Units of measurement are totally arbitrary, what they are measuring isnt. It
is irrelevant how long a second is as long as everyone agrees. Time has
nothing to do with the existance of cesium. The origonal basis for the
second was the roatation of the earth but that is not constant so it was
redefined I believe in the 60s, seems like I remember hearing about it in
HS.



Jimmie:

There is much common sense in what you state.

However, I see us at a point where no more real advances in knowledge
can be made until we do have an understanding of what these arbitrary
units ARE measuring--at present, all we really understand are our units ...
