NUMERICAL LAWS AND MATHEMATICS 



Suppose you found a page with the following marks on 

 it never mind if they mean anything : 



d Y dp dX dy dp 



dy d/, dt dy dz 



da d Y dY doc d Y 



dz dx dt dz dx 



dp da dZ dp da 



dx dy dt dx dy 



dx dY dZ da dY dZ 



dt dz dy dt dz dy 



dp dZ dX dp dZ dX 



dt dx dz dt dx dz 



d Y dX dY dv dX dY 



dt dy dx dt dy dx 



I think you would see that the set of symbols on the 

 right side are " prettier " in some sense than those on 

 the left ; they arc more symmetrical. Well, the great 

 physicist, James Clerk Maxwell, about 1870, thought 

 so too ; and by substituting the symbols on the right 

 side for those on the left, he founded modern physics, 

 and, among other practical results, made wireless 



raphy possible. 



It sounds incredible ; and I must try to explain a littlr 

 more. The symbols on the left side represent two 

 \\vll lectrical laws : Ampere's Law and Faraday's 



ry suggested by an an.do^v with
