MIRACLES OF SCIENCE 



INTRODUCTION 



WE often hear it said that the age of miracles is 

 past. This is a mistake. The age of miracles 

 is the twentieth century. But the miracles that are 

 now being performed are being done in accordance 

 with verifiable even though recondite laws of Na- 

 ture, and in the name of Science. 



For example, consider the feat of weighing and 

 measuring not merely our world but worlds that lie 

 so remote from us in the far places of the universe 

 that the light coming from them though compassing 

 space at the rate of 186,000 miles a second requires 

 a score of years to reach us. The astronomer not 

 only weighs and measures these distant worlds, but 

 he even tests their chemical composition almost as 

 definitely as if he held some of their substance in his 

 hand. And the chemicals that he tests are located so 

 many billions of miles away that the mere figures 

 that record their distance seem meaningless. 



Surely this seems miraculous. It would be unbe- 

 lievable if we did not know it to be true. 



At the other end of the scale the physicist investi- 

 gates the infinitely little. He makes visible with his
