THE RELATIONS BETWEEN ENGI- 

 NEERING AND SCIENCEi 



We may well approach our subject of 

 the relation betM'een engineering and sci- 

 ence by defining these two. 



Engineering is the application to man's 

 use of special knowledge of mechanics and 

 of the properties of matter. 



Natural science is the correlation of nat- 

 ural phenomena, often combined with their 

 discovery. Emerson says: 



Science is nothing but the finding of analogy, 

 identity in the most remote parts. 



This finding of analogy ' is correlation. 

 But though science has correlation for its 

 essence it also includes discovery. Science 

 thus has two aspects, it correlates the un- 

 correlated and hence empirically known 

 phenomena, and it discovers new phenom- 

 ena and correlates them simultaneously. 

 Their correlation is of origin, congenital. 

 Or, if you will not go so far with me, let us 

 agree that engineering is essentially appli- 

 cation and science essentially correlation 

 with or without discovery. In this view 

 engineering is not a science but an* art with 

 a scientific basis. A man who is an engi- 

 neer may correlate his own or others' dis- 

 coveries, as he may walk a mile or pledge 

 a health, but he does it not as an engineer 

 but as simultaneously a natural philosopher. 



From this point of view pure science in
