So our problem is to explain where symmetry comes from. Why is nature so nearly symmetrical? No one has any idea why. The only thing we might suggest is something like this: There is a gate in
Japan, a gate in Neiko, which is sometimes called by the Japanese
the most beautiful gate in all Japan; it was built in a time when
there was great influence from Chinese art. This gate is very elaborate,
with lots of gables and beautiful carving and lots of columns
and dragon heads and princes carved into the pillars, and so on.
But when one looks closely he sees that in the elaborate and complex
design along one of the pillars, one of the small design elements
is carved upside down; otherwise the thing is completely
symmetrical. If one asks why this is, the story is that it was carved
upside down so that the gods will not be jealous of the perfection
of man. So they purposely put an error in there, so that the gods
would not be jealous and get angry with human beings.
We might like to turn the idea around and think that the true
explanation of the near symmetry of nature is this: that God made
the laws only nearly symmetrical so that we should not be jealous
of His perfection!

If we are to replace standard numerical probability usage with engineering judgment, why do we find such an enormous disparity between the management estimate and the judgment of the engineers? It would appear that, for whatever purpose, be it for internal or external consumption, the management of NASA exaggerates the reliability of its product, to the point of fantasy.

The electron is a theory we use; it is so useful in understanding the way nature works that we can almost call it real.
