Then they just leave. <a href="https://infosec.exchange/tags/audhd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#audhd</a> PS. You can. (LOL thanks for staying? ) -make a loop. -bisect twice to get 4 equal segments. 1/2 * 1/2 -trisect one segment 1/3 -move one trisegment length to one side, then other two to the other -stretch points on flat surface, you now have a 345 unit triangle of arbitrary perimeter length. 1U* 1/(2x2x3) = {StringLength} StringLength = 12U (arbitrary.)OR: -trisect the loop, then bisect twice one trisected length. 1/(3 x 2 x 2)unit. -move one quartered segment to the left.from a string and a surface!<a href="https://infosec.exchange/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a>

Alejandro Gaita-AriñoOK, and now a puzzle/quiz for the <a href="https://scholar.social/tags/symmetry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#symmetry</a> (point group) oriented people. What is the label you would associate to an object we are seeing, somewhere in the picture?A clarification (?) for the non-magnetochemists: it's a popular arrangement for the first layer of atoms around the magnetic ion in lanthanide-based single ion magnets (LnSIMs). Popular because it was present in the first family of LnSIMs, and also because it's rather stable, chemically, so it's common.<a href="https://scholar.social/tags/chemistry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chemistry</a> <a href="https://scholar.social/tags/physics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#physics</a> <a href="https://scholar.social/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a>

M. Vice Pres commandasaurus 🦖“Mathemalchemy” has been described as “a mathematics fever dream turned artistic playground for all math lovers (and haters, too).”It is a fantasia fabricated in beadwork, ceramics, crochet, embroidery, knitting, leatherwork, needle felting, origami, painting, polymer clay, 3-D printing, quilting, sewing, stained glass, steel welding, light, temari, weaving, wire bending and woodworking. Last year it had an extended stay at the National Museum of Mathematics on Fifth Avenue in New York City, where one visitor on opening night felt a “Grimms’ fairy tale vibe.” The project’s official catchphrase is: “Mathemalchemy, where math is transforming.”<a href="https://www.nytimes.com/2025/03/14/science/mathematics-daubechies-mathemalchemy.html?unlocked_article_code=1.4E4.0CwS.uiqPgmhFhpQw&smid=url-share" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.nytimes.com/2025/03/14/science/mathematics-daubechies-mathemalchemy.html?unlocked_article_code=1.4E4.0CwS.uiqPgmhFhpQw&smid=url-share</a><a href="https://hachyderm.io/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://hachyderm.io/tags/art" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#art</a>

NovaMathy people often look down on crochet due to misogyny or minimizing of the arts (math is a male dominated field BTW) , but crochet should not be gendered let alone demeaned because it's associated with female crafts. Crochet is not just able to be applied to math, but is inherently mathematical. To make anything in crochet at minimum you need to be counting and planning what you are doing. You can use math to plan out specific shapes and to understand what process you need to follow to make that shape. Making something in crochet is making something with one string (usually) so it is a very complicated mesh. You can make complex images using a pixel grid sort of style. You can also leave the flat "2D" creations and move in 3 dimensions. Using math, you can make things ripple or have waves or be flat, or stretch, or whatever. For example, you can crochet hyperbolic shapes: <a href="https://m.youtube.com/watch?v=xtlDND7NVp8" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://m.youtube.com/watch?v=xtlDND7NVp8</a> <a href="https://techhub.social/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://techhub.social/tags/crochet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#crochet</a> <a href="https://techhub.social/tags/engineering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#engineering</a> <a href="https://techhub.social/tags/geometry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geometry</a> <a href="https://techhub.social/tags/hyperbolicgeometry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hyperbolicgeometry</a>

Simon Tatham<a href="https://hachyderm.io/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematics</a> question: is there any good collection of all the knowledge about Conway's "nimbers"? I've found any number of beginners' explanations, but nothing further.(I mean the thing that makes a field of characteristic 2 out of ℕ₀, with addition corresponding to bitwise XOR, and multiplication a really weird inductively defined thing, such that every initial segment of ℕ₀ of size 2^{2^n} forms a subfield.)I was idly playing around with them recently – wrote a tiny Python thing to implement their multiplication. I happened across the fact that in each of the first nine of those finite subfields, the _largest_ integer in that subfield – 2^{2^n}-1 – generates its whole multiplicative group. That is, 3 has order 3, 15 has order 15, 255 has order 255, … up to and including 2^512−1.Is that true for all n? I'm curious to know if this is a known result, or at least a known conjecture. Seems to me it would be pretty neat if it were true, because it would give you a "canonical" choice of primitive polynomial over GF(2) of degree 2^n – just take the min poly of the corresponding nimber.By my calculations, the first few of those polynomials (in the usual binary representation where 2^n stands in for x^n) are 3, 7, 25, 425, 101021, 7158330089, 27971386341277386797. But OEIS doesn't know that sequence, so maybe this isn't known?<a href="https://hachyderm.io/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://hachyderm.io/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#maths</a>

Ian Kluft ✈️🎈🌋<a href="https://avgeek.social/tags/PiDay" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PiDay</a> is celebrated in the United States on March 14 because the US date format 3/14 looks like the number pi 3.14 (and as many more digits as you need/want). The tradition is to celebrate with a slice of pie🥧. Although the definition is flexible enough to include pizza🍕 as a pie if you want. Techies may use the day as an excuse to experiment with a Raspberry Pi computer.
