A Strange and Hidden Relationship

 

“In mathematics, the parabola is a conic section, the intersection of a right circular conical surface and a plane to a generating straight line of that surface. Given a point (the focus) and a corresponding line (the directrix) on the plane, the locus of points in that plane that are equidistant from them is a parabola. The parabola has many important applications, from automobile headlight reflectors to the design of ballistic missiles.”
