**A Hyper-Catalan Series Solution to Polynomial Equations, and the Geode**

“_....the hyper-Catalan numbers 𝐶𝐦 count the number of subdivisions of a polygon into a given number of triangles, quadrilaterals, pentagons, etc. (its type 𝐦), and we show that their generating series solves a polynomial equation of a particular geometric form. This solution is straightforwardly extended to solve the general univariate polynomial equation._”

**Threshold fertility for the avoidance of extinction under critical conditions**

“_The results indicate that the fertility rate should exceed 2.7 to avoid extinction. The extinction threshold is reduced by a female-biased sex ratio. We argue that the present results explain the observed phenomena of female-biased births under severe conditions as an effective way to avoid extinction._”

“_ he people who made these artefacts originated in the mainland of northwest Europe, crossed Doggerland into what is now Britain, and eventually reached the far north of the Isle of Skye. Here, they adapted to live in a fragmented, fluctuating, and volatile environment amid melting glaciers, mountains, and oceans—vastly different from the low-lying environments of their homelands on the northwestern edge of the Great European Plain._”

🇬🇧 🇮🇳 **Company-State at Home: The East India Company and the Fiscal System in Eighteenth-Century Britain**

“_This article shows that fiscal capacity was not created only by government bureaucracies: the ‘company-state at home’ model presented here complements the narrative of the ‘fiscal-military state’ by showing that much fiscal revenue from trade was realized through the action of the English East India Company (EIC). Lacking the capacity to enact exhaustive laws, carry out complex calculations, or effectively manage a large bureaucracy, the English state relied on the administrative capacity of the EIC to collect customs on the East Indies trade._”
