2. In 1932, James Chadwick was testing alfa particles with beryllium to get electromagnetic radiation but in the reaction, he discovered a “neutral particle” with a mass also known as a Neutron. In 1941, he wrote a MAUD report, which inspired the US government to begin serious atomic bomb research efforts. After building a successful bomb, in 1941, Chadwick’s research group discovered the mass for uranium for a nuclear detonation. In 1943 he moved to the United States to take part in the atomic bomb project. Chadwick attended the Trinity nuclear test on July 16, 1945, when the world’s first atomic bomb was detonated.
