No longer a hypothetical question: What would happen if a bunch of hype-loving investors who didn’t really understand the nuts and bolts of AI took over the world?

I asked my students last semester what percentage of the internet is pure bullshit (either intentional or accidental). The lowest answer was 90%, and the CS major guaranteed it was 99.9999%. I then asked where AI gets its answers from. The looks on their faces was the highlight of the semester

Sometimes when building a minimal reprex for a bug, you discover that you were the bug all along. I assume this is what Kafka was on about.

Just posting this picture of an iron lung at University of Pittsburgh School of Public Health, for no particular reason.

β€œI wish it need not have happened in my time," said Frodo.
"So do I," said Gandalf, "and so do all who live to see such times. But that is not for them to decide. All we have to decide is what to do with the time that is given us.”

This is not what I expect from the MAA. I agree it sounds like article was written by an LLM

The reason I prefer this is that it’s feels more natural, not a random collection of rules. Symmetry, ability to undo a move, ability to compose moves, are all very natural things to want to have/study. But the set-with-operation def seems hard to justify vs semi group or monoidβ€”it feels arbitrary

I’ve long felt that the set-with-binary-operation definition is the wrong way to define a group. I much prefer to say it is a nonempty set of symmetries (bijective functions of some set to itself) that is closed under compositions and inverses. Associativity and the identity come for free.

When I was a young man there were whispered rumors among the elders that they could remember their own elders talking about a time when getting grants had been a means for doing science, rather than vice versa.

I loved meeting up with old friends and learning new things at #JMM2025 but the lack of internet is a serious problem. Normally I can hobble along with cell service but can’t get more than one bar in most parts of the conf center. Really frustrating! #mathsky

This is crazy. It's morally wrong, socially irresponsible, technically stupid, financially dangerous (does that tiny disclaimer saying "don't trust this!" in a tiny font going to hold up in court?). What is up at Google, have they truly given the reins of the company to an unfathomable idiot?

I genuinely cannot believe Google is now showing Gemini-generated medical snippets including *drug summaries and medical advice* to treatserious health conditions.

I checked. It does. With barely a tiny disclaimer about GenAI. How can a (formerly?) trusted company be so incredibly reckless?

Hard disagree. It looks better than any other system out there, by orders of magnitude. Making math easily readable takes work, just like explaining math clearly takes work. Plus it's easy to make a macro--please just don't inflict MSWord upon us.

how i'd learn machine learning in 2025 if i had to start from scratch:

1. find a log that i initially planned to turn into a table leg
2. make it into a puppet that can walk and talk
3. have the puppet, through a series of adventures, turn into a real boy and realize the true value of friendship
