Because when no one tells Andrew to come in out of the rain he gets wet and when
he gets wet he would conduct electricity. ;)

Actually, the only episodes I enjoyed were the ones that weren't about
UFO's and aliens.

Yes, but why 101? Why not 100? (I've occasionally seen a 100 course,
but 101 is much more common).

Because most normal people start counting at one?

Maybe the first unis that did this figured people were Pascal-based
rather than C-based. (Pascal, IIRC, starts arrays at '1', C starts at
'0').

That would be most of the episodes, I guess. The so-called
"monster-of-the-week" episodes. They are still fillers.
I also enjoyed immensely the meta episodes poking fun at the series itself.

Couldn't agree more. And I feel better now. It comes on in about 40 minutes!

Also by convention, 100 is the last (if available) of the remedial
courses for a topic.
101 isn't usually the "for noobs" section, but rather the "first course
appropriate for college" level.
If you've failed to master high school material, then you'll probably
have to go through 60, 70, 80, 90, and occasionally a 100 course to make
sure you can handle the college courses.
At least, that's the theory. In reality they often get weird numbers
(like 126 being the first course in a series, or 110 the first of another).

> Why do overhead cables never flap around in the wind?
Actually they do, it's just it's usually very fast and very low amplitude
flapping. Imagine holding out a stretched violin string in the wind, it's
not really going to flap is it?
Anyway, take 200 metres of this stuff (which I make weighs 10 tons):
http://www.csunitec.com/saws/new-river-band-saw.html
pull it *very* tightly between two points (I estimate you're going to need
at least 60 tons of tension in the cable), and then put it in the wind, I
can't see it flapping about too much personally. Some of the really long
cables have dampers on them to get rid of the main resonant frequency, a bit
like what they put on the Millennium Bridge in London to stop it resonating
at the frequency people walked at.
> Come to think of it, why doesn't rain short out power cables?
Because air with rain in it is still an insulator?

Lots of things have higher melting points than most steels. Ceramics for
instance.
