UoB Benjamin Meaker Visiting Professor Benjamin Schumacher (Kenyon College, Ohio) will give a public lecture entitled: Axiomatic Information Thermodynamics

The basic concepts of thermodynamics have been probed in many ways.  Mathematicians have built systems of axioms to illuminate their essential logical structure.  Contemporary physicists, inspired by Maxwell's famous "demon", have come to regard information as the most fundamental idea in the theory.  In this lecture we will bridge the gap by exploring axioms that incorporate information in a fundamental way.  Thermodynamics deals with how the states of physical systems may be changed by agents that are themselves physical.  They may acquire, use and erase information; but what is information?  From simple axioms about such agents, we will see the emergence of conservation laws, reversible and irreversible processes, thermodynamic and information entropy, Landauer's principle about the thermodynamic cost of computation, and even the concept of probability.

The lecture is open to all, and will be followed by a drinks reception.
