Introduction

The First Nuclear Bombimage00.jpg

Scientists Who Invented the Atomic Bomb under the Manhattan Project: Robert Oppenheimer, David Bohm, Leo Szilard, Eugene Wigner, Otto Frisch, Rudolf Peierls, Felix Bloch, Niels Bohr, Emilio Segre, James Franck, Enrico Fermi, Klaus Fuchs and Edward Teller.

On August 2, 1939, just before the beginning of World War II, Albert Einstein wrote to then President Franklin D. Roosevelt. Einstein and several other scientists told Roosevelt of efforts in Nazi Germany to purify uranium-235, which could be used to build an atomic bomb. It was shortly thereafter that the United States Government began the serious undertaking known then only as "The Manhattan Project.

A massive enrichment laboratory/pla nt was constructed at Oak Ridge, Tennessee. Harold Urey and his colleagues at Columbia University devised an extraction system that worked on the principle of gaseous diffusion, and Ernest Lawrence (inventor of the Cyclotron) at the University of California in Berkeley implemented a process involving magnetic separation of the two isotopes. Next, a gas centrifuge was used to further separate the lighter U-235 from the heavier, non-fissionable U-238. Once all of these procedures had been completed, all that needed to be done was to put to the test the entire concept behind atomic fission ("splitting the atom," in layman's terms).

Conclusion

Upon witnessing the explosion, its creators had mixed reactions. Isidor Rabi felt that the equilibrium in nature had been upset as if humankind had become a threat to the world it inhabited. Robert Oppenheimer, though ecstatic about the success of the project, quoted a remembered fragment from the Bhagavad Gita. "I am become Death," he said, "the destroyer of worlds." Ken Bainbridge, the test director, told Oppenheimer, "Now we're all sons of bitches."

After viewing the results several participants signed petitions against loosing the monster they had created, but their protests fell on deaf ears. The Jornada del Muerto of New Mexico would not be the last site on planet Earth to experience an atomic explosionimage00.jpg

Beta particles are released if a nucleus has too many neutrons for the protons; it is believed they break down into a proton, an electron and an antineutrino. The proton stays in the nucleus while the electron and the antineutrino are ejected with a great deal of energy.
