Entity: NUCLEAR-FISSION
Nuclear fission is a process in which the nucleus of a heavy atom is split into two fragments of roughly equal mass, accompanied by the release of a large amount of energy.
Nuclear Fission
Etymology
The term 'nuclear fission' was coined by Otto Frisch, inspired by the process of living cell division known as binary fission.
Definition
Nuclear fission is the subdivision of a heavy atomic nucleus, such as uranium or plutonium, into two fragments of roughly equal mass, resulting in the release of a significant amount of energy.
Historical Context
The discovery of nuclear fission is credited to Otto Hahn and Fritz Strassmann in 1938, with Lise Meitner and Otto Frisch providing the correct interpretation of the results.
Cultural Significance
Nuclear fission has had a profound impact on society, leading to the development of nuclear power plants and nuclear weapons.
Related Concepts
Nuclear fusion, the process of combining two atomic nuclei to form a heavier nucleus, is often contrasted with nuclear fission.
