化学不仅是一门科学，它是一种看待世界的方式。

我像个孩子。我从不考虑后果。

Stray birds of summer come to my window to sing and fly away. And yellow leaves of autumn, which have no songs,flutter and fall there with a sigh.

梦想不是追逐的，而是创造的。

We are all travelers in the wilderness of this world, and the best we can find in our travels is an honest friend.
