The true essence of scientific discovery is not in the answers it provides, but in the new questions it raises.
科学发现的真正本质不在于它提供的答案，而在于它提出的新问题。
If you think you saw a mouse， you did. And， if there is one， there are more.
We must always question our assumptions and be willing to revise our understanding in light of new evidence.
过去总是紧张的，未来是完美的。
