学生对老师说，

Teacher, I believe that I have found the nature of the empty string. The empty string is like a particle of dust, and it floats freely through a string as dust floats freely through the room, glistening in a beam of sunlight.

嗯。一个好的概念。现在告诉我，灰尘在哪里，阳光在哪里？

Hmm. A fine notion. Now tell me, where is the dust, and where is the sunlight?
