One Thousand and One Conjectures

Joins measurement theory — the idea that the error bar is itself a signal — to third-century political history. A papyrus can be dated only as precisely as its own dating apparatus allows: regnal formulas, titulature, and bureaucratic boilerplate are what let…

Greenland's ice sheet and Roman monetary history are usually studied by different disciplines, yet the first quietly records the second: lead deposition in Greenland ice cores derives largely from the atmospheric fallout of Roman smelting, and because silver was refined from lead-rich…

The Wadi al-Jarf papyri preserve the logbook of Merer, a boat-crew overseer under Khufu, recording day by day his gang's deliveries of Tura limestone to the Giza works — effectively a shipping ledger for the Great Pyramid. Independent arrivals at a facility,…

Joins autocatalytic reaction kinetics to the sociolinguistics of conquest: in Egypt's dated documentary papyri, the replacement of Greek and Coptic by Arabic behaved like a chemical substitution running with a nearly universal rate constant. The mechanism is autocatalytic — every office and…

Joins atmospheric physics to colonial sociolinguistics: just as pressure thins exponentially with altitude at a fixed scale height, Greek thinned with river distance up the Nile from Alexandria at a fixed exponential scale length. The mechanism is demand decay: Greek was the…

Joins the economics of crime — Gary Becker's principle that offenses rise when their returns rise and legitimate wages fall — to the Deir el-Medina archives of the royal tomb-builders. The workmen were paid in grain, and the ostraca record their ration…

Milton Friedman's plucking model of business cycles holds that an economy runs along a capacity ceiling from which recessions pluck output downward: deep slumps rebound fast, while booms say nothing about the next bust. This conjecture transposes that asymmetry onto documentary papyrology's…

In financial crises, liquidity flees risky assets and concentrates into a handful of safe ones — the flight to quality. This conjecture maps that dynamic onto papyrological geography: when aggregate documentary output contracts, surviving documentation should concentrate into fewer, safer places, because…

Taylor's law — fluctuation scaling from statistical physics and ecology — says that across populations, variance grows as a power of the mean: exponent 1 for independent Poisson noise, 2 for perfectly synchronized fluctuation. This conjecture applies it to the geography of…

Absenteeism econometrics has two robust modern findings: absence hazard spikes on workdays adjacent to rest days, as workers manufacture long weekends, and total absence is dominated by a small cadre of chronic absentees. This conjecture claims the pharaoh's own tomb-builders behaved identically…

Joins the diffusion of literary-epistolary fashion to settlement hierarchy in Greco-Roman and late antique Egypt: the private letter is the one literary micro-genre with tens of thousands of dated, placed witnesses, and its opening and closing formulas (the chairein prescript, the erroso…

Coptic literacy was built by theology before administration touched it. The script community was created by scripture-reading and monastic institutions, and only once that community existed did Coptic seep into contracts, letters, and receipts — so documentary Coptic should lag literary and…

This connects selective diacritical pointing in early Arabic documents with the sociology of correspondence. Pointing cost time and scribes applied it selectively; the question is what governed the selection. The conjecture: pointing density tracks social distance between writer and recipient. Between intimates,…
