Ugh Apple maps has ads now. Thats a slippery slope

Phonopolis by @amanita-design.net is the best game I’ve played since animal well

Regrettably, I now have a twitter account x.com/shirazkn?s=21

What's the most surprising fact you've learned in the last couple of weeks? I don't mind if it's quite technical. I just want to hear what you folks are being surprised by!

2. Whether or not this email was indeed AI-authored, it's worth taking a moment to reflect on why we write, where authenticity matters, and what happens when we use LLMs as communication surrogates to express our thoughts (or the thoughts think we are supposed to express) for us. From our course:

You may have heard that the Banach-Tarski paradox is a consequence of the group of spatial rotations SO(3) having a subgroup that is free on two generators. But what does that look like? Answer: Roughly like this! kyleormsby.github.io/F2-in-SO3/ 1/n 🧮

I've been working on the research side of this embodiment!! There's very few workplaces in the US where you gotta navigate a robot maze to get from your desk to the coffee machine

Highly, *highly* recommend The Artisan of Glimmith (and not just because I made a few puzzles for it). I talk a lot about the beauty of logic/pencil puzzles and this is one of the most accessible ways to see it! store.steampowered.com/app/4160210/...

OpenAI head of robotics just resigned over company deal with the Pentagon saying… “Surveillance of Americans without judicial oversight and lethal autonomy without human authorization are lines that deserved more deliberation than they got”

The long term economic bet seems to be keep general economic output relatively the same, automate with AI, replace workers and cut costs. How does that not just drive the price of everything to zero. The whole economy is people doing things for other people, I'm going insane.

Just found out Fredrick Brennan died. I only met him in person once, but I always had a lot of respect for his personal growth and ownership of his past. More than anything, I respected his commitment to changing himself for the better. He was a good guy. So it goes.

Finally had a chance to play Ooo. The difficulty ramps up much slower than other puzzle games of this genre but this game is NOT fuckin around lol

Building solar farms over bodies of water to cut evaporation and generate power

Work tasks today included thinking about a magic trick and Catalan numbers at the same time — living the dream!

This is why I love math btw

Not very urgent compared to some things, but okay: On MathOverflow I asked what has been done to make this question-answer website more welcoming to women: meta.mathoverflow.net/questions/63... Answer: something once, but nothing now. But some preferred to argue against the very question. (1/2)

Thoroughly enjoying this article by John Baez and his friend that gives control theory a categorical treatment arxiv.org/abs/1405.6881

Massachusetts has lucemass.org! Stay safe ❤️ #massachusetts #boston

@skatestory.com is sooo fire I feel like I did the first time I played need for speed or burnout as a kid 🥹

Outlook for mac comes configured with a default "Get Outlook for Mac" signature.. I want 30 minutes in a room alone with whoever thought that that was a good idea

ahah IT WORKS look it's a C² dual quaternion B-spline!! this is interpolating *poses* in dual quaternion form, coupling position and rotation, instead of treating them independently (this is a really neat thing!!)

It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick. Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.

This blog post connects the "monogram notation" introduced by @russtedrake.bsky.social and widely used in #robotics and #graphics with concepts from Lie groups (e.g., left-/right-invariant velocities) shiraz-k.com/posts/roboti...

Started a new blog post on Principal Bundles at www.shiraz-k.com! It's a long way away, but I'm excited about how this illustration turned out: #MathSky

Relying on LLMs when we have specialized tools for tasks... it's so lazy! The best AI applications are specialized models (eg drug discovery machine learning, handwriting recognition vision models for sorting the mail) used for specific tasks. LLMs are not generalists!

Python was awarded a funding grant, funding grant asked Python foundation to remove all diversity and inclusion initiatives they have. Python foundation said no and rejected the grant. If you use Python, send a few dollars to the charity to keep it going. I’m pushing a dono on behalf of ScamGuard.

My version of this - I called it Dirac's Belt Swimming in Dirac's Sea :) Inspired by Roger Penrose's book The Road to Reality. Watercolor and acrylics #SciArt #MathArt #PhysicsArt Math brackground (plus early sketch of this) in this blog post of mine: elkement.art/2021/02/15/d...

#mathsky tip, if you're on MacOS consider getting Alfred (blazing fast drop-in replacement for Spotlight without AI bullshit) and set it up so that "w <search_term>" directly pulls up the Wikipedia page! Only downside is that you seem to have to spell the page exactly right. @alfredapp.bsky.social?

"Misuse as a Use of Language" from Jan 2023. Having fun reading my own writing, because back then I had soo much motivation to introduce the uninitiated reader to 20th century mathematics. This post leads into Gödel's incompleteness theorems.. shiraz-k.com/posts/langua...

‘96% of healthcare professionals said the model helps to reduce children’s anxiety, and 46% reported a lesser need to use sedation after the children played with the set.‘ ‘Lego doesn’t sell the sets and instead has donated more than 10,000 of the kits to hospitals around the world.’

Spent a lot of time today playing around with @diffgeom.com's incredible math visualizations www.diffgeom.org/software/ind... My favorite was the Torus Sketch! Makes me wanna learn Javascript

They call it a window because it keeps the wind owt

@skatestory.com is just incredible on all counts. Dude has been developing it for as long as EA has been developing their silly fortnite reskin

New blog post! Through a sequence of images, I verify that the unknotting number of the connected sum of a (2,7) torus knot and its mirror is less than 6: I show that this first image is the connected sum, and after changing those crossings, it produces the unknot! divisbyzero.com/2025/10/08/t...

I love math

The Sora tiktok product is so disgusting on so many dimensions. What kind of sane organization uses hundreds of millions of dollars not to improve human welfare but to steal art in order to replace artists. Imagine all the ways that money could have otherwise been used.

Visited Emmy Noether today at Bryn Mawr PA! Here’s a lovely plaque that has inscribed on it her famous Noether’s theorem from physics and the defining feature of a Noetherian ring

The mean of N points is sum(points)/N, but their median (known as the Fermat point in the N=3 case) is surprisingly difficult to compute! The deviation between the two increases with the asymmetry of the triangle. When one of the angles is >120° the median clips to that vertex~ #mathober

Each pair of circles is interlocked in what’s called a Hopf link. Each point on the sphere corresponds to a circle up above (sitting in dimension 4, visualized here in dimension 3). I move a set of points on the sphere to look at all the circles sitting above. #mathtober
