I don't understand at all the arguments against the metric system and
the polemic remarks about. I second the statements of Neville and Jim.

Without these intelligent french Astronomers like Jean-Baptiste-Joseph
Delambre, Pierre-François-André Méchain and J.J. Lalande (more infos:
Ken Alder, The Measure of All Things), we would still have the severe
problems they had centuries ago!

Reading WIKIPEDIA, http://en.wikipedia.org
/wiki/German_units_of_measurement,
we find a good example of weird units (just for only a part of Germany):

"Before the introduction of the metric system in Germany, almost every
town had its own definitions of the units shown below, and supposedly by
1810, in Baden alone, there were 112 different standards for the Elle
around Germany. The metric system was a much-needed standardisation in
Germany."

This was not only a german problem, and we still have today some
problems in the world in this area.

I believe we should think more about what we are saying and doing, so we
would do a big step forward to become a world community. ...

Sorry for this personal opinion and comments,
let us come back to timing problems with scientific and technical
discussions,

regards,

Arnold
