Why we count things and how we measure them

Time: 1 second, 60 seconds = a minute, 60 minutes = an hour.
12 hours = one day. 30 days = a month. 12 months = a year. -
Geometry: Both two- and threedimensional geometry are derived from base 60 matemathics – the 360 degree circle gives us all the angles and formulas for creating virtually every shape known.
-
Amounts: 12 eggs in a dozen, 12 months in a year, 12 inches in a foot and 12 signs of the zodiac.
12 disciples of Jesus. -
The 12/60 based mathematics comes from the Sumerians in Mesopotamia 5 000 years ago. They counted the knuckles on the four long fingers of the left hand (12) and multiplied that by the number of fingers of the right hand (5) – 12 x 5 = 60.
Pythagoras, numbers and music
