I think it's really underappreciated that solar panels are now about as cheap per unit area as mass-produced building materials like wood, siding, shingles/shakes, etc.
The Republican reconciliation bill aims to make solar expensive again in the US through tariffs and taxes.

Nonstandard methods for ultrafilter relation extensions
We study two types of ultrafilter relation extensions with nonstandard methods and provide characterisations of these extensions in terms of generators of ultrafilters. These characterisations are then used to determine whether various relation properties are preserved by these extensions. Lastly, we study the notion of self-divisible ultrafilter and, with the mentioned characterizations, generalize this notion for a class of relations.

vermisst jemand von euch ein Auto mit Berliner Kennzeichen? Da sind sogar noch ein paar Menschen drin
"Auto verirrst sich...ermittlungen dauern noch an....Das Auto habe man im Bereich Brüderstraße angetroffen. „Von wo genau es herkam, ist nicht ganz klar“, teilt Polizeisprecher Jens Artschwager...Wie es doch dazu kommen konnte, ist zurzeit noch unklar. Eine Theorie lautet, dass das Auto aus einer privaten Einfahrt innerhalb des Festivalgeländes kam...."

On the geometry of synthetic null hypersurfaces
This paper develops a synthetic framework for the geometric and analytic study of null (lightlike) hypersurfaces in non-smooth spacetimes. Drawing from optimal transport and recent advances in Lorentzian geometry and causality theory, we define a synthetic null hypersurface as a triple $(H, G, \mathfrak{m})$: $H$ is a closed achronal set in a topological causal space, $G$ is a gauge function encoding affine parametrizations along null generators, and $\mathfrak{m}$ is a Radon measure serving as…

I gotta say I find a lot of AI discourse around higher ed very confusing:
"if ChatGPT can write your essays is college even worth it?"
Did people think math teachers were assigning problem sets because *they* couldn't figure out the answers?

There’s something deeply wrong with a society that watches people get snatched by masked men in unmarked cars & looks the other way.
