analytic calculations of cosmological phenomena, rather than just report results obtained elsewhere by numerical computation. The book is up to date, and gives detailed accounts of topics such as recombination, microwave background polarization, leptogenesis, gravitational lensing, structure

formation, and multifield inflation, that are usually treated superficially if at all in treatises on cosmology. Copious references to current research literature are supplied. Appendices include a brief introduction to general relativity, and a detailed derivation of the Boltzmann equation for photons and neutrinos used in calculations of cosmological evolution. Also provided is an assortment of problems. - ;A tour de force that even establishes cosmologists will learn from. Any scientist interested in cosmology should read it. - ;Steven Weinberg's "Cosmology" is a thorough, graduate-level introduction to the field, which incorporates the frenzied developments since his 1972 classic, "Gravitation and Cosmology". This is sure to be another hit. -  less
