Vor 2 Tagen · 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. Mai 2024 · These experiments were rapidly followed by the first non-relativistic diffraction model for electrons by Hans Bethe based upon the Schrödinger equation, which is very close to how electron diffraction is now described.
Vor 2 Tagen · 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. For this work, Bethe won the 1967
30. Mai 2024 · Hans Bethe, a renowned physicist and Nobel laureate, was not only an extraordinary scientist but also an inspirational figure whose contributions to the field of physics have had a profound impact on our understanding of the universe.
18. Mai 2024 · 1933 berechneten Hans Bethe und Arnold Sommerfeld näherungsweise die Tunnelstromdichte zwischen zwei Elektroden mit geringer Potentialdifferenz und trapezförmiger Potentialbarriere. Eine etwas bessere Näherung konnte dann 1935 von R. Holm und B. Kirschstein angegeben werden, die die Form der Potentialbarriere mit einer Parabel ...
13. Mai 2024 · Die Bethe-Weizsäcker-Formel ist eine Formel zur Beschreibung der Bindungsenergie von Atomkernen nach dem Tröpfchenmodell. Bindungsenergie kann als negative potenzielle Energie betrachtet werden. Im Tröpfchenmodell werden die Nukleonen wie Moleküle eines inkompressiblen geladenen Flüssigkeitströpfchens betrachtet.
9. Mai 2024 · With the head of that division, Hans Bethe, he devised the formula for predicting the energy yield of a nuclear explosive. Feynman also took charge of the project’s primitive computing effort, using a hybrid of new calculating machines and human workers to try to process the vast amounts of numerical computation required by the project. He ...
