Frasi Paul Erdős

„And the aim is to keep the SF's score low.“

— Paul Erdős
Context: SF means Supreme Fascist — this would show that God is bad. I don't claim that this is correct, or that God exists, but it is just sort of half a joke. … As a joke I said, "What is the purpose of Life?" "Proof and conjecture, and keep the SF's score low." Now, the game with the SF is defined as follows: If you do something bad the SF gets at least two points. If you don't do something good which you could have done, the SF gets at least one point. And if nothing — if you are okay, then no one gets any point. And the aim is to keep the SF's score low. Paul Erdős - SF means Supreme Fascist http://www.youtube.com/watch?v=1qeWugmiGt4

„If numbers aren't beautiful, I don't know what is.“

— Paul Erdős
Frequent remark, as quoted in My Brain Is Open : The Mathematical Journeys of Paul Erdos (1998) by Bruce Schechter, p. 14

„My brain is open!“

— Paul Erdős
A standard greeting he would make when he was not contemplating some mathematical problem, as quoted in My Brain Is Open : The Mathematical Journeys of Paul Erdos (1998) by Bruce Schechter, p. 10

„This one's from the Book!“

— Paul Erdős
Said in regard to any particularly beautiful or elegant proof, referring to a mythical "book" in which God wrote the proofs for all theorems, as quoted in Philosophy of Mathematics (2008) by John Francis, p. 51

„Finally I am becoming stupider no more.“

— Paul Erdős
A suggestion for his own epitaph, as quoted in Variety in Religion and Science: Daily Reflections (2005) by Varadaraja Raman, p. 256

„Some French socialist said that private property was theft … I say that private property is a nuisance.“

— Paul Erdős
Referring to a famous statement by the French anarchist Pierre-Joseph Proudhon that "Property is theft!", as quoted in The Man Who Loved Only Numbers (1998) by Paul Hoffman, p. 7

„The first sign of senility is that a man forgets his theorems, the second sign is that he forgets to zip up, the third sign is that he forgets to zip down.“

— Paul Erdős
Though Erdős used this remark, it is said to have originated with his friend Stanisław Ulam, as reported in The Man Who Loved Only Numbers : The Story of Paul Erdős and the Search for Mathematical Truth (1998) by Paul Hoffman Variants: The first sign of senility is when a man forgets his theorems. The second sign is when he forgets to zip up. The third sign is when he forgets to zip down. As quoted in Wonders of Numbers : Adventures in Mathematics, Mind, and Meaning (2002) by Clifford A. Pickover, p. 64 There are three signs of senility. The first sign is that a man forgets his theorems. The second sign is that he forgets to zip up. The third sign is that he forgets to zip down. No sources found for Erdos stating this, but if he did it is an expression made by many others before him. An example of a common beginning of talks or letters by Paul Erdős; but this is a common mathematical expression. -->

„We'll continue tomorrow — if I live.“

— Paul Erdős
Common remark when breaking off work for the night, as quoted in "The Magician of Budapest" in The Edge of the Universe : Celebrating Ten Years of Math Horizons (2007) by Deanna Haunsperger and Stephen Kennedy, p. 111

„It is not enough to be in the right place at the right time. You should also have an open mind at the right time.“

„A mathematician is a machine for turning coffee into theorems.“

— Paul Erdős
Widely attributed to Erdős, this actually originates with Alfréd Rényi, according to My Brain Is Open : The Mathematical Journeys of Paul Erdos (1998) by Bruce Schechter, p. 155 Variant: A mathematician is a device for turning coffee into theorems.

„God may not play dice with the universe, but something strange is going on with the prime numbers.“

— Paul Erdős
Referencing Albert Einstein's famous remark that "God does not play dice with the universe", this is attributed to Erdős in "Mathematics : Homage to an Itinerant Master" by D. Mackenzie, in Science 275:759 (1997), but has also been stated to be a comment originating in a talk given by Carl Pomerance on the Erdős-Kac theorem, in San Diego in January 1997, a few months after Erdős's death. Confirmation of this by Pomerance is reported in a statement posted to the School of Engineering, Computer Science & Mathematics, University of Exeter http://empslocal.ex.ac.uk/people/staff/mrwatkin//kac-pomerance.txt, where he states it was a paraphrase of something he imagined Erdős and Mark Kac might have said, and presented in a slide-show, which subsequently became reported in a newspaper as a genuine quote of Erdős the next day. In his slide show he had them both reply to Einstein's assertion: "Maybe so, but something is going on with the primes."

„Another roof, another proof.“

— Paul Erdős
His motto, as he roamed about the world, as the guest of other mathematicians, as quoted in A Tribute to Paul Erdős (1990) edited by Alan Baker, Béla Bollobás, A. Hajnal, Preface, p. ix
