Book excerpt: Excerpt from Memoirs of the National Academy of Science, 1927, Vol. 19 From the various considerations already adduced it Will be quite clear that no general philosophy of petrogenesis should be based upon a study of a portion of the 1gneous recks alone, however complete-it might be' in regard to geological, petrographical, and physico-che'mical circumstances; and therefore, since no study of the intermediate and acid types of normal and alkaline 1gneous rocks has been made by the writer comparable in detail with those upon basic igneous rocks here given, it must be recognized that the generalizations which follow are derived perhaps too exclusively from the' study of basic rocks. If, however, they are found to be an adequate statement of the modes of occurrence of such rocks, they may then be combined with the results of s1m11ar studies upon the other types of rocks into a general petrogenetic theory. While no invariable rules for mode of occurrence of basic intrusive rocks seem yet dis coverable, there emerge from the studies which follow the conception of several modes of occur 'rence, so frequently represented that they' seem to result from fundamental principles of petrogenesis, while the exceptions to these are especially worthy of study, .s1nce in all probability they will throw most light upon the nature of the controlling conditions and the relationships to one another of apparently distinct modes of occurrence.

Book excerpt: Excerpt from Bulletin of the National Research Council, Vol. 4: September, 1922, to December, 1922, Inclusive When we adopt the conventional language of Euclidean geometry a gravitational field of Einstein's type is, in our opinion, comparable with a material medium with electric and magnetic polarizations. There is, however, the important distinction that in a gravitational field the coefficients a satisfy certain gravitational equations which are characteristic of Einstein's theory and to obtain a material medium whose properties are associated with a quadratic difi'erential form having coefficients of the right type we may have to introduce polariza tions which travel with velocity c. Fields arising from polarization of this type will be studied in Section 10. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Scientific Memoirs, Vol. 2 During the course of the past few weeks I have met with a series of phenomena in certain experiments on the subcutaneous injection of choleraic comma-bacilli into the bodies of guinea-pigs which appear to be sufficiently remarkable to merit special record. I propose, therefore, in the present paper to give a detailed account of these experiments and their results, along with a few brief notes regarding their apparent significance. I. - Source of the material employed in the experiments. The commas employed in all the experiments belonged to a series of cultivations originally derived from a case of cholera which was admitted into the Medical College Hospital on the 21st January 1886. A portion of a fresh evacuation was sent to me for examination on that day. It consisted of a brownish-grey, alkaline, watery fluid, and an abundant sediment of gelatinous, somewhat pinkish flocculi. The examination of fresh preparations, made immediately on the arrival of the material, showed that it was crowded with schizomycete organisms of various forms. Commas were only present in very small numbers and constituted a very inconspicuous feature as compared with other forms. In spite of this, however, a plate cultivation yielded what was practically a pure crop of commatous colonies. These were present in innumerable numbers, and the only other form of colonies recognisable were two or three consisting of a very large kind of micrococcus which was present as a conspicuous feature in the original material. This plate afforded the starting-point for a series of successive pure tube cultivations of the commas which were employed in the experiments.

Download or read book Probing the Sky with Radio Waves written by Chen-Pang Yeang and published by University of Chicago Press. This book was released on 2013-07-02 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: By the late nineteenth century, engineers and experimental scientists generally knew how radio waves behaved, and by 1901 scientists were able to manipulate them to transmit messages across long distances. What no one could understand, however, was why radio waves followed the curvature of the Earth. Theorists puzzled over this for nearly twenty years before physicists confirmed the zig-zag theory, a solution that led to the discovery of a layer in the Earth’s upper atmosphere that bounces radio waves earthward—the ionosphere. In Probing the Sky with Radio Waves, Chen-Pang Yeang documents this monumental discovery and the advances in radio ionospheric propagation research that occurred in its aftermath. Yeang illustrates how the discovery of the ionosphere transformed atmospheric science from what had been primarily an observational endeavor into an experimental science. It also gave researchers a host of new theories, experiments, and instruments with which to better understand the atmosphere’s constitution, the origin of atmospheric electricity, and how the sun and geomagnetism shape the Earth’s atmosphere. This book will be warmly welcomed by scholars of astronomy, atmospheric science, geoscience, military and institutional history, and the history and philosophy of science and technology, as well as by radio amateurs and electrical engineers interested in historical perspectives on their craft.
