A law of nature is the mathematical rela- 

 tionship of a simple cause to its effect, from 

 the statement of which it is possible to deter- 

 mine things, operations, and results otherwise 

 unknown. From the perturbations of Uranus 

 and the law of gravitation, Leverrier located 

 an unseen and previously unknown planet. 

 From the qualities of known elements and 

 the periodic law, Mendeleeff described three 

 primary substances then unknown to science, 

 and gave their compounds, and the qualities 

 of those compounds. 



The laws of nature are of universal applica- 

 tion, and consequently, there is no such thing 

 as an exception to a law of nature. When we 

 find an exception to a generalized statement, 

 that exception is proof that the statement 

 represents usual results from a variable com- 

 posite cause instead of from a simple cause, 

 and hence, that the statement represents a 

 rule and not a law. 



The distinction between a "rule" and a
