@… American states, probably not, but countries in South America? I’d hesitate that the answer is yes.
When I took geography in middle school (Denmark), I had to be able to point to every country on earth, and name its capital. I doubt the average American could muster the same, though I’m ready to be pleasantly surprised.

A great example of how it's sometimes necessary to break the rules to have your voice heard.
It was amazing to be able to swim in Copenhagen's harbour when I lived there. Every British city with the right geography should be looking to clean up their water and give their citizens access to it like this.

Trail Trap: a variant of Partizan Edge Geography
We introduce a two-player game played on undirected graphs called Trail Trap, which is a variant of a game known as Partizan Edge Geography. One player starts by choosing any edge and moving a token from one endpoint to the other; the other player then chooses a different edge and does the same. Alternating turns, each player moves their token along an unused edge from its current vertex to an adjacent vertex, until one player cannot move and loses. We present an algorithm to determine which pl…

Unraveling the Geography of Infection Spread: Harnessing Super-Agents for Predictive Modeling
Our study presents an intermediate-level modeling approach that bridges the gap between complex Agent-Based Models (ABMs) and traditional compartmental models for infectious diseases. We introduce "super-agents" to simulate infection spread in cities, reducing computational complexity while retaining individual-level interactions. This approach leverages real-world mobility data and strategic geospatial tessellations for efficiency. Voronoi Diagram tessellations, based on specific street networ…

On the geography of $3$-folds via asymptotic behavior of invariants
Roughly speaking, the problem of geography asks for the existence of varieties of general type after we fix some invariants. In dimension $1$, where we fix the genus, the geography question is trivial, but already in dimension $2$, it becomes a hard problem in general. In higher dimensions, this problem is essentially wide open. In this paper, we focus on geography in dimension $3$. We generalize the techniques which compare the geography of surfaces with the geography of arrangements of curves…

I am pleased to report that the London geography in Argylle is completely sane and not at all gibberish.

ONLY KIDDING.

It is the same as every other film - complete garbage. Bad guys are driving down High Holborn, then Union Street, without crossing the river (and their target point was on the north bank when they were actually after people on the south bank.)

There’s a middle path here and no one is going to see it.

Comparative Study of Sand Drawings in Oceania and Africa
People typically consider only European mathematics as orthodox, often intentionally or unintentionally overlooking the existence of mathematics from non-European societies. Inspired by Maria Ascher's two well-known papers on sand drawings in Oceania and Africa, this paper focuses on the strong link between modern mathematics and the mathematics behind the sand drawings. Beginning with a comparison of the geography, history, and the cultural context of sand drawings in Oceania and Africa, we wi…

On the Gonality type invariants and the slope of a fibered $3$-fold

On the Gonality type invariants and the slope of a fibered $3$-fold
The \textit{slope} of a fibered $3$-folds $f:X \to B$ is a relative numerical invariant defined by $λ(f) := K_{f}^{3}/\mathrm{deg}(f_{\ast}ω_{f})$, where $K_{f}$ is the relative canonical divisor and $ω_{f}$ is the relative dualizing sheaf. Establishing slope inequalities is a fundamental problem in the geography of fibered spaces. In this paper, we introduce a new invariant called the \textit{minimal covering degree} as a gonality-type invariant and study a lower bound of the slope increasi…

Evaluation of Geographical Distortions in Language Models: A Crucial Step Towards Equitable Representations
Language models now constitute essential tools for improving efficiency for many professional tasks such as writing, coding, or learning. For this reason, it is imperative to identify inherent biases. In the field of Natural Language Processing, five sources of bias are well-identified: data, annotation, representation, models, and research design. This study focuses on biases related to geographical knowledge. We explore the connection between geography and language models by highlighting thei…

Researchers map 33 new big game migrations across American West
A new set of maps that document the movements of ungulates was published today in the fourth volume of the Ungulate Migrations of the Western United States. The maps in this collaborative U.S. Geological Survey report series reveal the migration routes and critical ranges used by ungulates, or hooved mammals, in the western U.S., furthering scientists' understanding of the geography of big game migrations.

Quantifying the hierarchical scales of scientists'mobility
Human behaviors, including scientific activities, are shaped by the hierarchical divisions of geography. As a result, researchers' mobility patterns vary across regions, influencing several aspects of the scientific community. These aspects encompass career trajectories, knowledge transfer, international collaborations, talent circulation, innovation diffusion, resource distribution, and policy development. However, our understanding of the relationship between the hierarchical regional scale a…

How Language, Culture, and Geography shape Online Dialogue: Insights from Koo
Koo is a microblogging platform based in India launched in 2020 with the explicit aim of catering to non-Western communities in their vernacular languages. With a near-complete dataset totalling over 71M posts and 399M user interactions, we show how Koo has attracted users from several countries including India, Nigeria and Brazil, but with variable levels of sustained user engagement. We highlight how Koo's interaction network has been shaped by multiple country-specific migrations and display…

Oracle Bone Script (OBS), one of the earliest known forms of ancient Chinese writing, holds invaluable insights into the humanities and geography of the Shang Dynasty, dating back 3,000 years. The immense historical and cultural significance of these writings cannot be overstated. However, the passage of time has obscured much of their meaning, presenting a significant challenge in deciphering these ancient texts. With the advent of Artificial Intelligence (AI), employing AI to assist in interp…

Moiré fractals in twisted graphene layers
Twisted bilayer graphene (TBLG) subject to a sequence of commensurate external periodic potentials reveals the formation of moiré fractals (MF) that share striking similarities with the central place theory (CPT) of economic geography, thus uncovering a remarkable connection between twistronics and the geometry of economic zones. MFs arise from the self-similarity of the emergent hierarchy of Brillouin zones (BZ), forming a nested subband structure within the bandwidth of the original moiré b…

Selecting urban regions for metro network expansion to meet maximal transportation demands is crucial for urban development, while computationally challenging to solve. The expansion process relies not only on complicated features like urban demographics and origin-destination (OD) flow but is also constrained by the existing metro network and urban geography.
