Good Sir, your argumentation is flawed. That's rather like saying that without raw eggs there wouldn't be any cake, therefore raw eggs own cake. Yet I am sure that we all agree that we would feel slightly disappointed when, come dessert, we were served raw eggs.

That's the best allegory I've ever heard for anything. What a shame it's wrong.
Just because we like the taste of cake more than that of raw egg doesn't mean cake owns raw egg. The purpose of cake is to be eaten; the purpose of raw egg is to make up for the fact that it never became a chicken by existing. If the two were in a fight, the raw egg's insides would end up over the cake, rendering it inedible. Result - raw egg godpawns cake every time.
My head hurts.

I'm afraid it is you who are wrong, my friend. The scenario you describe is impossible, as both cakes and raw eggs are non-sentient, immobile objects without the ability to fight each other. Furthermore, since you are so interested in so-called purposes: It's neither the purpose of cake nor raw eggs to participate in fights, therefore the outcome of a so-called "fight" between the two is irrelevant to this discussion.

You should become French and rule the world with us.

I am nationless - and I likes it that way. Thanks for the offer though

EDIT: You're probably not talking to me. Sowwi.

Yes I was, but it seems you leave me no choice...

(well Raylex's an exception ) !

Yeah, but he does have more powers than English mods.

Yup, but his powers will be mine.

No choice about... what...?

Physics studies a lot of very interesting concepts, to which maths is often applied; same goes for computer science, chemistry etc. Maths is the "root of awesome", if you will... now what is it based on? Pure human thought, power of the brain... Physics is too, but not quite as much, I believe.

Yup, but his powers will be mine.

When though?

[Raylex]

Because we're way awesomer (well Raylex's an exception ) !

Agreed there.

You can't agree with this jerk! God dam' yal!

[DesLife]

Of course they can.
Plum : soon.

[Jewish Candy]

I was under the impression he was complimentin' ya. You're a global mod, right?

[DesLife]

Ahah I love teasing him. Yup, unfortunately, he's a global mod.

Yeah, I'm the boss
DesLife is just a Iznogoud-like idiot!

[Jewish Candy]

Yeah, I'm the boss
DesLife is just a Iznogoud-like idiot!

Aww, harsh... still, if you're the boss you have a right to say whatever.

[DesLife]

Yeah, I'm the boss
DesLife is just a Iznogoud-like idiot!

Just you wait, you silly Caliph.

[PluMGMK]

Plum : soon.

Ah, but how soon is soon?

[Acarr]

Anyone good at biology here...?

Which of the following processes requires infolding (?) of the cell membrane?

1. Diffusion
2. Phagocytosis
3. Active Transport
4. Osmosis

[Rayfist]

A topic for HOMEWORK HELP!? You guys are the coolest. I start school soon.

[DesLife]

Plum : soon.

Ah, but how soon is soon?

6 months.

Instead of posting this in the You Game, because I'm sure no one is interested in this awesome convo, I suggest we continue here, mat.

Code: Select all

bool is_prime(int n)
{
	int start = 5;
	if (n==1)   return false;
	if (n<4)    return true;
	if (n%2==0) return false;
	if (n<9)    return true;
	if (n%3==0) return false;
	while (start <= sqrt((double)n))
	{
		if (n%start==0) return false;
		if (n%(start+2)==0) return false;
		start += 6;
	}
	return true;
}

I guess % stands for mod. What's ((double)n) though ? And start +=6 means start:=start+6 I assume. So you reduce the number of calculations needed.

[Matyuv]

% stands for mod yeah.

(double)n is just a type conversion from an integer to a floating point number (so called "double"), because sqrt() doesn't take integers as arguments. It's a language technicality that has nothing to do with the problem itself...

start +=6 means start:=start+6 I assume

Yeah. I'm using the fact that all primes over 3 are of form 6k+1 or 6k-1.

I wonder if there's a more efficient way to do this..


btw orsum bump.

[DesLife]

because sqrt() doesn't take integers as arguments.

Ahahah that's stupid.

Yeah. I'm using the fact that all primes over 3 are of form 6k+1 or 6k-1.

I didn't know that ! Now this program makes perfect sense. And it seems good, but I'll do some research about such functions.

Btw, what have you studied this year so far ?

[Matyuv]

Vector calculus, functions of a complex variable, complex integration, series, function series, binary relations, boolean algebgra, graph theory... That's it, I think. You?

[DesLife]

Some new stuff about algebraic structures (like ideal rings), normed vector spaces, integration, series, function series, power series, diagonalisation and trigonalisation, Fourier series, multivariable calculus, pre-Hilbert spaces.
