Both the ellipse and the hyperbola are geometric places that can be defined by establishing a relationship between points $P$ of the plane and two fixed points $A$ and $B$ (which are its foci $F'=A$ and $F=B$). Given two points $A$ and $B$ of the plan (which we no longer call the foci $F$ and $F'$), we are going to present three geometric places associated with $A$ and $B$ other than the ellipse and the hyperbola.
In this article, we present a description of the \textit{apparatus} employed by Henry Cavendish, which in turn is actually a compendium of 17 complex experiments, to try to experimentally measure the universal gravitation constant, theoretically posed by the divine Sir Isaac Newton, in his monumental \textit{Principia Mathematica}.\\ Since the gravitational force is very small, gravitational experiments in the laboratory are highly susceptible to strange disturbances. Measuring gravitation in the laboratory is then that problematic and today such difficulties persist.
A brief review of the history of the conic sections would not be complete without an exhaustively tolerable account of all the things related to the subject that can be found in the extensive work of the wise Archimedes. There is no strong evidence that the Syracusan genius wrote a treatise on Conics separately.
