This lecture was to be about the Earth's atmosphere, its composition and
structure, the greenhouse effect, and the primordial atmosphere, but
about 2 seconds into the lecture, unbeknownst to me, the battery
compartment on my digital voice recorder came open in my pocket. At the
end of lecture, I took it out of my pocket to turn it off and the
battery didn't come with it. Oops! Fail. My apologies, I'll put in
some work to prevent a recurrence in future lectures. Recorded live on
2009 Oct 6 in Room 1005 Smith Laboratory on the Columbus campus of The
Ohio State University.
