Cosmos has 13 heavily illustrated chapters, corresponding to the 13 episodes of the Cosmos television series. In the book, Sagan explores 15 billion years of cosmic evolution and the development of science and civilization. Cosmos traces the origins of knowledge and the scientific method, mixing science and philosophy, and speculates to the future of science. The book also discusses the underlying premises of science by providing biographical anecdotes about many prominent scientists throughout history, placing their contributions into the broader context of the development of modern science. Recommended as a must read book. Cosmos is a thoroughly enthralling read that takes you on a breath-taking journey from the inception of the Universe to futures that may never be, and allows us to ponder--when considering our own epic journey from starstuff to "assemblages of a billion billion billion atoms contemplating the evolution of atoms"--what it truly means to be human and what our place, our purpose, is in the vast expanse of "this Cosmos in which we float like a mote of dust in the morning sky"
