than a recitation of incontestable experimental observations. 

 On the other hand, in our day, an "explanation" also has to be 

 less than metaphysical, i.e., it must restrict itself to words and 

 concepts which can be found in good textbooks of mathematics, 

 physics, and chemistry. Within these two constraints the dili- 

 gent invent a theory, and the genius invents the theory; that is 

 why this essay is entitled as it is.
