164 HAS SCIENCE DISCOVERED GOD? 



the earth and with the cosmologist's nebular hypothesis 

 of the making of worlds, and how every order of 

 facts — even the story of the Mind itself — became new 

 in a new light. 



So far then our first proposition : which amounts to 

 this, that from time to time the advance of science has 

 given mankind a new world, as may be illustrated by 

 thinking of what we owe to Copernicus, Newton, 

 Lavoisier, Joule, and Darwin. The newness may be 

 a fresh orientation, as in the change from geocentric 

 to heliocentric, and from fixity to flux of species; or a 

 new orderliness, such as was formulated in the Law 

 of Gravitation; or a new unity, such as that revealed 

 in the modern theory of the chemical elements, which 

 differ from one another in the numbers, arrangements, 

 and movements of their component electrons and 

 protons; or in the discovery of new chains of causes, 

 such as the establishment of stellar systems from 

 nebulae, the origin of planets from a sun, the emerg- 

 ence of new kinds of living creatures from simpler 

 ancestors, and the correlation of "the secret motions 

 of things," as Bacon phrased it, to yield a resultant 

 visible activity. 



One of the most impressive of all scientific diagrams 

 is that which shows in measured proportion all the 

 known electromagnetic vibrations, or "ether-waves," 

 from those of huge wave-lengths, used in broadcast- 

 ing, to those of very short wave-lengths, used in radio- 

 therapy. If we count the various rays included in 

 humanly-visible light as one octave, there are sixty-one 

 other octaves in the long gamut, — from gamma rays 

 to ultra-violet light, and from heat rays to Hertzian,
