"In mathematics, you don't understand things. You just get used to them."

"Humor is a way of dealing with the world, a way of coping with the world, and a way of understanding the world."

It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us, we had nothing before us, we were all going direct to Heaven, we were all doing direct the other way.

眼睛不仅是光学器官，更是灵魂的居所与心灵的窗口。

Was vernünftig ist， das ist Wirklich； und was wirklich ist，das ist vernünftig.

我们必须在适应不断变化的市场的同时，忠于我们的核心价值观。

世界上充满了微小的善意，只要你知道在哪里寻找。
