A new solution of Einstein-Maxwell field equations in isotropic coordinates
In this work, we provide a novel exact solution to the Einstein-Maxwell field equations in isotropic coordinates for charged anisotropic matter distribution, achieved by considering one of the metric potentials as well as a particular form of pressure anisotropy and electric field. We analysed all physical features of a realistic star to ensure the model's viability, and we observed that it met all the physical plausibility conditions. The gravitational potentials and matter variables are well-…

Page Curve for an Evaporating Schwarzschild Black Hole in Dimensionally-Reduced Model of Dilaton Gravity
We study entanglement entropy of quantum fields in a (1+1)-dimensional model of dilaton gravity derived from the four-dimensional Einstein-Hilbert action by dimensional reduction. Scalar matter is coupled to gravity, while the back-reaction is included via the Polyakov-Liouville action. This theory exhibits both eternal and evaporating Schwarzschild black hole solutions. The fine-grained entropy in a collapse scenario is investigated by applying the "island rule" via the quantum extremal surfac…

Anisotropic compact star model with quadratic equation of state in paraboloidal spacetime
In this work, we report a new exact solution of Einstein's field equations for static spherically symmetric anisotropic matter distributions on the background of paraboloidal spacetime by assuming a quadratic equation of state. The model parameters were found by matching the interior spacetime metric with the Schwarzschild exterior metric. The new exact solution is non-singular and meets all of the physical plausibility conditions for a realistic compact star. The detailed physical analysis of …

Really enjoyed @…’s thoughtful and entertaining talk at #smashingconf today! Amazing to see how philosophical ideas influenced the design of iA’s apps and what designers can and could learn from philosophy – and vice versa. A lot of food for thought!…

A Timeless Game: A Game-Theoretic Model of Mass-Geometry Relations
We develop a minimal, timeless game-theoretic representation of the mass-geometry relation. An "Object" (mass) and "Space" (geometry) choose strategies in a static normal-form game; utilities encode stability as mutual consistency rather than dynamical payoffs. In a 2x2 toy model, the equilibria correspond to "light-flat" and "heavy-curved" configurations; a continuous variant clarifies when only trivial interior equilibria appear versus a continuum along a matching ray. Philosophically, the po…

How Language Models Conflate Logical Validity with Plausibility: A Representational Analysis of Content Effects

How Language Models Conflate Logical Validity with Plausibility: A Representational Analysis of Content Effects
Both humans and large language models (LLMs) exhibit content effects: biases in which the plausibility of the semantic content of a reasoning problem influences judgments regarding its logical validity. While this phenomenon in humans is best explained by the dual-process theory of reasoning, the mechanisms behind content effects in LLMs remain unclear. In this work, we address this issue by investigating how LLMs encode the concepts of validity and plausibility within their internal representa…

Day 18: Mark Oshiro
Having just learned that Oshiro is nonbinary, they're an instant include on this list. In veering extremely heavily towards YA, and losing a spot that would have gone to an absolutely legendary mangaka, anime writer, or feminist philosopher, but "Anger is A Gift" and "Each of us a Desert" are just that good, and I'm trying to steer a bit towards towards lesser-known authors I respect.
I already mentioned "Anger is a Gift" above, but to recap, it's a painful, vivid, and beautifully honest story of queer love, loss, and protest against an oppressive system. CW for racist police murder, intergenerational trauma, and police brutality against highschool students. It's a book a lot of Americans could benefit from reading right now, and while it's fiction, it's not fantasy or sci-fi. Besides the themes and politics, the writing is just really solid, with delicate characterization and tight-plotted developments that are beautifully paced.
To me "Each of us a Desert" is maybe even more beautiful, and Oshiro leaps into a magnificent fantasy world that's richly original in its desolation, dark history, lonely characters, and mythical magic. Particularly the clearly-not-just-superscription but ambiguously-important/powerful magical elements of Oshiro's worldbuilding are a rare contrast to the usual magic-is-real-here's-how-it-works fare, and pulling that off a all as they do is a testament to their craft. The prose is wonderful, probably especially so if you speak Spanish, but I enjoyed it immensely despite only knowing a few words here and there. The rich interiority of the characters, their conflicts both with each other and within themselves, and the juxtaposition of all that against origins in cult-like ignorance allows for the delivery of a lot of wisdom and complex truths.
Between these two books, so different and yet each so powerful, Oshiro has demonstrated incredible craft and also a wide range of styles, so I'm definitely excited to read more of their work and to recommend them to others.
I'm also glad to have finally put a nonbinary author on this list; the others I had in mind won't make it at this point because there's too much genre overlap, although I'll include them in my didn't-make-it list at the end. I've now got just 2 slots left and have counted up 14 more authors that absolutely need to be mentioned, so we'll see what happens.

Five points for the Polyakov Bootstrap

Five points for the Polyakov Bootstrap
Higher-point correlation functions encode the data of infinitely many 4-point correlators in conformal field theory (CFT). In this paper, we develop new tools to efficiently extract this data from multi-point crossing equations. Concretely, we generalize the functionals constituting the so-called Polyakov bootstrap of 4-point correlators to the case of 5-point functions in one-dimensional CFTs. We first construct the crossing symmetric Polyakov blocks, and then derive sum-rules by requiring con…

Day 5: Robin Wall Kimmerer
I'm taking these liberty of changing my hashtag and expanding the intent of this list to include all non-men, although Kimerer is a woman so I'll get to more gender diversity later... I've also started planning this out more and realized that I may continue a bit beyond 20...
In any case, Robin Wall Kimmerer is an Indigenous academic biologist and excellent non-fiction author whose work touches on Potawotomi philosophy, colonialism (including in academic spaces), and ideas for a better future. Anyone interested in ecology, conservation, or decolonization in North America will probably be impressed by her work and the rich connections she weaves between academic ecology and Indigenous knowledge offer a critical opportunity to expand your understanding of the world if like me you were raised deeply enmeshed in "Western" scientific tradition. I suppose a little background in skepticism helped prepare me to respect her writing, but I don't think that's essential.
I've only read "Braiding Sweetgrass," but "Gathering Moss" and her more recent "The Serviceberry" are high on my to-read list, despite my predilection for fiction. Kimmerer incorporates a backbone of fascinating anecdotes into "Braiding Sweetgrass" that makes it surprisingly easy reading for a work that's philosophical at its core. She also pulls off an impressive braided organization to the whole thing, weaving together disparate knowledges in a way that lets you see both their contradictions and their connections.
The one criticism I've seen of her work is that it's not sufficiently connected to other Indigenous philosophers & writers, and that it's perhaps too comfortable of a read for colonizers, and that seems valid to me, even though (perhaps because I am a colonizer) I still find her book important.
An excellent author in any case, and one doing concrete ideological work towards a better world.
