SUMMARY:Measuring the CMB Polarization with the Atacama Cosmology Telescope
 .
DESCRIPTION:Measuring the CMB Polarization with the Atacama Cosmology Teles
 cope.\nProf. Lyman Page\n\nWe have learned a great deal about the universe
  from measurements ofthe  cosmic microwave background (CMB). Most of what 
 we have learned so far  has been based on the temperature anisotropy combi
 ned with measurements  of the polarization at angular scales of roughly 10
  degrees. We are  entering a new era in which the polarization of the CMB 
 will be measured  to high accuracy especially at degree angular scales and
  smaller. With  the polarization we can, for example,  measure or lim
 it the presence of  gravitational radiation from the early universe and de
 termine the sum of  the neutrino masses. The polarization will also give u
 s a new way to  determine the cosmological parameters. We review recent re
 sults on the  CMB polarization with anemphasis on those from the Atacama C
 osmology  Telescope (ACT) project.
