Why Calendars Are So Weird, and What Might Be Done About It – Atlas Obscura

Imagine a calendar that is the same every year—sort of.

Calendars are fundamentally weird—after all, none of the many divisions of time we use can be accurately and consistently pegged to the movements of the Earth, Moon, planets, and stars. A day is pretty close to the actual time it takes the Earth to make one full rotation, but that varies based on where the planet is in its orbit, a few seconds either way. The week has absolutely no connection to anything; a month is a variable unit of time that we just sort of guess at. […]

Greek orthography – Wikipedia

The orthography of the Greek language ultimately has its roots in the adoption of the Greek alphabet in the 9th century BC. Some time prior to that, one early form of Greek, Mycenaean, was written in Linear B, although there was a lapse of several centuries (the Greek Dark Ages) between the time Mycenaean stopped being written and the time when the Greek alphabet came into use.

Early Greek writing in the Greek alphabet was phonemic, different in each dialect. Since the adoption of the Ionic variant for Attic in 403 BC, however, Greek orthography has been largely conservative and historical. […]

Why do prime numbers make these spirals? – YouTube

Important error correction: In the video, I say that Dirichlet showed that the primes are equally distributed among allowable residue classes, but this is not historically accurate. (By “allowable”, here, I mean a residue class whose elements are coprime to the modulus, as described in the video). What he actually showed is that the sum of the reciprocals of all primes in a given allowable residue class diverges, which proves that there are infinitely many primes in such a sequence. […]
