This historic book may have numerous typos, missing text or index. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. 1922. Not illustrated. 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 electrical current arise...

This is a romantic novel involving the love story of a US naval officer, the commander of a Navy destroyer, and a beautiful Dutch girl, the daughter of a Dutch attache in Manila. It takes place during the initial months of the Second World War in the Far East, and the final demise of the US Asiatic Fleet. It begins in the Philippines and continues in the Dutch East Indies (now, Indonesia). The story alternates between the love affair and the officer's naval duties during the Japanese invasion and conquest of the Philippines and the Dutch East Indies. Their love affair is complicated by the ongoing war and the efforts of the girl's parents to stop it. Instead, the parents want their daughter to marry a close family friend. The tempo is dictated by the slow but steady advance of the Japanese military through the Philippines and the Indonesian islands, and the struggle of the lovers to continue their romance despite all the difficulties.
