History
Al-Biruni first subdivided the hour into minutes, , thirds and fourths in 1000 CE while discussing Jewish months.
Historically, the word "minute" comes from the Latin pars minuta prima, meaning "first small part". This division of the hour can be further refined with a "second small part" (Latin: pars minuta secunda), and this is where the word "second" comes from. For even further refinement, the term "third" ( of a second) remains in some languages, for example Polish language ( tercja) and Turkish language ( salise), although most modern usage subdivides seconds by using decimals. The symbol notation of the prime for minutes and double prime for seconds can be seen as indicating the first and second cut of the hour (similar to how the foot is the first cut of the yard or perhaps chain, with inches as the second cut). In 1267, the medieval scientist Roger Bacon, writing in Latin, defined the division of time between as a number of hours, minutes, seconds, thirds, and fourths ( horae, minuta, secunda, tertia, and quarta) after noon on specified calendar dates.
