2 Background  European scientists came to America  They asked Roosevelt for money to fund nuclear research  Told him the Germans were also making atomic weapons  Wanted to beat them in the race

3 Nuclear Fission  Neutron fired at radioactive atom  Atom splits and releases large amounts of energy and more neutrons

4 Chain Reaction  Create self-sustaining reaction  Try to stop the reactor before it explodes

5 Nuclear Reactor  Graphite blocks and cadmium rods surrounding uranium nuggets  At 9:30, November 8, 1942 self- sustaining chain reaction produced

6 Who was involed?  Before WWI James Franck and Gustav Hertz did experiments on fission  Otto Hahn and Lise Meitner discovered nuclear isomers and more about uranium  In 1942 the Manhattan Engineer Project was set up led by Leslie Groves

7 American Scientists  Robert Oppenheimer started working on the development of the atomic bomb  He was invited to lead the research fast neutron calculations  Groves then appointed Robert as the projects scientific director  Ernest Lawrence helped the investigations of the weapon using nuclear fission His Rad Lab became famous for the Manhattan project

8 European Scientists  Enrico Fermi was best know for building the first Nuclear Reactor  Leo Szilard created the Manhattan Project  He talked to Albert Einstein who wrote the letter to the president warning him about the Nazi Atomic Bomb

9 Testing of Atomic bomb  First test July 16,1945  In a desert in New Mexico  Testing was successful

10 Use of the Atomic bomb  After the tests used on Japan  The little boy was dropped on Hiroshima  The Fat man was dropped on Nagasaki
