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.

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.

Download or read book Creating the American Junkie written by Caroline Jean Acker and published by JHU Press. This book was released on 2006-01-05 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heroin was only one drug among many that worried Progressive Era anti-vice reformers, but by the mid-twentieth century, heroin addiction came to symbolize irredeemable deviance. Creating the American Junkie examines how psychiatrists and psychologists produced a construction of opiate addicts as deviants with inherently flawed personalities caught in the grip of a dependency from which few would ever escape. Their portrayal of the tough urban addict helped bolster the federal government's policy of drug prohibition and created a social context that made the life of the American heroin addict, or junkie, more, not less, precarious in the wake of Progressive Era reforms. Weaving together the accounts of addicts and researchers, Acker examines how the construction of addiction in the early twentieth century was strongly influenced by the professional concerns of psychiatrists seeking to increase their medical authority; by the disciplinary ambitions of pharmacologists to build a drug development infrastructure; and by the American Medical Association's campaign to reduce prescriptions of opiates and to absolve physicians in private practice from the necessity of treating difficult addicts as patients. In contrast, early sociological studies of heroin addicts formed a basis for criticizing the criminalization of addiction. By 1940, Acker concludes, a particular configuration of ideas about opiate addiction was firmly in place and remained essentially stable until the enormous demographic changes in drug use of the 1960s and 1970s prompted changes in the understanding of addiction—and in public policy.
