mathematical elegance
  قشنگی ِ مزداهیک   
qašangi-ye mazdâhik

Fr.: élégance mathématique   

A mathematical solution or demonstration when it yields a result in a surprising way (e.g., from apparently unrelated theorems), is short, and is based on fundamental concepts. According to Henri Poincaré, what gives the feeling of elegance "is the harmony of the different parts, their symmetry, and their happy adjustment; it is, in a word, all that introduces order, all that gives them unity, that enables us to obtain a clear comprehension of the whole as well as of the parts. ... Elegance may result from the feeling of surprise caused by the un-looked-for occurrence together of objects not habitually associated. ... Briefly stated, the sentiment of mathematical elegance is nothing but the satisfaction due to some conformity between the solution we wish to discover and the necessities of our mind" (Henri Poincaré, Science and Method, 1908). According to Bertrand Russell, "Mathematics, rightly viewed, possesses not only truth, but supreme beauty -- a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show" (Bertrand Russell, A History of Western Philosophy, 1945).
