== J. Arnold Crowther ==
One of the main protagonists in the atomic theory of 1905-1910 is [[James Arnold Crowther]]. Given so many dubiously notable biographies on Wikipedia I was surprised to discover nothing about him here. In addition to his publications on beta scattering, consider published books:
* Crowther, James Arnold. Ions, electrons, and ionizing radiations. Longmans, Green, 1924.
** "Many have owed their first acquainance with modern physics to this excellent intermediate text, which reached its eigth and final edition in 1949, the year before Crowther's death." Heilbron, 1968, footnote on page 296.
* Crowther, James Arnold. A manual of Physics. H. Frowde, 1919.
* Crowther, James Arnold. Molecular Physics. J. & A. Churchill, 1923.
* Crowther, James Arnold. The life and discoveries of Michael Faraday. Society for promoting Christian knowledge, 1920.
His obitutary:
* Whiddington, R. [https://www.nature.com/articles/165750b0.pdf "Prof. JA Crowther."] Nature 165.4202 (1950): 750-751.

== Thomson problem ==
Has anyone ever done a computer simulation of a Thomson atom with 100 or so atoms, arranged in shells like Thomson imagined? The Thomson problem solutions I found online constrain the electrons to the surface of the sphere. [[User:Kurzon|Kurzon]] ([[User talk:Kurzon|talk]]) 16:45, 11 July 2024 (UTC)
