@johncarlosbaez@mathstodon.xyz It's kind of 'obvious in hindsight', but I didn't know it until considering a hypothetical in a murder mystery.
Are twins the worst plot device in some stories, after time travel? (And I *like* some stories featuring twins or time travel 😆)

@johncarlosbaez@mathstodon.xyz "Identical twins do not have the same fingerprints however, because even within the confines of the womb, the fetuses touch different parts of their environment, giving rise to small variations in their corresponding prints and thus making them unique." https://en.wikipedia.org/wiki/Twin#IdenticalTwins

@christianp @JimPropp I don’t know about rules, but the tiling on the left seems to have a clear structure.
If colour is ignored, it has rotational symmetry of order 2. In fact, it’s as if the tiling on the right has been copied, split and filled with a horizontal band of two pentagons and two rhombuses.
The tiling on the right was known by Dürer https://plus.maths.org/content/trouble-five and https://mathstodon.xyz/@foldworks/112711074311119074

@ngons Thanks, recreating the tiling made me appreciate the beauty of the original design and the skill of the artisans.
Also, I found out that my original photo didn't show a big enough area, so had to look online for that -- but I found a subtly different tiling in the Bahia Palace.
I'm not sure if my recreation is correct, or an amalgamation of the two tilings, or something else instead 😆
Based on a tiling seen in the Bahia Palace, Morocco. Made using Zellige App and Affinity Designer.

A similar but different tiling in the palace? https://www.dreamstime.com/full-frame-shot-moroccan-mosaic-bahia-palace-abstract-architecture-bahia-palace-marrakech-morocco-image273419858

The windows are almost 200 years old, and the building has been listed for over 50 years, so some maintenance must have occurred.
Apparently a few other buildings have windows like this. The first one I saw years ago but I didn't know what they were, and there was nobody around to ask about them (and I can’t remember where, either 😆 )
An undulating window, Church of St Peter, Askham, Cumbria, England, a Grade II*-listed building https://historicengland.org.uk/listing/the-list/list-entry/1145271
Apparently the windows were made like this to let more light in than ordinary windows. (The listed status means that any repairs or maintenance must put the window panes back in the same position.)

@jrmgx@mamot.fr @ellane@pkm.social The AI Overview (not asked for) for the reverse image search was almost entirely inaccurate:
"The image shows a minimalist wall clock where standard hour markers are replaced with a single character or symbol repeated in different orientations.
• The symbol at each hour position appears to be the letter "L" or the number "1".
• The hands indicate the time is exactly 9:00.
• The clock has a simple, modern design with a white face and a metallic rim.
• The text "L 1 レー L" is visible in the top left quadrant of the clock face."

@GerardWestendorp@mathstodon.xyz @simontatham@hachyderm.io One way to include the other elements: use the symbol with one fewer elements. Here's three elements with two-element dots.
With seven elements, the dot could be the six-element symbol, but I've yet to find a good way to draw these.

It looks like the judge and lawyers for the class Action and Anthropic wanted an expedient solution. Some expect the class action lawyers to take 25% of the 1.5bn USD compensation.
I can pursue my own case for my work that was downloaded, but they know that's unrealistic ☹️
From the FAQ https://www.anthropiccopyrightsettlement.com/faq
"Even though Anthropic downloaded approximately 7 million files from LibGen and PiLiMi, many of those files were duplicates of works, or unregistered works, or were empty, corrupted, or incomplete files.
About 40% of the files Anthropic downloaded (approximately 3 million) were duplicates. Duplicate copies are not eligible to be in the Works List.
Likewise, works not validly registered with the U.S. Copyright Office are not eligible to be in the Works List. Many of the works Anthropic downloaded were not registered. For example, non-English works have very low registration rates. Of the approximately 4 million unique works that Anthropic downloaded, around 2.5 million were written in languages other than English. Most of those 2.5 million non-English works were unregistered. In addition, many of the 1.5 million unique English works were not registered. And even among registered works, many failed to satisfy the date criteria in the Class definition, because registration occurred more than five years after publication or after Anthropic downloaded such works.
Finally, many works failed validation tests. For example, the Works List does not include files that were empty, corrupted, or incomplete."

@johncarlosbaez To qualify, the downloaded works need to have been registered with the US Copyright Office before being downloaded.
Unsurprisingly, many authors outside the US did not register their US copyright as registration is not needed in other countries (or their publisher could/should have registered the copyright but didn't). It costs about 50 USD per work.
Copyright exists as soon as the work is created, but US registration is needed for US statutory damages. Without registration, there is a higher bar to receive statutory damages. (AFAIK, only the US requires copyright registration like this).
As said elsewhere, this case is about Anthropic downloading from a shadow library -- training AI with copyrighted works appears to be fair use, so far.
US copyright history would make an interesting (but different) post.

@rasjor@mathstodon.xyz I think Geogebra's strengths are in 2D and 3D Euclidean constructions (including inversion) but hyperbolic geometry would be beyond its built-in capabilities?
