Fractals + 2nd Order Logic?
Barely knowing what I’m thinking about, I thought “There should be a connection between second order logic and fractals because of its ability to be recursive (by including itself in its own definition (or ranging over sets if you like))) and a quick search and it’s true:
I can’t READ anything beyond the first Intro (and that, barely. But I know what a sierpinski carpet is and just enough of what makes second order logic differ from first order logic to embrace it as suitable for my thinking)
