A good scientist is like a detective, always looking for clues in the details.

害怕失败的人，注定不会成功。

The only way to achieve the impossible is to believe it is possible.

The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.

存在即是理性。
