The last book written by Sagan before his death in 1996,[1] it was published by Random House. OverviewThe book is a collection of essays Sagan wrote covering diverse topics such as global warming, the population explosion, extraterrestrial life, morality, and the abortion debate. The last chapter is an account of his struggle with myelodysplasia, the disease which finally took his life in December 1996. Sagan's wife, Ann Druyan, wrote the epilogue of the book after his death. "Billions and billions"To help viewers of Cosmos distinguish between "millions" and "billions", Sagan stressed the "b". Sagan never did, however, say "billions and billions". The public's association of the phrase and Sagan came from a Tonight Show skit. Parodying Sagan's affect, Johnny Carson quipped "billions and billions".[2] The phrase has, however, now become a humorous fictitious number—the Sagan.
