Paul Erdos is famous in the world of mathematics. He spent his life travelling America, finding mathematicians to befriend and helping them with their work.
In order to honour his contributions, the “Erdos Number” was created. Anyone who collaborated with Erdos on a paper has an Erdos Number of 1, any of their collaborators have an Erdos Number of 2, and so on.
511 people can claim an Erdos Number of 1. 8,763 people have of 1 or 2. The numbers get bigger…
