It looks like the ⍼ saga has finally ended!
The unicode character '⍼' was a mystery first noticed in 2022: https://ionathan.ch/2022/04/09/angzarr.html. It's in the Unicode standard as a mathematical symbol. But no one could find any examples of it having been used, and no one knew what it represented. It was like the only record of an extinct species, fossilized in the Unicode standard.
But now someone has found the document it originally came from! It represents the angle 'Azimuth', and the symbol probably comes from the path light takes through a sextant. https://ionathan.ch/2026/02/16/angzarr.html
(@johncarlosbaez might appreciate this symbol!)

@OscarCunningham @johncarlosbaez I'll have to check my sextant's manual to see if it's in there!

@OscarCunningham @johncarlosbaez Il seems to me Beth. In cantor transfinite theory, that is together with Aleph.

@olasd @OscarCunningham @johncarlosbaez the part about sextants being used for measuring azimuth is odd -- you almost never use them horizontal and would use a transit to instead.

@OscarCunningham @johncarlosbaez Oh that's really neat.
It looks very much like the Linking Sigil "Ellis", used in some modern spiritual/magical practices.

@olasd @OscarCunningham @johncarlosbaez if you are in the 1800s and can't afford fancy chronometers, you might measure the distance from the sun to the moon with your sextant to correct your inaccurate clock, but that's the only time I've done anything other than vertical height angles.

@OscarCunningham @johncarlosbaez Sorry, but this is absolutely not solved. The source listed is a register of symbols, not natural usage. Where did _they_ get it from in 1950? How is it better that it showed up magically there, instead of in unicode directly?

@pianosaurus That's true. But it's a big improvement just to know what meaning that register assigned to the symbol!

@OscarCunningham Absolutely. I picked up on the wikipedia edit a few months ago (someone linked it here on Mastodon), and got my hopes up when I saw this now thinking it was more news. Hopefully, the buzz generated around it now will end up uncovering some more info.

@OscarCunningham @johncarlosbaez Makes me wonder if there's a group of people out there nodding their heads say, "Yeah, I'm so glad that's included-- I use it all the time. Of course, the average person would only use it every couple of years or so."

@OscarCunningham @johncarlosbaez cool! I stuck it in my username when I learned about it and now I'm keeping itn!

Nel frattempo qui c'è la copertina e la colonna sonora della puntata che accompagnerà come sigla finale i commenti di quelli che vorranno commentare.

Vorrei fare una edizione speciale referendaria del mio podcast. per motivare i 51 ascoltatori a coprire correttamente il tragitto da casa propria alle urne: potete chiamare per favore il numero +39 0510827854 e lasciare un messaggio nella segreteria vocale spiegando le vostre ragioni per votare NO? Trasmetto tutto integralmente. Non c'è bisogno di grandi elaborazioni intellettuali, bastano anche impressioni soggettive del tipo "mi sono convinto che votare SI porterebbe sfiga a tutta la nazione"

@nuclearpasta it is, but in the longer term it's truly beneficial
