## Do the math!

Hawaii politician thinks she can divide by 0

Ironically, she tells us to “do the math”.

## Math major tip

Thanks to Anderson da Silva for this submission, who has this to add:

I just saw this on the internet and had the urge to come here and share it.
I know Pi is always around but I really never though it would be useful when paying a bill.
Well, what a nice surprise.

P.S. As I said, I saw this on the internet. If you know the source, please feel free to spread the gospel

## Prime Numbers

Several scientists were asked to prove that all odd integers higher than 2 are prime.

*Mathematician: 3 is a prime, 5 is a prime, 7 is a prime, and by induction – every odd integer higher than 2 is a prime.
*Physicist: 3 is a prime, 5 is a prime, 7 is a prime, 9 is an experimental error, 11 is a prime. Just to be sure, try several randomly chosen numbers: 17 is a prime, 23 is a prime…
*Engineer: 3 is a prime, 5 is a prime, 7 is a prime, 9 is an approximation to a prime, 11 is a prime,…
*Programmer (reading the output on the screen): 3 is a prime, 3 is a prime, 3 a is prime, 3 is a prime….
*Biologist: 3 is a prime, 5 is a prime, 7 is a prime, 9 — results have not arrived yet,…
*Psychologist: 3 is a prime, 5 is a prime, 7 is a prime, 9 is a prime but tries to suppress it,…
*Chemist (or Dan Quayle): What’s a prime?
*Politician: “Some numbers are prime.. but the goal is to create a kinder, gentler society where all numbers are prime… ”
*Programmer: “Wait a minute, I think I have an algorithm from Knuth on finding prime numbers… just a little bit longer, I’ve found the last bug… no, that’s not it… ya know, I think there may be a compiler bug here – oh, did you want IEEE-998.0334 rounding or not? – was that in the spec? – hold on, I’ve almost got it – I was up all night working on this program, ya know… now if management would just get me that new workstation that just came out, I’d be done by now… etc., etc. …”

(Two is the oddest prime of all, because it’s the only one that’s even!)
