Niels Bohr's Nobel Lecture on December 11, 1922, titled The Structure of the Atom, is one of the most significant contributions to our understanding of atomic structure and quantum mechanics. This ...

This release is available in German. Planets can orbit a star for billions of years. Electrons circling the atomic nucleus are often visualized as tiny planets. But due to quantum effects, the ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly ...

Researchers in Denmark have measured the lifetime of an extremely stable energy level of magnesium atoms with great precision. Magnesium atoms are used in research with ultra-precise atomic clocks.

THE arrangement of the non-nuclear electrons in the atom is being determined by work along two lines: first, from the Bohr-Summerfeld theory of characteristic frequencies, and, secondly, from the ...

The planet Jupiter keeps asteroids on stable orbits -- and in a similar way, electrons can be stabilized in their orbit around the atomic nucleus. Calculations have now been verified in a new ...

IN connection with the problem of the constitution of the atom discussed in my letter to NATURE of March 24 last (vol. 107, p. 104), I should like to add a few complementary remarks about the manner ...
