Il y a 6 jours · Hans Albrecht Bethe ( German pronunciation: [ˈhans ˈbeːtə] ⓘ; July 2, 1906 – March 6, 2005) was a German-American theoretical physicist who made major contributions to nuclear physics, astrophysics, quantum electrodynamics, and solid-state physics, and who won the 1967 Nobel Prize in Physics for his work on the theory of ...
28 juin 2024 · Hans Bethe was a German-born American theoretical physicist who helped shape quantum physics and increased the understanding of the atomic processes responsible for the properties of matter and of the forces governing the structures of atomic nuclei. He received the Nobel Prize for Physics in 1967.

Il y a 4 jours · Le projet Manhattan est le projet de recherche du gouvernement américain dont l'objectif était de produire une bombe atomique au cours de la Seconde Guerre mondiale. Il fut progressivement mené de manière conjointe avec les gouvernements britannique et canadien.
25 juin 2024 · Une production de particules prédite par l'électrodynamique quantique. Plus précisément, le physicien Charles Arrowsmith et ses collègues ont mis à profit un processus déjà décrit théoriquement en...
Il y a 4 jours · A theory verified by Hans Bethe in 1939 showed that beta decay and quantum tunneling in the Sun's core might convert one of the protons into a neutron and thereby produce deuterium rather than a diproton. The deuterium would then fuse through other reactions to further increase the energy output.
Il y a 1 jour · At Los Alamos, Feynman was assigned to Hans Bethe's Theoretical (T) Division, and impressed Bethe enough to be made a group leader. He and Bethe developed the Bethe–Feynman formula for calculating the yield of a fission bomb, which built upon previous work by Robert Serber. As a junior physicist, he was not central to the project.
26 juin 2024 · The German-born physicist Hans Bethe proposed in the 1930s that the H-H fusion reaction could occur with a net release of energy and provide, along with subsequent reactions, the fundamental energy source sustaining the stars. However, practical energy generation requires the D-T reaction for two reasons: first, the rate of reactions ...
