LOG#183. Bohrlogy: some pocket formulae.

This post continues the Bohrlogy thread I did some time ago. It aims to parallel electric Bohr (atom), the gravitational Bohr atom and the black hole atom (as new!). Note that , and , . First of all, the common … Continue reading

LOG#171. From Bohrlogy to dualities.

Old (old fashioned!) Quantum Mechanics is understood as the quantum theory before its final formulation around 1927-1931…It includes the Bohr model, the Wilson-Bohr-Sommerfeld quantization and some other tricks like the one to take into account the finite nuclear size. For … Continue reading

LOG#151. Bohrlogy (I).

The Bohr model of the hydrogen atom is a cool and nice “toy model”. It serves as a prototype in many applications, even if it is not fully “quantum”. It does provide many applications. In this post, and the followings, … Continue reading

LOG#114. Bohr’s legacy (II).

Dedicated to Niels Bohr and his atomic model (1913-2013) 2nd part: Electron shells, Quantum Mechanics and The Periodic Table Niels Bohr (1923) was the first to propose that the periodicity in the properties of the chemical elements might be explained … Continue reading
