One of my long-standing interests, as shown by its frequent appearance on this blog, is the idea of information as a constituent of the physical world. I am, of course, particularly interested in the relations which this may have with the concept of recorded and communicable human information.
A valuable new resource for discussing these topics is ‘Information about information’, a section within the Plus mathematics web magazine from Cambridge University.
Supported by the Foundational Questions Institute, this gives ‘popular science level’ accounts of questions such as whether the world is made of information, what is the relation between information and entropy, and whether information can be destroyed in a physical sense.
Well worth following for anyone with an interest in these issues.
