Origin of polhode?
[edit]"Polhode" is used in connection with the motion of the Earth's Pole. As to herpolhode, the repetitious loops along a circular path in the invariable plane suggest the coils of a snake and the circumpolar constellation Draco might encouraged this usage. Both terms are used in association with tops. --Jbergquist 02:53, 29 June 2006 (UTC)
Pitures?
[edit]How can an article about a "geometric method for visualizing" something have no pictures in it? 168.150.253.56 15:25, 22 October 2007 (UTC)
...Still no picture. 110.39.215.19 (talk) 11:02, 13 March 2012 (UTC)
"geometric method for visualizing" -- I thought the exact same thing. No images for something about visualization = fail. — Preceding unsigned comment added by 98.20.255.246 (talk) 23:33, 16 November 2013 (UTC)
I don't know how anything works on Wikipedia, but in reading this article I remembered a good video I found on YouTube. https://www.youtube.com/watch?v=ei79Y_aqrm0 . This is the most relevant but there are similar animations elsewhere too. Mathematica maybe?
I could have sworn there used to be a great animation on this page. — Preceding unsigned comment added by 2600:1700:BA69:10:2235:9EF3:37E4:4EAE (talk) 22:23, 3 August 2022 (UTC)

- https://www.wikidata.org/wiki/Q1139169 here's one on wikipedia. Can we add it to this page? Ionsme2 (talk) 15:43, 9 April 2023 (UTC)
Which?
[edit]In the top section, the article claims that the herpolhode is a closed curve, but in the third? section, it says that it's generally open. 80.229.247.11 (talk) 00:17, 1 April 2024 (UTC)
