During long winter nights, the light of the aurora borealis appears over the sparcely populated north. Little is known, however, about these dazzling displays of ghostly light and movement. The author discusses the history, mythology, and science behind auroras. Demonstrating the influence of the sun in the aurora's creation, he also compares the northern lights with phenomena such as lightning and rainbows. Lavishly illustrated with numerous color and black and white pictures, Aurora offers a comprehensive understanding of a mysterious dynamic that has fascinated and even alarmed northern communities through the ages.
Science, biography, and arctic exploration coverage in this extraordinary true story of the life and work of Norwegian scientist Kristian Birkeland, the troubled genius who solved the mysteries of one of nature’s most spectacular displays. Captivated by the otherworldly lights of the aurora borealis, Birkeland embarked on a lifelong quest to discover their cause. His pursuit took him to some of the most forbidding landscapes on earth, from the remote snowcapped mountains of Norway to the war-torn deserts of Africa. In the face of rebuke by the scientific establishment, sabotage by a jealous rival, and his own battles with depression and paranoia, Birkeland remained steadfast. Although ultimately vindicated, his theories were unheralded—and his hopes for the Nobel Prize scuttled—at the time of his suspicious death in 1917. The Northern Lights offers a brilliant account of the physics behind the aurora borealis and a rare look inside the mind of one of history's most visionary scientists.
Written in a light and friendly style, this lavishly illustrated book introduces the Sun and its physics, and describes all aspects of the Sun’s interaction with us on Earth. The second edition of this book updates the popular text by providing comprehensive accounts of the most recent discoveries made by five modern solar spacecraft during the past decade. It contains a number of images never before seen in print. Breakthrough observations with the underground Sudbury Neutrino Observatory are also included. The new edition further provides modern interpretations of ozone depletion and global warming.
The scientific knowledge of nanoscience and nanotechnology is regarded to be a modern sciencethat evolved after Feynman’s concept was formulated in the 1950s. However, Faraday and other scientists in the 19th century showed the science behind the small and its relation to optical properties. And it is now accepted that knowledge of using nanoparticles prevailed during the medieval period as well. This book takes the readers on a fascinating journey writing the history of nanotechnology based on the evidence of existence from the prehistoric period right up to the contemporary times. Nature utilized nanotechnology during the origin and expansion of the universe and especially in the evolution of living beings on our planet. Early civilizations in different parts of globe fabricated and used materials without having perception of their actual size. This unique historical view systematically evaluates the development of various applications of nanotechnology through the ages and the science behind it. Some of the issues covered include: • How old is nanotechnology? • Pre-historic evidence of knowledge of nanotechnology • Nanotechnology in ancient India • Ayurvedic Bhasma as nanomedicine • Mayan’s knowledge of nanotechnology • Nanotechnology during the Roman empire and medieval period • European knowledge in the 19th century • Modern and contemporary history of nanotechnology This book is compilation of existence of scientific knowledge even of the people who existed before there were schools, universities and organized teaching. The author has scoured literature dating back to Mayan … as well as historical observations A systematic evaluation of development of various applications of nanotechnology and the science behind it is presented in this book under following headings -How old is Nanotechnology -Pre-historic Evidence of Knowledge of Nanotechnology -Nanotechnology in Ancient India -Ayurvedic Bhasma as Nanomedicine, its use prevails even today -Mayan’s Knowledge of Nanotechnology -Nanotechnologists Flourished During Roman Empire and medieval period -European Nano knowledge That Led to Faraday Understands of Gold Nanoparticles -Contemporary History of Nanotechnology

