## Warning: Nerd Joke

### January 31, 2007

My Discrete professor told a joke today that I thought was worth sharing. So without further ado:

*One day, a computer scientist, an engineer, a physicist, and a mathematician were brought together in a conference room. They were given the task of proving that all odd numbers are prime.*

*The computer scientist started, “Zero, one. Hm, both of them are prime. Therefore all odd numbers are prime!”*

*The engineer began to count, “One, three, five, seven, nine, eleven, thirteen… yep, all primes so far. Therefore, all odd numbers are prime.”*

*The physicist, catching onto the engineer’s error, counted, “One, three, five, seven, nine, eleven… well, one, three, five, seven, and eleven are all prime. The nine must be due to experimental error! Therefore, all odd numbers are prime.”*

*The mathematician simply left the room, shaking his head.*

I know, I know. One isn’t a prime number. And zero isn’t technically even or odd. But we had to put them in there to make the joke.

:)

I’m disappointed. I think that the one with the guys and the girls dancing in the room is better. Tell me that you’ve heard it?

Well anyway, its guys on one side, girls on the other, and every time the music stops, or whatever… something happens… they walk halfway towards the center of the room. Then halfway again, then again, then again… so if you remember zeno’s paradox, the limit of sum(1/2^t) = 1

The question is, how many times do they have to “walk the distance” to reach eachother.

The observers include a mathematician, a scientist, and an engineer.

The mathematician says infinity, the scientist says never, and the engineer says after a few, they’ll be close enough for all practical purposes.

Yeah. For some reason that wasn’t that funny to me.

Now Davem’s joke is much better. Engineers are cool like that.

The prime number joke was okay especially in the context of my own history with “experiemental error.”
