Mathematics is a powerful language, but getting acquainted to it can be painful and discouraging, especially if you are not really interested in it. But it can be different!

If you use GMail, AI (Gemini) was turned on yesterday by default and now scans all of your content for machine learning. To turn off, go to Settings>General and scroll down. Uncheck the box for "Smart features."

There's other "Smart" add-ons as well, but that's the one that reads your content.

Theorem. There exist irrational numbers x and y such that x^y is rational.

Getting nervous for the talk I'm about to give at a workshop about "using AI to drive impact" which features slides such as these.
Slide is titled: You don't need to use LLMs. Science is a process of collaborative meaning making, by which we try to understand the world Even if AI were perfect, we rely on it at our peril — it is not science if we (i.e., humanity as a whole) do not understand and cannot recapitulate all parts of it I very, very rarely use LLMs myself. You can give yourself permission not to. Don’t FOMO yourself into it Conclusion: Don't rely on something you don't understand and can't control If you must use LLMS: 1. Treat them like you would an intern: only use them for things you can easily and thoroughly check 2. Make your process as robust as possible 3. Be aware of your own (human) cognitive biases

I like this idea!

I have my students co-develop class policies, and they pretty much unanimously chose to ban AI in the class. There were a few questions about using Grammarly, but those were the only real exceptions any students expressed (and even then, we talked about alternatives to that and they were open to it)

[5/6] I don't know whether these changes will be good or bad in the long run. If you're sad, I can't talk you out of it.

But it's still true: if higher ed wants to play a meaningful role in 21c knowledge production, we have to seize the means of production and make them public.

The result of an extremely fun and unusual collaboration are finally starting to appear. When this started, purely coincidentally, three years ago, we had only a keyword in common: GENERIC (all caps). And of course completely orthogonal backgrounds.

We propose a coordinate-invariant geometric formulation of the GENERIC stochastic differential equation, unifying reversible Hamiltonian and irreversible dissipative dynamics within a differential-geo...

Yet again, we can't afford to let LLMs become a source of epistemic grounding for society.

[Scene is a high school classroom. A teacher is writing on the whiteboard 'ACT 2 SCENE 3'.] TEACHER: OK class - open up Macbeth to Act 2 Scene 3... TEACHER: So - does anybody have any ideas on Shakespeares meaning behind the character of 'the Porter' in this scene? [A voice comes from off-scene, behind the teacher's back[. VOICE: ABSOLUTELY NOTHING. TEACHER [turning round]: Sorry….. who are you? [We see a wider scene that shows it is the GHOST OF WILLIAM SHAKESPEARE, hovering over the heads of the startled students] SHAKESPEARE: I'm the Ghost of Shakespeare and I've come back to say: this scene means *absolutely nothing*. The Porter is a funny drunk bloke I lobbed in to cover a costume change! I mean like, not everything I did was genius OK? Stop giving me the ick. TEACHER: So um...what do you suggest we study? SHAKESPEARE: The most important text in British culture! TEACHER: Which is...? SHAKESPEARE: 'Bollocks People Say on the Internet.' TEACHER: You think we should study... bollocks people say on the internet? SHAKESPEARE: Yes. TEACHER: But Mr Shakespeare... your Porter scene was a question in a past GCSE paper... We need to analyse it so the kids don't end up failing their exams... SHAKESPEARE: Yes, and I'm just suggesting you should analyse Bollocks People Say on the Internet instead, so they don't end up painting flags on roundabouts. [Silent pause] TEACHER: OK class - open up your phones to X... [ends]

Another milestone for our "oscillation book" tonight, with a new heavily edited version, introducing linear algebra much earlier and integrating some notions of harmonic analysis in the text. Still aiming at a "non-expert" audience.

2-panel SMBC comic update. The first panel has a narration box saying "Caveman" where two cavemen are looking out at the ocean. One says "us not know what on other side of ocean." The second panel has a narration box saying "Caveman Physicist" where the same caveman now says "Past ocean... Science breaks down. Is Ocean singularity" as the other caveman marvels.
