The One-body Problem,king the limit .. →0. (This involves moving along SR to NRM in Fig. 1.1.)While the text books consider this limiting procedure as straightforward, we will see that some curious features arise when we evaluate the limiting form of the action functional in this context.

The Emergence of Classical Physics,lly understanding it — as we learn more about it! There are several conceptual and technical problems involved in taking the classical limit of a quantum mechanical description. We will not worry too much about the conceptual issues — interesting though they are — but will instead concentrate on one

Orbits of Planets are Circles!,ticated. It turns out that the trajectory of a particle, moving under the attractive inverse square law force, is a circle (or part of a circle) in the . (The high-tech name for the path in velocity space is .). The proof is quite trivial and, in fact, the entire Kepler problem is quite trivial but

Potential surprises in Newtonian Gravity,net—which is distinctly non-spherical in shape—falls exactly as ... outside of it? The initial reaction of many physicists will be: “No, of course, not; you need a spherically symmetric distribution of mass to produce a 1.. force outside it”. Surprisingly, this is not true.
