How do ideas become accepted by the scientific community? How and why do scientists choose among empirically equivalent theories? In this pathbreaking book translated from the Italian, Marcello Pera addresses these questions by exploring the politics, rhetoric, scientific practices, and metaphysical assumptions that entered into the famous Galvani-Volta controversy of the late eighteenth century. This lively debate erupted when two scientists, each examining the muscle contractions of a dissected frog in contact with metal, came up with opposing but experimentally valid explanations of the phenomenon. Luigi Galvani, a doctor and physiologist, believed that he had discovered animal electricity (electrical body fluid existing naturally in a state of disequilibrium), while the physicist Alessandro Volta attributed the contractions to ordinary physical electricity. Beginning with the electrical concepts understood by scientists in the 1790s, Pera traces the careers of Galvani and Volta and explains their laboratory procedures. He shows that their controversy derived from two basic, irreducible interpretations of the proper nature of a common domain: Galvani saw the frog phenomenon as the work of biological organs, Volta as that of a physical apparatus. The initial preference for Volta's theory, maintains Pera, depended not on clear-cut methodological rules, but on a dialectical dispute for which the renowned physicist was better equipped, partly because he shared the dominant metaphysical views of his time. Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These paperback editions preserve the original texts of these important books while presenting them in durable paperback editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

ARCHIVE COpy DO NOT REMOVE The public in industrialized countries shows a mounting concern about biological effects of electrical and magnetic fields. As a result, experimental studies on this subject are being published in increasing numbers throughout the world. Prof. H. L. Konig, of the Technical University of Munich, West Germany, a leading expert and pioneer in this field, has written an authoritative text in a lucid style which makes the material also accessible to lay readers. The book describes the effects of natural as well as artificial electromagnetic energies covering the en­ tire measurable frequency range from the highest frequencies, x-rays, through microwaves, radio waves, and finally extremely low frequency (ELF) waves. Cit­ ing the evidence from scientific studies in various countries, Konig also appraises the biologic effects of microwaves and high tension power lines, which have become controversial issues in recent years. Other contributions to the book have been made by Prof. Albert P. Krueger, University of California, Berkeley, on air ionization effects and by the mete­ orologist Walter Sonning on biometeorology, documenting the influence of atmo­ spheric electrical currents on health and disease. Moreover, the late Dr. Siegnot Lang, a former coworker of Dr. Konig, has contributed to this book.

In the first edition of Bioelectricity, Plonsey and Barr provided an introduction to electrophysiology following a quantitative approach. In this second edition they address new discoveries in the field of ion channels. The text is an introduction to electrophysiology utilizing a quantitative approach. It describes the principles of electrical fields, using basic principles from science and engineering while taking the biological applications into consideration. The book thus provides an introduction to the quantitative description of underlying electrophysiology with illustrative application to cardiac electrophysiology and functional electrical stimulation. The book can be used as a bridge to more advanced texts, particularly those that stress a quantitative approach.
