# UST Cosmology lecture series

### Course Overview

Lecturer: David Parkinson

This course will give an overview of the physics of the universe as a whole. It will start with a brief derivation of the FRW metric, and how it responds to the presence of matter and energy. It will go through the form of the expansion of the Universe, and the propagation of light and matter through it. It will also cover the physics of the early universe, the creation of the chemical elements during primordial nucleosynthesis, and the accelerated expansion during the period of cosmological inflation. It will end with a derivation of the formation of structure, and the creation of the relic radiation of the Big Bang, the Cosmic Microwave Background.
