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.
In nuclear fission events the nuclei may break into any combination of lighter nuclei, but the most common event is not fission to equal mass nuclei of about mass 120; the most common event (depending on isotope and process) is a slightly unequal fission in which one daughter nucleus has a mass of about 90 to 100 daltons and the other the ...
The first light bulbs ever lit by electricity generated by nuclear power at EBR-1 at Argonne National Laboratory-West, December 20, 1951. [7]The process of nuclear fission was discovered in 1938 after over four decades of work on the science of radioactivity and the elaboration of new nuclear physics that described the components of atoms.

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. Until now.
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".
A frightening moment in the 1950s has mostly been forgotten today — the release of an unloaded nuclear bomb by the Air Force over the Palmetto State. That time the U.S. government accidentally ...
With the help of Axiom 3 astronauts on the International Space Station, a cancer "kill switch" drug may make it to clinical trials before year's end.
