One thing I have known since I was a child is that 60 seconds is 1 minute
60 minutes is 1 hour.
Why 60?
Why not 100? I think you may have thought about it.
How do teachers respond when a thoughtful student asks?
This system of calculations, based on the 60's, was first used by the Sumerians around 3500 BC.
Circles and triangles are shapes that can be calculated by 60.
This system was continued by the Babylonians and was used in mathematics and astronomy.
The method based on 60 is called sexagesimal.
In ancient times, day and night were used as clocks and clocks. Look at the stars
It was calculated.
The ancient Egyptians set day and night as 24 hours.
It is set at 10 o'clock in the day according to the shadow of the sun. Added before and after 1 p.m.
The night is set at 12 o'clock by looking at the stars.
A total of 24 hours.
These are the numbers that can be divided by sexagesimal (6).
The Greek astronomer Hipparchus first defined 60 seconds as 1 minute.
Dividing one hour into 60 parts by sexagesimal arithmetic is called the "Prime Minute".
From that small minute became minutes.
Dividing the Prime Minute by another 60 results in a second part, called a "second minute."
From that second second to seconds. (There are also Third Minute and Fourth Minute.)
The clock we are using was written by a Dutch astronaut in 1656
It was invented by Christiaan Huygens.
But he used a pendulum clock.
Later, his watch design became widely used in various ways around the world.
