From Nobel Prize–winning physicist P. J. E. Peebles, the story of cosmology from Einstein to today Modern cosmology began a century ago with Albert Einstein's general theory of relativity and his notion of a homogenous, philosophically satisfying cosmos. Cosmology's Century is the story of how generations of scientists built on these thoughts and many new measurements to arrive at a well-tested physical theory of the structure and evolution of our expanding universe. In this landmark book, one of the world's most esteemed theoretical cosmologists offers an unparalleled personal perspective on how the field developed. P. J. E. Peebles was at the forefront of many of the greatest discoveries of the past century, making fundamental contributions to our understanding of the presence of helium and microwave radiation from the hot big bang, the measures of the distribution and motion of ordinary matter, and the new kind of dark matter that allows us to make sense of these results. Taking readers from the field's beginnings, Peebles describes how scientists working in independent directions found themselves converging on a theory of cosmic evolution interesting enough to warrant the rigorous testing it passes so well. He explores the major advances—some inspired by remarkable insights or perhaps just lucky guesses—as well as the wrong turns taken and the roads not explored. He shares recollections from major players in this story and provides a rare, inside look at how science is really done. A monumental work, Cosmology's Century also emphasizes where the present theory is incomplete, suggesting exciting directions for continuing research.

"Can we rely on the discoveries that scientists make about one or another part, or aspect, of the world as a basis for drawing conclusions abou the Universe as a Whole?" Thirty years ago, the separateness of different intellectual disciplines was an unquestioned axiom of intellectual procedure. By the mid-nineteen-seventies, however, even within the natural sciences proper, a shift from narrowly disciplinary preoccupations to more interdisciplinary issues had made it possible to reopen questions about he cosmological significance of the scientific world picture and scarcely possible any longer to rule out all religious cosmology and "unscientific." This book, the product of both a professional and personal quest, follow the debate about cosmology--the theory of the universe--as it has changed from 1945 to 1982. The open essay, "Scientific Mythology" reflects the influence of Stephen Toulmin's postwar study with Ludwig Wittgenstein in its skepticism about the naive extrapolation of scientific concepts into nonscientific contexts. Skepticism gradually gives way to qualified optimism that there may be "still a real chance of working outward from the natural sciences into a larger cosmological realm" in a series of essays on the cosmological speculations of individual scientists, including Arthur Koestler, Jacques Monod, Carl Sagan, and others. In the programmatic concluding essays, Toulmin argues that the classic Newtonian distinction between the observer and the observed was inimical not only to the received religious cosmology but also to any attempt to understand humanity and nature as parts of a single cosmos. In the twentieth century, however, what he calls "the death of the spectator" has forced the postmodern scientist--theoretically, in quantum physics, and practically, in the recognized impact of science-derived technologies on the environment--to include himself in his science.
