So, the phrase relies on this idea of the theory of the perfect wheel, or simply, the form of the wheel. All of the other changes are superficial. There is no single perfect wheel as it is designed based on technology limitations and load and environmental factors. While the load bearing surface has always been a characteristic of rotating machines, bearings are a missing component of the design for centuries. I would argue that bearings are the true form of the perfect wheel and that they are more generalized function, and being in the world of forms, rely heavily upon the world of forms. This is the case as bearings are have many different geometries for the rolling elements, or even sliding designs. They say reinvent the wheel and I am trying to figure out what caveman figured out how to roll steel pellets into balls.
