I remember my friend Johnny von Neumann used to say, 'with four parameters I can fit an elephant, and with five I can make him wiggle his trunk.'

"The most important thing in science is not so much to obtain new facts as to discover new ways of thinking about them."

一个理论最重要的在于其预测的有效性，而非其美学吸引力。

改变始于决定，但靠行动维持。
