A mathematician, like a painter or a poet, is a maker of patterns... The mathematician`s patterns, like the painter`s or the poet`s, must be beautiful; the ideas, like the colours or the words, must fit together in a harmonious way. Beauty is the first test: there is no permanent place in the world for ugly mathematics. -G.H. Hardy It seems that if one is working from the point of view of getting beauty into one`s equation, and if one has really a sound insight, one is on a sure line of progress. - P.A.M. Dirac ©
