Happy a^2+b^2=c^2 day to all who celebrate.

When you think about it, we really should call "Tesla autopilot" vibe driving

No particular reason, but here: have a couple of church ceilings. #architecture

Behold its shadow.

Admire my CMY cube.

I've been working on a small DSL embedded in Python to compute exact (to machine precision) probabilities for small simulations. A good example is the D&D dinosaur fight whose probabilities I computed with Mathematica a few weeks ago. Now you can write your […] [Original post on mathstodon.xyz]

I would just like to say that Katie Hoody's NYTimes crossword puzzle today has an absolutely beautiful grid. Nice puzzle too! But just look at that in black and white. #nytxw

The diffusers on the new LED polyhedron (dihedral hexacontahedron, right) looked so much better than the first build that I had to print new ones for the truncated icosahedron (left). I also synced up the patterns on both builds (with #pixelblaze) and will be […] [Original post on mastodon.social]

Seriously though i’m biased because i’m a fiber arts sicko but if you want to see a c. 1500 masterpiece in paris i highly recommend skipping the mona lisa and seeing the lady and the unicorn tapestries: - way less people - rabbits - you can get like 1 […] [Original post on posts.rat.pictures]

@origami #origami When I tell people I like to fold cones and cylinders, they imagine I am folding a flat piece of paper and later gluing it into shape. And not without reason. Only a madman would make curved creases on a preformed cone. But since this is a […] [Original post on mastodon.social]

The specific page that prompted me to post about this book is the description of how the first stellation of the rhombic dodecahedron can be dissected into six congruent pieces (and, in passing, that it can also fill space)

Most of this book was written before I was born (and I'm hardly a spring chicken) but I've only just got it & I am enjoying it inordinately.

Fascinating watching this orangutan tying a knot. 🦧🪢

I can't even think about the real question here, because my brain has been short-circuited by the ‘fundamental result of Lucas’ quoted in the preamble. How cool is that‽ To rephrase it in terms that may be more accessible to programmer types, {n \choose k} […] [Original post on mathstodon.xyz]

I must find an excuse to do this in a lesson— we do this one point perspective thing on proportions— but five points are more fun.

So last week Linus Media Group, i.e. the folks behind YouTube channel Linus Tech Tips, announced a new record of having calculated 300 trillion decimal digits of pi. You can watch their YouTube video at https://www.youtube.com/watch?v=BD-AJwqzWsU. Or you can or read the blog post by Alexander J […]

W3C consensus is particularly significant given the detailed principles about user control over cross-context recognition, most commonly experienced as ubiquitous third-party tracking for ad targeting. While Google Chrome is giving up on removing third-party cookies, the W3C, with Google as a […]

Formal objections from anti-privacy ad tech providers required even longer deliberations, but have finally been addressed. https://www.w3.org/2025/05/council-privacy-principles-report.html

Publication of Privacy Principles as a W3C Statement has been a long process and represents the culmination of years of multistakeholder work on this topic: https://www.w3.org/TR/2025/STMT-privacy-principles-20250515/ In 2022 @CenDemTech welcomed the first public note […]
