Today's History Channel calendar is very relevant to TG2 fans -

"Eratosthenes, a Greek academic, was the founding father of geography.  He invented the system of latitude and longitude and, on this day [June 19th] in 240 BC, offered up the first measure of the planet Earth.  Modern mathematicians approximate that his calculations reflected a size of 25,000 miles in circumference, only 98 miles more than the modern value of 24,902 miles."
So this is Disney World.  Can we live here?

yea I know, pretty crazy how smart some people are. (I have it on my calender)
The world is round... so you have to use spherical projection.

Yeah, 2300 years ago a Greek mathematician calculated the diameter of the earth with less than .4% error.

About 5 (10?) years ago, NASA slammed a probe into Mars, accidentally destroying it because they hadn't (couldn't?) converted distance from metric to English units.

Still think we're getting smarter?

;D

Note the word some. Though I wonder if their heads were bigger back then. (Idiocracy plug)
