Mathematicians’ new best friend? ~ Benjamin Skuse. https://scilogs.spektrum.de/hlf/mathematicians-new-best-friend/ #AI #Math
The prompt for day 3 was 'Polyhedron'. In mathematics a 'convex polyhedron' is any subset of ℝ³ which can be obtained as the convex hull of finitely many noncoplanar points. However, when convexity is not required the definition of 'polyhedron' is in some dispute.
Certainly every convex polyhedron is a polyhedron, however there are multip-
On second thoughts, this post would be better expressed as an alignment chart meme.

Math hivemind: I'm looking for something on the mathematics of kumihimo braiding.
The version I know of has a disk with 8 slots, and you start with 7 strings in slots. You take one of the strings, pull it out of its slot, and put it into the empty one, and repeat. It's a super simple way to make a nice braiding pattern.
See this for pictures: https://raft.net/wp-content/uploads/2020/08/PGS-Kumihimo.pdf
The person who showed this to me told me which number of strings worked, but I forget what she said. If you just try to do the same thing with, say, 5 strings -- make 6 slots, pull up a string two slots from the empty one, put it in the empty one, repeat -- it didn't seem to work. So it's not just 2 being relatively prime to 5 or 7.
Anyone have any links or resources on this?

I have a #science question. A major challenge in #climatology and climate models is reconstructing historical weather and climate data from incomplete and fragmentary data sets and many different sources. I know that there is a lot of thought put into these models, and that they largely do it well. But to outsiders, this process of reconstruction can often seem dubious and thus is frequently used to cased doubt against both these reconstructions and the field of climatology as a whole.
So what I could use for such discussions are other examples of mathematical reconstructions of historical datasets from fields _outside_ of climatology, to show that this is not a unique process but a widely used approach. Can anyone give me any suggestions?

Happy Pythagorean Triple Day, to those who celebrate.
Pythagorean triple?
3² + 4² = 5²
9 + 16 = 25
Today is 9/16/25 (at least in the US).
Happy #PythagorasDay! 🥳
Today’s date is 9.16.25, or 3² + 4² = 5².

I know some of you have probably just been out of your minds in anticipation for this year's Mathober prompts.
Well - I broke out the random number generator, word list, and honed in on my curation energy and delivered.

I was in my early 40s before anyone told me that “if you want to be a girl, you can just be a girl.” So I did.
But no one was very told me I’d need an advanced degree in topology to understand how women’s clothing works!
