Apollonius of Perga Cone

Apolonio of Perga was born in year 262 B.C., in Panfilia (the present Antalya, Turkey), he studied in the Museum of Alexandria with the disciples of Euclides and resided as much in Alexandria as in Epheso and Perga. This last one had a library and a school of wisdom, similars to those of Alexandria, city where he died towards the 190 b.C. Among his many works most well-known is 'the conical ones', the Greek mathematical summit along with 'the elements of Euclides', great treaties of Archimedes , the 'Almagesto' of Ptolomeo, etc. Apolonio demonstrated in his 'Conical' that from a cone can obtain four types of sections, varying inclination of the plane that cuts to the cone; this was a step important in the process to unify the study of the different types curves and this importance revealed almost 2000 years later when Kepler or Newton discovered their fundamental paper in the celestial mechanics. If in many scopes it is necessary to grant to Apolonio the value of pioneer, between all of them is necessary to emphasize his transcendental paper in the coming of the scientific revolution from the Renaissance. Therefore we have that conicals are:

- A circle: a cut with a flat parallel to the base of the cone.

- An ellipse: a oblique section cut with respect to the base.

- A parabola: a cut parallel to a generatrix of the cone that crosses its base.

- A hyperbola: a cut more or less parallel to the hight of the cone, faced its image united by the vertex.
