February 18, 1967) was an American theoretical physicist who served as the director of the Manhattan Project's Los Alamos Laboratory during World War II.
Rebecca Oppenheimer is an American astrophysicist and one of four curator/professors in the Department of Astrophysics at the American Museum of Natural History (AMNH) on Manhattan's Upper West Side. Oppenheimer is a comparative exoplanetary scientist. She investigates planets orbiting stars other than the Sun.
Oppenheimer and Snyder did, however, refer to an earlier article by Oppenheimer and Volkoff on neutron stars, improving upon the work of Lev Davidovich Landau. [7] Previously, and in the same year, Oppenheimer and three colleagues, Richard Tolman , Robert Serber , and George Volkoff , had investigated the stability of neutron stars, obtaining ...
[Before World War II] Oppenheimer’s reputation and influence were centered around the small and close circle of physicists. As the wartime director of Los Alamos Laboratory, he was bound to receive important public attention, but there were other directors of great laboratories, and other physicists, who shared equal esteem but did not become objects of such general interest.
David Paul Saltzberg is an experimental particle physicist and a professor at the University of California, Los Angeles, who is known for his science consultancy work on various television shows and films, such as The Big Bang Theory, [1] Manhattan [2] and Oppenheimer. [3]
1939 – Robert Serber, George Volkoff, Richard Tolman, and J. Robert Oppenheimer study the stability of neutron stars, obtaining the Tolman–Oppenheimer–Volkoff limit. [115] [116] [114] 1939 – J. Robert Oppenheimer and Hartland Snyder publish the Oppenheimer-Snyder model for the continued gravitational contraction of a star. [117] [114] [118]
Oppenheim obtained a bachelor's degree at the University of Toronto in 1993 and PhD at the University of British Columbia in 2001. His PhD thesis titled Quantum Time, focused on time ordering in quantum mechanics and was supervised by Bill Unruh.
Oppenheimer believes that anatomically modern humans crossed the Red Sea from the Horn of Africa and followed the "southern coastal route" once in Asia. Thus Oppenheimer is opposed to the theory that there was another out of Africa migration using a northern route along the Nile and into the Levant as suggested by Lahr and Foley 1994. [4]
