Sieben Millionen demonstrieren in den USA gegen Trumps autoritäre Politik – und der Präsident beschwichtigt lächelnd: „Das ist ein Witz.“ Die Republikaner wünschen sich Eskalation, bekommen aber eine friedliche Massenbewegung. Trump erreicht, was die Demokraten nicht schafften: Er vereint die Opposition. @…

„No Kings”-Protest: Die Kronenklauer
Hat Donald Trump die Opposition geeint? Die "No Kings"-Proteste scheinen ein erstes Zeichen dafür zu sein.

Parametrized Topological Complexity for a Multi-Robot System with Variable Tasks
We study a generalized motion planning problem involving multiple autonomous robots navigating in a $d$-dimensional Euclidean space in the presence of a set of obstacles whose positions are unknown a priori. Each robot is required to visit sequentially a prescribed set of target states, with the number of targets varying between robots. This heterogeneous setting generalizes the framework considered in the prior works on sequential parametrized topological complexity by Farber and the second au…

Adding another post. This one is a bit less polished, but I want to get it out. As things get harder for everyone, I'm seeing a greater tendency to want to grasp onto revolutionary fiction such as #Andor. I think there's value in that, but it has to come with an informed critique.
> We are so thirsty for hope that we will drink it up, even when that hope comes from a fiction and the truth behind the hope is poison. In Andor, we see the worst elements sacrifice themselves for some of the best. The revolution goes through a process of purification, the complicated elements weeding themselves out to make room for the simplified good, as the rebellion unifies. In reality, this tends to be the opposite how things actually work.

> [The Urban Guerilla movement of the 60's through the 80's] centered militant revolution. In doing so, they omitted or cut themselves off from the logistic support needed to sustain such revolutionary activity. The trauma of carrying out violence further isolated and radicalized them. Lacking infrastructure for trauma healing, their decay escalated and became unrecoverable. Ultimately, their revolutionary movements both emulated and reinforced the status quo they were trying to resist.
> There emerges a strange historical parallel that is difficult to see from within the dominant paradigm. The competitive politics of electoralism derives from heroic competition, where people (typically men) compete (often violently) for control over a territory or people. Thus the insurrectionary enters into the very same competition as a challenger, not against the system of domination but for control over it. The success of the revolution, then, does not abolish the system of violent domination but changes rather replaces its management.
> Many modern anarchists will be quick to point out the disconnect between ends and means. While authoritarian projects often assert that "the ends justify the means," and Andor implies the same, anti-authoritarian projects assert the ends and the means are not only united but are, in fact, the same.
This is still very much something I'm actively editing, but I'd still love feedback to help me refine it to it's final form. Typo catches and clarifying questions welcome.

On the Irreducibility of the Cuboid Polynomial $P_{a,u}(t)$

On the Irreducibility of the Cuboid Polynomial $P_{a,u}(t)$
In this paper we consider the even monic degree-8 cuboid polynomial $P_{a,u}(t)$ with coprime integers $a\neq u>0$. We prove irreducibility over $\mathbb{Z}$ by excluding all degree-8 splittings. First, any putative $4{+}4$ factorization is shown to force a specific Diophantine constraint that has no integer solutions, via a short $2$- and $3$-adic analysis. Second, we exclude every $2{+}6$ factorization using an exact divisor criterion together with a discriminant obstruction. Finally, after r…

The Lurie/Mandelman RV ban is still set to go into effect and tow people's homes on Nov. 1, the same day SNAP expires and at the same time federal agents are in the Bay to terrorize immigrants.

All Eyes on the Mayor’s RV Ban - No Tows Before Housing!
DSA SF is continuing its opposition to Daniel Lurie’s two-hour restriction on RV parking, which will take effect on November 1st, 2025. We know this policy for what it is - the latest attempt by San Francisco’s oligarch Mayor to exile poor and working class people from the City. While San Francisco has put in place a refuge permit program, it’s deeply flawed. The City’s initial eligibility list excludes many longtime RV residents, and those that are eligible have an uncertain offer of …

The bending of a straight line

The bending of a straight line
In gravitational lensing, the usual viewpoint is that light bending measures how a ray deviates from a straight line in Euclidean space. In this work, we take the opposite perspective: we ask how a straight line bends in a curved space, such as optical geometry-that is, how it deviates from geodesics. Using the Gauss-Bonnet theorem, we show that, at leading order, the deflection angle can be written as the integral of the geodesic curvature of a straight line in curved space. This reformulation…
