Vor 4 Tagen · He was sought out by physicist Niels Bohr for one-on-one discussions. He later discovered the reason: most of the other physicists were too much in awe of Bohr to argue with him. Feynman had no such inhibitions, vigorously pointing out anything he considered to be flawed in Bohr's thinking. He said he felt as much respect for Bohr as anyone ...
Vor 2 Tagen · Niels Bohr was the first to propose (1923) that the periodicity in the properties of the elements might be explained by the periodic filling of the electron energy levels, resulting in the electronic structure of the atom. The periodic table may also be divided into several numbered rectangular 'blocks'.
Vor 4 Tagen · In München selbst besuchten viele bekannte Persönlichkeiten das Deutsche Museum, so beispielsweise Henry Ford, Robert Millikan oder Niels Bohr. Der Vorstand um Oskar von Miller vertrat die Auffassung, das Deutsche Museum müsse unpolitisch bleiben, was bereits Mitte der 1920er Jahre zu Anfeindungen durch die Nationalsozialisten führte. Auch ...
Vor 3 Tagen · Bell's theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden-variable theories, given some basic assumptions about the nature of measurement.
Vor 5 Tagen · In a year’s time, Niels Bohr had a model of the hydrogen atom that could explain the spectral lines. Bohr introduced a new concept, the energy level. The electron in hydrogen had certain energy levels that were allowed in which sharp spectral lines came out as emission when the electron hopped from one energy level to another. To explain this level of energy, Bohr developed a model in which ...
Vor 2 Tagen · I’ve seen this done in other productions and just happen to be a curious person – which means after this film, I instantly opened Wikipedia. One thing I want to note – and I wonder if other people noticed this too – is Kenneth Branagh’s accent. He plays Niels Bohr and initially, he actually does a good job on the accent front but then there is a scene where approximately halfway ...
Vor 3 Tagen · Wikipedia sagt: Metall-Ionen sind in der Regel positiv geladen. Was ist mit "in der Regel" gemeint? So wie ich das verstanden habe, sind Ionen geladene Atome mit Elektronenüberschuss bzw. mangel. Als Beispiel nennt Wikipedia Natrium, welches "in der Regel" einfach positiv geladen ist. Ich kann doch aber auch viel Energie aufwenden und einem Natrium Atom 4 Elektronen wegnehmen, damit es 4-fach ...
