Named after an 11th-century Persian genius
“The Moving Finger writes; and, having writ,
Moves on: nor all thy Piety nor Wit
Shall lure it back to cancel half a Line,
Nor all thy Tears wash out a Word of it.”
— Rubaiyat of Omar Khayyam, trans. Edward FitzGerald
Omar Khayyam (1048–1131) was a Persian mathematician, astronomer, and poet. He solved cubic equations geometrically with compass and conic sections — centuries before Europe. He reformed the Persian solar calendar into the Jalali calendar, still more accurate than the Gregorian calendar. The compass in the app icon references both: the astronomer measuring the stars, and the geometer drawing the proof.
