i just took a call from someone who was arguing with a friend over whether the moon rotated on its axis as well as around the earth. i don't think i've ever had a conversation or argument that has led to me calling a large university to prove my point. i wish i did.
post script: oh, and for those who are interested in the answer, the moon does rotate on its axis. each time it circles the earth, about every 27 days, it makes one full rotation on its axis. the earth's tidal interaction with the moon slowed its rotation over many years to match its orbit around the earth.
post-post script: happy valentine's day.
