Paul Davies from the BEYOND Centre for Fundamental Concepts in Science, Arizona State University, will present the Department of Physics Special Colloquium, with a talk entitled, "The software of life".  

Pinning down precisely what makes living matter so distinct is notoriously hard.  Paul proposes that the organisation of information provides a quantitative signature of life and he will present some specific computationsl results that could help define life and elucidate its origin from non-living chemical networks.
