Prime numbers
Once upon a time, when I was training to be a mathematician, a group of
us bright young students taking number theory discovered the names of the
smaller prime numbers.
2: The Odd Prime --
It's the only even prime, therefore is odd. QED.
3: The True Prime --
Lewis Carroll: "If I tell you 3 times, it's true."
31: The Arbitrary Prime --
Determined by unanimous unvote. We needed an arbitrary prime in
case the prof asked for one, and so had an election. 91 received
the most votes (well, it *looks* prime) and 3+4i the next most.
However, 31 was the only candidate to receive none at all.
41: The Female Prime --
The polynomial X**2 - X + 41 is
prime for integer values from 1 to 40.
43: The Male Prime - they form a prime pair.
Since the composite numbers are formed from primes, their qualities
are derived from those primes. So, for instance, the number 6 is "odd
but true", while the powers of 2 are all extremely odd numbers.
