Is a humorous non-mathematical book about him. Erdos was a funny and strange man. He was the most prolific co-writer of math papers.
He didn't have a home, but would just pack his bags and sleep over at other mathematicians couches around the world. He would ask about their math interests and problems. Erdos often had some great insights and unusual perspectives about it. He would talk about math with them non stop, until they could take no more. The other mathematician would often write a paper about what they had discussed, and Erdos would be sent on his way to the next mathematician.
When he discovered or heard about some very beautiful proof. He would say this proof was "from The book". As in the book that God wrote. He also called God the supreme fascist.
Erdos dint sleep much and didnt care about things that where not math. He couldn't tie his shoes, liked to tell silly jokes, and was a virgin. He was also on amphetamines most of the time.
