Ebook: Billions & Billions: Thoughts on Life and Death at the Brink of the Millennium

An amazing book by an amazing man. Carl Sagan is one of my heroes who has shown me how breathtaking the universe is. In this book, Sagan speaks very personally about matters deep to him, issues he was engaged in during his life. He presents arguments like the Prisoner's Dilemma and his solution to the arms race.
The book ends with him talking about his last round of cancer therapy, and is then completed by his wonderful wife Ann Druyan. Though Carl is no longer with us, his memory lives on in the minds of billions of earthlings now and I hope all future generations will appreciate this great man as I do.
