41. Paul Erdos And Me My experiences with paul erdos. paul erdos who `left' (as he would have phrasedit) last September, was one of the greatest mathematicians of our time. http://www.geocities.com/CapeCanaveral/Lab/3550/erdosfle.htm

My experiences with Paul Erdos - Prof Herbert Fleischner Paul Erdos who `left' (as he would have phrased it) last September, was one of the greatest mathematicians of our time. No doubt. The obituaries have expounded on that, and they also made some remarks on his personality such as his attitude towards owning property (`it's a nuisance'), etc. He was described as an eccentric - which is true if one considers imposed norms as `center'. How can one describe a human being like Erdos to people who have never met this extraordinary man? Was he unreachable? Was he so preoccupied with writing papers (roughly 1500 and more) that he didn't know anything about the non-mathematical world? I think the best way to describe a human being to someone who has never met him, is to describe encounters with such a person, rather than to try to give a general `overall picture' of the person. Well, am I one of the lucky few who have met Erdos? Nonsense! I am one of the lucky many who have met `Uncle Paul'! This is how we would address him during the last so and so many years - "hello, Uncle Paul!", "Excuse me, Uncle Paul,....". He didn't care about being called `Professor Erdos'. This `Uncle Paul' was an expression of our respect for this great man, and of our love for him. I am one of the lucky many...because he was constantly on the move, spending a few weeks here and there, at this or that conference, at this or that university. His homes were with the people he met. He would stay with colleagues whenever possible; only during the last years did he stay in an apartment given to him by the Hungarian Academy of Sciences, whenever he was in native Hungary. But most of the time he was not in Hungary. An anecdote says that many years ago, when he had to fill out a visa application for a trip to the USA, he answered the question: 'Country of Residence' by filling in 'Hungary, USA, Canada, Israel, Australia' and this was not a lie! These were the countries where he could be contacted at the time. Until the 1970's it was his mother who would know at any given time where Erdos could be 'found'; after she died, Ron Graham of Bell Labs (USA) who took over this function (and managed his finances, etc.). 'Uncle Paul' was a true cosmopolitan...

The TIMES September 25, 1996 PAUL ERDOS Paul Erdos, mathematician, died on September 20 aged 83. He was born on March 26, 1913. Paul Erdos was regarded by fellow mathematicians as the most brilliant, if eccentric, mind in his field. Because he had no interest in anything but numbers, his name was not well known outside the mathematical fraternity. He wrote no best-selling books, and showed a stoic disregard for worldly success and personal comfort, living out of a suitcase for much of his adult life. The money he made from prizes he gave away to fellow mathematicians whom he considered to be needier than himself. "Property is a nuisance," was his succinct evaluation. Mathematics was his life and his only interest from earliest childhood onwards. He became the most prolific mathematician of his generation, writing or co-authoring 1,000 papers and still publishing one a week in his seventies. His research spanned many areas, but it was in number theory that he was considered a genius. He set problems that were often easy to state, but extremely tricky to solve and which involved the relationships between numbers. He liked to say that if one could think of a problem in mathematics that was unsolved and more than 100 years old, it was probably a problem in number theory. In spite, or perhaps because of, his eccentricities, mathematicians revered him and found him inspiring to work with. He was regarded as the wit of the mathematical world, the one man capable of coming up with a short, clever solution to a problem on which others had laboured through pages of equations. He collaborated with so many mathematicians that the phenomenon of the "Erdos number" evolved. To have an Erdos number 1, a mathematician must have published a paper with Erdos. To have a number of 2, he or she must have published with someone who had published with Erdos, and so on. Four and a half thousand mathematicians have an Erdos number of 2.

New York Times, September 24, 1996 Paul Erdos, a Math Wayfarer At Field's Pinnacle, Dies at 83 By GINA KOLATA Dr. Paul Erdos, a legendary mathematician who was so devoted to his subject that he lived as a mathematical pilgrim with no home and no job, died Friday in Warsaw, Poland. He was 83. The cause of death was a heart attack, according to an E-mail message sent out this weekend by Dr. Miki Simonovits, a mathematician at the Hungarian Academy of Sciences, who was a close friend. Erdos (pronounced AIR-dosh) was attending a mathematics meeting in Warsaw when he died, Simonovits reported. Never, mathematicians say, has there been an individual like Paul Erdos. He was one of the century's greatest mathematicians, who posed and solved thorny problems in number theory and other areas and founded the field of discrete mathematics, which is the foundation of computer science. He was also one of the most prolific mathematicians in history, with more than 1,500 papers to his name. And, his friends say, he was also one of the most unusual. Erdos, "is on the short list for our century," said Dr. Joel H. Spencer, a mathematician at New York University's Courant Institute of Mathematical Sciences.

