理論物理學實際上是哲學。

譯文：感嘆白發，觀察世間的道路。人們無不追求榮華，看重富貴而輕視貧賤。顯赫的宮門，華麗的宮殿。年輕時入仕，幼年時就獻上謀略。

A fisherman’s wisdom is as valuable as any scientist’s data.

We live in the best of all possible worlds because it was chosen from all possible worlds.

農業的未來在于可持續發展，我們要為子孫后代留下綠水青山。

You can't just sit there and wait for people to give you that golden dream. You've got to get out there and make it happen for yourself.
