I’m in this thinking mode because I’m presenting reading “Biological organisation as closure of constraints” in the Journal of Theoretical Biology.
It’s a translation from the original French but the language is kind of standard systems-talk. They talk at a higher level of abstraction, about processes and constraints and degrees of freedom without naming applications most of the time, since they are generally universal within the area of discussion.
biology for example is different from physics. Physics you can have infinite things but biology has “homeostasis”. So this article is delving deeper into the nature of homeostasis, seeing it from another perspective.
