The length of an ellipse wasn’t discovered until 1914 by Ramanujan. According to Kepler's First Law of Planetary Motion, the orbit of each planet is an ellipse, with one focus of that ellipse at the center of the Sun. Newton's reconsideration of this law states that the orbit of each planet is a conic section, with one focus of that conic section at the center of the Sun. To properly understand planetary orbits, we therefore need some understanding of ellipses in particular and conic sections in general.

Ellipses are used in our everyday lives. It is important to know where they came from and how far they date back (Even though they have been here since the earth was created).

Since you see them everywhere, why not try and learn more about them?
