Fundamental symmetries and their violations play a particular role in our understanding of nature. In the lecture we will start by out-lining some of the concepts in relation to molecular physics [1,2,3] in a very down to earth way, and then consider the consequences for and relationships to biology, physics and cosmology in a somewhat less down to earth perspective.
