The late great astronomer and astrophysicist describes his personal search to understand the nature of the sacred in the vastness of the cosmos.

World renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are.

Moneyball reveals a quest for something as elusive as the Holy Grail, something that money apparently can't buy: the secret of success in baseball. The logical places to look would be the giant offices of major league teams and the dugouts.
