The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Niels Bohr's model of the hydrogen atom—first published 100 years ago and commemorated in a special issue of Nature—is simple, elegant, revolutionary, and wrong. Well, "wrong" isn't exactly ...

Bohr’s atomic orbits . S. Egts. In Bohr’s model of the hydrogen atom, one electron, carrying a negative electrical charge, circles a nucleus consisting of a single proton, which has a positive ...

The model has been superseded since Niels Bohr first proposed it in 1913, as our understanding of the quantum world advanced. Erwin Schroedinger proposed a new atomic model that dispensed with ...

But instead of solving the Bohr-model problem, Hagen applied the “variational principle” – a technique usually reserved for approximating quantum-mechanical systems that cannot be solved analytically ...

In history books, Bohr’s chief contribution to physics is usually said to be “the Bohr atom” — his application in 1912–3 of the still-recent quantum hypothesis to overcome instabilities in ...

“A former student [physics major] got a tattoo of a cartoon atom on the back of one of his legs. He told me that the first day after he got it, he went to rugby practice, and was showing it to someone ...

The Bohr model successfully predicts hydrogen energy levels with good accuracy, but it’s a wrong in every other way. The first problem with the Bohr model is that, like the solar system, it describes ...

Bohr used his model to explain the spectral lines of hydrogen. He also conceived the complementarity principle, wherein items could be separately analysed in terms of contradictory properties, ...
