By reverse-engineering Newton’s System of the World and its modern extension called “physics”, we see that Newton built a complicated and absurd structure in order to save his assumption of atomic materialism. The assumptions named force, mass, rectilinear inertia, instantaneous action-at-a-distance are all Newton’s inventions to save his atomic materialist assumption.
As soon as we reject Newton’s assumption of atomic materialism, all of his supporting assumptions disappear from physics.
But atomic materialism is the doctrine that claims that entities of finite density are composed of unit entities of infinite density. When we reject this absurd assumption, we realize that the good concept of density is freed from Newtonian ownership and now we can make density, not matter, as the operational unit of nature; this is densytics, physics without Newtonian branding.
