Torricelli[edit]

It seems to me that it was Evangelista Torricelli who disproved horror vacui a few years earlier with his mercury barometer. Von Guericke just invented the air pump and ran popular demonstrations.--Yannick 23:07, 26 September 2007 (UTC)[reply]

What demonstration of electrostatic repulsion[edit]

Lead says "... the discovery of an experimental method for clearly demonstrating electrostatic repulsion" but it's hard to find in the large section on Electrostatic investigations. - Rod57 (talk) 14:29, 28 November 2015 (UTC)[reply]

Biography[edit]

Should the biography be split up into subsections so that readers can find the information they are looking for more quickly? Also, which of the sources is the biographical information coming from? There seems to be a lack of using citations. 18:10, 16 February 2018 (UTC) — Preceding unsigned comment added by Ajfyb4 (talk • contribs)

Shouldn't this page mention his work on the periodicity of comets?[edit]

I came across Guericke at this "Centenaries for 2002" list (Journal of the British Astronomical Association, vol.111, no.6, p.343-344), where it said he "believed that comets were normal members of the solar system and made periodic returns", which led to do a Web search and find "Otto von Guericke’s Cometary Theory in Stanisław Lubieniecki’s Correspondence" (Maciej Jasiński, Journal for the History of Astronomy, June 3, 2020, DOI:10.1177/0021828619891273). It seems noteworthy that he had such a theory in 1666–1668, before Halley's 1705 work (or even Newton's Principia Mathematica of 1687), though I doubt Guericke made specific correct period predictions like Halley, since he didn't have Newton's conic sections orbital theory to work from. I also don't know if Guericke was even the first to suggest periodicity. Perhaps this is clarified in the Jasiński piece, of which I have merely read the public abstract.
