Postscript: Ellipses are common in physics, astronomy, and engineering. For example, the orbits of each planet in our solar system are approximately elliptical, with the planet and the sun's focus being the center of gravity at one focus. This is also true for satellite orbits and all other systems with two celestial bodies. The shapes of planets and stars are typically described by ellipsoids. Ellipses also appear in circular images under parallel projections and in the bounded shells of projections, which are simple intersections of the projection cone with the projection plane. When horizontal and vertical movements are sine waves of the same frequency, they also form simple Lissajous figures. Similar effects lead to the elliptical polarization of light in optics.
