These talks will be self-contained presentations of mathematical concepts and theorems. They are intended to be accessible to all mathematics
students.  Coffee, tea and drinks will be provided.

The topic of Life in the Universe is a fascinating one, and until recently we have had virtually no way of answering, or in many cases even posing, the relevant questions. In this lecture I will review those questions, the best answers we have, and discuss the areas where we know very little. This is a rapidly growing field and much has happened in the last few years which changes dramatically our view of Life in the Universe.
