Science has explored the microcosmos and the macrocosmos; we have a good sense of the lay of the land. The great unexplored frontier is complexity.

Stars are like animals in the wild. We may see the very young but never their actual birth, which is a veiled and secret event.

Science is expanding, and with it our vision of the universe. although this new and constantly changing view may not always give us comfort, it does have the virtue of truth according to our most effective resources for acquiring knowledge. No philosophy, moral outlook, or religion can be inconsistent with the findings of science and hope to endure among educated people.

The words are strung together, with their own special grammar-the laws of quantum theory-to form sentences, which are molecules. Soon we have books, entire libraries, made out of molecular "sentences." The universe is like a library in which the words are atoms. Just look at what has been written with these hundred words! Our own bodies are books in that library, specified by the organization of molecules-but the universe and literature are organizations of identical, interchangeable objects; they are information systems.

Possession of a program with unique analytic capabilities puts a scientist in as much of a priveleged position to make new discoveries as the possession of a powerful telescope.

The world changed from having the determinism of a clock to having the contingency of a pinball machine.

Theoretical and experimental physicists are now studying nothing at all-the vacuum. But that nothingness contains all of being.
