Study Notes

Heisenberg's Background

  • Werner Heisenberg was born in Germany.
  • After WWI, he dedicated his work to quantum physics.
  • Heisenberg's formulation of the "uncertainty principle" earned him the Nobel Prize.

Oppenheimer's Role

  • J. Robert Oppenheimer was a professor instrumental in nuclear physics.
  • He chose Los Alamos, New Mexico as the base for developing the first atomic bomb.

Significance of Nuclear Fission

  • Splitting an atom releases massive energy, capable of creating nuclear bombs.
  • The key ingredient for constructing an atomic bomb is uranium.

Development of the Atomic Bomb

  • The U.S. initiated the Manhattan Project to develop the atomic bomb, pushed by Enrico Fermi.
  • When uranium supplies were deemed insufficient, plutonium became the alternative.

Key Components of a Plutonium Bomb

  • The critical mechanism for a plutonium bomb is implosion.

International Espionage and Loyalty Concerns

  • Heisenberg faced scrutiny from the Nazis due to his connections with Jewish scientists, raising doubts about his loyalty.
  • Concerns about preventing Heisenberg from developing an atomic bomb led to plans for his assassination.

Testing and Financial Aspects

  • The first atomic bomb tested in New Mexico was nicknamed "gadget."
  • Developing the bomb cost nearly US $2 billion and had an explosive equivalence of 20,000 tons of TNT.

Deployment of Atomic Bombs

  • The first atomic bomb was dropped on Hiroshima, Japan.

Heisenberg's Deception

  • Heisenberg’s critical falsehood was that he had deliberately sabotaged the Nazi bomb effort.
