Programming with Categories

Brendan Fong, Bartosz Milewski, and David Spivak, have just kicked off a new course at MIT called Programming with Categories. I don't live in Boston so I can't attend the course, but I am watching the videos as they come out. In lecture 2 (about time 5:30), Brendan introduces the informal concept of Shape.

I very much like this idea of shapes, where each Shape suggests "the essence of" a basic idea in Category Theory. To me this provides a way to informally use these concepts. I can take this essence and use it in any way that provides some practical value.

This is roughly the table that Brendan presented.

Universe of Fish

In the Cybernetics Bookclub, we have discussed the concept of closed and open systems, and how these two types of systems differ from each other. JP has approached it from the perspective of the mathematical equations presented by Bertalanffy. Jen and I use Agent-Based Modeling (ABM), and are more comfortable thinking of closed and open systems from an ABM perspective.

ABM, also called Individual-Based Modeling (IBM), focuses on the interactions between individuals. The math approach, using Ordinary Differential Equations (ODE), focuses on the changing values of variables. Change over time is important in both approaches.
