George Polya's tips for problem solving: (from How to Solve It
HOW TO SOLVE IT
UNDERSTANDING THE PROBLEM First. You have to understand the problem. What is the unknown? What are the data? What is the condition? Is it possible to satisfy the condition? Is the condition sufficient to determine the unknown? Or is it insufficient? Or redundant? Or contradictory? Draw a figure. Introduce suitable notation. Separate the various parts of the condition. Can you write them down? DEVISING A PLAN Second. Find the connection between the data and the unknown. You may be obliged to consider auxiliary problems if an immediate connection cannot be found. You should obtain eventually a plan of the solution. Have you seen it before? Or have you seen the same problem in a slightly different form? Do you know a related problem? Do you know a theorem that could be useful? Look at the unknown! And try to think of a familiar problem having the same or a similar unknown. Here is a problem related to yours and solved before. Could you use it? Could you use its result? Could you use its method? Should you introduce some auxiliary element in order to make its use possible?

    http://www.amt.canberra.edu.au/polya.html
    George Pólya (1887-1985) As a student George attended a state run high school with a good academic reputation. He was physically strong and participated in various sports. His school had a strong emphasis on learning from memory, a technique which he found tedious at the time but later found useful. He was not particularly interested in mathematics in the younger years. Whereas he knew about the Eötvös Competition and apparently wrote it he also apparently failed to hand in his paper. He graduated from Marko Street Gymnasium in 1905, ranking among the top four students and earning a scholarship to the University of Budapest, which he entered in 1905. He commenced studying law, emulating his father, but found this study boring and changed to language and literature. He had become particularly interested in Latin and Hungarian, where he had had good teachers. He also began studying physics, mathematics and philosophy. His development was greatly influenced by the legendary mathematician Lipót Fejér, a man also of wit and humour, who also taught Riesz, Szegö and Erdös. Fejér had discovered his theorem on the arithmetic mean of Fourier Series at the age of 20. Pólya soon concentrated his studies on mathematics and in 1910 finished his doctorate studies, except for his dissertation. He took a year in Vienna and returned to Budapest in 1911-12 to give his doctoral dissertation and met Gábor Szegö, seven years younger, who was to become one of his major collaborators.

    The Random Walks of George Polya
    George Pólya, Gerald L. Alexanderson
    In stock Only for sale in Australia, United Kingdom, Ireland, New Zealand, South Africa, United States of America George Pólya was one of the giants of classical analysis in the 20th century, and the influence of his work can be seen far beyond analysis, into number theory, geometry, probability and combinatorics. This book serves both as a biography of Pólya’s life, and a review of his many mathematical achievements by experts from a wide range of different fields. Last but not least the book finishes with two essays by Pólya himself which focus on how to learn to solve problems, a subject with which he was fascinated throughout his life.

    problems worthy of attack
    proves their worth
    by hitting back
    Piet Hein The simple idea. To make simple things difficult is easy and requires only a confused mind or lack of thinking. To keep things simple, on the other hand, is hard and requires effort and imagination. Every child knows that questions come before answers, it is not the other way around. This does not happen every day: 'Vanessa,' she answered. 'What is your name,' he asked. However, this happens every day: 'To find the interest, you multiply the principal by the rate and by the number of days. Finally you divide by 100 and 360,' the teacher answers. 'How much interest will a capital of $4,500 earn in 190 days if the rate is 5%?' the teacher asks. There is something fundamentally wrong here. The teacher started with the answer and then raised the question. This is a simple article. It has only one idea. The idea has already been explained. Here it comes again: 'Questions come before answers.'

    Guessing is good for you Checklists are good. They keep you focused. In his book Mathematical Discovery, George Polya, suggests this checklist, or ten commandments, for math teachers. Do you agree with, sin against, many of them?
  • Be interested in your subject Know your subject Know about the ways of learning: The best way to learn anything is to discover it by yourself Try to read the faces of your students, try to see their expectations and difficulties, put yourself in their place. Give them not only information, but "know-how," attitudes of mind, the habit of methodical work. Let them learn guessing. Let them learn proving. Look for such features of the problem at hand as may be useful in solving the problems to come - try to disclose the general pattern that lies behind the present concrete situation. Do not give away your whole secret at once - let the students guess before you tell it. Let them find out by themselves as much as is feasible. Suggest it, do not force it down their throats.

    Correspondence with george polya The two letters by polya (18871985) werewritten when he was 94. Andrew Odlyzko to george polya, December 8, 1981
    http://www.dtc.umn.edu/~odlyzko/polya/
    Andrew Odlyzko: Correspondence about the origins of the Hilbert-Polya Conjecture
  • The Hilbert-Polya Conjecture says that the Riemann Hypothesis is true because non-trivial zeros of the zeta function correspond (in a certain canonical way) to the eigenvalues of some positive operator. This conjecture is often regarded as the most promising way to prove the Riemann Hypothesis. Very little is known about its origins. Mathematical folk wisdom has usually attributed its formulation to Hilbert and Polya, independently, some time in the 1910s. However, there appears to be no published mention of it before Hugh Montgomery's 1973 paper on the pair correlation of zeros of the zeta function. Enclosed here are copies of some letters that attempted to trace the history of the Hilbert-Polya Conjecture. The first letter from Polya appears to present the only documented evidence about the origins of the conjecture.
  • Correspondence with George Polya: The two letters by Polya (1887-1985) were written when he was 94. According to N. G. de Bruijn, at that stage in his life, Polya usually dictated letters to his wife, and only signed them himself. The fact that he wrote both letters out in his own handwriting suggests he was very interested in the subject. The account of the formulation of the conjecture in the first letter is consistent with what Polya had told Dennis Hejhal in a personal conversation.
