  Paul Erdos   (Site not responding. Last check: 2007-10-08)
Paul Erdos, one of this century' greatest mathematicians, was born in Budapest on March 26, 1913.
Erdos discovered a less complex proof for the theorem which states '' each number greater than 1, there is always one prime number between it and its double'' (The Times).
Erdos typically greeted people with a difficult problem, and for many mathematicians who solved these problems, he gave them prizes of up to $1000.

 Paul Erdos
Erdos had given away most of the money he earned from lecturing at mathematics conferences, donating it to students or as prizes for solving problems he had posed.
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.

Erdos enjoyed offering monetary rewards for solving particular problems, ranging from $10,000 for what he called "a hopeless problem" in number theory to $25 for something that he considered not particularly difficult but still tricky, proposed in the middle of a lecture.

 Paulos reviews Paul Erdos, John Nash books
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.

 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 process.

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.
Thus, the implication that Erdos' physical clumsiness and difficulties with certain practical activities were due solely to a narrow focus on mathematics is both unfair to Erdos personally and a disservice to the many less eminent people who are physically clumsy or have other specific cognitive or motor difficulties.

 35 Wn. App. 225, BACHE HALSEY STUART SHIELDS v. ERDOS
Erdos contends that the governing standard of review is whether the findings are supported by substantial evidence and, if so, whether the findings in turn support the trial court's conclusions of law and judgment.
Erdos has not assigned error to this portion of the finding of fact and it is a verity on appeal.
Erdos contends that the trial court erred in concluding that Bache properly liquidated Erdos' account prior to formal presentment of the checks he had delivered on October 25 and 26, 1978, in response to Bache's margin calls.

The divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, and 110, which all sum to 284; the divisors of 284 are 1, 2, 4, 71, and 142, which all sum to 220.
Erdos also came up with other theorems, such as the Erdos-Kac and the Erdos-Wintner theorems, which are two probabilistic theorems on additive functions.

 AllRefer.com - Paul ErdOs (Mathematics, Biography) - Encyclopedia
ErdOs wrote about 1,500 papers, about five times as many as other prolific mathematicians, and had about 500 collaborators.
He wrote fundamental papers on real analysis, geometry, topology, probability theory, complex analysis, approximation theory, and set theory, but he will be remembered best for his contributions to number theory and combinatorics, an area of mathematics fundamental to computer science.
See A. Baker et al., A Tribute to Paul ErdOs (1991); A. Thomason, Combinatorics, Geometry, and Probability (1997); K. Alladi et al., Analytic and Elementary Number Theory (1998); B. Schechter, My Brain Is Open (1998); P. Hoffman, The Man Who Loved Only Numbers (1998).

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.

In the shadows stood the discreet and elegant Thomas Erdos, a man of such taste, tact, and consideration that the word “agent” does not seem applicable to him.
During the 50s and 60s, Thomas Erdos was the major force behind the Festival at Baalbek in Lebanon, and then at Cheraz-Persepolis in Iran, where he met Soudaleh Kia, who was to become his collaborator.

I have heard there is another biography of Erdos out there that deals more directly with his life and ideas, and if one were looking for a more focused biography, it would probably be a better choice.
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.

 Marcos in GT Racing 2000   (Site not responding. Last check: 2007-10-08)
Erdos' car was not a contender for pole (it started 7th), running a 'V7' as it bedded in and the late rebuild of the second NCK car saw it restricted to 10th overall.
Erdos quickly got his car up into 4th ahead of Tim Harvey in a GT2 Porsche, but the engine started giving problems and Thomas pulled in early to retire rather than risk yet another NCK engine failure - at least his done some race laps now....
However, it was Erdos who took third for best Marcos on the grid, after he ran faster in the dying moments of the first session.
