Finally, however, the student of the scientific achievement of the war 
period, whether in applications of known laws and perfection and refine- 
ment of existing devices, or in pure research, cannot but be impressed 
by the large body of knowledge and experience which has come as a 
by-product of the study of war problems. During the war both govern- 
ment and private laboratories left no promising clue untraced, and no 
suggestion was ignored if it seemed to contain any germ of expectation. 
Although a large part of this activity did not result in devices or pro- 
cesses directly useful or applicable to war problems, nevertheless out of 
it all is sure to come a wealth of results of value to our scientific and 
industrial life. Now that the immediate need for high pressure research 
is at an end, there should be no decline in the research spirit. Now, 
more than before, the effort should be made to maintain and advance 
the effectiveness of all existing organizations and agencies which en- 
courage and promote diligent research in physics. 
One outgrowth of the intense activity in physical research has been 
a growing interest in physical science and its applications. Our stu- 
dents have been keener and more alert and the instructor has before him 
a wealth of illustrations with which to enrich his classroom and labora- 
tory work. Also in the popular press, setting aside the purely sensa- 
tional, there has been given to the reading public much stimvlating 
material, and the people at large have been brought to a wider appre- 
ciation of scientific laws and facts.
