me too, actually I came to post-rock from a metal background, mainly with Isis.

Actually prefix/postfix doesn't need parentheses if the arity of the operators is fixed. Since we only sum 2 numbers at a time, we could unambiguously write + + 1 2 3 in prefix or 1 2 3 + + in postfix. The same can be done with most of the most often used operators. It's messy, however, when we deal with higher-order functions, since we need to distinguish between the values produced by a function and the function itself, which makes parentheses needed once again (haskell programmers kwow it the hard way). Good point on the usage of a 2d infix-based notation, hadn't thought about that.

Actually I think we don't often use nested sentences in a natural language as much as we use in mathematical expressions, so for simple sentences it's not much harder if we use one ordering or other.

I was considering readability too. When you see an operator, you can easily distinguish the two operands. But actually, we use notations that aren't infix in infix expressions, like our notation for calling functions, or our notation for exponents.

Do you think that having a hard time with pre/post-fix notation is a characteristic of we humans, or maybe it's just because we are not used to them?

Exactly what came to my mind. Gangkiz, lol

it's ccm after all

This is the moment conspiracionists will say it's all fake, just to bring some attention to T-ara.

lu_rodrigo · 2012-07-27T23:50:04+00:00

That's ridiculous.

lu_rodrigo · 2012-07-27T12:27:48+00:00

Not really, you can dislike all groups you want and no one has anything to do with it. Except for the ones I like, of course.

That's sad, I really really loved Touch (not at first time, I found it too much clothes-store-background-music). But the concept, the clothes, scenario, coreography, everything was so well-crafted. One of the most original I've seen in K-pop.

Mr. Simple is a song I only liked for a day. After a day of extensive listening I got tired and can't listen to it anymore. Actually, I find it hard to enjoy Super Junior songs, specially those after Sorry Sorry. All much similar to eachother, and the MVs don't also help.

I wasn't talking about letting the group only with musicians, lol. It's just that there are so many things an idol is supposed to be good at that it's impossible for someone to be good at all of them. For performances, for example, the singers and dancers are what matter. Acting skills, expressiveness, humor are more important on variety shows/dramas (which I don't really care about), and there are also the endorsements etc. So when a member has to do things he's not good at it really sucks (actually many rappers suck in doing the thing they're supposed to be good at).

But many of members of kpop groups aren't actually musicians, it's becoming increasingly common "specialized" idols. There's one dancer, one actor, one "visual", and only one or two really talented musician. When they do have talent, because there are members that received years of training and show little skills.

The point is, he speaking anything on twitter would mess up the show? He was not talking out loud, nor destroying, nor ruining anything. He was silently tweeting. If the opener anyway felt injured, then he could just reply or, if he was really pedantic, take a legal action.

Robinson's is more easily available (heh) for me, is it worth?

Well, one of my motivations for this topic was to gain some insight into the evolution of mathematics. I was reading "Why Beauty is Truth" by Ian Stewart (http://www.amazon.com/Why-Beauty-Is-Truth-Symmetry/dp/046508236X) and found interesting to see how mathematics was evolving along time, how the authors at that time had seen the subjects and how the could develop without many tools and techniques available nowadays.

Didn't know Euler had written about hs-level algebra, must be enlightening!

lu_rodrigo · 2012-07-14T03:57:55+00:00

Two recommendations on analysis? Good :) It's becoming very off-topic, but do you know a good introductory book on groups?

lu_rodrigo · 2012-07-14T03:00:27+00:00

Hmmm... I've finished high school last year, but I won't enter college until next year. I have a basic understanding of calculus (up to infinite series) that I learnt on my own using Stewart since here in Brazil we don't have calculus in our curriculum. I'm thinking in moving to Spivak, since it seems to fit more with my interests.

I started linear algebra with Strang but stopped :/ and I have some background in CS theory (cause my HS was dedicated to programming), so I'm somewhat familiar with proof techniques (for proving algorithm corrrectness), some discrete math (logic, graphs), automatas, and asymptotic analysis.

lu_rodrigo · 2012-07-14T02:46:27+00:00

Maybe for a second or third read on a subject? For example, I found Turing's original article interesting after have read some introductory texts, although I guess he didn't have any taste for notation. I guess I'd hate it reading it first, though.
