Böcker av P. J. E. Peebles

During the past years, dramatic improvements in methods of observing astrophysical phenomena space have added to our knowledge of the universe. This book presents an overview of physical cosmology, and also discusses the attempts to understand the origin and structure of the universe.

Opinions on the large-scale structure of the early universe range from primeval chaos to a well-ordered mass distribution. This work argues that the evolution proceeded from a nearly uniform initial state to a progressively irregular and clumpy universe. It also describes progress in the use of statistical measures of the clustering.

From the Nobel Prize-winning physicistMan's view of the universe is widening today, as it did once before in the early days of big telescopes and photographic plates. Modern man, by means of radio, infrared, optical, ultraviolet, and X-ray astronomy, can penetrate the universe to depths never before explored. Phillip James Edwin Peebles has written a pioneering work in this newly defined area of investigation. Intended to bridge the chasm between classical textbooks on cosmology and modern developments, Physical Cosmology serves as a guide to current points of debate in a rapidly changing field.Originally published in 1972.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Teaches the often counterintuitive physics of quantum mechanics by working through detailed applications of general ideas. This book uses the hyperfine structure of atomic hydrogen (the 21 cm line): the computation of the energy splitting and the induced and spontaneous transition rates. It emphasizes the art of numerical estimates.
