I was trying to do that just last night, and your solution is better than mine. > P.S.

Hmm, still seems like quite a coincidence. Maybe the meaning shifted from "paper" to the more specific modern meaning, due to him? I thought maybe I had the derivation backwards and maybe his family was in the mapmaking business (are French surnames sometimes derived from an occupation, as in the English "Baker" or "Smith"?) That could explain how he was led to develop the idea of a coordinate system. But then I found an interesting statement in an online biography <http://www.maths.tcd.ie/pub/HistMath/People/Descartes/RouseBall/RB_Descartes.html>: "His father, who, as the name implies, was of good family..." I'm not sure how to interpret that. An etymology at <http://www.etymonline.com/index.php?search=chart&searchmode=term> says that the meaning of chart as "map" goes back to at least 1571, just before Des Cartes bas born. -John __________________________________ Do you Yahoo!?
