So it was! However, the idea to make something completely new and not to follow something existing did not result from political reasoning or from what countries they had a friendship with or not. The basic idea behind creating something new was: The new measures should make sense to EVERYBODY who was forced by law to make use of them and should therefore make it easy for everybody to adopt them. This reasoning is well backed up by other ideas falling into the time of the French revolution. For example: Since we all share mother earth it was decided that the meter should have a definition that is based on the size of earth. So the original definition of a meter was to be 1/40000 of or earth's circumference. This lead to a minor problem: Earth's circumference was not well known at that times. Which in turn lead to the invention of a new class of surveyor instruments, which in turn enabled the French to measure the distance from the equator to the north pole (assumed to be 1/4 of the circumference) with a precision that must be admired even from a today point of view. I do not know the english term for it but in German these instruments are called "Repetitionskreis". You can find a pictue of one here: http://www.bistumsmuseen-regensburg.de/html/ausstellungen_moenche_repetition skreis.htm A very good literature about this topic is Ken Alders "The measure of all Things" Best regards Ulrich Bangert > -----Ursprungliche Nachricht----- > Von: [email protected] > [mailto:[email protected]] Im Auftrag von steve gunsel > Gesendet: Freitag, 21.
