This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it. This work was reproduced from the original artifact, and remains as true to the original work as possible. Therefore, you will see the original copyright references, library stamps (as most of these works have been housed in our most important libraries around the world), and other notations in the work.This w...

Excerpt from The GyroscopeThe theory of rotary motion is not simple, nor is it yet complete. Not all inventors have understood the reason for their devices, and not all mathematicians have had a clear conception of the theory, as evidenced by the un necessary complication oi their treatments.Attempts have been made to explain gyroscopic action without mathematics, or at least without the Calculus. It is hardly necessary to say that all such at...

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve ...

Excerpt from Thermics and Thermo-Dynamics of the BodyThe writer, for his own satisfaction, has made certain observa tions regarding the thermal constants of animal tissues, but since proper facilities were lacking, they can be considered scarcely more than surmises. In dealing with the problems shortly to be taken up it will be necessary to have some idea in regard to these constants, and the following determinations will serve to fix our idea...

Excerpt from The Mechanics of ElectricityThe general consensus of opinion at present is that electricity is something. Lodge writes, Electricity may possibly be a form of matter - it is not a form of energy. We have nowhere asserted that electricity and the ether are identical. If they are, we are bound to admit that the ether, though ¿uid in the sense of enabling masses to move freely through it, has a certain amount of rigidity for enormousl...

This is a reproduction of a book published before 1923. This book may have occasional imperfections such as missing or blurred pages, poor pictures, errant marks, etc. that were either part of the original artifact, or were introduced by the scanning process. We believe this work is culturally important, and despite the imperfections, have elected to bring it back into print as part of our continuing commitment to the preservation of printed w...

Excerpt from The Mechanics of Electricity When asked what electricity is, physicists a few years ago would reply, "We do not know, " and the inquirer was made to feel that he had asked a foolish question. To Maxwell, electricity itself seems to have been rather an abstraction, and he occupied himself chiefly with its effects, or the strains it produces in dielectrics. To the ultra-Maxwellians who declare that "there is no such thing as electr...

Excerpt from Thermics and Thermo-Dynamics of the Body We shall now attempt to write our physiological equation in the language of mathematics and afterwards to translate it. We have seen that for a warm-blooded animal the sum of the heats ex pended must equal the sum of the heats produced, for that is the condition of life. We shall endeavor first to tabulate the sources of heat in the body and measure these amounts as far as is possible. In ...
