The Manhattan Project

The Manhattan Project




The Manhattan Project was a classified project created by the US government. It was a group of scientist trying to make a bomb using the atomic theory. There was two ways to make the bomb. One way was the gun way where it shoots uranium into a bigger uranium core which made it explode. The other was the implosive kind where high explosive lenses explode to compress the plutonium core. The US was the first country to find out on how to make the bombs. The two bombs were dropped on Heiroshima and Nagasaki.

"In the course of the last four months it has been made probable — through the work of [Frédéric] Joliot[-Curie] in France as well as [Enrico] Fermi and Szilard in America — that it may become possible to set up a nuclear chain reaction in a large mass of uranium, by which vast amounts of power and large quantities of new radium-like elements would be generated. Now it appears almost certain that this could be achieved in the immediate future." To find this picture and more of this document by Albert Einstein go to wikipedia.org
