- Well, there was an even longer version running around a while ago. Here
- it is:
- A roomful of professionals are all asked to prove that all odd numbers
- (besides 1) are prime.
-
- The physicist says: "3 is prime... 5 is prime... 7 is prime... 9... well,
- experimental error. 11 is prime... ..."
-
- The mathematician says: "3 is prime, 5 is prime, 7 is prime... therefore,
- by induction on 2n-1, all odd numbers are prime."
-
- The engineer says: "3 is prime... 5 is prime... 7 is prime... 9 is
- prime... 11 is prime... ..."
-
- The chemist says: "3 is prime, 5 is prime, 7 is prime; well, I guess
- that's enough data!"
-
- The Biologist says: "What's a prime?"
-
- The programmer says: "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 tha just came out, I'd be done by now... etc., etc. ..."
-
- The computer scientist says: "3 is prime... 5 is prime... 7 is prime... 7
- is prime... 7 is prime... 7 is prime... ..."
-
- The psychologist says: "3 is prime... 5 is prime... 7 is prime... 9 is
- latently prime but repressing it... 11 is prime... ..."
-
- The social scientist says: "3 is prime... 5 is prime... 7 is prime...
- we'll pretend 9 is prime... 11 is prime... ..."
-
- The sociologist says: Proof by a sociologist: "2 true, 4 true, 6 true, 8
- true, ..."
