J. Arthur Thomson 
Revival: Modern Science (1929) [EPUB ebook] 

The aim of this book is to give a general idea of the way in which Modern Science looks out on the world. By selecting a few salient illustrations, it seeks to show how the various sciences are disclosing the Order of Nature. It is hoped that it may be of service to the able minded reader who wishes an introduction of an informal type to the chief scientific problems of today. The book is meant to be suggestive as well as informative; and two characteristic features may be noted, for they are deliberate: the illustrations of scientific progress that have been selected are taken from all the great orders of facts — from astronomy to anthropology; and they deal not with easy things, but with the big problems that matter most.
