WHY WRITTEN Fairies, fays, genii, sprites, etc., were once supposed to be helpful to some favored men. The stories about these imaginary beings have always had a fascinating interest. The most famous of these stories were told at Bagdad in the eleventh century, and were called The Arabian Nights' Entertainment. Then men were said to use all sorts of obedient powers, sorceries, tricks, and genii to aid them in ... more...
Applied Eugenics
by
INTRODUCTION The Great War has caused a vast destruction of the sounder portion of the belligerent peoples and it is certain that in the next generation the progeny of their weaker members will constitute a much larger proportion of the whole than would have been the case if the War had not occurred. Owing to this immeasurable calamity that has befallen the white race, the question of eugenics has ceased to ... more...

Aspects Of Recent Science
by
ASPECTS OF RECENT SCIENCE STUDENTS of the classics will recall that the old Roman historians were accustomed to detail the events of the remote past in what they were pleased to call annals, and to elaborate contemporary events into so-called histories. Actuated perhaps by the same motives, though with no conscious thought of imitation, I have been led to conclude this history of the development of natural ... more...

I. THE PHLOGISTON THEORY IN CHEMISTRY The development of the science of chemistry from the "science" of alchemy is a striking example of the complete revolution in the attitude of observers in the field of science. As has been pointed out in a preceding chapter, the alchemist, having a preconceived idea of how things should be, made all his experiments to prove his preconceived theory; while the chemist ... more...

I. THE SUCCESSORS OF NEWTON IN ASTRONOMY HEVELIUS AND HALLEY STRANGELY enough, the decade immediately following Newton was one of comparative barrenness in scientific progress, the early years of the eighteenth century not being as productive of great astronomers as the later years of the seventeenth, or, for that matter, as the later years of the eighteenth century itself. Several of the prominent ... more...

V. GALILEO AND THE NEW PHYSICS After Galileo had felt the strong hand of the Inquisition, in 1632, he was careful to confine his researches, or at least his publications, to topics that seemed free from theological implications. In doing so he reverted to the field of his earliest studies—namely, the field of mechanics; and the Dialoghi delle Nuove Scienze, which he finished in 1636, and which was ... more...

I. PREHISTORIC SCIENCE To speak of a prehistoric science may seem like a contradiction of terms. The word prehistoric seems to imply barbarism, while science, clearly enough, seems the outgrowth of civilization; but rightly considered, there is no contradiction. For, on the one hand, man had ceased to be a barbarian long before the beginning of what we call the historical period; and, on the other hand, ... more...

Huxley, Thomas Henry

Huxley, Thomas Henry
Scientific writer, son of an assistant master in a public school, was born at Ealing. From childhood he was an insatiable reader. In his 13th year he became a medical apprentice, and in 1842 entered Charing Cross Hospital. Thereafter he was for a few months surgeon on board the Victory at Haslar, and was then appointed surgeon on H.M.S. Rattlesnake, which was sent to make surveys at Torres Strait. While in this position he made numerous observations, which he communicated to the Linn?an Society. In 1851 he became a Fellow of the Royal Society, and in 1854 Prof. of Natural History at the School of Mines. Henceforth his life was a very full one, divided between ...
The most obvious and the most distinctive features of the History of Civilisation, during the last fifty years, is the wonderful increase of industrial production by the application of machinery, the improvement of old technical processes and the invention of new ones, accompanied by an even more remarkable development of old and new means of locomotion and intercommunication. By this rapid and vast ... more...
