ABSTRACT
Mathematics can be a way of travel and a way of survival. Paul Erdos, one of the most prolific mathematicians of all time, died on the twentieth of September 1996. Erdos was the only surviving child of his parents, both Jewish mathematics teachers. He developed an early ability for mathematics and entered the Budapest University at seventeen. So important his network of collaborators became for the development of the twentieth century mathematics that the Erdos number progressed into a project that gained high kudos across the mathematical community worldwide. Erdos was an incredibly generous man, and all his earnings were principally given to various worthy causes. He offered financial prizes for the solutions of unresolved problems in mathematics. With so many papers he wrote and collaborated on, it is pretty obvious that Erdos was interested in a wide range of mathematical fields. He worked in discrete mathematics, graph theory, number theory, mathematical analysis, to name a few.
