05:45 Jay Robert Oppenheimer and the scientists at Los Alamos have mixed reactions to the dropping of the atomic bomb on Hiroshima, with some celebrating and others feeling guilty and conflicted.

10:32 Oppenheimer becomes a celebrity and a hero to many Americans after the dropping of the atomic bomb, but he starts to distance himself from his own fame and project, expressing his concerns about the development of the hydrogen bomb.

14:55 Oppenheimer's personality is complex, as he both takes pride in his achievement of the atomic bomb and feels guilt for the destruction it caused, and after leaving Los Alamos, his career as a physicist is effectively over and he becomes a symbol of corporate America and the military industry, while also being under constant surveillance by the FBI and US Army intelligence due to suspicions of his Communist ties.

19:40 Oppenheimer's association with Communists and his role as the director of the Institute of Advanced Study at Princeton raise suspicions about his loyalty and justify the investigations into him.

24:19 Oppenheimer's feud with Lewis Strauss, a member of the Atomic Energy Commission, puts him at risk of being declared persona non grata by the government and brings him closer to being brought down due to suspicions of being a communist agent.

28:45 Oppenheimer's career is at risk as Lewis Strauss and others, including J. Edgar Hoover and Edward Teller, suspect him of being a communist and try to terminate his relationship with the government.

33:33 Oppenheimer's security clearance is suspended and he is put on trial in a public hearing as part of the McCarthyism era.

37:59 Oppenheimer's month-long public hearing reveals that while he did associate with communists and employ them at Los Alamos, there is no evidence of him being a traitor or a security risk to the United States.

42:26 Oppenheimer's loss of security clearance and the subsequent fallout both destroy and make him, as he is ostracized from the establishment but becomes a martyr figure, while his nemesis Lewis Strauss is blocked from a position in the Eisenhower administration due to his treatment of Oppenheimer.

46:53 Oppenheimer's security clearance was never restored, but he was somewhat rehabilitated in his final years, receiving invitations to the White House and a medal from LBJ, while his nemesis Edward Teller shook hands with him at the prize ceremony.
