Re: What-If 0123: "Fairy Demographics"

Footnote [6] ignores the possibility of fairy truthers. Clearly all this "well-documented" evidence about fairies is just a false flag operation.

Almost certainly. But this is England. Downton was probably named about 1000 years ago. Upton might as well be an archaeological site by now.

Re: 1005: "SOPA"

I'm not sure this is comic 1005, it's more like "Not Comic 1005". People said the same about http://xkcd.com/404/ - but that shows the blackout banner, whereas http://xkcd.com/wghmfdmf shows a 404. So I think that means that 404 is definitely a comic, not a missing comic.

Re: Cantor's Diagonalization Proof

But the version I've seen attempts to the put the positive integers in 1:1 correspondence with the reals. Accordingly, using the diagonalization method, you can show that at least one real number is missing from the right side of the list. After showing this, a person might say "just match the...

You seem to be assuming that because hurricanes involve the movement of air particles, that any given air particle can be part of only a finite number of hurricanes at a time.

Re: target practice -am i misunderstanding the question?

Your arithmetic is right, but the way the prizes are structured seems odd - if you hit 1 or 2 targets you win a prize and get a fine. Are you sure it's not a $100 fine for missing all targets, not just 1 target? Then you get a more sensible answer.
