The Atacama Cosmology Telescope has recently reported the most accurate measurements of temperature and polarization of the cosmic microwave background. I will highlight these results and their implications for our understanding of cosmology. The new measurements constrain the number and mass of neutrinos, the presence of new light particles, the properties of dark matter and dark energy, and the physics of inflation. .
