The atomic bomb (slideshare version)

  1. 1. The Atomic Bomb
  2. 2. Summary of Effects The atomic bombs that were dropped were the first kind of nuclear weapons that the world had seen. All nuclear weapons get their destructive power from nuclear reactions of fusion, or fission. Nuclear reactions of fusion happen when two nuclear particles collide with each other to create products that are different from the orignal particles. Fission occurs when the nucleus of an atom is split. When this happens, gamma rays are emitted. If fission occurs, high amounts of energy in the form of radiation are released.

  9. 9. Quotation From an Expert We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita. Vishnu is trying to persuade the Prince that he should do his duty and to impress him takes on his multi-armed form and says, "Now I am become Death, the destroyer of worlds." I suppose we all thought that, one way or another. -J. Robert Oppenheimer A response from Oppenheimer, mastermind behind the atomic bomb, after being interviewed about his creations.
