Nuclear fission was discovered in December 1938 by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch. Fission is a nuclear reaction or radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei and often other particles.
The discovery of nuclear fission occurred in 1938 in the buildings of the Kaiser Wilhelm Society for Chemistry, today part of the Free University of Berlin, following over four decades of work on the science of radioactivity and the elaboration of new nuclear physics that described the components of atoms.
The first light bulbs ever lit by electricity generated by nuclear power at EBR-1 at Argonne National Laboratory-West, 20 December 1951. [12] As the first liquid metal cooled reactor, it demonstrated Fermi's breeder reactor principle to maximize the energy obtainable from natural uranium, which at that time was considered scarce.
In November, Russia completes the first test of the 9M730 Burevestnik, the first nuclear-powered cruise missile and the first nuclear-powered aircraft of any kind. [150] [151] 2018. In December, the Taishan 1 EPR begins operation in Guangdong, China. At 1660 MWe it is the largest nuclear reactor unit by electrical power ever. [152] [153] 2019
Only a few years later, in December 1938 nuclear fission was discovered by Otto Hahn and his assistant Fritz Strassmann. Hahn understood that a "burst" of the atomic nuclei had occurred. [8] [9] Lise Meitner and Otto Frisch gave a full theoretical interpretation and named the process "nuclear fission".
Nuclear fission is a substantial part of the world’s energy mix, but out in the broader universe, fission is much harder to come by. Now, a new study from Los Alamos National Laboratory and ...
In 1944, Hahn received the Nobel Prize for Chemistry for the discovery of nuclear fission, although Fritz Strassmann had been acknowledged as an equal collaborator in the discovery. [13] [14] From 1939 to 1946 working at the Kaiser-Wilhelm Institute, Strassman contributed to research on the fission products of thorium, uranium, and neptunium.
Human DNA recovered from remains found in Europe is revealing our species’ shared history with Neanderthals. The trove is the oldest Homo sapiens DNA ever documented, scientists say.
