er research was held in the UK. In February of 1940 two physicists living in the UK, developed an analysis for fast fission. Their names were Otto Frisch and Rudolf Peierls. These two men came to new ideas in developing an Atomic Bomb. Upon their presentation they discovered the mass, efficiency and other strong ideas for the design and construction that would be the best for the U-235. Their report spread quickly to scientists and top officials who had been appointed to building the atomic bomb. These two men changed the whole idea of the Atomic Bomb. Once their report had reached the Briggs Committee, the committee was so persuaded that they again started to work on the A-Bomb project. (URL, The Manhattan Project. P.2)
             On April 10, 1940 the highest levels of government formed a new committee, in regards to the convincing report that Frisch and Peierls had given. They named the Committee MAUD. (Day of the Bomb P.62) This committee decided upon the idea of using gaseous diffusion as the most promising component for Uranium enrichment. (URL, The Manhattan Project. P.2) Between April of 1940 and 1941 work in the US increased immensely for the Manhattan Project. In 1941 Philip Abelson and Arthur Wahl developed new systems for uranium and plutonium development. With these new ideas it enabled Peierls to calculate the first estimated mass of the U-235, which was 10 lb when surrounded by a reflector. In testing these men found that Plutonium demonstrated itself to be the most useful component for fissile material. (URL, The Manhattan Project. P.2) Once all of the ideas and testing had
