A use for integer quotients

[Skip Montanaro]

    Tim> A mathematician, a physicist, and an engineer were each asked to
    Tim> comment on the assertion "All odd numbers are prime."

    Tim> The mathematician at once gave a counterexample, 9.

    Tim> The physicist said "1 is prime, 3 is prime, 5 is prime, 7 is prime.
    Tim> Now at nine we see second order effects!"

    Tim> The engineer said "1 is prime, 3 is prime, 5 is prime, 7 is prime,
    Tim> 9 is prime..."

I remember that last bit as

    The engineer said "1 is prime, 3 is prime, 5 is prime, 7 is prime.
    Therefore, 'all odd numbers are prime' is true."
