ok idk what happened today, I was bored I guess. Watch me seamlessly go back to 5 non-reply posts in half a year now; gn.

kinda interesting story here. Can a LLM with some vibecoded framing produce a decent index for a book? I confess I wasn't aware of indexing as a profession prior to this, but even without leaving this site you can find the tail end of a community, with orgs, conferences, meetups..

no matter how you slice it, if intelligent life survives all other hurdles, it will eventually end for astrophysical reasons, be that the expansion of the sun or cosmic heat death. It will be like climate change but worse: much slower, much more predictable, not preventable, hopelessly unsurvivable

to point at an elephant, it is incredibly obvious that the long-term global "cost" of basically ending extreme poverty is super-duper negative

Have known the evenings, mornings, afternoons, I have measured out my life with coffee spoons (TS Eliot) (The power was out at the NIST atomic clocks, presumably)

If you've ever wanted to actually watch a laser beam bounce through a light clock, AlphaPhoenix just dropped the most incredible video

Been awhile since I wrote a blog post. Anyways... why haven't quantum computers factored 21 yet? algassert.com/post/2500

THREAD: Resurgence or: How do physicists keep getting away with ignoring infinitely big things? I wrote about this back when everyone was still on twitter. Someone asked me a question and I think it's an excellent occasion to repost the thread. 1/20

obsessed with this prediction of 2025 by a 1999 4th-grader; I've read it so many times and it's complete poetry

Natural bundles are those associated to the frame bundle; spinor bundles are supernatural

Kids these days... built different

Is it just me or is user-restricted search broken?

I've had enough summer now we can skip the rest

this was accidentaly a question about eternal inflation

thought about this again recently and have a picture I'm satisfied with, I think. Suppose at some spacetime pt there is a spontaneous nucleation of a decay to a new Lorentz-symmetric vacuum. This spreads out in a bubble at the speed of light and inside the bubble there must be some hot state to

did uall know they found a geometric circle in the sky

one day I will complete a second blog post

Aaron Swartz should Also have been granted unfettered access to JSTOR tbc. Weird twisting going on here. Pls don't go to bat for academic publishers bc you don't like AI

lmao at one pt the startup CEO guy says that soon datacenters will cause '10-15 degrees of global warming', not bc of fossil fuels but bc they just pump out heat by themselves guess we've found the magical energy source of the future: datacenters

things don't look hard on video, but this was pretty hard (for me, more objectively it's around 7C). Those holds are pretty bad, esp the big ones (click if u want to watch me climb a boulder, and don't mind the screaming)

I am apparently just going to be miserable & stressed this week until I manage to Do the Task

my apartment has been getting cleaner today, which is unrelated to the hypothetical existence of any pressing unpleasant tasks that I could be taking care of

just went to the optician and it turns out my vision has worsened by a full diopter in the last year oops

there is a spoon's worth of plastic in our brains. soon it will be two spoons. then four spoons. Turning into Oil is achievable even for us

learning things on wikipedia

I've always nodded through the stimulated emission part of how lasers work but it's actually a bit strange huh

Anyone know exactly how these images depict elliptic curve isogenies? Apparently the sixth one is inseparable but what precisely am I looking at?

A sphere? oh you mean a Euclidean de Sitter space?

this is what a global field of positive characteristic looks like btw

btw if you're missing a dark mode for the firefox pdf reader, you can set up a bookmarklet that does that

do NOT sully perfectly good math with your Sexy Murder Poet philosophy 😡😡

No

Bad news: the universal cover of the connected sum of two lens spaces is homeomorphic to a 3-sphere minus a Cantor set

look it's just an odd name for a subject about knots and 3-manifolds

Here’s the Schwarzschild version of this motivational diagram 🧪🔭 #academicsky #cosmology

wow this really changes my perception of Taylor Swift

choose your fighter

I no longer understand what the word natural means

guys after carefully studying my bsky tl i'm starting to suspect things might not be on the most optimal trajectory overall

the "don't call it zombie deer"-disease has people asking a lot of questions already answered by the name

Yes, this one is indeed both brilliantly done and raw as a fresh graze. It's vitally important literature of our time that's both a kick in the guts and a vision of hope. If you read nothing else this season read this.

the idea that (physicist's) causality means complex-analytic amplitudes is honestly bonkers

nonabelian Hodge theorists:

mostly done

time to re-set this bitch

Class field theory is great and all, but seems a bit pricey

And we are repeating this exact mistake in Europe. Established parties and media have this stupid idea of the voter as a stationary target and are leaving all the shaping and moving to far right vocal minorities

Electric charge is an integer quantity in nature. It didn't have to be this way: We could imagine a world in which electrons and protons have charges that aren't precisely equal and opposed to each other. Chemistry would break! So where does this conspiracy come from? (it's topology) 🧵

Eine Rede, die Anerkennung verdient. In 1 Minute zeigt @ricardalang.bsky.social , wie man mit der AfD umgehen sollte und ja, sie spricht Friedrich Merz zurecht die Kanzlerfähigkeit ab. Hut ab vor dieser Rede!
