    • Project to develop first Atomic Bomb
    • Specifically between 1942-1946
    • Resulted in Destruction of Hiroshima and Nagasaki
      • End of war with Japan
  • Who
    • Under jurisdiction of the US Army Corps of Engineers
    • General Leslie R. Groves
    • J. Robert Oppenheimer
    • Einstein
    • Fermi
    • FD Roosevelt
  • Einstein and The Bomb
    • Szilard consults Einstein about German Potential
    • The Roosevelt letter-1939
    • Leads to Uranium Committee
    • Severe guilt
  • J. Robert Oppenheimer
    • Physics professor at UC Berkeley
    • Invited to work on the “Uranium Committee”
    • Unlikely Candidate for Groves’ second in command
      • Seen as being best man to lead the diverse team
    "Now I am become Death, the destroyer of worlds."- J.R.O.
  • L.R. Groves
    • Took over in 1942 for J. Marshal
      • Marshal was moving too slow
    • Coined “Manhattan” name
    • Prioritized research and development well
  • L.R. Groves
    • Chose development sites and targets
    • Involved in acquiring information about German research
    • Shadowed project in unprecedented security
      • Unable to prevent Russian espionage
  • Fermi
    • Italian Physicist
    • Chicago Pile-1
      • The first self sustained nuclear reaction
  • Development
    • American and British attempts as early as 1939
    • 1942 control was transferred to US military
      • More serious efforts
    • 1944 Productions plants were constructed
  • Development
    • Multi-pronged pursued multiple theories and designs
    • Plutonium and Uranium
      • The plutonium came from Fermi’s reactors
    • Very Secretive
  • Tritinity
    • 1945- Los Alamos
    • “Fat man”
      • Testing the implosion design
    • Beginning of Atomic Age
    • Disproved “Nuclear Ignition of Atmosphere”
  • The Bombs
    • Two types of Fission design
    • “Fat man” vs. “Little boy”
      • Implosion and Gun type
    • Uranium-238
  • Plutonium Bomb
    • Plutonium-239
    • Hanford site refined the plutonium
    • Nagasaki
  • Uranium
    • Uranium-235
    • Oak Ridge site refined the Uranium

    • “Soviet Atomic Bomb Project”
      • Soviet espionage
    • The Chevalier Incident
  • Hiroshima/Nagasaki
    • 1945
  • Aftermath
  • Results
    • Arguably most important scientific advance of the century
    • 200,000 Japanese people in a matter of seconds
  • Post-War
    • Two Scientists irradiated to death accidentally
    • Atomic Energy Act of 1946
      • United states Atomic Energy Commission
  • Discussion time
    • Knowing what you do about Pearl Harbor and the Japanese habits during the war, was the destruction of the two cities justified?
    • How do you think the remainder war would have been different had the United States not dropped the Bomb?
    • Had the bomb not been dropped how would the Cold War period be different?
