Orphaned references in Seconds pendulum

I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Seconds pendulum's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT⚡ 17:54, 30 September 2018 (UTC)

A clock

The phrase "a clock" appears. Actually, there is more than one and they do not agree with one another. — Preceding unsigned comment added by 86.169.192.50 (talk) 14:29, 7 October 2018 (UTC)

Cut down

I've cut out a large amount of material from this article that was only tangentially relevant to the seconds pendulum. It could do with further trimming, but I hope that's the bulk of the irrelevant material now gone. -- The Anome (talk) 00:16, 9 April 2020 (UTC)

Agree, this has a huge amount of very tangentially related material. Needs a slimdown. As a matter of fact, most of this material is copied verbatim from Pendulum, where the seconds pendulum is also defined. The article could be merged into Pendulum--Chetvorno^TALK 06:49, 14 August 2024 (UTC)

Plural of word "pendulum" ?

Is "pendulums" the correct plural? Not "pendula" ??? 2001:8003:E40F:9601:4840:B3B8:967C:D001 (talk) 10:07, 27 July 2024 (UTC)

I wrote a lot of the Pendulum article. I think "pendulums" is much more common among horologists and that's what I use. --Chetvorno^TALK 06:51, 14 August 2024 (UTC)
