Earlier today i sent a derivation to the statmech group chat where I call the gamma function "my babygirl" bc I was being silly last night and forgot to clean it up 😭
At least once a week I am deeply thankful for the gamma function

If I want to teach undergraduate students about driven non-equilibrium systems, which two toy models should I choose? The mathematics must be intuitive, and the simulations must be easy. What do you suggest? #statmech #physics #complexsystem #systemsbiology

i would be surprised if anyone built general-purpose optimization intuition on this one specifically, maybe once you generalize it to statmech for a lot of balls on a lot of hills

Every new statmech thing I learn feels like remembering something I already knew. Every e&m thing I know should have already learned feels like learning something entirely new

Fwiw if the argument against consciousness being statmech is just "which statmech would that be" is just, well I think your response is good and I think the rebuttals I've heard are category errors.

"but diffusion comes out of statmech!", Alex is going to say, and i am going to tell him that it is his turn to study statistical mechanics, which somehow will not get you banned on bluesky

this didn't occur to me until like today because I don't think it's a thing that ever occurs to anyone as a thing to try to do except for people who like doing statmech

and let's be real, statmech is famous for driving people to suicide. god doesn't want us to know.

this is, in theory, possible, but would require being on a level of statmech that would instantly obliterate your face (like in Raiders of the Lost Ark)

Statmech is the glue that holds, well, honestly most of modern physics together.

agree
statmech is interesting to me because it's developed good intuitions about certain kinds of collections of agents interacting, much like game theory has developed good intuitions about different kinds of agents interacting. it's cool to see different formalisms and bridges between them

But now I'm really tempted to set up a GitHub repo for the statmech class I'm taking next term, since overleaf only lets you share with one potential editor and I want to share my TeX files with several classmates and it's nice keeping all my related scripts in one place... But I feel silly doing it

Fluctuation-dominated phase ordering in the one-dimensional truncated inverse-distance square Ising model

It was one of my firm Bs in undergrad that confirmed I was right to be looking at a major hop for my master's degree, lol.
Weirdly my best grades were in Classical Mechanics and StatMech, where I was top of the class in my year. But quantum, classical electromagnetism, and mathematical methods? Bs.

Thermo/statmech side note: I had a terrible textbook with one wonderful sidebar: "the thermodynamic definition of 'never'." [I think it was a monkeys writing Shakespeare calculation, assuming a monkey that is equally likely to strike any key.]

You don't need to know much about statmech for this, although it helps if you want to read papers on this subject: arxiv.org/pdf/1505.02780 or arxiv.org/pdf/1702.00850

I somehow ended up on a starter pack "people in quantum"
Let me clarify that my work is more of a statmech/condensed matter theory. I don't work in tech, and my knowledge of it is mostly "peripheral"

Basically, insofar as we identify the 2nd with the -1st Law in the setting of StatMech, we cannot prove it. (This position of mine is far from uncontroversial.) Therefore, don't identify them.

From the PoV of StatMech, I see why some might find this distinction punctilious. I think it is worth separating them, because:
Relaxation is supposed to occur spontaneously, w/o intervention, universally. Explaining this is extremely challenging, and I am not certain the human race has succeeded.

the idea of the "first thing" is that, since Boltmann's entropy is just phase volume, which is dynamically preserved, and because the max entropy cell is overwhelmingly the hugest, the fraction F that could move into a given smaller cell F' is just little in comparison and is ignored. okay but

Onto StatMech. Here, we find entropies distinct from Clausius', but which hopefully underwrite his in some sense, but also in any case _extend_ the concept to non-eq states. As a result, it may now be possible to view relaxation as a species of entropy increase, and reduce our postulates by one.

i have looked at Caratheodory's formulation! and a few other axiomatic approaches. it was extremely interesting.
at this point i moreso have conceptual issues rather than mathematical ones, and not so much with Thermo itself but its relationship to StatMech. I've been saying a lot about this today.

A is an assumption in common between statmech and thermodynamics, the generic relaxation to equilibrium. i don't know how to justify it. it happens, though.
B could be taken as circumscribing the applicability of classical thermodynamics.
C is literally false, by Poincare recurrence.
