Imaginary Erdős Number: What is that?

Students studying Mathematics at university will sooner or later hear of the famous eccentric Mathematician Paul Erdos, and the concept of Erdos Number. People who have written a paper with Erdos have a Erdos number of 1. People who have cowritten with the above people (with Erdos number 1), have Erdos number 2. Unfortunately, it is now impossible to get Erdos number 1, as Paul Erdos has passed away.

But what is an Imaginary Erdos Number?

This YouTube channel Numberphile has really succeeded in making Maths interesting! I watch almost every new episode that comes out, and will feature it on my website.

MY BRAIN IS OPEN: The Mathematical Journeys of Paul Erdos

Paul Erdõs, one of the greatest mathematicians of the twentieth century, and certainly the most eccentric, was internationally recognized as a prodigy by age seventeen. Hungarian-born Erdõs believed that the meaning of life was to prove and conjecture. His work in the United States and all over the world has earned him the titles of the century’s leading number theorist and the most prolific mathematician who ever lived. Erdõs’s important work has proved pivotal to the development of computer science, and his unique personality makes him an unforgettable character in the world of mathematics. Incapable of the smallest of household tasks and having no permanent home or job, he was sustained by the generosity of colleagues and by his own belief in the beauty of numbers.
Witty and filled with the sort of mathematical puzzles that intrigued Erdõs and continue to fascinate mathematicians today, My Brain Is Open is the story of this strange genius and a journey in his footsteps through the world of mathematics, where universal truths await discovery like hidden treasures and where brilliant proofs are poetry.
