Re: "Simultaneous" Discussion

Strangely enough, I didn't get the SR joke, read the alt-text, got that THAT was a SR joke instantly, but somehow completely failed to connect SR to the main comic...

Re: The Rubiks Cube

As someone who has no mathematical insight to provide as per Rubix cube, I have a practical solution. Why not just put walls between the contestants up? Then everyone can see then, they can see the audience, but not each other. Unless there's some specific reason they all need to see each other? It ...

Re: Georgia Tech

Since the topic's already here, I'm probably applying to GaTech's mathematics PhD program. Is anyone in that, and how is it? And how female-friendly is it? Thanks!

Re: Rock Paper Scissors

When I was younger, I could beat my sister by going backwards on all but the first time. She didn't realize she was consistently picking whatever would beat the last thing I played. So that was fun! We were kind of young, though, so with adults probably random is best, unless you kind of know the pe...

Re: "Fetishes" discussion

Kickass awesome; I laughed so hard my stomach hurts. And now I feel a smug sort of pride; after not getting countless CS comics, finally my Logic minor enables me to get the joke without looking things up first!

Re: Linear algebra problem

I haven't taken linear algebra in a bit, so does |z-3| mean each value in the vector z has 3 subtracted from it, and the length of THAT vector equals 2? I would guess so, but just checking. At any rate, if a vector is an eigenvector, all multiples of it are eigenvectors too, so I'm not sure how the...

Re: What's wrong with this proof that no two numbers are equal?

Even if the proof made sense (in the way that I think you mean it) all the proof would show is that if you pick two random numbers from the set of all numbers, the chance that they'll be the same number is virtually zero...sure, I'll grant that.

Re: Something I've been wondering since 7th grade

Doing "+1" on x y times gets you "+y", but I think you mean plugging x into both sides of a binomial operator, so x$x$x...(y times) equals x + y. I suppose if we want to be cheap we could define "a$b" as "a + b^0" (or a +1). Doing that y times equals x + y.

Re: What direction am I heading as an undergraduate?

I'm kind of like that, too-I get lazy if a course isn't really challenging me to think. Got straight Bs in Calculus until multi-variable Calculus, which is why it took me a while to realize math really was my thing. I really like problem-solving when the problem is kind of clever, it's like how ridd...

Re: How do these punks do it?

I took a proof-based version of Linear Algebra (Infinite Dimensional Linear Algebra), and it was exhilirating. No textbook, just every week was, "Here, prove that a matrix A is injective if and only if Ar=0 has only the trivial solution" (that was the second week). I had to work harder at ...

Re: Logical fallacies/douchebaggery in commercials.

How has no one mentioned the Dominos "You got 30 minutes!" ad campaign? (Has someone mentioned it already? I'll be embarrassed). The general format is, a deliveryperson shows up with a pizza, and someone looking or sounding fairly ridiculous for whatever reason answers and says, "Gues...

Re: Always False Algorithm

This is almost certainly not what you're talking about, but I was reminded, so what the heck. There is a card trick where a large number of people each draw a card and hold it up to their forehead, so they can see all cards but their own. They then guess whether they have a black or red card. If the...
