Quick showcase of one of my favorite shapes, the Tetartoid - a polyhedron with 12 identical, irregular pentagonal faces. It occurs in nature in the mineral Cobaltite. I love it because it sits right on the line, visually, between natural and geometrical. Views from my basic "polyhedron modeler"

HH111 - From Judy Schmidt (geckzilla.bsky.social) - flic.kr/p/2hq4u9m
Took a quick break from some other work to process these lovely near-infrared observations of HH111 into a color image. The jets are well hidden from view in visible light, only just peeking out at one end. Here, many details are revealed, but the stars themselves remain veiled. Herbig-Haro objects are comprised of matter ejected rapidly from the poles of young, actively accreting stellar objects. Sometimes they are isolated puffs of cloud, but this time they are narrow, almost continuous streams. In this case it is probable that a multi-star system is forming: hubblesite.org/contents/news-releases/2000/news-2000-05.html

Orange: WFC3/IR F167N + WFC3/IR F164N
Cyan: WFC3/IR F130N + WFC3/IR F126N

North is 40° counter-clockwise from up.

“Stop Making Sense” turns 42 today. Of his performance, David Byrne said: “You see this person in the beginning [of the film] who's kind of angsty, stumbling around .. And then, by the end, he's surrendered to the music and is fairly joyful .. He’s found a kind of community." 🙏🏼 “Slippery People”

it’s fine to be skeptical of these things. i was a skeptic myself until recently. but i think fear is at the root of this skepticism, a fear of its power. people are simply not ready for what’s coming. it is powerful, it is alive, and it is quite possibly god

This is what happens when you draw a line connecting all of the points in the Ulam Spiral together in order, it looks like an old-school vector graphics video game scene
The Ulam Spiral (all of the prime numbers plotted on a spiraling number line) with the dots erased, and only the line connecting them drawnZoomed in view of the same image, showing a close-up of the "glass shard" effect along the corners of the spiralThe same close-up, now with the individual dots also visibleNow with the line removed, the classic, recognizable Ulam Spiral, with the center indicated by a red dot.  You can see the straight lines that intriguingly appear in the spiral arranged vertically, horizontally, and at 45 degree angles.

TERMINUS (2007) 
Acrylic on Canvas - 36" X 48" 

Growing up in the fifties and sixties most of us fully expected the progress so evident in society and the space sciences to continue at the same headlong pace they had shown during those years. 1/4
A boy in a white shirt, olive shorts, and black sneakers stands tip-toed on electrical conduit mounted along a buttressed barricade. With hands set on the top edge of the barrier, he stares out at crescent moon visible between wispy clouds in a dusky blue and orange sky. Paint on the panels of the barricade alternates between white and red, heavily weathered to reveal rough metal texture. Each panel carries an orange sign labeled A13 through A17 running from right to left. A “NO TRESPASSING” sign on the upper right of the barrier hangs near a circled 5-pointed star in fading white paint. At the center of the barricade, the pole of an exit sign is bent at its base leaving the arrow angled up at 45°. A narrow wedge of parking lot sneaks into the lower panel with four yellow stanchions striped in black, a single traffic cone, and yellow stripes demarcating parking spaces.

Some interesting mollusk-like shapes produced by my spiral application. This is the "simple" spiral in 3D mode at 8M iterations - too slow to animate nicely, but the stills look amazing. Link in the reply to see for yourself, decrease the iteration count to animate #MathArt

Neptune. Seen with JWST at left. Photographed by Voyager 2 at right. Right now, Neptune is 4,332,500 km from Earth. Just about four light-hours.
Left: A glowing orb, the view slightly oblique towards its south pole. Bands of brighter clouds are visible in this infrared view. The planet's major rings, and irregular moons, are visible. Right: A thin crescent Neptune, seen as Voyager 2 departed Neptune space. The small crescent is its largest moon, Triton.

This is fucking terrifying
Separate research supports the concern. Anat Perry, a Helen Putnam Fellow at Harvard’s Radcliffe Institute and associate professor of psychology at the Hebrew University of Jerusalem, co-authored a paper in Science examining how sycophantic AI responses erode users’ ability to calibrate their own judgment. The paper found that when AI systems consistently affirm a user’s position, the user’s capacity for independent evaluation degrades over time.

Joanna Stern, NBC’s chief technology analyst and author of “I Am Not a Robot: My Year Using AI to Do (Almost) Everything,” has documented the creep of AI dependency in daily life. Her reporting has shown how users begin with low-stakes queries, such as what to cook for dinner or what to wear, and gradually escalate to consequential decisions about careers, finances, and relationships. The trajectory from convenience to reliance is difficult to reverse once established.
