...don't worry about what is reality,
or what is plain, or what is mysterious.
If you were there, it was all those things.
If you can imagine it, it is all those things.
Eat, drink, be happy.
Accept the miracle.
Accept, too, each spoken word
spoken with love.
~ from "Logos" by Mary Oliver, in WHY I WAKE EARLY
Perhaps it seems surprising that physicists seek beauty, but in fact they have no choice. As yet there has not been an exception to the rule that the demonstrable solution to any problem will turn out to be an aesthetic solution.
