Book cover designed for Cosmos by Carl Sagan.
'Exploring 15 billion years of cosmic evolution and the development of science and civilization, Cosmos traces the origins of knowledge and scientific method, mixing science and philosophy, and speculates as to the future of science. It also discusses the underlying premise of science by providing biographical anecdotes about prominent scientists throughout history, placing their contributions into the broader context of the development of modern science. Cornell News Service characterized the book as "an overview of how science and civilization grew up together." Covering a broad range of topics, Sagan reflects on anthropological, cosmological, biological, historical, and astronomical matters from antiquity to contemporary times.' The overall design mimics the light, conversational tone used by Sagan to render complex scientific topics readable for a lay audience.
