数学不仅仅是关于数字、方程、计算或算法：它是关于理解的。
Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.
Life is short and you have to keep moving forward.

The Worldly Hope men set their Hearts upon Turns Ashes—or it prospers; and anon, Like Snow upon the Desert's dusty Face, Lighting a little hour or two—is gone.
我们都在同一条船上，这就是我们要传达的信息。
