Here are some examples of both. Atomic models. Textbooks often use the Bohr model to depict atoms, portraying electrons as neatly orbiting a nucleus in fixed paths. Although this model is visually ...

THE beautiful conception which inspires and co-ordinates practically the whole of modern atomic physics is the atomic model of Rutherford and Bohr. Its essential feature-the nucleus-was first put ...

ABSTRACT: Quantum mechanics (QM) is an extremely successful theory; however, there is still no consensus regarding its interpretation. Among the controversies, the quantum classical transitions are ...

ENGLISH readers will welcome this authoritative account by Prof. Bohr of the application of his theory to atomic structure. The essay has been translated from the Zeitschrift fur Physik by L.

Why even physicists still don’t understand quantum theory 100 years on Bohr started with a picture in which electrons circle the atomic nucleus, rather as planets orbit a star. He postulated ...

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your ...

Bohr made numerous contributions to physics during his career, but it was his work on atomic structure and quantum theory that won him the 1922 Nobel Prize for Physics. (Courtesy: Sam Falconer, Debut ...

an unfinished revolution By supposing that electrons move in elliptical orbits around an atomic nucleus, subject to certain quantization conditions, the Bohr–Sommerfeld model provided a set of ...
