  • Electromagnetism and the Metonymic Imagination

    Pennsylvania State University Press Electromagnetism and the Metonymic Imagination

    Out of stock

    Book SynopsisIllustrates how the discovery of electromagnetism in 1820 not only led to technological inventions, such as the dynamo and the telegraph, but also legitimized modes of reasoning that manifested a sharper ability to perceive how metonymic relations could reveal the order of things.Trade Review“A fascinating and convincing argument that treats the notion of magnetism in an original way. It will become indispensable reading for cultural historians who are interested in the connections between science and the broader literary or social culture in the eighteenth, nineteenth, and twentieth centuries.”—David Bell,author of Real Time: Accelerating Narrative from Balzac to Zola“With its uncluttered prose and careful explications of thorny debates and esoteric philosophies, Electromagnetism and the Metonymic Imagination brings precision to a sometimes fuzzy field of interdisciplinary inquiry. Literary scholars will learn much from this book’s cogent analyses, not only about the long history of magnetism, from the sixth-century Aetius of Amida to today’s Magnetic Resonance Imaging (MRI) technology, but also about how that history has been deeply intertwined with—and marked by—literary reconceptions of imaginative thought.”—Andrea Goulet Nineteenth-Century French Studies“Murphy contributes to ongoing studies on the “electric age” by convincingly demonstrating how electromagnetism drove conceptual and enduring changes in literary and scientific practices. Electromagnetic thinking, including the application of metonymic relations, revealed new ways of ordering and investigating the world. His comparative approach synthesizes electromagnetic analogies across discipline, genre, and national specificities.”—Kameron Sanzo The British Society for Literature and Science“By investigating the links between electricity and magnetism, Murphy uncovers forces that bind the natural and human sciences, literature and science, and analysis and creativity.”—Lindsey Grubbs Poe StudiesTable of ContentsAcknowledgmentsIntroduction1.

    Out of stock

    Book SynopsisAlthough there is a good deal of research concerning semiconductor impurities available, most publications on the subject are very specialized and very theoretical. Until now, the field lacked a text that described the current experimental data, applications, and theory concerning impurities in semiconductor physics. Impurities in Semiconductors: Solubility, Migration and Interactions explores the behavior of impurity atoms in semiconductors, integrating experimental data with theoretical interpretation. It presents the current literature on the state and behavior of impurities in semiconductors. The author explains the basic physics of hydrogen-like impurities to help you understand the properties imparted by these impurities. He also analyzes the macroscopic and microscopic mechanisms of the solubility, and migration of impurities and defects in the crystal lattice. In addition, the book presents a systematic analysis of different effects resulting from the interactions betweTable of ContentsThe Semiconductor-Impurity System. Impurity Behavior in Semiconductors.

    Book SynopsisThis second edition of the well-known work stresses important aspects of magnetic resonance theory that are of increasing importance to the research worker. Presents mathematical background and the basic prototype two-spin 1/2-1/2 Hamiltonian treatment as a building block to the more specialized subjects developed: higher spins and anistropies, applications to atomic spectra, crystal field theory, Mossbauer resonance, types of double resonance, and dynamic polarization. Specialized extensions are then discussed at length, with the advantage of showing clearly their relationships to the main body of magnetic resonance theory: ENDOR, ELDOR, polarization, spin labels, saturation transfer and fourier transform methods, and NMR imaging. Much of this material is treated by means of the uniform formalism based on the direct product matrix expansion technique.Table of ContentsMathematical and Quantum-Mechanical Background.
