Spectacular sunset after our family run today!

here is what chatgpt had to say about the lyrics I wrote for my quantum computer punk song. I really like it!

Just arrived, from Penteract Press: @marianchristie.bsky.social, _Sky, Earth, Other_ @anthonyetherin.bsky.social, _The Robots of Babylon_ We just happened to be discussing poetry by constraints on the way home. Ms17, “These are such me books! How did you find them?!”

Dredged my high school & college Russian out of memory this morning to make my way through А. К. Гуц, _Хроногеометрия: Аксиоматическая теория относительности_ w/o relying completely on google translate.

Friday, November 13, 2015, Paris fell victim to the deadliest terrorist attacks ever carried out in France. Ten years later, to the day, Paris remembers and honors their memory.

@ninaelkadi.com, "People are not getting the environmental outcomes they want, and farmers are not happy with the economic outcomes, @theswinerepublic.bsky.social says. 'Nobody’s happy. So why are we going to keep doing what we’re doing here with the corn, soy, CAFO scheme?'"

Just learned a great new word from my Uber driver: tocayo [someone with your same name], maybe from classical Nahuatl, tōcāyoh.

What day will the government shutdown end? Nov 12 is 56% Ask prediction markets (L) not MSM (WaPo, NYTimes, both on R)

We're back on Thurs. 20 Nov when @snezanalawrence.bsky.social will guide us through 'A Little History of Maths.' How did our ancestors think about numbers? How was maths used to explain and understand the world around them? Where do numbers even come from? sitp.online/sitp/bedford/ #Bedford

Bemused by surprise expressed by commentariat at margins of REP losses last night, given @kalshiofficial.bsky.social prediction markets’ consistency for the last *year*, I explained @justinwolfers.bsky.social & Zitzewitz’ model www.nber.org/papers/w12200 in my Intro to Math Modeling class today.

Not really a fan of @zohrankmamdani.bsky.social, but it’s pretty great that he just started his acceptance speech by quoting Eugene Debs. #Election2025

8pm and they’ve called it for #Prop50!

Awfully proud to have published this terrific story of taking risks, making opportunities, and creating space for the wild creatures among us. Check out Sean Gerrity's debut nonfiction, Wild on Purpose, from bookshop dot org or nonprofit TorreyHouse.org/wild-on-purpose

@theswinerepublic.bsky.social, "there is abundant evidence that livestock raised in pastoral systems can be done in an environmentally benign way, at least compared to corn and soy production"

Ms17’s sketch of a diagram for a paper describing results of a project about spacetime geometry that she and another high school student have been doing with me.

John Stuart Mill, “If there were no more to be said than that scientific education teaches us to think, and literary education to express our thoughts, do we not require both? and is not any one a poor, maimed, lopsided fragment of humanity who is deficient in either?”

Almost finished off the Ramsey consumption/saving model in my Intro to Math Modeling class @ucsdphysci.bsky.social today. Funny that growth/decay rate of consumption is independent of income!

My heart rate during Ms17’s XC race this afternoon. The race started at 3:45, and I managed to cheer her on at 11 spots on the course. That’s my workout for today!

Ms17’s XC team running the Mission Bay course for their 2nd Coastal Cluster meet. Almost November … but San Diego!

Academia giving up self governance makes me so sad. I remember when Caltech used to have faculty actually interview undergrad applicants, which I think led to more outliers and quirkiness. Efficiency breeds homogeneity.

I am pleased to announce the third EER Summer School in Behavioral and Experimental Economics, 1-4 June 2026 at ISEG in Lisbon, www.iseg.ulisboa.pt/en/, with Isabelle Brocas, Juan Carillo, Michalis Drouvelis, Ernst Fehr, David Levine, and myself as instructors. Information at www.eersummerschool.org

Today in Intro to Math Modeling @ucsdphysci.bsky.social: a Ramsey model for optimal consumption & saving, w/digressions on Ramsey theory and utility theory.

Reading Frank Ramsey's "A mathematical theory of saving" as I prepare tomorrow's Intro to Math Modeling lecture @ucsdphysci.bsky.social. Apparently £5000 went a long way in 1928 -- Bliss!

My Twitter training is proving useful as I help Ms17 edit the descriptions in her activity list down to 150 characters!

Today in Intro to Math Modeling @ucsdphysci.bsky.social : dynamics of naïve & activated T-cells & IL-2: ODEs, equilibria, stability, and successful immune response. With a digression on diaeresis and umlaut!

Discussed Fibonacci groups in my first year seminar today. Showed the Cayley graph for F(0), the free group on two generators, and worked out that F(3) is the quaternion group.

Shame on the private companies that are funding Trump's ballroom

@scottcacciola.bsky.social & @kkrebeccalai.bsky.social, Rewriting What’s Possible in the Mountains www.nytimes.com/interactive/... "Jornet estimated that he had burned about 9000 calories/day, but he managed not to lose any weight. One of his secret weapons: flasks of olive oil that he guzzled raw."

the conversation we should be having is that AI is developing and will certainly displace many workers, and we should develop government programs to even out the losses and gains between workers and capitalists. but instead we argue about whether a trans person was on netflix

Just got back from the downtown San Diego protest. Huge crowd! Similar to the 60K+ we had back in June. The atmosphere was very chill. People showing up in solidarity to support democracy.

HAPPENING NOW: A MASSIVE crowd of protesters flood the streets of San Diego for a “No Kings Day” rally showing their love for America and standing up against the corrupt fascist Trump administration. look how huge it is
