I think of a hero as someone who understands the degree of responsibility that comes with his freedom.

All mankind... being all equal and independent, no one ought to harm another in his life, health, liberty or possessions.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but 'That's funny...'

发现的喜悦无疑是人类心灵所能感受到的最活跃的体验。

我认为生活中最重要的事情就是快乐。
