The art of disputation is the art of making the worse appear the better reason.

The only thing I fear is God.

未经审视的生活不值得过。

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.

In computational complexity, we are not just dealing with the limits of what we can compute, but also with the limits of what we can prove.

Do you have the time to listen to me whine?

暴风雨过后，天空更晴朗。
