**On some applications of the notion of Infinity to the study of Algebraic Curves**: The notion of points at infinity will be used to explain some examples of Diophantus, who found a method of finding rational points on certain Algebraic curves. This notion is used also to explain the definition of the group law on an Elliptic curve.
