GENERAL KNOWLEDGE

Detailed explanation-1: -Enrico Fermi (Italian: [enˈriːko ˈfermi]; 29 September 1901 – 28 November 1954) was an Italian and later naturalized American physicist and the creator of the world’s first nuclear reactor, the Chicago Pile-1. He has been called the “architect of the nuclear age” and the “architect of the atomic bomb".

Detailed explanation-2: -When scientists convinced President Roosevelt of this, Fermi was appointed to head a research team as part of a secret project to develop an atomic bomb. Fermi’s task, however, was to create a controlled nuclear reaction; that is, to split the atom without creating a deadly explosion.

Detailed explanation-3: -While at Columbia, Fermi found that when uranium neutrons were emitted into another batch of fissioning uranium, they would split the uranium atoms and set off a chain reaction, thus releasing a tremendous amount of energy.
