LOL, I bet he never read "Wealth of Nation"

国富论 was translated by 严复 100 years ago.

A physics professor tried to teach his student about economics should at least read that.

Using TCO to calculate investment return of buying a computer does not make sense. How would any professor calculate a learning experience of computer technology and capture the knowledge spread among generation of students?

Plus, how do you define a 金融上一个封闭系统? Gold standard?

Even with a 金融上一个封闭系统, cash flowis not 守恒，because human activities do create wealth or you can not explain 你把一块钱放进股市这个口袋，拿出来的时候，可能有2块钱.

Guys, it is ok to write something about a good person. It is funny to write something for a person who is not.

LOL
