The sea's only gifts are harsh blows and, occasionally, the chance to feel strong.

He was a physicist, more precisely an astrophysicist, diligent and eager but without illusions: the Truth lay beyond, inaccessible to our telescopes, accessible to the initiates. This was a long road which he was traveling with effort, wonderment, and profound joy. Physics was prose: elegant gymnastics for the mind, mirror of Creation, the key to man's dominion over the planet; but what is the stature of Creation, of man and the planet?
