I did check both Tennenbaum and Landa; they are not independent sources, but coauthors of Doubochinski, this is why I PRODed the article in the first place. Tercer (talk) 09:46, 19 April 2021 (UTC)

Regardless of it, it's a well-known experiment that's often performed at the undergrad level (see the YPT handout / Wilson). And having published once with Doubochinski in 1989 doesn't make Landa (2002) non-independent. Headbomb {t · c · p · b} 09:56, 19 April 2021 (UTC)

Is it? I did Google it, and couldn't find almost anything that wasn't written by Doubochinski or copied from Wikipedia (which was also written by Doubochinski). If it is well-known it must be under a different name. Tercer (talk) 11:20, 19 April 2021 (UTC)

(talk page watcher) I found several independent sources, have added Luo's paper as another ref, with a quote. Of course there are umpteen ways to transliterate/spell the name D(o)u b o s/c h i/y nsk i/y/ii, just to complicate searching. PamD 13:32, 19 April 2021 (UTC)

And for good measure have added the Pedersen paper too. It might be reasonable to trim the number of Doubchinski papers in the refs, but this thing is clearly written about by other independent authors across several decades. PamD 13:38, 19 April 2021 (UTC)

Now if someone feels picky, the copyright status of the two images might be dubious... unless we assume that RomanP who created the article and uploaded the image actually is one of the Doubohinski brothers? Hmm. PamD 13:45, 19 April 2021 (UTC)

Fine, I'll grant you that the pendulum itself is notable. What I'm worried about are the unpublished pre-preprints claiming that this is some kind of "Macroscopic Quantum Effect". It is not. There was an article about it, that was deleted against the objections of RomanPr. I think it's obvious that he is one of the Doubochinski brothers. Tercer (talk) 14:26, 19 April 2021 (UTC)

Yeah, there's definitely something weird here, with one of the references being right out of the LaRouche movement. This reference was, incidentally, where the pictures were clipped from. Most of the text was copied from there, too. XOR'easter (talk) 17:33, 19 April 2021 (UTC)

Good catch. I had noticed that there was something weird with that magazine, but I had no idea it was so weird. Perhaps the origin of this mess were the claims in some of the references that this pendulum somehow generated free energy. Tercer (talk) 17:59, 19 April 2021 (UTC)

Ah, that could be it. XOR'easter (talk) 20:13, 19 April 2021 (UTC)

I'll be moving this to the talk page of the article. Headbomb {t · c · p · b} 16:08, 19 April 2021 (UTC)

It would be nice if the article is renamed according to the most acknowledged/frequently used transliteration, because in google scholar Doubochinski's pendulum gives few results (12) with very few citations (avg ~3.6). I tried a few transliterations and I didn't find matches. If the name is not recognized in the literature and only used in few publications... we should not use it. --SimoneD89 (talk) 06:12, 20 April 2021 (UTC)

I think there are just not many results. With the transliteration "Duboshinskiy" I found another reference [1], but it seems that "Doubochinski" is indeed the most common one. Tercer (talk) 07:37, 20 April 2021 (UTC)