The Generosity of Paul Erdos' Game Theory The Generosity of Paul Erdos' is legendary. This quote was taken from Paul Hoffman's 1998 book entitled: "The Man Who Loved Only Numbers: the story of Paul Erdos and the search for mathematical truth," NY:Hyperion, pg.10. In the late 1980s Erdos heard of a promising high school student named Glen Whitney who wanted to study mathematics at Harvard but was a little short of the tuition. Erdos arranged to see him and, convinced of the young man's talent, lent him $1000. He asked Whitney to pay him back only when it would not cause financial strain. A decade later Graham heard from Whitney, who as last had the money to repay Erdos. "Did Erdos expect me to pay interest?" Whitney wondered. "What should I do?" he asked Graham. Graham talked to Erdos. "Tell him," Erdos said, "to do with the thousand dollars what I did."

Paul Erdos is dead On 20 September 1996, one of the best mathematicians of our time died. Paul Erdos was attending a combinatorics conference when he suffered a double heart attack and died a few hours later. He was not exactly like most other human beings. He didn't have a home, though he could afford one. Instead he had a network of friends all over the world with whom he'd stay. He'd just drop in suddenly and say ``My brain is open''. Without hesitation, his surprised friends would invite him in! He thought money was a nuisance, and gave most of it away (if only this wasn't unusual among humans!) He loved simple solutions to problems. More importantly, he could find them as well. He once heard that two mathematicians had produced a 30 page proof of a theorem. After ten minutes, he produced a two line proof! Wouldn't you like to read more about him? There were several obituaries for him, even by commercial magazines and newspapers who normally pay no attention to maths.

52. Obituary -- Paul Erdos Obituary paul Erdö Throughout his life, paul Erdös never seemed to age.I first met him in the early sixties, and I last saw him a few months ago. http://www.siam.org/siamnews/obits/erdos.htm

In the second half of his life, his lectures invariably had the same title: "Problems in Combinatorics and Number Theory." The content of the lectures varied as the problems he had proposed were solved and new problems were added. He was shrewd enough to propose problems that could be solved by good mathematicians with the techniques of the day; only on occasion would he state a problem that he knew would require a genuinely new idea, and then he would offer an unusually large sum for its solution. If we were to include among his publications those inspired by his valuable hints, we should have to increase the number of his published papers from fifteen hundred to tens of thousands. He was good at sizing up people. His incisive remarks on personalities, casually stated in the middle of a mathematical argument, were invariably surprising and always true, though they never hurt. His elementary proof of the prime number theorem (with Selberg) is often cited as some of his best work. Actually, several of his ideas are more likely to survive than many of the theorems: His idea of proving the existence of combinatorial objects by probabilistic methods and his infinite Ramsey theory are two of many thriving chapters of mathematics that he initiated, and that are a long way from being concluded.

55. Paulos Reviews Paul Erdos, John Nash Books I was awake enough to realize that it was paul erdos, one of the most curious(in both senses), prolific and insightful mathematicians of this century. http://www.math.temple.edu/~paulos/erdnash.html

I remember once while in graduate school at the University of Wisconsin staying at my office until 4 a.m. Stumbling through the hall bleary-eyed on my way home, I came upon a little gnome of a man who, as if it were the middle of the day, began questioning me about my results in a kindly yet most energetic way. Who should be haunting those empty halls at that hour, except janitors? I was awake enough to realize that it was Paul Erdos, one of the most curious (in both senses), prolific and insightful mathematicians of this century. It's not surprising that Erdos would often remark that a mathematician was a machine for turning coffee into theorems. Toward the end of his life he even partook of amphetamines to keep his mental machinery churning into the wee hours. Such eccentricity in the men who study circles and numbers is only part of the story of mathematicians Erdos and John Nash, the subjects of the new biographies "My Brain Is Open," "The Man Who Loved Only Numbers" and "A Beautiful Mind." But for many, the eccentricity may be the most intriguing part. Science writer Bruce Schechter's "My Brain Is Open" is a mathematical biography of Erdos, born in 1913 in Hungary to academic parents. Erdos was cosseted by a mother who had just lost her other two children to scarlet fever and educated by a father who early on taught him about prime numbers and infinite sets. Both influences were life-defining. In later years he related how he independently discovered the notion of negative numbers at the age of 3 but didn't butter his own toast until he was 20.

Considered by many as one of the great mathematicians of this century and certainly one of the most prolific ever, he will be missed. For more than 50 years, Erdos wandered the globe visiting mathematicians, attending meetings, teaching, and lecturing. He had become the center of an enormous web of collaboration. "One never knew where Erdos was, not even the country," Richard Bellman wrote in Eye of the Hurricane. "However, one could be sure that during the year ... Erdos was everywhere. He was the nearest thing to an ergodic particle that a human being could be." At his death, Erdos had more than 1,500 published papers to his credit...
