Re: Kepler ,Newton and orbital geometry

Rather than go through the details,and they are intricate,perhaps it
is best to demonstrate why it is neccessary to revisit the explanation
for Keplerian orbital geometries and how the late 17th century
shortcuts creates multiple problems elsewhere such as the pressing
need to modify the cause for the seasons by concentrating on the
orbital motion of the Earth and Keplerian orbital geometry.

Newton did not take shortcuts, and except for failing to come up with
the Special and General Theory of Relativity, nothing is lacking in
Newtonian mechanics.

The truth of Newton's mechanics, of the inverse-square law of
gravitation, of the conservation of angular momentum, is reaffirmed
countless times in the workings of our machines, and especially in the
paths of automated space probes launched to photograph the planets of
our solar systems.

If Newton were wrong, the Apollo astronauts would not have made it
back home.
