The main points are highlighted in italics throughout. We are beginning to learn the answers to some fundamental questions, using information contained in CMB anisotropy data. With future experiments, and the MAP and Planck satellites in particular, we should expect to learn vastly more in the coming years about astrophysics, cosmology and particle physics.
I would like to thank my collaborators, and in particular members of the Planck team. Since this is a conference proceedings report, I have shamelessly concentrated on my own work - see the original papers for more comprehensive references. I am also grateful to the members of CITA for their hospitality during the writing of this article.
