Paul Erdős

Paul Erdős was a Hungarian mathematician who made significant contributions to number theory and discrete mathematics. He is best known for his work on prime numbers, combinatorics, and graph theory, among other areas. Erdős had a unique lifestyle, frequently collaborating with other mathematicians and traveling the world, which led to the concept of the "Erdős number" – a way to describe the collaborative distance between mathematicians based on their joint publications. His work has had a lasting impact on mathematics, influencing various fields through his innovative ideas and profound problems that still challenge mathematicians today.
