Transcendental formulas for the coefficients of Ramanujan's mock theta functions
Ramanujan's 1920 last letter to Hardy contains seventeen examples of mock theta functions which he organized into three "orders." The most famous of these is the third-order function $f(q)$ which has received the most attention of any individual mock theta function in the intervening century. In 1964, Andrews--improving on a result of Dragonette--gave an asymptotic formula for the coefficients of $f(q)$ and conjectured an exact formula for the coefficients: a conditionally convergent series tha…

Origins of the Ising model

Origins of the Ising model
In 1925, Ernest Ising published a paper analyzing a model proposed in 1920 by Wilhelm Lenz for ferromagnetism. The model is composed of constituent units that take only two states and interact only when they are neighbors. Ising showed that in a linear chain the model does not present an ordered ferromagnetic state, a frustrating but correct result. However, Rudolf Peierls demonstrated in 1936 that the model does in fact present an ordered state in two dimensions, and therefore in three dimensi…

Teacher Effects on Student Achievement and Height: A Cautionary Tale
Founded in 1920, the NBER is a private, non-profit, non-partisan organization dedicated to conducting economic research and to disseminating research findings among academics, public policy makers, and business professionals.

I've had a few of these thoughts stuck in my craw all day because I watched this liberal historian talk about the Galleanisti.
https://youtube.com/shorts/93yHEn8BYE4
Basically, she says that "of course the government had the right to target them." Then she goes on to talk about how it became an excuse to carry out a bunch of attacks on other marginalized people. Now, the Galleanisti had been bombing the houses of politicians and such. I get where she's coming from saying that one of their targets "was in the right" to try to catch them. But there's some context she's not talking about at all.
These were Italian anarchists, so they were not white and they were part of an already marginalized political group. Basically all of Europe and the US was trying to wipe out anarchists at the time. Meanwhile, the sitting president at the time showed the first movie in the White House. That movie was KKK propaganda, in which he was favorably quoted. The US was pretty solidly white supremacist in the 1920's.
Like... A major hidden whole premise of the game "Bioshock: Infinite" is that if you went back to the US in the 1920's, and you had magic powers, you would absolutely use them to kill as many cops as possible and try to destroy society. There's a lot of other stuff in there, I don't want to get distracted, but "fuck those racists," specifically referring to the US in the 1920's, was a major part of a major game.
Those Italian anarchists were also stone cutters. They carved grave stones. But the dust from that can kill you, much like black lung for coal miners. So they were dying from unsafe working conditions, regularly raising money to support dying coworkers and then carving gravestones for those same coworkers.
Now, I personally think insurrectionary anarchism is a dead end. I disagree with it as a strategy. We've seen it fail, and it failed there. But of course it makes sense that they wanted to blow up the government.
...And that's the correct way to structure that. When you say, "of course they were in the right" you're making a very clear political statement. You could easily say, "the cops in Vichy France had every right to hunt down the French Resistance." You would technically be correct, I guess. But it would really say something about your politics if you justified the actions of Nazi collaborators over those fighting against the Nazis.
And you may say, "oh, but the Nazis didn't have justification for anything. They invaded a sovereign nation, so their government wasn't legitimate anyway."
To which I would reply, "have you considered a history book about the US?"

Before any #ExpandingHorizons project would go ahead, the #ELT has to be finished, of course - here is the current timeline as shown by Barcons at #ag2025goerlitz today.

The #ExpandingHorizons timeline - FIRST the science case has to be defined with the landscape of the 2040s in mind, THEN technology becomes important. And the DG emphasizes that #ESO has no favorite. #ag2025goerlitz

Tomorrow all morning of #ag2025goerlitz will be devoted to #ExpandingHorizons - #ESO DG is introducing this vision beyond the ELT.

At #ag2025goerlitz now what's probably the last public discussion of the #Denkschrift for German astronomy - the text of which is mostly written already but prioritizing and adaptation to current developments has yet to occur.

Strong words at #ag2025goerlitz as the war against science by the current White House is also affecting German astronomy big time: in space as shown here as well as on the ground with dramatic cuts to the NSF.

Relaminarization of turbulent puffs in pipe flow
This study examines the relaminarization of turbulent puffs in pipe flow using highly resolved direct numerical simulations at Reynolds numbers of 1880, 1900, and 1920. The exponential decay of the total energy of streamwise velocity fluctuations and the weak dependence of the decay rate on the Reynolds number were verified. In the cross-section of the laminar-turbulent interface at the trailing edge of the puff, an analysis of the spatio-temporal evolution of the streamline patterns reveals a …

$q$-Binomial expansions of the truncated MacMahon's $q$-series

https://arxiv.org/abs/2509.06357 https://arxiv.org/pdf/2509.06357

$q$-Binomial expansions of the truncated MacMahon's $q$-series
In 1920, MacMahon introduced two families of $q$-series to study divisor sums. Recent work has shown that MacMahon's $q$-series are closely connected to overpartitions and $3$-colored partitions. Merca introduced truncated forms of MacMahon's $q$-series to generalize earlier results by Andrews-Rose and Ono-Singh, and posed two conjectures regarding the $q$-binomial expansions of these truncated series. In this paper, we provide combinatorial proofs of Merca's conjectures through the combinatori…

Sketches of Nonuniformly Elliptic Schauder Theory
Schauder theory is a basic tool in the study of elliptic and parabolic PDEs, asserting that solutions inherit the regularity of the coefficients. It plays a central role in establishing higher regularity for solutions to a broad class of elliptic problems exhibiting ellipticity, including those involving free boundaries. In the linear setting, Schauder theory dates back to the 1920-30s and is now considered classical. Nonlinear extensions were developed in the 1980s. All these classical results…

Welcome back to #ag2025goerlitz - here's the agenda for the morning(s): https://ag2025.astronomische-gesellschaft.de/program/plenary.php

Good Morning #Canada
#HappyBirthday to me. It's my 69th, and mentally, I feel young, but parts of my body have exceeded the "best before date." According to bornglorious .com there are 137 "famous" Canadians born on August 24th. Most are nobodies like me - politicians, actors, or NHL players you've never heard of. But there are a few notables. Like Alex Colville (1920-2013), a favourite Canadian conceptual painter. Or chain-smoker René Lévesque (1922-1987), who tried to tear Canada apart. But perhaps the Canadian born on this day with the most impact is Rocky Johnson (1944-2020). Born in Amherst, Nova Scotia, Johnson was a Canadian pro wrestler and the first black champion in WWE history. Oh yeah.... he was also the father of Dwayne "The Rock" Johnson.
