In 1837 a comprehensive discussion of lightning appeared in the Annual of the French Bureau des Longitudes with a section on ball lightning which provided for the first time a readily available source in the scientific literature of the basic properties of this curious natural phenomenon. The author, Francois Arago, was the dominant influence in the French Academy of Sciences in the nineteenth century, having become a member of that august body at the age of twenty-three. His attention alone doubtless served at that time to establish the validity of scientific interest in the problem. In addition his discussion covered some of the major questions associated with ball lightning in a nota bly clear-sighted, effective style. Later reconsideration of the same questions often provided no significant improvement over Arago's discussion. There followed a dauntless band of varying but always small number who attempted to account for an apparently simple natural occurrence, a ball of fire usually seen in thunderstorms, with the best knowledge that advancing science could provide. All attempts to deal with this phenomenon were in variably frustrated. The characteristics of ball lightning could be readily cataloged, but they firmly resisted both experimental reproduction and theo retical explanation. One may say that to this day there is no explanation accepted by a large number of scientists. Several investigators of great ability and considerable accomplishment in different fields of science, including Faraday, Kelvin, and Arrhenius, took note of the problem.

Ball lightning is an enigma. These luminous objects that appear occasionally during thunderstorms and can reach several meters in diameter have been a mystery to science for about 200 years. Despite several thousands of reported observations, their nature is still unknown. In this book, well documented cases of ball lightning are described and used to unravel some aspects of this mysterious form of atmospheric electricity. Throughout the book, the author discusses the various facets of the problem in an accessible but rigorous style, delivering a readable and informative text that will captivate the curious reader. He finally reaches the surprising conclusion that the solution to this puzzle may have been hidden in plain sight for many years. A foreword by Earle Williams, leading lightning researcher at MIT, introduces the book.

Down comes a deluge of sonorous hail, Or prone-descending rain. Wide-rent, the clouds Pour a whole flood, and yet, its flame unquenched, Th’unconquerable lightning struggles through. Ragged and fierce, or in red whirling balls, And fires the mountains with redoubled rage. Black from the stroke, above, the smould’ring pine Stands a sad shattered trunk; and, stretched below, A lifeless group the blasted cattle lie. James Thompson, “The Seasons” (1727) have been investigating ball lightning for more than two decades. I published a ball lightning report in Nature in 1976 that received worldwide publicity and I consequently many people wrote to me with accounts of their own experiences. Within a very short time, I had accumulated about 200 firsthand accounts, and the file has continued to grow steadily since then. Several things impressed me. Few of those who wrote to me had any detailed foreknowledge of ball lightning at the time of their observation. Nonetheless, once reports of other phenomena such as St. Elmo’s fire had been eliminated, the remaining descriptions were remarkably consistent. Furthermore, nearly all who contacted me were keen to have an explanation of what they had seen and seemed entirely sincere.

From the New York Times bestselling author of the Three-Body Trilogy, Cixin Liu's Ball Lightning is the story of what happens when the beauty of scientific inquiry runs up against the drive to harness new discoveries with no consideration of their possible consequences. When Chen’s parents are incinerated before his eyes by a blast of ball lightning, he devotes his life to cracking the secret of this mysterious natural phenomenon. His search takes him to stormy mountaintops, an experimental military weapons lab, and an old Soviet science station. The more he learns, the more he comes to realize that ball lightning is just the tip of an entirely new frontier. While Chen’s quest for answers gives purpose to his lonely life, it also pits him against soldiers and scientists with motives of their own: a beautiful army major with an obsession with dangerous weaponry, and a physicist who has no place for ethical considerations in his single-minded pursuit of knowledge.

The purpose of this monograph is to review the known physical aspects of two unusual forms of atmospheric luminous phenomena, to deduce their characteristics and properties, and to promote efforts to improve their understanding. These two forms, called ball lightning and bead lightning, have visual images that differ from the linear image associated with normallightning. The terms "balliightning" and "bead lightning" are used to denote atmospheric luminous forms which are occasionally observed and have the geometrie shape suggested by their name. Vet, it is possible that neither phenomenon may in fact be a form of lightning in the sense of a continuous electrical discharge. Bead lightning has been described as the residue of a cloud-to cloud or cloud-to-ground lightning stroke and has the appearance of aseries of luminous balls separated by dark regions, thus resembling astring of pearls, and remains visible for about one second. Ball lightning has been described as a single luminous globe appearing ne ar the ground after a lightning stroke and also remaining visible for about one second. Both phenomena remain visible far longer than normal lightning flashes.

While the natural world is often described as organic, it is in fact structured to the very molecule, replete with patterned order that can be decoded with basic mathematical algorithms and principles. In a nautilus shell one can see logarithmic spirals, and the Golden Ratio can be seen in the seed head of the sunflower plant. These patterns and shapes have inspired artists, writers, designers, and musicians for thousands of years. "Patterns in Nature: Why the Natural World Looks the Way It Does" illuminates the amazing diversity of pattern in the natural world and takes readers on a visual tour of some of the world s most incredible natural wonders. Featuring awe-inspiring galleries of nature s most ingenious designs, "Patterns in Nature" is a synergy of art and science that will fascinate artists, nature lovers, and mathematicians alike."

From the winner of the 2017 John W. Campbell Award for Best New Writer, Ada Palmer's 2017 Compton Crook Award-winning political science fiction, Too Like the Lightning, ventures into a human future of extraordinary originality Mycroft Canner is a convict. For his crimes he is required, as is the custom of the 25th century, to wander the world being as useful as he can to all he meets. Carlyle Foster is a sensayer--a spiritual counselor in a world that has outlawed the public practice of religion, but which also knows that the inner lives of humans cannot be wished away. The world into which Mycroft and Carlyle have been born is as strange to our 21st-century eyes as ours would be to a native of the 1500s. It is a hard-won utopia built on technologically-generated abundance, and also on complex and mandatory systems of labelling all public writing and speech. What seem to us normal gender distinctions are now distinctly taboo in most social situations. And most of the world's population is affiliated with globe-girdling clans of the like-minded, whose endless economic and cultural competition is carefully managed by central planners of inestimable subtlety. To us it seems like a mad combination of heaven and hell. To them, it seems like normal life. And in this world, Mycroft and Carlyle have stumbled on the wild card that may destablize the system: the boy Bridger, who can effortlessly make his wishes come true. Who can, it would seem, bring inanimate objects to life... Terra Ignota 1. Too Like the Lightning 2. Seven Surrenders 3.
