Herbert Dingle 
Century of Science 1851-1951 [PDF ebook] 

First published in 1951 to coincide with the British Festival, this book explores the developments in science which had occurred since the Great Exhibition of 1851. Covering the full range of scientific development which had emerged in that time — from fundamental physics to evolution and genetics, and from geology to medical surgery — this accessible collection of essays charts with impressive comprehension and clarity the momentous changes which had occurred in the pursuit of science since the mid-nineteenth century, and ably demonstrates the appropriateness of citing the twentieth century as the advent of the scientific age. A Century of Science will appeal to those interested in the history of science, those wishing to ground their knowledge of specific scientific disciplines in a broader understanding of the subject, and also to the general reader who values scientific progress and the questions it continues to raise.
