        Several students were asked to prove that all odd integers are prime.
        The first student to try to do this was a math student.  "Hmmm...
Well, 1 is prime, 3 is prime, 5 is prime, and by induction, we have that all
the odd integers are prime."
        The second student to try was a man of physics who commented, "I'm not
sure of the validity of your proof, but I think I'll try to prove it by
experiment."  He continues, "Well, 1 is prime, 3 is prime, 5 is prime, 7 is
prime, 9 is...  uh, 9 is... uh, 9 is an experimental error, 11 is prime, 13
is prime...  Well, it seems that you're right."
        The third student to try it was the engineering student, who responded,
"Well, to be honest, actually, I'm not sure of your answer either.  Let's
see...  1 is prime, 3 is prime, 5 is prime, 7 is prime, 9 is... uh, 9 is...
well, if you approximate, 9 is prime, 11 is prime, 13 is prime...  Well, it
does seem right."
        Not to be outdone, the computer science student comes along and says
"Well, you two sort've got the right idea, but you'll end up taking too long!
I've just whipped up a program to REALLY go and prove it."  He goes over to
his terminal and runs his program.  Reading the output on the screen he says,
"1 is prime, 1 is prime, 1 is prime, 1 is prime..."
All seems condemned in the long run to approximate a state akin to
Gaussian noise.

Some of the most interesting documents from Sweden's middle ages are the
old county laws (well, we never had counties but it's the nearest equivalent
I can find for "landskap").  These laws were written down sometime in the
13th century, but date back even down into Viking times.  The oldest one is
the Vastgota law which clearly has pagan influences, thinly covered with some
Christian stuff.  In this law, we find a page about "lekare", which is the
Old Norse word for a performing artist, actor/jester/musician etc.  Here is
an approximate translation, where I have written "artist" as equivalent of
"lekare".
        "If an artist is beaten, none shall pay fines for it.  If an artist
        is wounded, one such who goes with hurdie-gurdie or travels with
        fiddle or drum, then the people shall take a wild heifer and bring
        it out on the hillside.  Then they shall shave off all hair from the
        heifer's tail, and grease the tail.  Then the artist shall be given
        newly greased shoes.  Then he shall take hold of the heifer's tail,
        and a man shall strike it with a sharp whip.  If he can hold her, he
        shall have the animal.  If he cannot hold her, he shall endure what
        he received, shame and wounds."
