Furman University Mathematical Quotation Server - random or searchable math quotes.
In many cases, mathematics is an escape from reality. The mathematician finds his own monastic niche and happiness in pursuits that are disconnected from external affairs. Some practice it as if using a drug. Chess sometimes plays a similar role. In their unhappiness over the events of this world, some immerse themselves in a kind of self-sufficiency in mathematics. (Some have engaged in it for this reason alone.) Adventures of a Mathematician, Scribner& ,s, New York, 1976..

Raleigh NC Rome Press Inc., 1988..Mathematics has beauties of its own -- a symmetry and proportion in its results, a lack of superfluity, an exact adaptation of means to ends, which is exceedingly remarkable and to be found only in the works of the greatest beauty When this subject is properly . presented, the mental emotion should be that of enjoyment of beauty, not that of repulsion from the ugly and the unpleasant.

Representative traditional Japanese patterns. For long, I could not check an example of type p3 among traditional Japanese patterns. However, in the end of 2002, Professor Amiko Tone and Professor Sezo Kondo at Kyoto Furitsu University informed me that examples of type p3 among traditional Japanese patterns actually exist.

Formulas for A,B,C and D. This, unfortunately, is pretty typical of most of the solutions of this problem. We end up with a chain of substitutions leading back to extremely complex formulas with no attempt to condense or simplify them. And since D is wholly dependent on A, B, and C, there should be no more than three independent variables... Since cubes can be negative, this is merely a slight rearrangement of the formula above..Below is a table of cube sums for a and b less than 100..If we look
