Ivars Peterson's MathLand: Paul Erdos: An Infinity of Problems Paul Erdos died of a heart attack on Sept. 20 at the age of 83. Erdos made his initial mark as a mathematician at the age of 18, when he discovered an elegant proof of the theorem that, for each integer greater than 1, there is always a prime number between it, n, and double the number, 2n.

Paul Erdős - Wikipedia, the free encyclopedia Paul Erdős also Pál Erdős, in English Paul Erdos or Paul Erdös, (March 26, 1913 – September 20, 1996) was an immensely prolific (and famously eccentric) Hungarian mathematician who, with hundreds of collaborators, worked on problems in combinatorics, graph theory, number theory, classical analysis, approximation theory, set theory and probability theory. Erdos found a proof for Bertrand's postulate which proved to be far neater than Chebyshev's original one. Because of his prolific output, friends created the Erdős number as a humorous tribute; Erdős alone was assigned the Erdős number of 0 (for being himself), while his immediate collaborators could claim an Erdős number of 1, their collaborators have Erdős number at most 2, and so on. en.wikipedia.org /wiki/Paul_Erdos   (1137 words)

Paul Erdos Paul Erdos was a Hungarian born mathematician famous for his brilliantly elegant proofs of seemingly unsolvable mathematical problems, especially in the area of numbers theory. So thoroughly did Erdos devote himself to mathematics that he never married, acquired no property beyond a change of clothes ("Property is a nuisance."), and he refused to stay tied down to a job because it would limit his ability to focus on mathematical problems and to collaborate with distant colleagues. Erdos on Graphs: His Legacy of Unsolved Problems by Fan Chung and Ron Graham is, as the title suggests, an update on a group of mathematical problems which Erdos had posed to other mathematicians that are still in progress. www.nndb.com /people/401/000032305   (645 words)

Paul Erdos 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 on Friday in Warsaw. Erdos was born into a Hungarian-Jewish family in Budapest, the only surviving child of two mathematics teachers (his two sisters, who died of scarlet fever, were considered even brighter than he was). Erdos had made his first significant contribution to number theory when he was 20, and discovered an elegant proof for the theorem which states that for each number greater than 1, there is always at least one prime number between it and its double. www.cise.ufl.edu /~ddd/erdos.html   (2237 words)

Paulos reviews Paul Erdos, John Nash books   (Site not responding. Last check: 2007-10-11) 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. Erdos simplified the proof and showed that (provided N is at least 7) there were always at least two primes between N and 2N and that they had certain other properties as well. Erdos emerges from all the anecdotes, theorems and travel as quirky, generous, single-minded and incapable of being regimented. www.math.temple.edu /~paulos/erdnash.html   (1966 words)

Last check: 2007-10-11) Erdos was one of the most brilliant and prolific pure mathematicians of the 20th century, and yet had little need of the everyday things that most of us take for granted. Erdos is portrayed as narrowly obsessed with mathematics, to the point of almost being a freak. Erdos was a classic eccentric whose whole life was spent, almost to the exclusion of everything else, in the pursuit of mathematical truth through formal proofs. www.amazon.co.uk /exec/obidos/ASIN/1857028295   (2033 words)

Erdos-Bacon Numbers   (Site not responding. Last check: 2007-10-11) Paul Erdos was a prolific mathematician who wrote academic papers with a total of 502 co-authors, more than twice as many co-authors as any other mathematician. So if you wrote a paper with Erdos, then you have an Erdos number of 1, and if you wrote a paper with someone who wrote a paper with Erdos then you have an Erdos number of 2, and so on. In theory, she could achieve an Erdos number of 2 - it is too late to get an Erdos number of 1 because Erdos died some years ago. www.simonsingh.com /Erdos-Bacon_Numbers.html   (838 words)

[No title] Paul Erdos If the Martians had made contact with earth during the lifetime of Paul Erdos he would have made a good choice as this planet's ambassador. In his prime Paul Erdos's parents were maths teachers, so they presumably looked at him fondly when, at four, he said he had discovered negative numbers.

Last check: 2007-10-11) Paul Erdös was an amazing and prolific mathematician whose life as a world-wandering numerical nomad was legendary. Paul Erdos' position in number theory of the 20th century is pretty much like Miles Davis' in jazz: in some way or another every important figure in number theory has worked with Erdos, much like every influential jazz musician collaborated with Davis at one point in their respective careers.

Erdos numbers go as high as 16 and the number of people with an Erdos number is said to be well above 100,000. This book covered much of the life and mathematics of Paul Erdos; much of the mathematics in the book is number theory because it is a topic that is easy for anyone to understand yet difficult to prove. www.amazon.ca /exec/obidos/ASIN/0684859807   (1624 words)
