追求科学不是一种奢侈，而是人类生存的必要条件。

真相很少纯粹，也绝不简单。

Have a heart that never hardens, and a temper that never tires, and a touch that never hurts.

Infinite responsibility is a pathological condition.

We must balance immediate energy needs with long-term sustainability goals.

我对现实不感兴趣。我感兴趣的是现实之外的东西。

雄心不仅带我走得比前人更远，还带我到达我认为人类可能到达的极限。
