It seems like a stretch but is there any chance

Imps as can't be seen or heard or remembered, even while they're eatin' yer face.

is a shout out to

But just because you're paranoid doesn't mean that there isn't an invisible demon about to eat your face.

from the Dresden files?

Also could the spell Quirell used to destroy Hogwarts walls in earlier chapters be used to dungeon bypass the third floor corridor by going through the back of the room with the mirror of desire Erised>

It's probably a reference to Worm (which has a character called Imp whose superpower is to selectively stop other people from noticing or remembering her).

I've just read "Hell is the Absence of God" by Ted Chiang, and upon finishing it I was blown away to such extent that I was making small inarticulate sounds and distressed facial expressions for about a minute. An instant 10/10 (in spite of its great ability to cause discomfort in the reader, but hey, art =/= entertainment all the time).

I'm compelled to link to a html mirror but I suppose it hasn't the author's permission. Anyone who'd like to read the story now may look at the first page brought up by googling the title. This is the book in question.

I'm curious as to the opinions of those who have read it.

I think people on Less Wrong might enjoy my personal favourite Ted Chiang story "Understand", about nootropics. It's also been made available in full on Infinity Plus with permission, here: http://www.infinityplus.co.uk/stories/under.htm

I want to learn enough measure theory to deal with theoretical papers on stochastic processes e.g.(warning: pdf). I need a text with lots of homework problems. Suggestions?

Disclaimer: I am not a probabilist.

One possibility would be some combination of the book Probability With Martingales by David Williams, and the lecture notes of James Norris available freely online here and here, depending on your taste. As the names suggest, both of these develop measure theory with probability theory in mind. Section A of Williams's book and the first set of Norris's notes cover basic measure theory, and sections B and C of Williams's book and the second set of Norris's notes cover more advanced topics (conditional expectation, Martingales, Brownian motion). I'm only really familiar with the former, not the latter, and depending on what exactly you need/want to know you might only work through the former, and maybe not even all of that.

Norris's notes in both cases are quite a bit terser and cover a little more material. Both the book and the notes have a large number of very helpful exercises compiled at the end. I remember finding some of Norris's exercises in particular a lot of fun!

Other books I'm aware of: D. H. Fremlin has an encyclopaedic set of volumes on measure theory available for free on his website here. I've found this useful as a reference. Some people like Rudin's Real and Complex Analysis for this kind of thing, but I wouldn't recommend it for your goals. (It's very difficult to jump into that book in the middle: you really need to follow the garden path from beginning to end, and I think that'd force you through a lot of functional analysis that you could survive without). Folland probably suffers from similar problems, but I'm not really familiar with it.

Good luck!

Because I am not a Meat Fucker.

Ok, I don't get this. Is this an allusion to something?

Comment author: chris_elliott 11 October 2010 11:11:09PM 19 points [-]

In Ian M Banks' novel 'Excession', the term meatfucker is used as an derogatory term for AIs that violate a cultural taboo again reading human minds.
