  1. 介绍

A physicist, an engineer, and a computer scientist were discussing the 
nature of God. Surely a Physicist, said the physicist, because 
early in the Creation, God made Light; and you know, Maxwell's equations, 
the dual nature of electro-magnetic waves, the relativist consequences... 
An Engineer!, said the engineer, because before making Light,
 God split the Chaos into Land and Water; it takes a hell of 
an engineer to handle that bigamount of mud, and orderly 
separation of solids from liquids... The computer scientist 
shouted: And the Chaos, where do you think it was coming from, hmm?
