Conic sections are among the oldest curves, and is one of the oldest mathematics subjects studied rigorously. The conics were discovered by Menaechmus (a Greek, c. 375-325 BC) who was a pupil of Plato and Exodus in an attempt to solve the famous problem duplicating the cube.

Appollonius (c. 262-190 BC) (known as The Great Geometer) consolidated and extended previous results of conics into a monograph Conic Sections, consisting of eight books with 487 propositions.

Appollonius was the first to base the theory of all three conics on sections of one circular cone, right or oblique. He is also the one to give the name ellipse, parabola, and hyperbola. A brief explanation of the naming can be found in Howard Eves, ... Hyperbola, ellipse, and parabola are together known as conic sections,

As it turned out I was teaching about conic sections last week (they arise as traces of quadric surfaces), so I decided I had to show this to my class. I walk to work and didn’t want to carry a lamp in to school, so I decided to make a portable version.
