MIRACLES OF SCIENCE 



a something 1TOO times smaller than the hydrogen 

 atom; the proof that light is a form of electromag- 

 netism; five new gases in the atmosphere; the exact 

 measurement of light-waves, to the millionth of an 

 inch; the proof that carbon can be transformed into 

 diamond in the electric arc; the explanation of the 

 manner of brain cell activity that underlies the pro- 

 cesses of thought ; explanations of world-building 

 based on a new theory of light-pressure; and sundry 

 analyses of the chemical properties of living matter 

 that cannot be characterized in a phrase. 



If to this list of achievements in theoretical science 

 we add such practical accomplishments as the per- 

 fection of the wireless telegraph; the development 

 of antitoxin, tuberculin, and the Finsen ray; new 

 studies of digestive and assimilative processes; ex- 

 planations of the mechanism through which the body 

 fights disease ; and the transplanting of living organs, 

 we shall gain at least an inkling of the wide scope 

 of the new knowledge, as recognized by the Nobel 

 Foundation. 



It may well be doubted whether any single gen- 

 eration of the past ever witnessed such rapid prog- 

 ress in so many fields of knowledge or the develop- 

 ment of so many brand-new ideas in theoretical 

 science as have come to light in this age. 



SEVEN WONDERS OF THE MODERN WORLD 



Let me cite now another illustration of the re- 

 markable character of present-day achievements. 

 Every one has heard of the seven wonders of antiq- 

 uity, and most readers will recall that the pyramids
