最好的數(shù)學(xué)不僅僅是邏輯的；它是直觀和創(chuàng)造性的，將嚴(yán)謹(jǐn)與想象力結(jié)合在一起。
The best mathematics is not just logical; it is intuitive and creative, blending rigor with imagination.
Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.
藝術(shù)的本質(zhì)功能是道德的。但這是激情、含蓄的道德，不是說教的。這種道德改變的是血液，而不是思想。
