Al Bartlett from the physics dept of the Univ of Colorado, Boulder,
is a friend of mine who has for decades written articles and given
talks all over the country, including to the US Congress, about
exponential growth, population, and energy consumption. He teaches
us to be suspicious whenever somebody touts the virtues of growth (in
population, in energy consumption, etc.) He spoke in the law
auditorium at U Arkansas earlier this fall--some of you might have
heard him. His classic lecture, "Arithmetic, population, and
energy," is now videotaped and presented in 8 parts on the net. If
you don't know much about exponential growth, you'll learn a lot from
this video, even though it's "just" a classroom lecture. It starts
out a little slow, but soon presents some amazing (but true)
conclusions that arise from very simple arithmetic. When Part 1
ends, you can click below the screen on "Part 2" to continue on to
all 8 parts. Check it out at