Science, Technology and Magic in The Witcher by Kristine Larsen Pdf
As Andrzej Sapkowski was fleshing out his character Geralt of Rivia for a writing contest, he did not set out to write a science textbook--or even a work of science fiction. However, the world that Sapkowski created in his series The Witcher resulted in a valuable reflection of real-world developments in science and technology. As the Witcher books have been published across decades, the sorcery in the series acts as an extension of the modern science it grows alongside. This book explores the fascinating entanglement of science and magic that lies at the heart of Sapkowski's novel series and its widely popular video game and television adaptations. This is the first English-language book-length treatment of magic and science in the Witcher universe. These are examined through the lenses of politics, religion, history and mythology. Sapkowski's richly detailed universe investigates the sociology of science and ponders some of the most pressing modern technological issues, such as genetic engineering, climate change, weapons of mass destruction, sexism, speciesism and environmentalism. Chapters explore the unsettling realization that the greatest monsters are frequently human, and their heinous acts often involve the unwitting hand of science.
Eighteen Hundred and Froze to Death by John V H Dippel Pdf
Almost 200 years ago the Northeast endured a dramatic, devastating series of cold spells, destroying crops, forcing thousand to migrate west, and causing many to wonder if their assumptions about a world governed by a beneficial Providence were valid. The so-called "year without a summer" also exposed weaknesses in political and theological authorities, spurring a trend toward scientific inquiry and greater democracy. An endangered New England agriculture gave impetus to that region's manufacturing sector. The alarming threat to existence in that part of the country (as well as most of Western Europe) thus helped usher in the modern era. This book is written with the parallels between 1816 and our current "climate change" in mind: it introduces informed non-specialists to the myriad of social, psychological, political, demographic, and economic consequences which can be brought about by abrupt change. A major meteorological event profoundly affected our nation’s development in 1816. This book shows how this weather phenomenon acted as an accelerator of trends which were just emerging in the early 19th-century - toward greater democracy and the spread of information; settlement of the Western frontier; use of the scientific method to investigate and understand natural phenomena; questioning of long-held religious beliefs as a result of increased knowledge; and industrialization as the means to expand the scope and wealth of the United States. Like all my books, America’s First Climate Crisis is written in an accessible, engaging style, using anecdotes and thumbnail sketches to evoke the mood and important personalities of the day. While thoroughly researched, the book avoids the pitfall of academic writing by appealing to the curiosity of intelligent readers who may be put off by uninspired or technical language. The book is organized around various consequences of the disastrous harvests of 1816: after outlining the nature and scope of this calamity, I describe how it brought about a massive exodus to the Ohio Valley and shift in political and economic might to that region; how it undermined the once-unquestioned authority of New England’s Federalist establishment; how it gave greater credence to scientific explanations for weather events and disasters; how it compelled New England merchants to abandon their opposition to manufacturing; and how it helped create a modern awareness of humanity’s place in the universe.
Dayside and Polar Cap Aurora by Per Even Sandholt,H.C. Carlson,A. Egeland Pdf
The auroral emissions in the upper atmosphere of the polar regions of the Earth are evidence of the capture of energetic particles from the Sun, streaming by the Earth as the solar wind. These auroral emissions, then, are a window to outer space, and can provide us with valuable information about electrodynamic coupling processes between the solar wind and the Earth's ionosphere and upper atmosphere. Studying the physics of these phenomena extends our understanding of our plasma universe. Ground-based remote-sensing techniques, able to monitor continuously the variations in the signatures of aurorae, in combination with in-situ satellite and rocket measurements, promise to advance dramatically our understanding of the physical processes taking place at the interface of the atmospheres of the Earth and the Sun. Decoding their complexity brings us closer to reliable prediction of communication environments, especially at high latitudes. This understanding, in turn, will help us resolve problems of communication and navigation across polar regions.

Monstrous births, rains of blood, apparitions of battles in the sky - people in early modern England found all of these events to carry important religious and political meanings. In An age of wonders, available in paperback for the first time, William E. Burns explores the process by which these events became religiously and politically insignificant in the Restoration period. The story involves the establishment of early modern science, the shift from 'enthusiastic' to reasonable religion, and the fierce political combat between the Whigs and the Tories.This historical study is based on close readings of a variety of primary sources, both print and manuscript. Burns claims that prodigies lost their religious meaning and became subjects of scientific enquiry as a result of political struggles, first by the supporters of the restored monarchy and the Church of England against Protestant dissenters, and then by the Whig defenders of the Revolution of 1688 against the Tories and the Jacobites.By integrating religious and political history with the history of science, An age of wonders will be of great use to those working in the field of early modern history.

The book includes a comprehensive collection of data on industrial nanoparticle creation and the characterization of the nanoscale products of these processes. The authors describe the effects of these nanoscale structures on human health and discuss prospective implementations for detection and characterization of nanoparticles in the environment. They recommend, utilizing the most up-to-date understanding of nanotechnology, methods for limiting the negative effects of these products on the environment and human health through manipulation, sorting, and filtration.
"A treasure of a book."—David McCullough The harrowing story of a pathbreaking naval expedition that set out to map the entire Pacific Ocean, dwarfing Lewis and Clark with its discoveries, from the New York Times bestselling author of Valiant Ambition and In the Hurricane's Eye. A New York Times Notable Book America's first frontier was not the West; it was the sea, and no one writes more eloquently about that watery wilderness than Nathaniel Philbrick. In his bestselling In the Heart of the Sea Philbrick probed the nightmarish dangers of the vast Pacific. Now, in an epic sea adventure, he writes about one of the most ambitious voyages of discovery the Western world has ever seen—the U.S. Exploring Expedition of 1838–1842. On a scale that dwarfed the journey of Lewis and Clark, six magnificent sailing vessels and a crew of hundreds set out to map the entire Pacific Ocean and ended up naming the newly discovered continent of Antarctica, collecting what would become the basis of the Smithsonian Institution. Combining spellbinding human drama and meticulous research, Philbrick reconstructs the dark saga of the voyage to show why, instead of being celebrated and revered as that of Lewis and Clark, it has—until now—been relegated to a footnote in the national memory. Winner of the Theodore and Franklin D. Roosevelt Naval History Prize
