The Great Match, and Other Matches is an unchanged, high-quality reprint of the original edition of 1877.Hansebooks is editor of the literature on different topic areas such as research and science, travel and expeditions, cooking and nutrition, medicine, and other genres. As a publisher we focus on the preservation of historical literature. Many works of historical writers and scientists are available today as antiques only. Hansebooks newly publishes these books and contributes to the preservation of literature which has become rare and historical knowledge for the future.

What is Electricity? - the International Scientific Series - Vol. 82 ist ein unveränderter, hochwertiger Nachdruck der Originalausgabe aus dem Jahr 1897.Hansebooks ist Herausgeber von Literatur zu unterschiedlichen Themengebieten wie Forschung und Wissenschaft, Reisen und Expeditionen, Kochen und Ernährung, Medizin und weiteren Genres. Der Schwerpunkt des Verlages liegt auf dem Erhalt historischer Literatur. Viele Werke historischer Schriftsteller und Wissenschaftler sind heute nur noch als Antiquitäten erhältlich. Hansebooks verlegt diese Bücher neu und trägt damit zum Erhalt selten gewordener Literatur und historischem Wissen auch für die Zukunft bei.

Not illustrated. 1922 edition. Excerpt: ... CHAPTER XIV THE PARTICLE OF THE ELECTRIC CURRENT TYNDALL'S treatise on the relations of heat to motion marked an epoch in physical science: we are now entering upon greatly enlarged views of motion. In the consideration of the theory of the electric nature of energy--the electromagnetic theory--we conceive of a universal ether by means of which the electrodynamic waves travel through space. This medium is supposed by some to be continuous, by others to have a grained structure. It is certainly easier to conceive of a grained structure than of continuous matter: water seems to be a type of continuity, but we know that it is made up of molecules or atoms of hydrogen and oxygen. Water is incompressible, the ether of space is also supposed to be incompressible. Waves of water travel just as the waves of energy traverse space: a cork on water moves up and down at right angles to the direction of propagation of a wave, the undulations of the electrodynamic waves in the ether are also at right angles to the direction of the waves. Some think in regarding the movement of waves in water that the ether may be composed of infinitely small particles which constitute an ocean. The fluid theories of electricity which prevailed in Franklin's time had the same idea of continuity that the present theory of ether has. We have freed ourselves from a belief in fluid theories and seem to advance to a theory of grained structure of the ether. We shall see in considering the new subject of photo-electricity the effeet of ultra-violet light upon electrical charges that grave doubts are rising in regard to the continuous nature of the ether. The electromagnetic waves are revealed in the release of chemical bonds and in the phenomena of photo-electricity. When an...
