With clocks, we measure the numerical order of a material change, i.e., motion running in space. There is no experimental evidence that clocks measure time. It is convenient to replace the concept of ...

Before looking at the three-body problem, let's start of with something simpler---the two-body problem. Suppose I have two objects (two stars would work) that are both moving and both interacting with ...
