The purpose of this course is to provide a comprehensive introduction to cosmology - a science that has the `modest' aim of understanding the Universe as a whole as well as its parts. We will cover the basic material needed to understand recent observational and theoretical developments. The course is organised in two parts: Part I introduces the relevant pieces of physics and astronomy and Part II presents applications of the latter to more recent research results. The selection of topics will broadly follow John Peacock's book Cosmological Physics. Special talks on advanced topics will be given by local as well as external speakers.

Lectures will be held weekly on Wednesdays at 11.00 am in the T-Division conference room (Room 121, Bldng. 123, TA-3). The co-organizers are Katrin Heitmann and Luis Teodoro.

We would like to thank Salman Habib for supporting and helping us organizing this course and also for giving many excellent lectures. We also want to thank the other speakers, Asa Hopkins, Gerard Jungman, and John Terning. Without their help it would have been impossible to have this course.
