Davidson acts as a keen critic to Sagan's works and their vast uncertainties."-Scientific American "A fascinating book about an extraordinary man."-Johnny Carson "Davidson, an award-winning science writer, has written an absorbing portrait of this Pied Piper of planetary science. Davidson thoroughly explores Sagan's science, wrestles with his politics, and plumbs his personal passions with a telling instinct for the revealing underside of a life lived so publicly."-Los Angeles Times Carl Sagan was one of the most celebrated scientists of this century-the handsome and alluring visionary who inspired a generation to look to the heavens and beyond. His life was both an intellectual feast and an emotional rollercoaster. Based on interviews with Sagan's family and friends, including his widow, Ann Druyan; his first wife, acclaimed scientist Lynn Margulis; and his three sons, as well as exclusive access to many personal papers, this highly acclaimed life story offers remarkable insight into one of the most influential, provocative, and beloved figures of our time-a complex, contradictory prophet of the Space Age.

A Life

Carl Sagan

George Smoot

Behold the Handwriting of God Astrophysicist and adventurer George Smoot spent twenty years pursuing the "holy grail of science" -- a relentless hunt that led him from the rain forests of Brazil to the frozen wastes of Antarctica. For decades he persevered -- struggling against time, the elements, the forces of ignorance and bureaucratic insanity. And finally, on April 23, 1992, he made a startling announcement that would usher in a new scientific age. For George Smoot and his dedicated team of Berkeley researchers had proven the unprovable -- uncovering, inarguably and for all time, the secrets of the creation of the Universe.

Todo lo que somos y todo lo que nos rodea proviene de un mismo lugar y un mismo momento: el Big Bang. La cosmología contemporánea, esa disciplina en que la astronomía convive con la física cuántica y la relatividad general para estudiar el origen y la evolución temprana del universo, explica el surgimiento y la distribución de los cuerpos celestes y los elementos químicos. George Smoot y Keay Davidson presentan en este libro un recuento de los hitos que a lo largo del siglo XX transformaron nuestro modo de comprender el cosmos; es además una emocionante bitácora de las aportaciones del propio Smoot —con globos que ascienden a la estratosfera, aviones bombarderos adaptados para la exploración científica, severos viajes a la Antártida, todo ello aderezado con las rivalidades entre distintos grupos de investigación— para escudriñar en el fondo cósmico de microondas, como nunca se había hecho antes, en busca de pequeñas irregularidades —las "arrugas en el tiempo" del título— en la estructura del espacio-tiempo en los primeros momentos del Big Bang. Tal vez la contagiosa pasión que irradia este libro provenga de la certeza de George Smoot de que esos hallazgos fueron "como mirar a Dios" pues logró "vislumbrar el momento mismo de la creación". Por eso Stephen Hawking consideró que éste fue "el descubrimiento científico del siglo, si no es que de todos los tiempos".
