The greatest journeys are those that change us.

我不想成为明星，我想成为传奇。

An understanding of the natural world and what's in it is a source of not only a great curiosity but great fulfillment.

"Every observation we make is a step closer to understanding the cosmos."

写作是一种思考的方式，一种发现你真正相信什么的方式。

书是一个永远不会评判你的朋友。
