Following a discussion on reddit of all places, here's a poll. Please spread far and wide because [garbled audio, static, unintelligible noises]
The question is: do you normally listen to and enjoy audiobooks?
Also, this is what I mean by "inner monologue" (sorry it's not WP but that page terrifies me)

How Inner Monologues Work, and Who Has Them
Inner monologues can represent a rich experience for some, as long as they don’t get out of hand.

Surfaces and interfaces of infinite-layer nickelates studied by dynamical mean-field theory
Infinite-layer nickelate superconductors are typically synthesized as thin films and thus include, besides the more bulk-like inner layers, distinct surface and interface layers in contact with the vacuum and substrate, respectively. Here, we employ density-functional theory and dynamical mean-field theory to investigate how electronic correlations influence these surface and interface regions. Our results show that electronic correlations can significantly modify the electronic structure, even…

Enhanced Pebble Drift Across Planet-Opened Gaps in Windy Protoplanetary Disks
When a giant planet forms in a protoplanetary disks, it carves a gap around its orbit separating the disk into two parts: inner disk and outer disk. Traditional disk accretion models, which assume material transport is driven by viscosity, reveal that the planet-induced gap acts like a filter which blocks large dust grains from flowing into the inner disk. However, there is growing evidence that material transport may be driven by magnetically-driven winds instead. By carrying out a suite of tw…

Am Anfang dachte ich ja "Ein paar Fans für den Sticker wird's geben, denen schenk ich welche gegen Porto."
Dann wurden's immer mehr.
Seit vorgestern hab ich einen Etsy-Shop, und nun schon 60 Sticker verkauft.

Key takeaway is at end of this article [gift link].
Sales of new exurban houses are falling, but there's unmet demand for urban infill. If cities & inner suburbs repeal offstreet parking mandates & cut minimum lot sizes, builders will keep building.

As Housing Demand Continues to Fall, Builders Get Creative
A slow start to the home building market this year has prompted some builders to increase incentives and build on smaller lots.

Der Zug von Hamburg nach Kiel, beziehungsweise nach Flensburg, wird immer in Neumünster geteilt. Für Menschen, die diese Verbindung das erste Mal nutzen, ist es wie ein Persönlichkeitstest. Die anderen Fahrgäst:innen können sehr klar erkennen, was für einen Typ Mensch vor einem steht. Und heute habe ich festgestellt, nicht zum ersten Mal, dass sich manche Menschen besser nicht reproduzieren sollten.

Some new results on $Δ$-spaces
A topological space $X$ is a $Δ$-space (or $X \in Δ$) if for any decreasing sequence $\{A_n : n < ω\}$ of subsets of $X$ with empty intersection there is a (decreasing) sequence $\{U_n : n < ω\}$ of open sets with empty intersection such that $A_n \subset U_n$ for all $n < ω$. In this note we prove the following results concerning $Δ$-spaces. 1) Every $T_3$ countably compact $Δ$-space is compact. 2) If there is a $T_1$ crowded Baire $Δ$-space then there is an inner model with a meas…

Best approximation from the positive cone of an inner product lattice
Let $E$ be a directed (i.e., positively generated) ordered vector space endowed with an inner product. In this note, we prove that the following statements are equivalent: i) $E$ is a vector lattice and its norm induced by its inner product is a lattice norm. ii) The metric projection onto the positive cone $E^+$ of $E$ exists and it is both isotone and subadditive. Moreover, in this case, the best approximation to any $x \in E$ from $E^+$ coincides with its positive part $x^+$. This result ext…

A Solovay-like model at $\aleph_ω$
Assuming the consistency of ZFC with appropriate large cardinal axioms we produce a model of ZFC where $\aleph_ω$ is a strong limit cardinal and the inner model $L(\mathcal{P}(\aleph_ω))$ satisfies the following properties: (1) Every set $A\subseteq (\aleph_ω)^ω$ has the $\aleph_ω$-PSP. (2) There is no scale at $\aleph_ω$. (3) The Singular Cardinal Hypothesis (SCH) fails at $\aleph_ω$. (4) Shelah's Approachability property (AP) fails at $\aleph_ω$. (5) The Tree Property (TP) holds at $\…
