heh... algebra...  needs more dirac deltas, THEN SHIT GETS REAL!

That much? Thanks to Laplace, I didn't think it was that hard...

I... this... you don't get what a dirac detla is, right?

Seriously, we're talking about maths now. You can't make jokes like that.

[/quote]I'm an Engineer, of course I know what a dirac delta is. I was just too lazy to insert a reference to something that would make the XKCD strip actually contextually appropriate, assuming noone would try to call me out on it.

The dirac delta function, otherwise known as the 'unit impulse function', when expressed as a function of time ( δ(t) ) is a function which has infinite height, zero duration, and a very clearly defined area (or infinite integral, if you prefer) of 1. It has a value of zero everywhere except at zero, where it is discontinuous in the positive infinite direction. Therefore, it is commonly graphed as a line with an arrow pointing vertically, with the location of that point being the area ( ex. y=δ(x) would have an arrow at (0,0) pointing to (0,1), showing that the dirac delta function has an area of 1, as it is defined to). It is exceptionally useful both in signal analysis and in mathematical deconstruction of physical phenomena (such as trying to model how a robotic arm needs to accelerate and decelerate in order to reach a particular position in a specified amount of time), because it is the mathematical ideal of force impulse, which is never actually of zero duration, but can often be assumed to be for the sake of simpler calculations.

In the course of writing this, I went to wikipedia once, in order to be able to copy/paste the lower case delta (δ) so that my description would be as accurate as possible. The rest of it is a result of me using it every fucking day for the last six years in the course of getting my Engineering degree and subsequently fucking programming assembly robots.

Blow me, Benito, it's an excuse to paste a webcomic into a thread. I think you're the one who doesn't really know WTF he's talking about. If you really want me to, I'll whip out my signal analysis textbook and cook up an example that uses fourier transforms (do YOU know what those are?), imaginary numbers, AND the fucking dirac delta function if thats what floats your boat and gets you to stop spamming my -1 button.

[edit] So yeah, this was a little over the top. You may now return to your regularly scheduled thread. [/edit]

I...

Well... sorry, I guess I wasn't clear enough.

I meant that maths were serious business, not that you didn't know about them...

And I haven't spammed your -1 button (maybe pressed once? not even sure, I usually leave the karmas alone, seeing how it did drama before). Nor anyone else's... And please, don't try to do an example of all that. I really don't think it'll be anywhere close to clear on the forums.

Edit: To answer your question: No, I don't know what Fourier transforms are... yet. Only Laplace transforms.

e^Pi*sr(-1) to all of you for getting in a maths fight.

And yes this joke is not worth figuring out how to post the actual symbols.

[Luinbariel]

Relax Atom....

pwease?

[KarthXLR]

ummm....QUACK!

karth it's all your fault... -1

[at0m]

take a chill pill brah, because seriously

Point taken. That was a bit of an overreaction. My bad.

This fucking speaks for its fucking self. Fuck humanity.

Fuck humanity.

Yeah... I try not to think like that once in a while.
