Thanks, Sean, we needed that! :) (03)
There is also the old joke about distinguishing mathematicians,
scientists and engineers: Ask them to consider the theory that all odd
numbers are prime. The mathematician considers, 1 is "prime", 3 is
prime, 5 is prime, 7 is prime, 9 is not prime; the theorem is false.
The scientist considers, 1 is prime, 3 is prime, 5 is prime, 7 is prime,
9 is not prime, 11 is prime, 13 is prime; the theory may be valid, but
there is unexplained experimental deviation. The engineer considers,
1 is prime, 3 is prime, 5 is prime, 7 is prime, 9 is prime, 11 is prime ... (04)
