Re: Consequences to P=NP

I don't know if there really would be any difference. There may be a way to solve 3-SAT given, say, a 200-dimension dynamic programming table, or by an algorithm that runs in n^100 time. Still "polynomial," but that's sort of irrelevant. Even if P==NP, it is highly unlikely that we could f...

Re: Working with Alice

In the second semester of the class we did Java programming which was fun and interesting but we never had a chance to use our creativity to go above and beyond the assignment. Well, I would argue that not being able to go beyond the assignment is not an issue with the language, but with the course...

Re: The Dark Tower series?

To those talking about the ending: I think it's almost the opposite! The most important thing for me was the fact that Roland has his horn in the "next" iteration. I think that represents a potential for redemption, since he always said that he missed the horn, and I seem to remember t...

I'm in the "wouldn't it be awesome to be a linux guru" phase (which is followed by a "ooooh, look over there!" phase in which I forget just how awesome it would be (pretty awesome)), which means I checked a book about linux out of the library, and I'm reading through it. In it, t...

Re: The Dark Tower series?

I found the first one in the series (and books 2-4 to a decreasing extent) to be the only real worth-while one, stylistically. It took me way too long to figure out how to spell that word, anyway, in the latter books, it starts to read like any generic book ever, with King losing his voice and perso...

Again, not exactly physics, but I've been thinking about getting Godel's Incompleteness Theorem for a while. Problem is it's a long one. Maybe wound around a forearm?

Oh, sorry man, wasn't trying to question your knowledge about it, just thought it was cool that you seemed to be a doctor or something along those lines, mostly 'cause it put your name in a new light. Also was definitely not trying to be creepy. Apologies. :)

Re: Odd Multiplication Trick on your Hands

Is it just me or is mental math/memorisation way easier than this? WAY easier. I said my teacher taught it to me, didn't say that I ever used it. Say you are multiplying x * y, with x and y both between 6 and 10 inclusive. Then the trick you're performing, if you work it out, is simply calculating ...

Odd Multiplication Trick on your Hands

When I was just learning multiplication way back when, I had a huge problem with those "mad minutes" that my elementary school teachers would give me (you know, the ones with about four brajillion simple multiplication problems, which all had to be answered in under a minute?). Anyway, my ...

Re: Eating Chalk?

Yes, just because something is ionic does not necessarily mean that it will be highly soluble. especially with the carbonate anion, whose solubility constant tends to be pretty low, I think (I don't recall the exact number or even a more specific range, chemistry was a long time ago). However, even ...

Re: Eating Chalk?

Cool, thanks. Yeah, I figured that it probably wasn't the best calcium substitute.

Another question: tea. To get the nutritional content (such as the anti-oxidants, or whatnot) why does it have to be steeped? Couldn't you just eat it? Wouldn't taste very good, but whatever...

Eating Chalk?

I know that (pure) chalk is calcium carbonate, which means that it has calcium ions. Since it's ionic, it should break up in water, which is rather plentiful in our stomachs. Does this mean that we could get calcium from eating chalk? A friend, reading my post, says that a person looking at this wou...

Re: I'm done being afraid of calculus

What is the difference between f(y) = y+1, and g(x) = x+1? Well, depends, we talking the Cartesian plane here? Or just any old x and y variables? As in, is this question the same as asking what is the difference between f(a) = a + 1 and g(b) = b + 1, or is this more specifically bound to the x-y pl...

Re: TNT(not the explosive)

All I can say is what is in GEB for that chapter, but he mentions what you're asking about. He (Hofstadter) says that there are two types of statements in TNT, closed statements, in which every variable is quantified, and thus can be "true" or "false", and open statements, in whi...

Re: TNT(not the explosive)

So then, what's the rule about order of operations? I mean, TNT is supposed to be a formal system, so I feel like there's gotta be a more formal rule.

Re: TNT(not the explosive)

Question about order of operations in TNT. On page 212-3 of GEB, Hofstadter presents six formulae in TNT notation, and says that the problem is to figure out whether each one is true or false. One of them goes like this: Ac: ~ Eb: (SS0 * b) = c. That, to me, means that for every "c", there...

I'm not entirely sure if that's a good or a bad thing. I got it for Christmas (thus this strip made me oh so ...
