In this book, his last, Carl Sagan shows once again his extraordinary ability to interpret the mysteries of life and the majesty of the universe for the general reader. Brilliant, eloquent, and imbued with Sagan's uniquely childlike sense of awe, this entertaining collection of essays captures the authors spirit at its best.
In Billions and Billions Sagan applies what we know about science, mathematics, and space to everyday life, as well as to the exploration of many essential questions concerning the environment and our future. Ranging far and wide in subject matter, he takes his readers on a soaring journey, from the invention of chess to the possibility of life on Mars, from Monday Night Football to the relationship between the United States and Russia, from global warming to the abortion debate. And, on a more intimate note, we are given a rare glimpse of the author himself as he movingly describes his valiant fight for his life, his love of his family, and his personal beliefs about death and God.
Throughout these essays, Sagan provides clarity and understanding for an audience eager to make sense of the world around it as it prepares for the challenges of the coming millennium, and in the process he illuminates his strongly held belief that we have the ability to change the world and our lives for the better.
Sagan has said, We make our world significant by the courage of our questions and by the depth of our answers. With this book, as in his magnificent career, he makes this world significant indeed.
We based our evaluation of book condition on the following criteria:
* New: Just like it sounds. A brand-new, unused, unread copy in perfect condition.
* Like New: An apparently unread copy in perfect condition. Dust cover is intact; pages are clean and are not marred by notes or folds of any kind.
* Very Good: A copy that has been read, but remains in excellent condition. Pages are intact and are not marred by notes or highlighting, but may contain a neat previous owner name. The spine remains undamaged.
* Good: A copy that has been read, but remains in clean condition. All pages are intact, and the cover is intact. The spine may show signs of wear. Pages can include limited notes and highlighting, and the copy can include "From the library of" labels or previous owner inscriptions.
* Acceptable: A readable copy. All pages are intact, and the cover is intact (the dust cover may be missing). Pages can include considerable notes--in pen or highlighter--but the notes cannot obscure the text.
