https://phys.org/news/2021-08-secret-stradivari-violin.html New research co-authored by a Texas A&M University scientist has confirmed that renowned violin maker Antonio Stradivari and others treated their instruments with chemicals that produced their unique sound, and several of these chemicals have been identified for the first time. Joseph Nagyvary, professor emeritus of biochemistry at Texas A&M, who first proposed the theory that chemicals used in making the violins—not so much the skill of making the instrument itself—was the reason Stradivari and others, such as Guarneri del Gesu, made instruments whose sound has not been equaled in over 200 years. An international team led by Hwan-Ching Tai, professor of chemistry at National Taiwan University, has had their findings published in Angewandte Chemie International Edition. About 40 years ago at Texas A&M, Nagyvary was the first to prove a theory that he had spent years researching: that a primary reason for the pristine sound, beyond the fine craftsmanship, was the chemicals Stradivari and others used to treat their instruments due to a worm infestation at the time.

It make quite some waves when it came out (I do not have access anymore), and there is a book on this matter titled "The Afghanistan Papers: A Secret History of the War". A couple of excerpts and comments from reviews:

I don't think it does that (the so quickly part) but +1 for the link. We had a relatively smooth (World Wars notwithstanding, since they were on the same side) transition from British to American World hegemony but he seems to have a grasp of the American's workings of it, and why they probably can't maintain it. (OT, but his video with advice for anti-vaxxers is also pretty good)

Good analysis here of why the government collapsed so quickly. https://www.youtube.com/watch?v=AI7FTx2_lB0

And if they looked more like this, we'd save a lot of street surface for pedestrians, especially if they looked more like this. And put to better use - the parking lots for all those extra people we never know where to put and the driveways to make fresh food. It's not as if people hadn't been thinking about these problems!
