  • For thirty years or more the expressions “Correlation of the Physical Forces” and “The Conservation of Energy” have been common, yet few persons have taken the necessary pains to think out clearly what mechanical changes take place when one form of energy is transformed into another. Since Tyndall gave us his book called Heat as a Mode of Motion neither lecturers nor text-books have attempted to explain how all phenomena are the necessary outcome of the various forms of motion.

  • "Show me a man who makes no mistakes, and I will show you a man who has done nothing."—LIEBIG. In this little volume the author gives but his own personal opinions upon the subjects discussed, and although the sentiments are expressed with an assurance born of conviction, yet he claims not infallibility. He has ever been unable to accept the usual explanations of the great physical forces; and the inadequacies of mooted theories have impelled him to efforts for more philosophical interpretations.

  • I CAN not more appropriately introduce the Cosmos than by presenting a brief sketch of the life of its illustrious author.* While the name of Alexander von Humboldt is familiar to every one, few, perhaps, are aware of the peculiar circumstances of his scientific career and of the extent of his labors in almost every department of physical knowledge. He was born on the 14th of September, 1769, and is, therefore, now in his 80th year.

  • The Einstein Theory of Relativity A Concise Statement by Prof. H.A. Lorentz of the University of Leyden Copyright, 1920page 5 Note Whether it is true or not that not more than twelve persons in all the world are able to understand Einstein's Theory, it is nevertheless a fact that there is a constant demand for information about this much-debated topic of relativity. The books published on the subject are so technical that only a person trained in pure physics and higher mathematics is able to fully understand them.

  • For many decades, scientists have been trying to devise a single unified theory to explain all known physical phenomena, but a model that appears to unite the seemingly incompatible String Theory and Standard Model has existed for 100 years. It described baryons, mesons, quarks and preons over 50 years before conventional science. It stated that matter is composed of strings 80 years before string theory. It described the existence of anti-matter 30 years before conventional science. It described the Higgs field over 50 years before Peter Higgs.

  • The author in this work endeavours to solve the greatest scientific problem that has puzzled scientists for the past two hundred years. The question has arisen over and over again, since the discovery of universal gravitation by Sir Isaac Newton, as to what is the physical cause of the attraction of gravitation. “Action at a distance” has long ceased to be recognized as a possible phenomenon, although up to the present, the medium and method of gravitational attraction have not yet been discovered.

  • One peculiarity of this age is the sudden acquisition of much physical knowledge. There is scarcely a department of science or art which is the same, or at all the same, as it was fifty years ago. A new world of inventions—of railways and of telegraphs— has grown up around us which we cannot help seeing; a new world of ideas is in the air and affects us, though we do not see it. A full estimate of these effects would require a great book, and I am sure I could not write it; but I think I may...

  • A work on electricity needs little recommendation to stimulate the interest of the general reader. Electricity in its manifold applications is so large a factor in the comfort and convenience of our daily life, so essential to the industrial organization which embraces every dweller in a civilized land, so important in .the development and extension of civilization itself, that a knowledge of its principles and the means through which they are directed to the service of mankind should be a part of the mental equipment of everyone who pretends to education in its truest sense.

  • Many more women are active today compared to when the first studies of activity in America were conducted. However, as a group, girls and women are still less active than boys and men. Some of this difference in activity between males and females can be explained by the historical disparity in opportunities for females. Since 1972, when Title IX was implemented, more females have become involved in organized sport. We have yet to discover the effects of this increased participation on lifetime activity among females....

  • The aim in the preparation of this treatise on the human body has been, first, to set forth in a teachable manner the actual science of physiology; and second, to present the facts of hygiene largely as applied physiology. The view is held that "right living" consists in the harmonious adjustment of one's habits to the nature and plan of the body, and that the best preparation for such living is a correct understanding of the physical self. It is further held that the emphasizing of physiology augments in no .small degree the educative value of the subject, greater opportunity...

  • Agesilaus, king of Sparta, when asked what things boys should learn, replied, “Those which they will practise when they become men.” As health requires the observance of the laws inherent to the different organs of the human system, so not only boys, but girls, should acquire a knowledge of the laws of their organization. If sound morality depends upon the inculcation of correct principles in youth, equally so does a sound physical system depend on a correct physical education during the same period of life.

  • A non-mathematical presentation has necessary limitations; and the reader who wishes to learn how certain exact results follow from Einstein's, or even Newton's, law of gravitation is bound to seek the reasons in a mathematical treatise. But this limitation of range is perhaps less serious than the limitation of intrinsic truth. There is a relativity of truth, as there is a relativity of space.|

  • Moreover, in contrast to the dominant thinking of our age, which is materialistic, King's philosophy is spiritual and religious. Indeed, the ideas in this book are so profoundly different from the commonly accepted ideas of our times that they will come as a shock to many readers. One purpose of this introduction is to prepare the reader for such a shock. I have said that the dominant thinking of our age is materialistic, and by that I mean also physical. Let me illustrate this broad statement with reference to the subject of fears alone.
