This is the summary of two lectures that aim to give an overview of
cosmology. I will not try to be too rigorous in derivations, nor to give a full
historical overview. The idea is to provide a "taste" of cosmology and some of
the interesting topics it covers. The standard cosmological model is presented
and I highlight the successes of cosmology over the past decade or so. Keys to
the development of the standard cosmological model are observations of the
cosmic microwave background and of large-scale structure, which are introduced.
Inflation and dark energy and the outlook for the future are also discussed.
Slides from the lectures are available from the school website:
