@DavidKButlerUoA Surface area is still a side issue I guess 😂

[Damien Warman @DamienW]

@pahlkadot Fat to balance the acid, heat to bring the flavour up, tahini/za’atar/chile flakes?

[Damien Warman @DamienW]

@drspacejunk I guess because we got beyond thunderdome instead?

[Damien Warman @DamienW]

@DavidKButlerUoA So in the end we’ll have a dust/fractal, but maybe we can quantify how far away from “flat” we are at each step? I guess I’m claiming that this will flatten out in the limit because we’ve cut out all the bits that could tear…

[Damien Warman @DamienW]

@DavidKButlerUoA And then inside that triangle, we find its incircle, and cut that out. So our figure so far is a “triangle” minus its “incircle”, which is three “triangle” “legs”. And now repeat that for each of the three legs, and so on; I guess this is an Apollonian gasket on the sphere?

[Damien Warman @DamienW]

@DavidKButlerUoA I recently watched a talk where a noted mathematician exposited that there were many things we can prove that he felt we do not understand.

[Damien Warman @DamienW]

@gomichild I sea what you did there

[Damien Warman @DamienW]

@gomichild Iced VoVo, for good or ill

[Damien Warman @DamienW]

@doctorow Typo here, “Chandler” for “Hammett”. (Great thread, I believe Brust is one of America’s greatest fantasists.)

@DavidKButlerUoA @PratchatPodcast @McKenzie_Ben Let me know if you would like to borrow a copy sometime

[Damien Warman @DamienW]

@DavidKButlerUoA Then ∫_I f = ∫_dI F, where ∫_dI F is “evaluate F at the boundary in some suitable way”

[Damien Warman @DamienW]

@DavidKButlerUoA Another thought, perhaps provoked by lunch being a bit late: how do you feel about writing some version of 1-variable FTC like this: F some antiderivative of f (really F is an equivalence class, and f=dF for some suitable “derivative”), I an interval, dI its endpoints/boundary

[Damien Warman @DamienW]

@DavidKButlerUoA Anyway, idle thoughts provoked by noticing things in the different ways engineering, mcc, probability, and maths Ia/b all seem to tackle (multiple) integration subtly differently

[Damien Warman @DamienW]

@DavidKButlerUoA When we have I think THING and it has partial derivatives inside it, I wonder about how to keep some sort of unit or “speed” or velocity in mind. Like thinking of a determinant as a gadget for volumes or areas, normalised for the cross product by inserting unit vectors in the top

[Damien Warman @DamienW]

@DavidKButlerUoA Also I wonder if being able to play with a physical planimeter—a machine that calculates areas via greens theorem—might be interesting

[Damien Warman @DamienW]

@DavidKButlerUoA Can you connect it to your recentish thoughts about integrals in probability?

@rantyben Read this (after learning about bike fitting), thought “to avoid cramped writing hand select nib suitable to your height” 🤔 (then looked at the image, all became clear)
