Notice that Feynman's large circle or velocity circle, which contains the ellipse, is centred on the Sun. I don't use a velocity circle but I do use a large circle which appears to be the same thing as the velocity circle. However, the centre of my large circle is located at the empty focus (Fe). I see gravitational motion as a dance of circles rather than as a force acting on inertial motion. In my opinion the law of inertia should only apply to motions which are clearly caused by collisions or forces of contact. In this respect I am granting circles a power they have not had since before Newton. Harry
