But even beyond that, mathematical theories have a certain

*tactility*to them. Any equation can be analyzed by applying various algebraic tools, to pick apart its implications. It's a "model" not just in the sense that it represents some phenomena, but also in the sense that you can

*play with it*. It's interactive. Poke it and see what happens. Set this value to zero, apply this identity, distribute these terms... and the theory will react, giving you some response.

This extends similarly to any sort of

*diagrammatic*theory. Free-body diagrams, or circuits, for example. Unique systems of algebra or diagram particularly interest me, though I don't know very many. It's what motivated my spirit graphs concept, I wanted a concise way to "draw" a FNaF theory (And I wasn't satisfied with timelines).

I want more theories to come packaged with unique systems of symbols I can push around, or schematics I can doodle.

*p*and

*u*to

*j*... Let's not worry about this.
