Authoritative account written for the general reader.

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.

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.

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.

Publisher description

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

This book examines British scientific and antiquarian travels in the "North," circa 1790–1830. British perceptions, representations and imaginings of the North are considered part of late eighteenth- and early nineteenth-century processes of British self-fashioning as a Northern nation, and key in unifying the expanding North Atlantic empire.
