SCIENCE AND INDUSTRY 3 



science was to be an important factor in 

 success, and while against the heroism of our 

 men all that the science of our foes could do 

 proved unavailing, it was clear that bravery 

 and self-sacrifice without the aid which science 

 could bring would fail to give us victory. Let 

 me remind you of some few of the methods in 

 which scientific investigation has aided our 

 cause ; they are so obvious as to need little 

 more than a passing reference. 



Take flying, for example, every part of a 

 modern aeroplane is the product of a highly 

 specialised science. In the machine itself, to 

 combine strength with lightness, to select the 

 right material for each part, to design the 

 wings so that they may bear the greatest 

 weight and offer the least resistance to the 

 motion, to give the body ample strength to 

 withstand the shocks of alighting and yet not 

 weight the machine unduly all these points
