why a clock enjoy only12 hours?
the 24 hour day is base on a mathematical relationship on the subject of the rotation of the earth. (This is one and the same concept that can explain how and why radians and degrees are used within trig measurement.)
Clocks usually hold 12 hours on them because this makes it easier to show the minutes and second in between respectively hour, as opposed to have 24 numbers. The angles make by the hand seem more defined contained by a 12 hour system than in a 24 hour system.
Telling time is a ocular process, so the clearer the clock is...the faster and more efficient this will be.
WRONG SECTION
And how should i know? Because if you put adjectives 24 it will be too full and too hard to read!
Economy of space. Why crowd adjectives those numbers when you can just enjoy the hands dance around twice. Obviously you know whether it's night or sunshine.
definition
we define a second be a sure number of vibrations of a cesium atom
the original counting systems (babylon era) be all stand 60, which went resourcefully into an hour. it's also a multiple of 12 (12x5=60)
we've got 3 joint on each finger (3x4=12) near 5 fingers a hand (again, 12x5=60)
We're not really sure why they chose 60, or why we use 10 (computers use 2 and 16 as bases) but that's the approach the history of math was built.
dunno... only just imagine if we own 100 hours in a clock..
No one know why exactly, but the reason they are resembling that today is because ancient sundials and water clocks consisted of 12 hours. One of the theory's as to why to be precise, is because they had to equally divide the sunshine into sections. I don't know why they chose 12 though.
