It was not Robert Oppenheimer who built the bomb--it was engineers, chemists and young physicists in their twenties, many not yet having earned a degree. The first atomic bomb was originally conceived as a backup device, a weapon not then currently achievable. The remote Trinity Site--the birthplace of the bomb--was used as a test range for U.S. bombers before the first nuclear device was secretly detonated. After the blast, locals speculated that the flash and rumble were caused by colliding B-29s, while Manhattan Project officials nervously measured high levels of offsite radiation. Drawing on original documents, many recently declassified, the author sheds new light on a pivotal moment in history--now approaching its 75th anniversary--told from the point of view of the men who inaugurated the Atomic Age in the New Mexico desert.
Maine to Greenland is a testament to one of the world's great geographic regions: the Maritime Far Northeast. For more than three decades, William W. Fitzhugh and Wilfred E. Richard have explored the Northeast’s Atlantic corridor and its fascinating history, habitat, and culture. The authors’ powerful personal essays and Richard’s stunning photography transport readers to this vibrant region, joining Smithsonian archaeological expeditions and trekking in vast and amazing terrain. Following Fitzhugh and Richard’s travels north—from Maine to the Canadian Maritimes, Newfoundland and northern Quebec, then to Labrador, Baffin and Ellesmere islands, and Greenland—we view incredible landscapes, uncover human history, and meet luminous personalities along the way. Fully illustrated with 350 full-color photographs, Maine to Greenland is the first in-depth treatment of the Northeast Atlantic corridor and essential for armchair travelers, locals, tourists, or anyone who has journeyed there. Today green technology, climate change, and the opening of the Arctic Ocean have transformed the Maritime Far Northeast from an icy frontier into a global resource zone and an increasingly integrated international crossroads. In our rapidly converging world, we have much to learn from the Maritime Far Northeast and how its variety of cultures have adapted to rather than changed their environments during the past ten thousand years. Maine to Greenland is not only a complete account of the region’s unique culture and environment, but also a timely reminder that amidst the very real consequences of climate change, the inhabitants of the Maritime Far Northeast can show us grounded and sustainable ways of living.
This book explores accounts in the Sagas of Icelanders of encounters with foreign peoples, both abroad and in Iceland, who are portrayed according to stereotypes which vary depending on their origins. Notably, inhabitants of the places identified in the sagas as Írland, Skotland and Vínland are portrayed as being less civilized than the Icelanders themselves. This book explores the ways in which the Íslendingasögur emphasize this relative barbarity through descriptions of diet, material culture, style of warfare and character. These characteristics are discussed in relation to parallel descriptions of Icelandic characters and lifestyle within the Íslendingasögur, and also in the context of a tradition in contemporary European literature, which portrayed the Icelanders themselves as barbaric. Comparisons are made with descriptions of barbarians in classical Roman texts, primarily Sallust, but also Caesar and Tacitus, showing striking similarities between Roman and Icelandic ideas about barbarians.
This textbook offers clear explanations of optical spectroscopic phenomena and shows how spectroscopic techniques are used in modern molecular and cellular biophysics and biochemistry. The topics covered include electronic and vibrational absorption, fluorescence, resonance energy transfer, exciton interactions, circular dichroism, coherence and dephasing, ultrafast pump-probe and photon-echo spectroscopy, single-molecule and fluorescence-correlation spectroscopy, Raman scattering, and multiphoton absorption. This revised and updated edition provides expanded discussions of quantum optics, metal-ligand charge-transfer transitions, entropy changes during photoexcitation, electron transfer from excited molecules, normal-mode calculations, vibrational Stark effects, studies of fast processes by resonance energy transfer in single molecules, and two-dimensional electronic and vibrational spectroscopy. The explanations are sufficiently thorough and detailed to be useful for researchers and graduate students and advanced undergraduates in chemistry, biochemistry and biophysics. They are based on time-dependent quantum mechanics, but are developed from first principles with a clarity that makes them accessible to readers with little prior training in this field. Extra topics and highlights are featured in special boxes throughout the text. The author also provides helpful exercises for each chapter.
