Facts about 1/60th (sexagesimal systems):
Did you know until the 18th century, 1/60th of a second was called a "tierce" or "third"?
The reason we use angles like 30, 45, 60, 90 degrees, based on circles and globes being 360 degrees,
and why hours and minutes are divided into 60 parts,
and why coordinates are also divided up into 1/60th minutes and seconds.
… is because of the Babylonians. Actually it was passed down to them from the Sumerians who ( 5000 years ago!) had a base60 numeral (counting) system, unlike our base10 digits that we use.
60 is a “superior highly composite number”. It’s divisible by 1,2,3,4,5,6,…10,12,15,20,30,60. Thus having a base60 numbering system makes “dividing” things into 60 parts easier than 10 parts when dealing with fractions and rational numbers.
To think we’re still using the base60 accounting methods of Babylonian merchants to send satellites into space.
