Everything that happens once can never happen again. But everything that happens twice will surely happen a third time.
所有发生过一次的事物都不会再发生。但是所有发生过两次的事物必定会第三次发生。
Civilization is a stream with banks. The stream is sometimes filled with blood from people killing, stealing, shouting and doing the things historians usually record, while on the banks, unnoticed, people build homes, make love, raise children, sing songs, write poetry and even whittle statues. The story of civilization is the story of what happened on the banks.
The only way to achieve the impossible is to believe it is possible.

"The true power of science lies in its ability to unite us in our quest for knowledge."
