Electrons are very round

Marcus du Sautoy's book (Number Mysteries) mentions how hard it is for humans to fabricate truly round or spherical objects - most attempts using approximations based on one or other of the Platonic solids. So from a human point of view such roundness is also remarkable...

If I read it correctly, their measurements were able to determine no deviation from a perfect sphere. I think the deviation they list, is the maximum possible variation from a perfect sphere, accounting for the limitations in their measurements' accuracy.

The scientists were able to detect that the electrons were round since if an electron is not spherical in shape its motion will exhibit a distinct wobble that contorts the shape of the rest of the molecule, much like an unbalanced spinning top. As the team witnessed no wobbling they concluded that the electrons were round in shape.
