SUMMARY:Fundamental physics with CMB and galaxy surveys\, Theory Semin
 ar (High Energy/Cosmology)\, Moritz Münchmeyer\, Perimeter
DESCRIPTION:Upcoming experiments such as the Simons Observatory\, DESI
  and LSST probe the universe with extremely high resolution. This upco
 ming data provides us with great opportunities for fundamental physics
 \, such as probing the initial conditions of the universe. However\, t
 he vastness and extreme complexity of this interrelated data requires 
 new methods to make sense of it. I will describe two ways forward\, on
 e based on theoretical understanding and one based on computation. In 
 the former\, I show how CMB and galaxy data can be combined in a new w
 ay to give unprecedentedly tight constraints on aspects of primordial 
 physics. In the latter\, I describe a step towards performing precisio
 n cosmology with machine learning\, in a way that builds on the powerf
 ul physical and statistical methodology that has led to the success of
  observational cosmology.
