Quotes
~"A mathematician, like a painter or poet, is a maker of patterns. If his patterns are more prominent than theirs, it is because they are made with ideas." [G. H. Hardy, A Mathematician's Apology, 1941.]

~"Technical skill is a master of complexity while creativity is a master of simplicity." [E. Christopher Zeeman (1925)]
