Why are there only 60 seconds in a minute ?

A minute is a unit used to measure both time and angles. A circle was divided into 360 degrees by ancient civillisations, probably Babylonians who figure everything in units of 10’s and 60’s instead of 10’s and 100′ as we do. The degree was divided into 60 parts and each of these parts was divided into 60 parts. The Romans called the first division of the degree ‘the partes minutae primal’ on the first part. The second division they called ‘the partes minutate secundaes’  or second small parts. These terms were finally shortened to minutes and seconds.

Why don’t clouds with millions of tons of water in them come crashing down ?

This velocity is smaller radiuse of a fluid particle or crystal. Actually it’s quite small for drops the size of a few millimeters and so, althought the drops in a cloud fall, they fall so slowly that only careful measurements would reveal the fact. © Susan Serebriakoff, Antwerp, Belgium) The weight of the water is distributted over a very large volume. So the density is actually less than that of air. In fact, the water is in the form of vapour which is lighter than air. This comes crashing down when it gets cooled and converted to water.
