THE RELATION OF MATHEMATICS TO 

 ENGINEERING. 



A FEW years ago technical education as 

 we now understand it was unknown in 

 America. We have now in our midst more 

 than 20,000 students preparing themselves 

 distinctively for the engineering profession. 



Wliile the technical schools of the country 

 have had a development which for rapidity, 

 strength and importance is little short of 

 marvelous, yet their rise and growth have 

 been profoundly influencing the thought as 

 well as the welfare of the nation. Es- 

 pecially in the domain of mathematics have 

 they had a directing and vivifying influence 

 which is little short of a revolution. To- 

 day mathematics wishes no stronger reason 

 for her existence and no stronger call to her 

 cultivation than the fact that she is the un- 

 challenged doorkeeper to the appreciation 

 and mastery of the physical sciences, both 

 in their theory and in their application by 

 the engineer to things useful. 



The time is past when mathematics is re- 

 ferred to by the thinkers of the day as 

 being principally a discipline. It is of 

 course true that, rightly pursued, mathe-. 

 matics is a discipline, but it is far more, it 

 is a knowledge, a tool, a power, a civilizer. 

 The day is gone when, on the one hand, the 

 student, Chinese fashion, learns his geom- 

 etry word for word from cover to cover 

 or memorizes all the propositions of his
