How to tell you ticked off a mathematician
MonMotha:
Except that e^(j*pi) = -1. Look up Eueler's identity/Euler's formula.
(yes, j, not i...real engineers know that i is time-domain current!)
The summation is correct. It does work out to 1.
Therefore, this check is made out for 0.002 - 1 + 1 = 0.002. I presume this is in reference to the "0.002 cents per kilobyte" fiasco.
Just my 0.002 cents...
Oh, and FWIW, engineering does frequently use the e^(j*stuff) thing as it is a common way to represent complex numbers in "polar" format. The EEs use this all the time, but they'd use j, not i, so I have no idea what's up with that check. The other engineering disciplines (that would be more apt to use i for sqrt(-1)) tend to have less use for that sort of thing.
hypernova:
Been ten years since calculus in high school. Aced the final exam.
College peer asked if I could look over her homework from algebra 102. 102, I thought. What a cakewalk. A joke.
It dealt with imaginary numbers. Even looking at the process, nothing clicked.
Oh well. I can still get the derivative of simple, single variable formulas or equations or whatever they're called, like 4x^4, or x^6. The single coefficient (hey, I remember that term) and the power it's being raised is all I can do now. (16x^3, and 6x^5 are the answers. At least I hope so.) :)

Yeah, but do you remember what the deriviative means? ;)
Ed_McCarron:
Two things.
One, never combine alcohol and calculus. Never drink and derive.
Two, did you hear the one about the constipated mathematician? He worked it out with a pencil.

Incidentally, has anyone here noticed that, in the original Terminator film, the view of the world as seen through the Terminator's eyes shows a scrolling list of 6502 assembler code! So the Terminator's brain appears to be powered by a 2 MHz processor!
If noticing that isn't enough to demonstrate my geek credentials then I don't know what is.

I just watched this the other night and was thinking about that. Of course most people wouldn't know that. And unless they were just showing the stuff to illustrate it's internal function, I think (and have for years thought) it was silly anthropomorphism.

I like to think of it as being socially deficient...

No no. That's just a part of the 'wave function'.
