  • ... that the principles of quantum mechanics have been demonstrated to hold for complex molecules with thousands of atoms? Source: "... we report interference of a molecular library of functionalized oligoporphyrins with masses beyond 25,000 Da and consisting of up to 2,000 atoms, by far the heaviest objects shown to exhibit matter-wave interference to date. We demonstrate quantum superposition of these massive particles by measuring interference fringes..." ([1])

  • New GA, promoted 22 March (2 days ago), plenty long enough, and meets policy (except for the last sentence in history - more modern history than 1930 is needed, but in a bit more detail and with references! And there are some other unreferenced bits that could do with improving in the future, e.g., at the end of the mathematical formulation first part, but I don't think that's needed for this). Hook is referenced, and is interesting - although possibly there are more interesting hooks you could pull out of the article. No QPQ needed (1st DYK). The big problem, though, is that the article was on the main page as a Featured Article in 2004, I need to double-check with others that this is allowed. Thanks.

    • Asked at Wikipedia_talk:Did_you_know#DYK_that_was_formerly_Today's_Featured_Article?. Thanks. Mike Peel (talk) 18:58, 24 March 2021 (UTC)
    • If you have other suggestions for the hook I'd be happy to hear. As for the history, yeah, it should be expanded. One should be careful not to confuse it with quantum field theory, QED, QCD, etc., but there were plenty of interesting developments on the basic non-relativistic quantum mechanics.

      • @Tercer: It's up to you to suggest alt hooks if you want. No problems with the history needing to be expanded, but that paragraph (and probably the others) should be referenced - looking again at Wikipedia:Did you know/Reviewing guide it says 'A rule of thumb for DYK is a minimum of one citation per paragraph, possibly excluding the introduction, plot summaries, and paragraphs which summarize information that's cited elsewhere.'. Thanks. Mike Peel (talk) 19:56, 24 March 2021 (UTC)
        • I'm not going to start randomly inlining citations because of some arbitrary rule from DYK. The article is well-sourced. I removed this particular paragraph in any case, as that subject was better covered elsewhere in the article. Tercer (talk) 23:00, 24 March 2021 (UTC)
          • @Tercer: Thanks for removing the paragraph, but I hope it can be added back later with much more info. It's generally a good idea to include inline cites - if it was a paper introduction then they would be expected, it's not an arbitrary rule for DYK. So now, the main issue is whether this is OK given the past FA appearance - I expect it is, but let's wait a little to see what others think. Thanks. Mike Peel (talk) 23:11, 24 March 2021 (UTC)
