We now have a well established standard model of cosmology that agrees with virtually all cosmological observations regardless of the method or the object under study. The model is based on physics of the Universe at 10^{-35} sec, and makes testable predictions directly linked to physics of that epoch. The Planck satellite, now in orbit, will deliver multifrequency full-sky maps of mm-wave sky of unprecedented precision. Among other things, these maps can be use to test, and if necessary modify, the standard model. In this talk, we review the foundations of the standard model with an emphasis on what we can learn from ground-based measurements of the temperature and polarization of the CMB that complement Planck. The focus will be on the scalar spectral index, gravitational waves, and the sum of neutrino masses.
