Hi,
In adition to the meter, also the platinum kilogram is in Paris.
Although recently it was found that it has lost some weight
(compared to its brothers and sisters in other locations)...
Wasn't the official definition of the meter also tied to Paris?
_______________________________________________
The original measurement was done on a meridian from Dunkirk to Barcelona,
based on the assumption that the Earth is rotationally symmetric. But like all
good projects, that measurement effort made clear that its fundamental
hypotheses were false (that the Earth is rotationally symmetric and that
careful measurements could be done essentially without error).
Dale
Regards, Huub.
