Szilard!?!

Hello,


Iam sure some of your are wondering why I named Szilard, Szilard! The reason is my dad Suggested it! He is reading a book called " The Making of The Atomic Bomb" The first half of the 700 hundred page book is just names of the people who helped make the Bomb! And my dad found Szilard a very intresting name. He asked me to name a boy goat Szilard, so I did! Here is a little info about Leó Szilárd! If you want to read more about his life go to http://en.wikipedia.org/wiki/Leo_Szilard! Thats where i got all this info!!

"In 1933 Szilárd fled to London to escape Nazi persecution, where he read an article written by Ernest Rutherford in The Times which rejected the possibility of using atomic energy for practical purposes. Although nuclear fission had not yet been discovered, Szilárd was reportedly so annoyed at this dismissal that he conceived of the idea of the nuclear chain reaction while walking to work at St Bartholomew's Hospital waiting for traffic lights to change on Southampton Row in Bloomsbury, though his friend Jacob Bronowski notes that he never knew Szilárd to wait for traffic lights. The following year he filed for a patent on the concept. Szilárd first attempted to create a chain reaction using beryllium and indium, but these elements did not produce a chain reaction. In 1936, he assigned the chain-reaction patent to the British Admiralty to ensure its secrecy (GB patent 630726). Szilárd also was the co-holder, with Nobel Laureate Enrico Fermi, of the patent on the nuclear reactor (U.S. Patent 2,708,656 ). In 1938 Szilárd accepted an offer to conduct research at Columbia University in Manhattan, and moved to New York, and was soon joined by Fermi. After learning about nuclear fission in 1939, they concluded that uranium would be the element capable of sustaining a chain reaction. Szilárd and Fermi conducted a simple experiment at Columbia and discovered significant neutron multiplication in uranium, proving that the chain reaction was possible and opening the way to nuclear weapons. Szilárd later described the event: "We turned the switch, saw the flashes, watched for ten minutes, then switched everything off and went home. That night I knew the world was headed for sorrow". At around that time the Germans and others were in a race to produce a nuclear chain reaction. German attempts to control the chain reaction sought to do so using graphite, but these attempts proved unsuccessful. Szilárd realized graphite was indeed perfect for controlling chain reactions, just as the Germans had determined, but that the method of producing graphite used boron carbide rods, and the minute amount of boron impurities in the manufactured graphite was enough to stop the chain reaction. Szilárd had graphite manufacturers produce boron-free graphite. As a result, the first human-controlled chain reaction occurred on 2 December 1942."

I just read all of the Wikipedia’s info on Leó Szilárd so I know way more than I did before! It is all is very interesting and enlightening, but still I am not inclined to read 700 pages about him! I’m glad there are men such as your dad who discerningly read such books.
I thought it quite interesting that, “He often did a lot of his best thinking while taking a bath”. If only it were that simple to have world changing thoughts and ideas, I would certainly take more baths… as opposed to showers!

Thanks for the in-depth info!
