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.
