More bowl experiments using solutions to the Thomson problem. see https://www.thingiverse.com/thing:3069580 "Bowl Experiments" The four bowls included here are at three sizes and are derived from four solutions to the Thomson problem, solutions for 25, 40, 60, and 80 electrons. OpenSCAD code is included and can be used to make additional bowls.

These bowls resemble the Voronoi images shown at -http://www-wales.ch.cam.ac.uk/~wales/CCD/Thomson/table.html - a site that lists solutions to the Thomson problem.rnrnThe bowl wall thickness is a minimum, (ca. 1 mm), at positions corresponding to solutions to the Thomson problem. If a bright light is aimed at a bowl and the inside of the bowl viewed, circles of light are seen. The circles are at positions corresponding to Thomson problem solutions.
