They called this 20x6x25 foot setup chicago pile number one or cp 1 for shortand it was here they obtained worlds the first controlled nuclear chain reaction on december 2 1942. A nuclear weapon also called an atom bomb nuke atomic bomb nuclear warhead a bomb or nuclear bomb is an explosive device that derives its destructive force from nuclear reactions either fission fission bomb or from a combination of fission and fusion reactions thermonuclear bombboth bomb types release large quantities of energy from relatively small amounts of matter.

Nuclear fission was discovered in december 1938 by physicists lise meitner and otto robert frisch and chemists otto hahn and fritz strassmannfission is a nuclear reaction or radioactive decay process in which the nucleus of an atom splits into two or more smaller lighter nuclei. In the years after world war ii many countries were involved in the further development of nuclear fission for the purposes of nuclear reactors and nuclear weapons.

In nuclear fission the nucleus of an atom breaks up into two lighter nuclei. The process may take place spontaneously in some cases or may be induced by the excitation of the nucleus with a. August 6 2020 marks the 75th anniversary of the dropping of the first atomic bomb.

The fission process often produces gamma rays and releases a very large amount of energy even by the energetic. Nuclear fission subdivision of a heavy atomic nucleus such as that of uranium or plutonium into two fragments of roughly equal massthe process is accompanied by the release of a large amount of energy. Ivanov sam nunn this weekend marks the 100th anniversary of the end of the first world war one of the worlds most horrific conflicts.
