💁🏻‍♀️ TIL: 🐵🔺 Researchers at #CarnegieMellon tested geometric shape matching in #monkeys, #children, and #adults with little formal schooling. Both monkeys and preschoolers relied on intuitive reasoning, while educated adults used symbolic tools. The results suggest geometric intuition is shared across #primates and refined through #learning. 👉 https://www.sciencealert.com/monkeys-have-geometric-skills-on-par-with-human-preschoolers-study-suggests #primates #geometry #cognition #science #math #education #animals #intelligence #psychology

The Only Thing Separating Monkey Geometry Skills From Ours Might Be Formal Education

If you've ever gone hiking and reached a fork in the trail, you may be confronted with two triangles: one pointing right, one pointing left.

Scale[s]. Xiqu Centre in Tsim Sha Tsui, #HongKong, back in March. I'm delighted to announce that I'm one of the Selected Photographers for the Urban #Photo Awards 2026 in Trieste, Italy! And the competition received a staggering 20,000 submissions! Five of my works have been published in their gallery: #Architecture #Design #Geometry #Travel #TravelPhotography #FotoMontag #PhotoMonday #ShotoniPhone #MobilePhotography #Photography #UrbanPhotography #Urban #City #Cityscape #Building

A Very Cool Thing: This #astrolabe is from Seville, made in 1224 AD (Oxford, HSM inv. 50934). On the "throne", at the top of the instrument (usually in astrolabes from the Islamic world), note the #geometry diagram: it shows the method for drawing the perpendicular bisector to a segment (with a fixed compass), used here to draw the astrolabe's meridian line. The maker engraved it like an emblem, offering us a glimpse into their process…

Happy birthday to autodidact #mathematician Alicia Boole Stott (1860-1940), shown here with diagrams of cross-sections of 4D polytopes from her publications. Alicia came to math honestly. Her father Prof George Boole developed Boolean logic, but died when she was 4. Her mother Mary Everest Boole was an autodidact mathematician & innovative math educator, who taught kids math through manipulation of objects. 🧵1/5 https://minouette.etsy.com/listing/4459151187 #womenInSTEM #histsci #mathematics #geometry #mastoArt

There is a perfect storm of circumstance pushing me back into doing #Woodworking and I'm going to build a crosscut sled, to facilitate a couple of other projects on the go. Also the not-cast-iron top of this new table saw is a bit not-perfectly-flat, making it difficult to actually calibrate it to the 90 stop - the sled will span the whole tabletop, so should average out to something serviceable. I ponder taking it back and getting the one I see in the youtubers' shops (the ones who don't have Sawstops that is), but that's another $aintgot cause this is a cheaper saw that was on sale. And it's pretty darn good nonetheless. And the Worm motors have a kind of 50s vibe to their design, both this and my Makita circ saw, they look like old muscle cars kinda, and that pleases the small boy in me that played with Hot Wheels cars, and never will get to own that Nova with the gurgly rumble. Nor a 34 wagon Oldie But A Goodie. Perhaps an EV conversion, which will still be fun. I do miss that cast iron top. I don't miss how much floorspace I had to give up for it. I dunno. Anyways. So I was comparing sled designs among my favorite youtube woodheads, I have the urge to deluxe out on everything, but decided to take the advice of this guy, who counseled starting with a simple thing, and I know that is sage advice. I have wood and supplies all at hand for that, so I can have it done in a few days without having to shop or do any fancy routing. But anyways, folks who are into #Geometry and who work in #3D stuff will find this exercise in risky saw abuse fascinating, and you will also be happy that he has done the experiment for us, and when you need a complex curve dug out of a piece of wood, you will use an appropriately-shaped router bit on the router table, rather than turning your woodshop into a Jackass set for the views. But let's give him views anyway, the nutjob...
