Sorry, Eric, but here I have to step in and defend Stephen Banard.
In my Theory of Computation class, we used Godel's theorem to prove
the halting problem, and showed them equivalent. It was the only
interesting part of the class (a class which pretty much reduced
itself to writing state graphs for Turing machines by the end of the
first trimester).
[Or at least, my fuzzy little head *remembers* doing this. It's been
a few years...but Godel certainly did show up. It was right about the
same time I read the book "Godel, Echer, Bach," and hurt my poor brain.]

Now here is where I stop.
Somehow he's decided that 'induction' and 'deduction' aren't even
kissing cousins. And as science uses 'induction' instead of 'deduction'
to arrive at the original conclusions, Godel's theorem doesn't apply.
A crock, to be sure.
But an amusing crock. Though dancing naked around the fire invoking
the Gods to come down from heaven and bless the dancers is certainly
a lot more entertaining.
