The best way to predict the future is to create it.

The present state of the system of nature is evidently a consequence of what it was in the preceding moment, and if we conceive of an intelligence which at a given instant comprehends all the relations of the entities of this universe, it could state the respective positions, motions, and general effects of all these entities at any time in the past or future.

True leadership means making tough decisions today for a better tomorrow.

要在科学上成功，你需要对真理有热情。
