Why does a second last a second?!
Question: Why are there sixty seconds in a minute? sixty minutes in an hour and twenty four hours in a day?
Yes I know the earth turns once on its axis every 24hrs and travels once around the sun every 365 and a bit days, but why such random numbers and divisions and who decided?
I just thought it was an appropriate question at this moment in time, however long a moment lasts.
How am I doing snake eyes? (smile)

Wiki saids:
The origins of 'time' go back to the Sumerian civilization of approximately 2000 BC. This is known as the sexagesimal system based on the number 60. 60 seconds in a minute, 60 minutes in an hour – and possibly a calendar with 360 (60x6) days in a year (with a few more days added on). Twelve also features, with roughly 12 hours of day and 12 of night, and 12 months in a year.
idk
there is no reason.
I don't know.
Because there are, I suppose!
Live for and in the moment and enjoy it while lasts. When you get too mathematical, things get very frustrating. Tonight, no math nor books. Cheers (water bottle) and Happy New Year!
"A sundial described in 1300 BCE reveals that the Egyptians determined a daily cycle to be made up of ten hours of daylight from sunrise to sunset, two hours of twilight and twelve hours of night. Their calendar year was divided into 36 decans, each ten days long, plus five extra days, totaling to a 365 day year. Each decan was equivalent to a third of the zodiacal sign and was represented by a decanal constellation. The night corresponded to about twelve decans, half a day to eighteen decans. Similar to the system used in Oriental clocks, the night was thus divided into twelve hours, with seasonable variations of the hour's length. Later, Hellenistic astronomers introduced equinoctial hours of equal length.
The Babylonians (in about 300-100 BCE) performed astronomical calculation in the sexagesimal (base-60) system. This was extremely convenient for simplifying time division, since 60 is divisible by 2, 3, 4, 5, 6, and 10. What we now call a minute derives from the first fractional sexagesimal place; the second fractional place is the origin of the second."
Cause you are stupid!How can you make this questions?!Are we God or what?!
it is not random people have given this alot of thought count it it is correct if you break it down it is correct to the last seconed cept for that 1/4 of a day each year which gets added to february every four years
Matters of time and calendars were devised long ago.
However, all those measurements are still man-made concepts. This is why it's always so ludicrous to ask someone "Do you feel older?" on their birthday -- nothing in their life has physically "clicked" to indicate he/she is one year older. Actually, calendars were invented solely to tell farmers when to plant and when to harvest.
Errrm, I see dead people...

im wondering thesame thing
Well yah see, it was all because of a sundile. The end. =]
Because if it lasted a minute - it would be a minute.
