An engineer, a physicist, and a mathematician are shown a pasture
with a herd of sheep, and told to put them inside the smallest
possible amount of fence. The engineer is first. He herds the sheep
into a circle and then puts the fence around them, declaring, "A
circle will use the least fence for a given area, so this is the
best solution." The physicist is next. She creates a circular fence of
infinite radius around the sheep, and then draws the fence tight around
the herd, declaring, "This will give the smallest circular fence around
the herd." The mathematician is last. After giving the problem a little
thought, he puts a small fence around himself and then declares, "I
define myself to be on the outside!"
