I read this short but very meaningful article, and I remembered a comment of mine from times past. I was brought up with electronics symbols. Eventually, after learning how they are physically constructed, it became apparent to me why, for instance, a resistor was a zigzag line and an inductor was a springy-looking thing. When I encountered some other physical mathematics, some of the symbols used were of a spring, a weight on a string, a brush or something that represented friction (I was never quite clear what it was supposed to be) etc, but the ones I was most familiar with, because of their usefulness, were the electronics symbols.
It strikes me that there is no such symbology for diagramming the workings of the human body. I don't know if there is such a set of symbols for terms in hydrodynamics, but it seems to me they, and probably a lot more, would come in handy. I took this paper and reduced it to a set of unique terms, at least some of which could be featured in a diagram illustrating this paper, and some of which could be shown as standard symbols, marked with scientific units of quantity or describing somehow their physical properties quantitatively. Some things could be shown with more generic symbols, such as a large arrow, for instance, to indicate "bulk flow". Others could be more pictorial. Then more people, I think, could be "on the same page".
Please excuse this list as it is meant only to be an example and not to be rigorous or exact or complete in any way.
It would be nice if there were well-understood symbol rules too, like: Greek symbols for fluid properties, etc.
