My math background, particularly use of proper math terminology, is somewhat
elementary at times. Recently, I have taken several refresher courses in
calculus. It's been an interesting experience.
I was not familiar with the term "Laplace–Runge–Lenz vectors". I may have
shorthanded the term,
Yes! ^_^'"

I assume you miss keyed "R" as "G".

What does "LGL" stand for?

I have other projects! But if I have to suggest anything is to try to find
Kepler's law using LGL vectors in the simplest way.

Woah! I didn't expect to see so much commentary on this particular thread. I
had to re-subscribe a while longer.
Harry, the link you supplied on Feynman's Lost Lecture on Motions around the
Sun did the trick for me. I finally get what your animated GIF was trying to
tell me. I like what
I'm sorry, orbits. You could try to find the law using it.
There is also the LRL vector, which can be used to derive Kepler's law in 3
lines:

Yes, it is possible to begin with kepler's laws and the law of inertia and
derive the force law of gravity or to begin with the force law of gravity
and the law of inertia and derive Kepler's laws.
I am working on third way.

Hmm! Gary also derived using the original method, so it is good to see both
approaches and how algebra makes life so much easier than just using
geometric algebra. In Newton's time, though, geometric algebra was widely
teach, more so than algebra, including theorems about ellipsis which are
not as
Newton's derivation of the force of gravity from Kepler's law of ellipsis
is explained nicely in this series of lectures:

Steven,
I know that in the past you have wondered if the second focus of an ellipse
could have any role to play in the determination of orbits, since it plays
no role in Kepler laws or in Newton's derivation of Kepler laws. Well a
few years ago, I invented a geometrical method in which the
I've been retired now for almost 18 months. I'm happy to report I'm not
bored. My on-going Kepler research project continues to consume much of my
quality time. But alas, summer is just around the corner, and there seems to
be a spate of honey-do projects that are about to consume a good chunk of
19 matches
