stuff snipped

Physicists have already created matter from energy so the rules get very
fuzzy the more theoretical you get:

Why do things yellow and turn brittle under very bright light? Could
that
energy be converted not just into heat but into chemical changes of the
material it strikes?

How do plants create biomass from sunlight?

Don't CFLs create RFI which will pass right through the box?

What would happen if you lowered (inside a waterproof container, for all
you
wiseguys!) a tungsten bulb and a CFL of equal wattage into two
calorimeters?
Would they both raise the temperature of the water an equal amount? All
interesting questions - for a theoretical physics group.

As you point out, if I came to AHR to read about angelic pin dancing it
would have been a far more entertaining discussion, but as it was
written is
was wrong. At least if you believe in the common usage of the words
"put
out, exactly, heat and light" He meant "eventually" - a word that has a
pretty clear meaning which isn't exactly "exactly." (-"

That website is a wonderful resource and went straight to my favorites.
Thanks.

Well, at least SOME good has come out of this farrago of a thread. Have a
good friend who used to teach there. Trivia fans will note Urbana is
allegedly the birthplace of HAL in 2001.

I grew up in Urbana, and was HAL's[*] first employee (I was in high school).
;-)
[*] They make electronic keyers and other HAM stuff. Last I checked they were
still around.

Boy was that ever an optimistic movie. Moon bases, Pan Am in space. Pan Am
didn't even survive Earth! HAL was ranked No. 13 on a list of greatest film
villains of all time on the AFI's 100 Years... 100 Heroes and Villains.

Open the pod bay doors, please HAL . . .
