Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Radio-Activity of Uranium The researches of M. Henri Becquerel have shown that compounds of uranium possess the property now called radio-activity; that is, rays emitted by them affect a sensitive photographic plate through bodies usually considered opaque to light; they discharge an electrometer when brought near it; and they are deflected by a magnet. These rays are now called "Becquerel rays," or "uranic rays." 2. On the discovery by M. and Mdme. Curie of polonium and radium, bodies of enormous radio-active powers, it was suggested that uranium might possibly owe its power to the presence of a small quantity of one of these bodies. But in a paper published in the Revue Generale des Sciences for January, 1899, Mdme. Curie says: - "This does not appear probable, for if such were the case different samples of uranium compounds would have very different radio-activities, but in the course of a number of experiments made with various samples of metallic uranium, as well as with oxides and salts from various sources, I have never found any marked difference between the relative activities of the same compound." In another paper the same author says that "the property of emitting rays... which act on photographic plates is a specific property of uranium and thorium." "The physical condition of the metal seems to be of an altogether secondary importance." "Uranium and thorium alone are practically active." 3. When the discovery of radium was announced, and it was said to have "to all appearance the properties of almost pure barium," it occurred to me that radium might be found in detectable quantities in some barium minerals were search made among them from different localities. Accordingly specimens of the following minerals were put on sensitive plates, a sheet of black paper separating them from the sensitive surface. As it was probable that the radio-active substance would be present, if at all, in very minute quantities, the sensitive plate was exposed to their influence for forty-eight hours.

Such properties are' action on photographic plates, power of producing beautiful scintillations and coloured phosphorescence with zinc blende and certain other minerals, power to bring about many chemical actions, continual and relatively considerable evolution of heat, and various beneficial therapeutic actions which have resulted from its application in medicine. We, must, therefore, study these radiations with exactness, and must consider their mode of produc tion. The substances producing them are known.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Radioactive Transformations In the year 1883 a legacy of eighty thousand dollars was left to the President and Fellows of Yale College in the city of New Haven, to be held in trust, as a gift from her children, in memory of their beloved and honored mother Mrs. Hepsa Ely Silliman. On this foundation Yale College was requested and directed to establish an annual course of lectures designed to illustrate the presence and providence, the wisdom and goodness of God, as manifested in the natural and moral world. These were to be designated as the Mrs. Hepsa Ely Silliman Memorial Lectures. It was the belief of the testator that any orderly presentation of the facts of nature or history contributed to the end of this foundation more effectively than any attempt to emphasize the elements of doctrine or of creed; and he therefore provided that lectures on dogmatic or polemical theology should be excluded from the scope of this foundation, and that the subjects should be selected rather from the domains of natural science and history, giving special prominence to astronomy, chemistry, geology, and anatomy. It was further directed that each annual course should be made the basis of a volume to form part of a series constituting a memorial to Mrs. Silliman. The memorial fund came into the possession of the Corporation of Yale University in the year 1902; and the present volume constitutes the third of the series of memorial lectures.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Radio-Activity An examination of natural substances, in order to see if they gave out dark radiations similar to X rays, led to the discovery of the radio-active bodies which possess the property of spontaneously emitting radiations, invisible to the eye, but readily detected by their action on photographic plates and their power of discharging electrified bodies. A detailed study of the radio-active bodies has led to the discovery of many new and surprising phenomena which have thrown much light, not only on the nature of the radiations themselves, but also on the processes occurring in those substances. Notwithstanding the complex nature of the phenomena, the know ledge of the subject has advanced with great rapidity, and a large amount of experimental data has now been accumulated.

This book was released on 2018-02-08 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Radioactivity and Geology, an Account of the Influence of Radioactive Energy on Terrestrial History To these laboriously detailed observations upon the rocks the more generalized ones upon the radioactivity of the ocean have to be added. In its waters and its sediments we are presented with the age-long accumulation of materials arising from the denudation of the primary rocks. Thus the oceanic radioactivity testifies to the world-wide presence of uranium in those surface materials which, throughout the whole of geological time, contributed substances to the seas. When, finally, we compare the results on impoverished detrital sediments with those on the igneous rocks, we find their joint evidence in harmony with that yielded by the ocean.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Wonders of Radium: Explained in a Popular Manner This brief discourse is intended to place before you, in a popular manner, the wonders of Radium, which have revolutionised modern Science, and indeed, hold out the promise of giving to mankind new powers, undreamt of.a few years ago. It is necessary to omit all calculations, technical data, and various delicate experiments, from which the facts here given were obtained, and many of these facts, moreover, cannot be accepted as perfectly accurate, since it is desired to avoid a considerable amount of technicality which must otherwise be introduced, if the subject is to be treated from a purely scientific standpoint. My object is to explain to the mind which is not technical, the wonders of radio-active matter, and the results possible from the discovery. Consequently, the simplest language and the simplest methods must be employed. I have taken my facts in a large measure from the papers and works of Professors Rutherford, Strutt, Soddy, Makover, Sir William Ramsay, Sir J. J. Thomson, the Curies, Becquerel, and others. It was Becquerel who first investigated the radio-active nature of Uranium; and later the Curies, when examining Uranium ore for radio-active properties, found some minerals far more active than would have been expected, and naturally concluded that there must be something more in the material than the Uranium they were examining. The result was the discovery of a highly radio active substance called Polonium, which is in fact a substance produced from Radium during its disintegration. Later, the Curies found the element known as Radium, which Madame Curie was recently able to obtain in a metallic state, but which could not be kept in that state owing to its rapid combination with other elements. In fact, Radium is generally used in the form of a bro mide, sulphate, or other combination. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
