If you had written a joint paper with someone with ErdÃƒÂ¶s number 1, your ErdÃƒÂ¶s number is 2, and so on inductively. A genius in the true sense of the word, Erdos traveled the world, living out of a suitcase, to problem solve--and problem pose--with his mathematical peers. Number theory, combinatorics a branch of mathematics concerning the arrangement of finite sets , and discrete mathematics were his consuming passions. Regardless, it is a wonderful video. Those that were active in research admired his mathematical accomplishments, while others on the faculty were amused by his eccentricities. If someone had worked with another who had worked with Erdos, their Erdos number was two, and so on. What about the prime numbers? It may not seem of any use now or next year.

He could not pass a homeless person without giving him money. He spent much of the next ten years in Israel. He was always asking me to send some of them to one person or another. Erdos' main area of expertise was number theory. The number is incomprehensibly large.

When I picked him up at the airport, what struck me first was that he had a suitcase! Strauss died in 1983 and was replaced by Bruce Rothschild. His appearances were irregular, owing to the fact that he had no formal arrangements with any of the schools he visited. Mathematics is the oldest science and the foundation of all human knowledge. He was angry with himself for letting his friends slip out of sight. The doctor informed us that he had two heart attacks and the second one killed him.

The jest referred to the ErdÅ‘s-Kac theorem. So why does he figure so prominently? When ErdÃ¶s heard the limerick, he wanted to publish a paper in Kurdish but couldn't find a Kurdish math journal. The book is full of fun anecdotes in his life and plainly explains interesting facts and concepts of number theory one of his main fields of work. Included in that long list is Norbert Wiener 1894-1964 , born in the United States and one of the earliest American contributors to control theory, which he called cybernetics. He was fascinated by numbers from an early age, and by the time he was 20, he was known as The Magician from Budapest. To ErdÃƒÂ¶s, being denied the right to travel was like being denied the right to breathe, so he went to Amsterdam anyway.

This book is about a mathematician and his life with numbers, an idea so esoteric mere humans such as myself cannot comprehend it. ErdÅ‘s, Fan Chung, and her husband Ronald Graham, Japan 1986 , then a nation, was under the of the. The book can be ordered from. Reading this, I actually got really into certain math problems the infamous Monty Hall problem for example. He never married and left no immediate survivors. Graham and others worried about his habit and prevailed upon him to quit, apparently with little result.

A human look at the Hungarian mathematician Paul Erdos who loved numbers more than anything. I'd also like the book has tried to explain the connections of the geometry of elliptic curves, the algebra of Diophantine equations and the Wiles's proof of the Fermat's Last Theorem. He has done research in algebra and general topology. Arnold Ross, the chairman of the Mathematics Department, had arranged for him to teach only one advanced course, and supplied an assistant who could take over his class if he had the urge to travel to talk with a collaborator. His two older sisters died of scarlet fever when he was an infant, leaving him an only child with a very protective mother. After this paper was written, collaborator Lovasz received the Wolf prize, making 2 in all.

So, was it only the fear of not being let out of Hungary that stopped him going there. And a run on the bank is much more likely than solutions to all my problems. And, his friends say, he was also one of the most unusual. He was stricken while attending a conference. He also has a paper called and another entitled. As Wayne Baker indicates in , mathematicians put their Erdos numbers on their resumes. Biography Hungarian mathematician who became perhaps one of the most prolific from the twentieth century, having composing a lot more than 1,500 mathematical articles during his career.

Like a medieval monk, or better said a Galacian rabbi, Erdos lived solely for the infinite cause of mathematical understanding. His world of mathematics became the world we all entered. There is also the Paul ErdÃ¶s who was a long-time market research executive and an authority on mail surveys. This showed, with the use of computers, that any two dimensional map can be filled in with four colors without any adjacent countries showing the same color. It includes a letter from ErdÃ¶s to Klarner. Mathematicians, unlike other scientists, require no laboratory equipment--a practice that reportedly began with Archimedes, who, after emerging from his bath and rubbing himself with olive oil, discovered the principles of geometry by using his fingernails to trace figures on his oily skin. He used coffee, Benzedrine and caffeine tablets to stay awake.

If someone had worked with another who had worked with Erdos, their Erdos number was two, and so on. Cosseted by his mother and by household servants, he was not brought up to fend for himself. A genius in the true sense of the word, Erdos traveled the world, living out of a suitcase, to problem solveâ€”and problem poseâ€”with his mathematical peers. He just trusted that I, a total stranger, would get him there. The earliest efforts to ascend from superstition to reason came about because men discovered mathematics while studying the stars. ErdÃ¶s's curiosity about food, like his approach to so many things, was merely theoretical. If you published a paper with a person who's a 1, you're a 2, and so on.

When the name of a colleague in California came up at breakfast in New Jersey, ErdÃ¶s remembered a mathematical result he wanted to share with him. There is now an home page on the web where you can see a list of all who have an Edos number of 1 there are 462 of us and 2 all 4566 of them, including Albert Einstein. My inability to do mathematics has always made me feel stupid, and it does so to a somewhat smaller degree today as well. Sometimes I could hardly talk to him because he was surrounded by mathematicians eager to ask him questions, but when I could, he inquired about mutual friends and asked about follow-up work on our paper and progress about solving the open problems we had posed. But it doesn't stop on the life and, perhaps less so, work of the prolific mathematician. But most of all, I will just miss Paul, the human.
