• 1. The Expansion of the Universe ; 2. The Cosmic Microwave Radiation Background ; 3. The Early Universe ; 4. Inflation ; 5. General Theory of Cosmological Fluctuations ; 6. Evolution of Cosmological Fluctuations ; 7. Anisotropies in the Microwave Sky ; 8. The Growth of Structure ; 9. Gravitational Lensing ; 10. Fluctuations from Inflation ; Appendices ; A. Some Useful Numbers ; B. Review of General Relativity ; C. Energy Transfer Between Radiation and Electrons ; D. The Ergodic Theorem ; E. Gaussian Distributions ; F. Newtonian Cosmology ; G. Photon Polarization ; H. The Relativistic Boltzmann Equation ; Notation ; Glossary of Symbols ; Assorted Problems

A stimulating source of intellectual excitement. [...] While the relevant technical aspects of the presentation can only be fully appreciated after a careful reading, a clear message emerges with vigour after the first reading: atomic physics, nuclear physics, field theory, high-energy physics and general relativity all come together in the description of our universe. In other words, Cosmology provides a vivid example of the basic unity of physics, which is something to bear in mind during the decades to come.
