Toroidal ring model - Wikipedia
https://en.m.wikipedia.org/wiki/Toroidal_ring_model
The toroidal ring model, known originally as the Parson magneton or magnetic electron, is a physical model of subatomic particles. It is also known as the plasmoid ring, vortex ring, or helicon ring. This physical model treated electrons and protons as elementary particles, and was first proposed by Alfred Lauck Parson in 1915.

Lev Landau - Scientist of the Day - Linda Hall Library
https://www.lindahall.org/lev-landau/
In addition to his award-winning work in #physics, he is also remembered for a scale he devised to rank 20th-century physicists. It was an exponential scale, according to which 0 was the highest possible (indeed infinite) score, followed by 1 through 5, and because the scale was logarithmic, a “1” was considered 10 times more productive than a “2”, and a “2” ten times better than a “3”. #Newton was a “1”, as were Niels #Bohr and Paul #Dirac and several others. #Einstein was given the highest rank, a “0.5”, which made him about three times smarter, or at least more productive, than Newton and Bohr. #Landau initially ranked himself as a “2.5”, but later decided that he really deserved to be a “2” and moved himself up the scale.
