BZZZZZT! - 92.5 is a percentage, not a ratio (the percentage by weight of silver in sterling silver). The corresponding ratio (silver to non-silver by weight) is 37:3.

I believe the correct ratio for Sterling Silver is 0.925/0.075 =12.333 or 37/3

There is also Britannia Silver which is richer and has a ratio of 23.04 or 599/26

 2021-12-14, 23:48 #15 Dr Sardonicus     Feb 2017 Nowhere 537410 Posts Lo, these many years ago, I had a real-life encounter with the "silver ratio." I lost. My high school geometry teacher refused to give me credit for a compass-and-straightedge construction I had devised which was for one of the numbers $1\;+\;\sqrt{2}$ (the "silver ratio") or its inverse, $\sqrt{2}\;-\;1$. (I don't remember which it was, but it was one of them.) My construction was correct, but it wasn't the one he had in mind, and he didn't understand my reasoning. (I did, however, manage to pass the course...)

The authors of the physics paper derived their numerical result without noting this association. If asked I'll try to dig up that paper. The UPC is a measure of distance whereas the UHC is a measure of area. Last fiddled with by jwaltos on 2021-12-15 at 02:40
