Coal isn't just a commodity; it's the foundation upon which modern civilization was built.
煤炭不仅仅是一种商品，更是现代文明赖以建立的基础。
What's terrible is to pretend that second-rate is first-rate. To pretend that you don't need love when you do; or you like your work when you know quite well you're capable of better.
The beauty of physics lies in its ability to explain the complex with the simple.
人类大脑是一个复杂的自组织系统。
电影是展示不可见之物的艺术。
——〈在北京湖广会馆学界欢迎会的演说〉，1912年8月30日
