Paul Erdos remains one of the most revered mathematicians in history. His name sits right alongside Newton in the golden halls of academia. Erdos was eccentric, foregoing wealth and riches, living out of one suitcase. He often worked 18 hour days, focusing on new theorems and pushing the boundaries of research.
He often arrived at various universities, knocking on the doors of local math professors' homes in the wee hours. Erdos knocking on your door was not an event any reasonable mathematician snoozed through.
Years later, an interesting phenomenon emerged from the large social network that Erdos built. It is called “The Paul Erdos Number”. Through math communities, it was a game of how many degrees of separation you were from Erdos. What is most interesting: you can trace math competency to how many degrees removed someone is from Erdos. If you are one degree, with him being your teacher, you are assuredly brilliant. If you are two degrees, with your math teacher studying under him, you are still likely very smart. You can see how competency radiates outward like an earthquake.
The lesson is very simple: surround yourself with fantastically competent people in that one skill you are strong in. The saying that you are the average of the five people you spend time with has significance.
Ciao!
