..."I think, therefore, I am"...
That's funny.
I used that quote in a class yesterday while we were discussing geometry.
It's by Rene Descartes, the first person to describe carteseian coordinates ("cartesian" comes from his last name).
My Christmas stuff has been down for a while, but one of my neighbors still has the whole nine-yards going on with tree, lights, decorations, etc. I guess they are "hanging on" to Christmas as long as they can.
