A helix formed by gluing together regular tetrahedra.

A helix formed by gluing together regular tetrahedra.

Coxeter noticed that you can stick regular tetrahedra together to make a helix. It never repeats: no two tetrahedra have the same orientation in space!

These simple discoveries are priceless.

I canโ€™t find scratch calculations lying around, but these 2014 maths lecture notes and these notes from an Assyriology conference last year are probably quite heinous tooโ€ฆ (At the Assyriology conference my converter was broken so I was refilling every 15 min, though I donโ€™t think thatโ€™s visible.)

Right, I have noticed that it seems unusual/fancy to non-French Europeans too, whereas to me itโ€™s just the only thing I write with (and Iโ€™m hardly serious about handwriting, most of this is ugly scribbles that I can barely read a few days later).

I am always surprised that people donโ€™t use fountain pens at school, in France it was mandatory (and Iโ€™m 32), but apparently thatโ€™s not the case in other European countries.

Certainly I very much dislike writing with a ballpoint compared to a fountain pen.

Surely we also need more Sumerian content on Bluesky, so this seems as good a time as any to post this Blue Suede Shoes cover: www.youtube.com/watch?v=2gCe...

I wish Iโ€ฏcould say I typed this from reading the tablet, but my OB cursive is abysmal so this would have taken me ages; I read ๐’€€๐’ˆพ ๐’ˆ ๐’•๐’ด (ana madaฬ„tim, and even there Iโ€ฏwas helped by @moudhy.bsky.socialโ€™s translation โ€œabout many thingsโ€) and then looked it up, finding transliterations and translationsโ€ฆ

Since neither eBL which @moudhy.bsky.social linked nor CDLI linked from eBL have a transliteration, and since this seems like the kind of nerdery you might enjoy, the relevant passage reads

On the right of the image is a sheer cliff face marked with vertical striations; talus lies at its base. The left of the image is in almost total darkness, and the background is deep space.

On the right of the image is a sheer cliff face marked with vertical striations; talus lies at its base. The left of the image is in almost total darkness, and the background is deep space.

This is a cliff on comet 67P/Churyumovโ€“Gerasimenko.

It's about 1 km tall.

If you jumped from the top, it would take you 47 minutes to reach the bottom, and you'd probably be OK.

Okay, this is the very rare Substack post that's worth loading the Nazi newsletter site for. I am *incredibly* surprised I kept about 90% comprehension until I hit the 1100s.

It can be tricky to accomodate the things people do in real orthographies within the confines of the sacrosanct stability policy and similar concerns. See, e.g., the Background discussion of ยง2.1 in www.unicode.org/L2/L2025/251..., featuring ยธ used as a letter.

Character Encoding Stability Unicode Character Encoding Stability Policies

Of course there are many other commandments on the tables of the Stability Policy www.unicode.org/policies/sta...

Thou shalt not unmake a case pair, nor make a case pair out of pre-existing characters (so the full uppercase of รŸ must never become แบž, no matter what the Germans do with it).
