In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century? Here, too, is a rare, private glimpse of Sagan's thoughts about love, death, and God as he struggled with fatal disease. Ever forward-looking and vibrant with the sparkle of his unquenchable curiosity, Billions & Billions is a testament to one of the great scientific minds of our day.

From Library Journal

It is doubtful that there is anyone unfamiliar with noted astronomer and science writer Sagan's ability to convey the wonder, excitement, and joy of science. This book is a wonderful, if eclectic, collection of essays, some reprinted from magazines of national prominence, covering a wide range of topics: the invention of chess, life on Mars, global warming, abortion, international affairs, the nature of government, and the meaning of morality. Writing with clarity and an understanding of human nature, Sagan offers hope for humanity's future as he illuminates our ability to understand ourselves and to change the world for the better. The last chapter is an account of his struggle with myelodysplasia, the illness that finally took his life in December 1996. An epilog written by his wife is a personal account of the man rather than the scientist admired by so many. This last book is a fitting capstone to a distinguished career. Enthusiastically recommended.

From Booklist

Carl Sagan died last December, and as a result, these essays exude a feeling of interrupted eloquence. The celebrity planetary astronomer possibly had more books to write that could have compared favorably with his Cosmos (1980) or Pale Blue Dot (1994), but disappointingly, this collection does not bloom like those dependable library perennials. Perhaps expectations are overly inflated with a new Sagan exposition in hand--but here, expectations rapidly deflate upon seeing that the contents comprise much reprinted material, such as nonscience articles he and his wife and coauthor, Ann Druyan, wrote for a Sunday newspaper supplement. One Parade piece, advancing their argument in favor of legal abortion, sourly criticizes televangelist Pat Robertson for using his influence to mobilize opposition to the 1990 article, a point that skates over the sway the authors themselves were trying to exert in the abortion controversy by means of their article. In other chapters, the subjects are flat--an explanation of the origin of Sagan's brand-name cliche"billions and billions" --or the subjects are rudimentary. Blemishes apart, this collection offers some worthwhile essays: his account of battling cancer or summaries of the enviro-political issues that he weighed in on, such as ozone depletion and the fossil fuels^-atmospheric warming nexus. However uneven and eclectic, this tome still flashes with Sagan's curiosity, wonder, and humanity concerning the scientific enterprise. Gilbert Taylor
