Book Description
Excerpt from Journal of the Society of Telegraph Engineers, 1874, Vol. 3: Including Original Communications on Telegraphy and Electrical Science We owe to Gauss and iveber the first great practical realization in abstract science of a system of absolute measurement; but their principles did' not extend rapidly even in the domains of abstract science where their theory was well understood, because the urgent need for its practical application was not felt. When accurate measurement in any definite unit first became prevalent was when it was required by the electric telegraph. The pioneers of science in electric telegraphy, many of whom, happily for us, still work for science and for the electric telegraph, laid down - among various perfectly definite subjects for measurement - a unit of electric resistance - that most primary one of the different things to be measured respecting electricity. I need not remind any of you of the history of electric units of resistance, or of the labours of the Committee of the British Association to bring that system of measurement into harmony with the theoretical definitions of Gauss and Weber. The benefits conferred by introducing a system of definite measurement into the working of the electric telegraph are due not solely - perhaps not even in chief - to the application of Gauss's system, but to the introduction of very accurate and definite standards of resistance and means of reproducing those standards should the originals be lost. The benefit of putting the practical standards into relation with the science of Gauss and Weber has been set forth in the successive reports of the Committee of the British Association on electric measurement, and is well known, I believe, to most of the members of the Society of Telegraph Engineers. But what I wish to say now is that theoretical science has gained great reflected benefit from the introduction of accurate measure ment of resistance into practical telegraphy.

Book Description
Excerpt from Journal of the Society of Telegraph Engineers, 1880, Vol. 9: Including Original Communications on Telegraphy and Electrical Science The definition of force shows us that whatever changes or tends to change the motion of matter (or of the molecules of which it is composed), by altering either its direction or its magnitude, is a form of force. Thus gravity is a form of force, for it attraom all matter to the centre of the earth, and it is measured by the rate per second at which a body acquires a velocity in this direction when falling freely at a given spot. Heat is a form of force, for it throws the molecules of matter into violent vibration, or it increases the velocity of their motion in straight lines, which thus becomes the measure of its heat or its temperature. Light is a form of force, for it is produced by the undulation of the molecules of matter, and it is transmitted by the undulations of that medium called Ether, which fills all space. No man has seen or can see a molecule, nor have we any objective idea of what force really is. When we attempt to reach beyond these definitions, we tread upon the threshold of the holy of holies, on whose confines only are we permitted to dwell, and into which we are not yet allowed to enter. Hitherto shalt thou come but no further, and here shall thy proud waves he stayed. Let us, therefore, be content with precise definitions and clear mental conceptions, speculative though they be, of matter inert and of matter in motion. The ultimo finale of the scientific man is theory. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
