A system is something that divides the Universe into all that is inside the system as distinct from all that is outside of it. Your body is such a system. So is a tomato can. So is the Earth. Viewed from inside, a system is concave; viewed from outside, it is convex. As the sums of the angles add up, the total is always less degrees than a plane. In order to take a flat piece of paper and make it into any kind of polyhedron, regular or irregular, you are going to have to keep taking out angles to bring it back to itself until, finally, it is a polyhedron. You always come into that concavity and convexity eventually. When energy radiation impinges on concavity, the radiation converges; energy impinging on convexity diverges the radiation. So concave and convex always-and-only coexist. I give you three kinds of always-and-only coexisting functions: tension and compression, concave and convex, and proton and neutron. Now we can develop something we call the theory of functions where we have x and y as the two covariables and have the x standing for tension, convex, and proton and y standing for compression, concave, neutron.
