Cosmology (English Edition) Illustrated Editie, Kindle-editie
presents detailed 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.

Klantenrecensies
Klantenrecensies, inclusief sterbeoordelingen voor producten, geven klanten meer informatie over het product en helpen bij de beslissing of dit het juiste product voor hen is.
Om de algehele sterbeoordeling en procentuele uitsplitsing per ster te berekenen, gebruiken we niet een gewoon gemiddelde. Maar ons systeem houdt rekening met zaken als hoe recent een recensie is en of de beoordelaar het item op Amazon heeft gekocht. Het systeem heeft ook recensies geanalyseerd om de betrouwbaarheid te verifiëren.

(1) Weinberg begins with "distance indicators." Read: "the agreement between the values of Hubble Constant provided by these very different methods will serve to validate the cosmological assumptions made in the analysis of cosmic microwave background." (page 31). Before "turning to dynamical theory" we are reminded of the variety of different measures of distance (page 33). Dynamical theory alerts the reader to the importance of General Relativity for the subject. Read: "Lorentz invariance requires that in locally inertial coordinate systems the energy-momentum tensor of the vacuum must be proportional to the Minkowski metric." (page 40). This is your first view of Vacuum Energy.
(2) We remain in chapter one: Expansion of the Universe. Quintessence..."a time-varying vacuum energy" (page 89). Nearly ten pages of exposition where "it may be illuminating to work out the consequences of this one specific model of quintessence." Excellent Pedagogy !
(3) Second Chapter--Cosmic Microwave Radiation Background. This is first brush with the topic, it recurs, time and time again. Grab one of those Modern Physics textbooks and brush-up on "blackbody radiation." (Richtmyer and Kennard). Return to Steven Weinberg for more specialized applications--anisotropies and fluctuations--these will be analyzed. Fourier integrals, Legendre polynomials, Gaussian distributions, all of that and more will be utilized. Conclude with a comparison between experiment and theory.
(4) Before reading chapter three--Early Universe--study Weinberg's 1977 book, The First Three Minutes. Then, return. Now, avail yourself of the fine exposition regards "Cold Dark Matter" (page 185). Read: "if the particles that make up most of the mass of the Universe are not Baryons, what are they ? "Wimps, Supersymmetry and Axions, these things--and more--will occupy the next fifteen pages...as prelude to....
(5) Inflation. Read: "the details of inflation are unknown...it has had one significant experimental success, a prediction of some of the properties of the fluctuations in the cosmic microwave background and large-scale structure." (page 202). Learn of Flatness ("least convincing argument for inflation"), Horizons ("inflation provides an explanation") and Monopoles.
(6) Revisit fluctuations. General relativity (field equations) is front-and-center. Revisit Fourier analysis and "Whatever happens during Inflation, if the Universe subsequently spends sufficient time in a state of local thermal equilibrium with no non-zero conserved quantities, then the perturbations become adiabatic--and, they remain adiabatic subsequently--even when the conditions of thermal equilibrium are no longer satisfied." That statement says a lot ! The ensuing chapter six will provide more details of cosmological fluctuations. Before study of chapter six, a refresher of hydrodynamic, kinetic and Boltzmann equations proves useful.
(7) Next, a tough chapter seven. The chapter revisits the anisotropies in the cosmic background radiation. Read: "The general agreement of theory and observation, both for microwave background anisotropies alone and for background anisotropies in conjunction with other observations, goes far to confirm the general assumptions of the cosmological model, including cold dark matter and dark energy, that we have been using." (page 362). A nice thirty-page exposition on polarization concludes the chapter: "polarization due to scattering by free electrons" which may become more important "in revealing the effects of gravitational waves produced during inflation." (pages 370-400).
(8) Read from chapter nine, Gravitational Lenses: "For cosmology, the most promising application of gravitational lenses probably lies in surveys of weak lensing, the study of distortion of distant galaxies by numerous small deflections of light as it passes from galaxies to us through a slightly inhomogeneous distribution of matter.
(9) The final chapter ten revisits fluctuations. Or, more accurately, inflation as the origin of cosmological fluctuations. Read: "Why should the action of gravitation contain only the Einstein term, and not other generally covariant terms with more than two derivatives of the metric ? And, why should the action of the standard electroweak model or quantum chromodynamics contain only renormalizable terms ? " Learn about it in these pages.
(10) There are appendices: one is survey of general relativity (eighteen pages) and Newtonian cosmology. Another (appendix H) outlines material needed for understanding of Boltzmann equation (as prelude to chapter six and seven). The Cosmology text of Weinberg was my latest serious look into cosmology.
No matter what the future holds, because Weinberg presents experimental numbers alongside theoretical models, his book remains invaluable. Without such interplay between experiment and theory, I am hard-pressed to call the subject physics.
