This little panel from Bill Watterson’s Calvin and Hobbes appeared on facebook last week, and it totally nails the motivation for Bicycle Astronomy and other public outreach projects. Look up more. (Or look under rocks more.) Live better.
Edited 1/1/14: I found the entire strip that the original panel was drawn from. I like the rhetorical power of the single panel, but I like the full strip, too, because it so gently suggests what we all might profit from doing a little bit more of.
