I can not resist stealing from ZNFYRH to start this thread. The original post is in Metaphysics and God. What is the cause of a one meter long object completing a pendulum swing taking in one second?

Posts: 3,627 We are, actually, measuring matter with our current system of time.

1 second is exactly the length of time it takes a 1 meter long object to complete a pendulum swing.

It is, ironically, an arbitrary length of time and, magically, it takes 86,400 for a complete day.

Which makes me wonder how the Babylonians came up with a calender, with 24 hour days, divided by 60 minutes? What did they know to come up with this calender?

Numbers in Ancient Babylon
The Babylonians had a calendar, with the days divided into 24 hours, where each hour was divided into 60 minutes, and each minute was divided into 60 seconds. This form of counting survived for 4000 years and is still used today all over the world.

Ancient Babylonians used a what's called a sexigesimal (or base 60) number system as opposed to the base 10 system used today. In a base 60 system, all the numbers are categorized in groups of 60s. This means that whenever a unit of a number is moved to the left, its value increases by a factor of 60.

As a more specific reference to this... to be frank... amazing coincidence...

A one-meter pendulum has a period of two seconds.

My heart is racing. You have really excited me. Thank you. Now darnit, I have to run. Can you provide the name of a book that information?

Book?

No.

But nearly every reference to making clocks includes this information.

Physical Time, as we know as Sec. and defined under the reference mentioned by Athena, has very solid dependant as gravity (g)in addition to length as 1 m. You change g for a given length, 1 m the time would not remain as 1 sec. 1 m length string would not take 1sec. earth time on moon or under vacuum !!!

Metaphysically time, has sinificance with reference to the perceptor viz, the person and the state of mind he is in. Same amount of physical time would appear very long if he is under distress while; very short if he is comfortable situation. More correctly, time (metaphysical) is only some infinite PRESENTs !!!
