I. The History of the Atomic Bomb
------------------------------

On August 2nd 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 U-235
with which might in turn be used to build an atomic bomb. It was shortly
thereafter that the United States Government began the serious undertaking
known only then as the Manhattan Project. Simply put, the Manhattan Project
was committed to expedient research and production that would produce a viable
atomic bomb.

The most complicated issue to be addressed was the production of ample
amounts of `enriched' uranium to sustain a chain reaction. At the time,
Uranium-235 was very hard to extract. In fact, the ratio of conversion from
Uranium ore to Uranium metal is 500:1. An additional drawback is that the 1
part of Uranium that is finally refined from the ore consists of over 99%
Uranium-238, which is practically useless for an atomic bomb. To make it even
more difficult, U-235 and U-238 are precisely similar in their chemical
makeup. This proved to be as much of a challenge as separating a solution of
sucrose from a solution of glucose. No ordinary chemical extraction could
separate the two isotopes. Only mechanical methods could effectively separate
U-235 from U-238. Several scientists at Columbia University managed to solve
