KI-generierte Zusammenfassung von Google führt zu Gerüchten:
Vor knapp einer Woche war unser Leitungswasser wegen einer mikrobiologischen Verschmutzung nicht trinkbar. Die Bevölkerung wurde dazu aufgerufen, das Wasser abzukochen.
Nun gehen in lokalen Chats Screenshots rum, die behaupten, es wären PFAS gewesen. Die Google KI-Zusammenfassung spinnt das wohl aus einem Zeitungsartikel zusammen, in dem nebenbei über vergangene PFAS-Verunreinigungen berichtet wurde

Oh, why aren't you a cat person? I'll tell you: my brother was attacked, bitten and scratched on both hands this week by a feral cat in his kitchen and had to go for surgery to get the infected parts out. And he did all this to protect his own cat. I'll be watching those 'cute' cat videos with a different kind of feeling. I've heard they taste similar to rabbits.

A Gentle Introduction to Algebraic Operads
This text, based on the author's Bachelor's thesis, introduces the theory of Algebraic Operads, a mathematical formalism that provides a unifying framework for modern algebra. We demonstrate how the fundamental theories of associative, commutative, and Lie algebras can be fully recovered as categories of representations of three archetypal operads: $\mathsf{As}$, $\mathsf{Com}$ and $\mathsf{Lie}$ -- the so-called 'three graces' of algebra. Following a deductive and self-contained approach, th…

Friedman's $ \mathsf{WD} $ is not parameter-free sequential
Harvey Friedman's $ \mathsf{WD} $ is a weak set theory given by the following non-logical axioms: $ \mathsf{(W)} \; \forall x y \, \exists z \, \forall u \left[ \, u \in z \leftrightarrow ( \, u \in x \; \vee \; u = y \, ) \, \right] $; $ \mathsf{(D)} \; \forall x y \, \exists z \, \forall u \, \left[ \, u \in z \leftrightarrow ( \, u \in x \; \wedge \; u \neq y \, ) \, \right] $. We answer a question raised by Albert Visser which asks whether $ \mathsf{WD} $ is parameter-free sequential. Let $…

Fractional Trudinger-Moser type inequalities with logarithmic convolution potentials
We establish the following fractional Trudinger-Moser type inequality with logarithmic convolution potential $$ \sup_{u\in W^{\frac{1}{2},2}_0(I),\|u\|_{W_0^{\frac{1}{2},2}}\leq1}\int_{I} \int_{I} \log \frac{1}{|x-y|} G(u(x))G(u(y)) \, dx \, dy<+\infty,$$ where $G(s)\leq C\frac{e^{πs^{2}}}{(1 + |s|)^γ}~ \forall s\in\mathbb{R}$ with some constant $C>0,γ\geq1$, the domain $I\subset\mathbb{R}$ is a bounded interval. This type of inequality in the entire space $\mat…

Been experimenting with Shortwave, a frontend to Gmail with serious AI capabilities. So far it impresses me and is able to do the things that Gmail Gemini was failing me at. Main drawback is it's fairly expensive for a consumer product.

Last year I spent some time in the part of Texas where the floods hit on the Guadalupe River last week.
Even to my California-kid eyes, eyes that rarely see a real river, the Guadalupe, as it passed through Comfort, Texas, was more of a creek than a river.
Over the last day I've wondered "what if I had been there when the flood hit?" I am used to having fairly serious topology, so I would have had trouble there in Texas figuring out which way to go to find "hi…

HBAR entropy in causal diamond geometry: A near-horizon perspective
In this article we extend the Horizon Brightened Acceleration Radiation (HBAR) framework to the causal diamond (CD) spacetime. We study a cloud of two-level atoms, injected at random times in the asymptotic past of the CD, freely falling toward its causal horizon and emitting scalar radiation via a weak dipole coupling to a quantum field. In the near-horizon region, an emergent conformal symmetry-captured by conformal quantum mechanics (CQM)-governs the field dynamics and allows analytic contro…
