“I never did anything with it, but always liked the melody. The words were silly, anyway,” John admitted. “I sang it to Yoko, Phil Spector and a few people and they always winced. I decided to change it – and with Yoko’s help, I did…”

I think it takes a lot of chutzpah and no small amount of naivete to think that some new algorithm is what stands in the way of students solving quadratic equations.

This is just simply the best thing I’ve ever posted on here.

I find it even sadder as a rewrite of "Child of Nature," a frankly beautiful and tender song. On reflection he decides that this isn't really who he is, he's just a jealous guy.

Yeah frankly the more I think about it I like that story better also.

I will now prove this. PROOF: by authority

Yeah, I get that. Where I disagree is I don't think Godel ruled out inconsistency. What is undecidable from the perspective of the theory P is the statement Con(P), IF P is consistent.

I am feeling reasonably confident that Godel could not have ruled out that a contradiction will appear in arithmetic, because that is synonymous with ruling out inconsistency.

Godel #1: Every axiomatic theory of arithmetic contains theorems that are true in the theory but aren't consequences of those axioms. Godel #2: Even if this axiomatic theory turns out to be consistent, you can't prove it as a consequence of those axioms.

I need to hit the books -- that was not my understanding of the 2nd incompleteness theorem. A constructive proof of inconsistency (I thought) would simply be a discovered contradiction. The 2nd theorem doesn't safeguard against the possibility, does it?

It's one hell of a formalism, is the point.

Well then clearly part of this new formalism she invented involves falsifying Godel's Theorems!

Fun read about how my friend translated Harry Potter in Yiddish—imparting a lomdish accent to Dumbledore, Litvish to McConagall, and a deep backcountry Polish voice to Hagrid:

Maybe I'd rank Evolution of Human Science higher. Not sure! Time to read his new collection...

Disenchantment shows up in a lot of these stories. Losing faith in math or someone else. Whether science would be still meaningful in a world of super-human intelligence. Whether you ought to elect to disenchant yourself of the effects of beauty. So clever, so melancholy.

Though the math is cool, and I'm always to see more cool math getting around.
