From a previous revision:
- The speed of light is believed to be constant everywhere, and thus a definition based on light is easier to maintain and more consistent than a measurement based on the circumference of the Earth or the length of a metal bar.
Good concept, but I can't see how to integrate it nicely in the History section. Anybody?
Perhaps we should have a page dedicated to the history of the metric system (itself rather fascinating). From there, one might explain how and why the different measurements were chosen. --

- Since the speed of light is believed to be constant everywhere, a definition based on light is easier to maintain and more consistent than a measurement based on the circumference of the Earth or the length of a specific metal bar. Thus, should either object be destroyed or lost, the standard meter can still be easily recreated in any laboratory.
LOL! Destorying or losing the circumfrence of the Earth! (Made it less humorous now.) -- SJK
- drat, I shouldn't have drawn attention to the article again with that little edit. I was wondering how long that joke would last in there. :) -BD
