For math geeks
e^j*pi + 1 = 0

That just really rocks. Eat it, those of you who don't dig it.

1. If I'm reading that correctly...
it says that eating pie makes one round?

2. Close
Eating imaginary pie, plus one, leaves you with nothing. A heartbreaking story.

4. Could be so, given that pie are round - not squared!
(Thanks for the setup) :P

3. Shown graphically...

Some of us (yourself included apparently) actually have to use it.

5. OK, that's a damn good graph
Seriously, that makes Euler's identity more apparent and intuitive than anything I've seen before.

6. I was assuming that you were an EE
what with your use of j instead of i to represent the imaginary number. (We EE's use i to represent current.)

7. Indeed
Though I was a math undergrad. I actually got some points in linear circuitry for being able to show Euler's identity from Fourier expansions.

Okay, mathematicians line up here, electrical engineers over there. It's knife-fightin' time!

12. Or, simplified...
e^i*pi = -1

Even beautifuler.

21. I like my way better
Because it uses the three most important operations in mathematics (exponentiation, addition, and multiplication), and the most important predicate (equality), to link the five most important numbers.

22. But if you could strap lasers onto it, it'd be even cooler.
I'll wait for the hybrid version.

13. I'm so glad you used the more proper EE "j" instead of the loser's "i"
:rofl:

EEs fucking ROCK!

19. This reminds me of a story...
A mathematician, a physicist, and an electrical engineer are each trying to determine if all odd numbers greater than 2 are prime.

The mathematician says,
"3 is odd and prime,
5 is odd and prime,
7 is odd and prime,
9 is odd but not prime. Theorem disproved."

The physicist says,
"3 is odd and prime,
5 is odd and prime,
7 is odd and prime,
9 is odd but not prime, but that's probably due to round-off error. We will continue on and see what happens.
11 is odd and prime,
13 is odd and prime,
15 is odd but not prime. Well, it could be some sort of statistical variance so we will continue on and see what happens.
17 is odd and prime,
19 is odd and prime.
Well, of the first nine observations 7 support the theorem so we can say the theorem is probably true."

The electrical engineer says,
"3 is odd and prime,
5 is odd and prime,
7 is odd and prime,
9 is odd and prime,
11 is odd and prime,
13 is odd and prime,
15 is odd and prime..."
