My PhD thesis "Quantum State and Unitary Complexity" is out: cs.toronto.edu/~rosenthal/the….
Three reasons to look at it even if you're already familiar with my papers:

@captgouda24 See e.g. quantamagazine.org/mathematics/ for explanations of research-level math to a general audience, or @3blue1brown" target="_blank" rel="nofollow noopener">youtube.com/@3blue1brown for more undergraduate-level concepts.

@captgouda24 One way you know it's not like philosophy is there's never been a Sokal affair for math.
English
Folks, obscurity is not a virtue. It may be inevitable, it may be necessary, but it is not a virtue. This is getting a lot of replies rejecting the notion that we should try to help people understand things. It's like philosophers -- they have mistaken obscurity for profundity.
Nicholas Decker@captgouda24
@dimschko No, it needn’t. Things should be arranged pyramidically, starting with motivation, then a broad verbal description of what we are doing, then attacking the problem with increasing formality, then connecting it to other problem in the literature. This is how econ does it.

@PensareBBall My basketball IQ isn’y high enough to see the problem with this shot. Open 3 while two Nets players are in the paint seems fine?
English
Immanuel Quickley - Fined $25,000 for shot selection detrimental to the team.
English
@PensareBBall Quickley needed to move to the corner so Ingram would have a clear pass to Scottie.
English
Tell me what's wrong with this sequence. Forget about the miss.
English
@PensareBBall I wonder why Darko doesn’t replace RJ in the starting lineup with a three point shooter like Ja'Kobe or Gradey (while still playing RJ starters’ minutes). Is it just because preseason is the best time to experiment?
English
This was a really bad possession. To be fair to my childhood, good teams in the early 2000s didn't space this poorly. This possession would have been an immediate timeout from Phil, Pop, Riley or Adelman. So basically we're the Bobcats right now.
William Lou@william_lou
raptors starting five really gotta work on their spacing. havent seen offense like this since the early 2000s.
English
@robbensinger At least in setups I’ve seen, in Prisoner’s Dilemma you screw over another person by defecting, whereas in Newcomb’s paradox the boxes just sort of materialize out of nowhere.
English
It's funny how everyone thinks of the Prisoner's Dilemma as "bog-standard dilemma, you're a dick if you defect" and thinks of Newcomb's Problem as "insane paradox, one-boxing is crazy", even though they're literally the exact same problem and two-boxing is identical to defecting.
English
If Collin Murray-Boyles ever figures out how to shoot consistently he's a top 4 pick in every 2025 redraft. I'm assuming the Raptors are banking on this outcome as a matter of if, not when.
English
@PensareBBall And I expect they’ll be even better in future years, with their youth and draft picks. I worry that the Thunder might single-handedly prevent the Raptors from winning a championship in Scottie’s prime.
English
The OKC Thunder are sending a message to the NBA world.

@goblinodds @LexerLux It takes about n*log(n) friends to cover n days.

i'll stop making new friends once every day of my calendar is occupied w someone's birthday

@Benthamsbulldog Agh, I’m visiting the US while you’re visiting the UK.

I'll be at the EA student summit in London tomorrow. Come say hi!

todo if/when moving to nyc:
- hang out w all the twitter people
- figure out if there's a good shipping container port to ogle
- find the bit of the music scene i'd enjoy

@esrtweet @PstafarianPrice I’ve tried and failed to enjoy cooking for myself, and I’ve lived my adult life in small studio apartments with little room for guests. So as with any other good or service in a capitalist economy, I’m happy to pay someone with a comparative advantage in cooking to do it for me.
English
@PstafarianPrice This mystifies me. Cooking for my friends and family is a pleasure. Why people would give this up to entirely eat food cooked by strangers, I just don't understand at all.
English
We're culturally falling out of the habit of cooking food for friends, family, neighbors in unfortunate situations because food delivery exists but the insane prices of it make it MORE NECESSARY THAN EVER
Chris McCallister@virtuous_rogue1
@PstafarianPrice I pulled my back last weekend and was hardly able to move. I figured this would make it morally acceptable to have food delivered. I ordered from a place a block away and between delivery fee, credit card fee, taxes, tip, etc. it was $48. Next time I'll just crawl somewhere.
English
@ArmandDoma @asymmetricinfo Maybe because he seems more focused on economics than on culture-war issues?
English
something I’ve never quite fully understood is why Bernie is nationally much more popular than any of his fellow ideological travelers. AOC, Omar, Warren, etc all poll pretty terribly. I have guesses but no solid answer
English
@goblinodds I live in Cambridge (UK), happy to meet up if he’s ever in the vicinity.
English
one of my dearest friends is in Europe for the next few months and i'm not sure which of you guys might be in the area who'd be interested in meeting him?
he'll be based in Stuttgart but hopping around Europe quite a bit (and fairly able to travel on weekends)

@QuantumMemeing Presumably there’s someone at the conference who you can report this sort of harassment to?
English
no snacks in the QIP breaks?!?!!!!
what am i, an animal?

@SarahTheHaider Adding tomboys to male-only groups never changed the vibe when I was a kid, except for conversations about sexuality at a certain age. Out of curiosity I looked at the replies to see what specifically I’m overlooking, and was disappointed that no one even tried to explain this.

Single-sex bonding opportunities are wonderful, actually, and should be enjoyed by both sexes.

There is no backtracking now. He already shown his daughter what he thinks of her.

@razibkhan I think people who self-select into pure math rather than physics tend to be less interested in the external world to begin with (and more generally, less interested in problems that aren’t precisely defined).
English
@windyneoneocon @noampomsky Same. This caveat is too big for me to answer the poll.
English
@noampomsky Most of them, with a caveat - there are other ways to make oneself unattractive, such as wacky hair, body piercing or tattoos.
English
ok everyone in the comments is saying every dude is this way but I polled some guys and average seems more like “I find 25% of women my age who are in shape attractive”
Ava@noampomsky
my friend finds basically every girl his age who’s in decent shape attractive. this actually seems like the ideal way to be wired?
English
@esrtweet @Anthrofuentes Apparently many of these pitches included a then-obligatory sentence about social justice despite the project having nothing to do with that: astralcodexten.com/p/only-about-4…
English
@Anthrofuentes No sympathy. Anybody with "social justice" in their pitch deserves to be permanently defunded, living under a bridge, and thanking their luck that they weren't thrown out of a helicopter.
English
My colleagues and I are on the hit list for having "social justice" in our project-a successful project supported by a professional organization & used as a model by others. Scientists must work together to push back & Institutions must support them commerce.senate.gov/2025/2/cruz-le…
