“Why Standard Economic Models Don’t Work–Our Economy is a Network”

]]>Did you cross Gail Tverberg essays about networked economy?

In this post (and others) she writes about Increased complexity in our societies (and their impeding collapse?)

Merci pour votre effort de vulgarisation!

But he went further: to understand the *externally observable behavior* of an open system we often want to simplify a decorated cospan and get another sort of structure, which he calls a ‘decorated corelation’. His talk here explains decorated corelations and what they’re good for:

• Wikipedia, Tonti diagram.

• Algebraic formulation of physical fields.

I’m not ready to say anything about this work.

]]>The talk also left me wondering about ways in which the challenge of applying denotational semantics / category theory to understanding physical systems from their pieces, might be different from doing this with programs (Prakash seemed unconcerned with the continuous/discrete distinction, which naively seems important).
