We review the theory of the temperature anisotropy and polar ization of the cosmic microwave background (CMB) radiation, and describe what we have learned from current CMB observations. In particular, we discuss how the CMB is being used to provide precise measurements of the composition and geometry of the observable universe, and to constrain the physics of the early universe. We also briefly review the physics of the small-sca e CMB fluctuations generated during and after the epoch of… CONTINUE READING
