Editing Minute and second of arc (section)

==History==
The concepts of degrees, minutes, and seconds—as they relate to the measure of both angles and time—derive from [[Babylonia|Babylonian]] [[Babylonian astronomy|astronomy]] and time-keeping. Influenced by the [[Sumer|Sumerians]], the ancient Babylonians divided the Sun's perceived motion across the sky over the course of one [[Solar day|full day]] into 360 degrees.<ref>{{cite web |title=Why is a minute divided into 60 seconds, an hour into 60 minutes, yet there are only 24 hours in a day? |url=https://www.scientificamerican.com/article/experts-time-division-days-hours-minutes/ |website=Scientific American |publisher=SCIENTIFIC AMERICAN, a Division of Springer Nature America, Inc. |access-date=25 July 2021 |date=March 5, 2008|author-first1=Michael A. |author-last1=Lombardi}}</ref>{{Failed verification|date=December 2023}} Each degree was subdivided into 60 minutes and each minute into 60 seconds.<ref>{{cite journal |last=Correll |first=Malcolm |journal=The Physics Teacher |volume=15 |pages=476–479 |issue=8 |date=November 1977 |doi=10.1119/1.2339739 |title=Early Time Measurements}}</ref><ref>{{cite journal|journal=Journal for the History of Astronomy|author-first1=F.
