Quefithe
As quoted in Genius: The Life and Science of
Richard Feynman,
by James Gleick, from introduction to Predrag Cvitanović,
Field theory (Nordita, January 1983). The original book is a nearly impossible to get
classic, unless an aging field-theory friend of yours has a copy, but a web version
is available.
Once (and it was not yesterday) there lived a very young mole
and a very young crow who, having heard of the fabulous land called
Quefithe, decided to visit it. Before starting out, they went
to the wise owl and asked what Quefithe was like.
Owl's description of Quefithe was quite confusing. He said
that in Quefithe everything was both up and down. If you knew
where you were, there was no way of knowing where you were going
and conversely, if you knew where you were going, there was no
way of knowing where you were. . . .
Clearly, if they were ever going to learn anything about Quefithe,
they had to see it for themselves. And that is what they did.
After a few years had passed, the mole came back. He said that
Quefithe consisted of lots of tunnels. One entered a hole and
wandered through a maze, tunnels splitting and rejoining, until
one found the next hole and got out. Quefithe sounded like a place
only a mole would like, and nobody wanted to hear more about it.
Not much later the crow landed, flapping its wings and crowing
excitedly. Quefithe was amazing, it said. The most beautiful landscape
with high mountains, perilous passes and deep valleys. The valley
floors were teeming with little moles who were scurrying down
rutted paths. The crow sounded like he had taken too many bubble
baths, and many who heard him shook their heads. The frogs kept
on croaking "It is not rigorous, it is not rigorous!"
. . . But there was something about the crow's enthusiasm that
was infectious.
The most puzzling thing about it all was that the mole's description
of Quefithe sounded nothing like the crow's description. Some
even doubted that the mole and the crow had ever gotten to the
mythical land. Only the fox, who was by nature very curious, kept
running back and forth between the mole and the crow and asking
questions, until he was sure that he understood them both. Nowadays,
anybody can get to Quefithe--even snails.
