Mathematical Physics and Life
Abstract
Description
It is a fascinating subject to explore how well we can understand the processes of life on the basis of fundamental laws of physics. It is emphasised that viewing biological processes as manipulation of information extracts their essential features. This information processing can be analysed using well-known methods of computer science. The lowest level of biological information processing, involving DNA and proteins, is the easiest one to link to physical properties. Physical underpinnings of the genetic information that could have led to the universal language of 4 nucleotide bases and 20 amino acids are pointed out. Generalisations of Boolean logic, especially features of quantum dynamics, play a crucial role.
