量子世界和经典世界之间的边界不是一条清晰的线，而是一个模糊的过渡，物理规则在这里发生了戏剧性的变化。
"The boundary between the quantum and classical worlds is not a sharp line but a blurred transition where the rules of physics shift dramatically."
预见数学未来的真正方法是研究它的历史和现状。
预测未来的最好方法就是去创造它。
Old paint on canvas, as it ages, sometimes becomes transparent. When that happens it is possible, in some pictures, to see the original lines: a tree will show through a woman's dress, a child makes way for a dog, a large boat is no longer on an open sea. That is called pentimento because the painter 'repented,' changed his mind. Perhaps it would be as well to say that the old conception, replaced by a later choice, is a way of seeing and then seeing again.
The most important thing in life is to be happy.
