Cosmology Lectures by Sean Carroll

A set of five excellent lectures on cosmology given by Sean Carroll at CERN in 2005. Though these lectures are not for the amateurs in cosmology, one can develop appreciation for the theory behind widely popular terms like inflation, dark matter and dark energy.

Here are the youtube links to the lectures
