Each morning we awaken to the light and the invitation to a new day in the world of time; each night we surrender to the dark to be taken to play in the world of dreams where time is no more. At birth we were awakened and emerged to become visible in the world. At death we will surrender again to the dark to become invisible. Awakening and surrender: they frame each day and each life; between them the journey where anything can happen, the beauty and the frailty.
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.
