I think about the weight of history.

"You can never know everything, and part of what you know is always wrong."

The past is a map, showing us where we have been.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but 'That's funny...'

"Behind every post is a real person with real feelings—let's not forget that."

如果你没有偶尔失败，那说明你没有在做任何非常创新的事情。
