Jingo, the angel's answer doesn't really make sense, unless perhaps any other question the man asked would have gotten him an equally useless response. Since the question turned out so badly, it couldn't have been the best possible question, could it?

Actually, that line from PM is just a statement of intent to prove later that 1 + 1 = 2. The proof itself is found 373 pages later, in Vol. II, p.86.

It is followed by a comment: "The above proposition is occasionally useful."

<ghoti> is a pretty terrible example of inconsistency in English. English spelling may be weird, but it has rules, and according to those rules <ghoti> can only be pronounced /'go ti/ (like "goatee"). Unless you can name a genuine example where initial <gh> is pronounced /f/ or where final...

The thing about spelling reform proposals is that they're usually ludicrous, in that rather than try to make words conform to the existing rules of English pronunciation they invent totally new rules and sometimes add totally new letters. A good and minimal spelling reform would maintain the set of ...

I'm not sure how you decided that
there is no complex number solution to sqrt(-i).

If you mean that there are no complex numbers whose square is -i, you are wrong; (sqrt(2)/2 - sqrt(2)/2 * i)^2 = -i and (-sqrt(2)/2 + sqrt(2)/2 * i)^2 = -i.

Undefinable numbers are uninteresting numbers?

It is the case that almost all real numbers are undefinable in the language of first order set theory. To see this, we need only note that the finite-length strings in the language of first order set theory are countable, while the real numbers are not. I feel it is reasonable to say that, while the...
