GENERAL KNOWLEDGE

Detailed explanation-1: -On December 2, 1942, the world’s first self-sustaining, controlled nuclear chain reaction took place paving the way for a variety of advancements in nuclear science. The experiment took place at the University of Chicago’s football stadium under the direction of Enrico Fermi-a Nobel Prize-winning scientist.

Detailed explanation-2: -Nuclear fission was discovered in December 1938 by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch.

Detailed explanation-3: -In the months before his Stockholm trip, he had sought teaching positions in America and had received offers from five universities. He chose a professorship in Physics at Columbia University. There, in 1939, he confirmed the discovery of the fission process and began striving to attain a nuclear chain reaction.

Detailed explanation-4: -The radiochemists Otto Hahn and Fritz Strassmann were bombarding elements with neutrons in their Berlin laboratory when they made an unexpected discovery.

Detailed explanation-5: -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.
