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.
On the pavement a group of schoolchildren was walking past the driveway with their teacher. I noticed these young children crossing and suddenly I saw them in a way I have never seen human beings before or since. They were so full of light I could hardly 1ook, and on each child's chest where the heart is, a huge radiance like the sun was shining. Each little child had this dynamic, brilliant light, this radiant sun, ín the center of their being. The experience of the líght, its brillíance and energy, was beautiful and overwhelming. Later I came to realize that what I saw is the true nature of human beings —we are dynamic, luminous creatures of light.
