### "Bayesian networks, information and entropy"

## Abstract

Nature and the world of human technology are full of

networks. People like to draw diagrams of networks: flow charts,

electrical circuit diagrams, signal flow diagrams, Bayesian networks,

Feynman diagrams and the like. Mathematically-minded people know that

in principle these diagrams fit into a common framework: category

theory. But we are still far from a unified theory of networks.
