Benjamin Franklin is well known to most of us, yet his fundamental and wide-ranging contributions to science are still not adequately understood. Until now he has usually been incorrectly regarded as a practical inventor and tinkerer rather than a scientific thinker. He was elected to membership in the elite Royal Society because his experiments and original theory of electricity had made a science of that new subject. His popular fame came from his two lightning experiments—the sentry-box experiment and the later and more famous experiment of the kite—which confirmed his theoretical speculations about the identity of electricity and provided a basis for the practical invention of the lightning rod. Franklin advanced the eighteenth-century understanding of all phenomena of electricity and provided a model for experimental science in general.

I. Bernard Cohen, an eminent historian of science and the principal elucidator of Franklin’s scientific work, examines his activities in fields ranging from heat to astronomy. He provides masterful accounts of the theoretical background of Franklin’s science (especially his study of Newton), the experiments he performed, and their influence throughout Europe as well as the United States. Cohen emphasizes that Franklin’s political and diplomatic career cannot be understood apart from his scientific activities, which established his reputation and brought him into contact with leaders of British and European society. A supplement by Samuel J. Edgerton considers Franklin’s attempts to improve the design of heating stoves, another practical application that arose from theoretical interests.

This volume will be valuable to all readers wanting to learn more about Franklin and to gain a deeper appreciation of the development of science in America.

Lightning research is an interdisciplinary subject where several branches of engineering and physics converge. Lightning Electromagnetics is a book that caters for the needs of both physicists and engineers. It provides: The physicist with information on how to simulate: the charge generation in thunderclouds, different discharge processes in air that ultimately lead to a lightning flash, and the mechanism through which energetic radiation in the form of X-rays and Gamma rays are produced by lightning flashes; The power engineer with several numerical tools to study the interaction of lightning flashes with power transmission and distribution systems; The telecommunication engineer with numerical procedures with which to calculate the electromagnetic fields generated by lightning flashes and their interactions with overhead and underground telecommunication systems; The electromagnetic specialist with the basic theory necessary to simulate the propagation of lightning electromagnetic fields over the surface of the Earth; The atmospheric scientist with numerical procedures to quantify interactions between lightning flashes and the Earth's atmosphere, including the production of NOx by lightning flashes occurring in the atmosphere. This book also contains a chapter on the stimulation of visual phenomena in humans by electromagnetic fields of lightning flashes, which is essential reading for those who are interested in ball lightning.

This updated and expanded new edition of Cooray's classic text provides the reader with a thorough background in almost every aspect of lightning and its impact on electrical and electronic equipment. The contents range from basic discharge processes in air through transient electromagnetic field generation and interaction with overhead lines and underground cables, to lightning protection and testing techniques. New to this edition are discussions of high-speed video recordings of lightning; rocket-and-wire triggered lightning experiments; tower initiated lightning discharges; upper atmospheric electrical discharges; attachment of lightning flashes to grounded structures; energetic radiation from thunderstorms and lightning; global lightning nitrogen oxides production; and lightning and global temperature change.

This unique book provides the reader with a thorough background in almost every aspect of lightning and its impact on electrical and electronic equipment. The contents range from basic discharge processes in air through transient electromagnetic field generation and interaction with overhead lines and underground cables, to lightning protection and testing techniques. This book is of value to anyone designing, installing or commissioning equipment which needs to be secured against lightning strikes, as well as being a sound introduction to research students working in the field.

Thunder and lightning have been seen from time immemorial as God’s instruments of punishment. Until the invention of the lightning rod by Benjamin Franklin in 1752. In Lightning in the Age of Benjamin Franklin. Facts and Fictions in Science, Religion, and Art Jan Wim Buisman shows how the Enlightenment and Romanticism have changed our scientific, religious and artistic image of natural violence forever. In the eighteenth century, thunderstorms are experienced less and less as a threat and more and more as something extraordinary. The image of God and the image of nature changed radically. The religion of enlightened people, for example, was more determined by joy than by fear. And nature was almost experienced as a girlfriend. That had significant consequences because those who no longer had to be afraid of the thunderstorm could play with it without hesitation. That’s what poets, painters and musicians did to their heart’s content. Never before the beauty of the storm was depicted as much in the western culture as during the transition from the Enlightenment to Romanticism.

An intersection of jazz and the written word: poems to be experienced and felt

Sweetgum & Lightning lets us into an extraordinary poetic universe, shaped by a vernacular rooted in the language of self, one’s origins, and music. In poems that are deeply sensual in nature, Rodney Terich Leonard considers gender and sexuality, art, poverty, and community. Imagery expands through unexpected lexical associations and rumination on the function of language; words take on new meaning and specificity, and the music of language becomes tantamount to the denotations of words themselves. Through extensive webs of connotation, Leonard’s narratives achieve a sense of accuracy and intimacy. The nuanced lens of these poems is indicative of the honesty of expression at work in the collection—one that affirms the essentiality of perception to living and memory.
