Free-roaming killer drones stalk the battlespace searching for natural pursuits. Human warring parties are programmed to consider no discomfort. Highpower microwave beams detonate munitions, jam communications, and prepare dinner inner organs.

Is this imaginative and prescient of destiny warfare attainable, or maybe inevitable? during this well timed new e-book, Everett Carl Dolman examines the connection among technology and warfare. traditionally, technology has performed an incredible position in finishing wars – consider the half performed via tanks in breaching trench conflict within the First global conflict, or atom bombs in hastening the japanese give up within the moment international conflict – yet up to now this has purely elevated the risk and destructiveness of destiny conflicts. may perhaps technology ever create the con-ditions of an everlasting peace, both by means of making wars most unlikely to win, or so terrible that nobody may ever struggle? eventually, Dolman argues that technology can't, by itself, finish conflict with out additionally finishing what it skill to be human.

If provided the chance—by cloak, spell, or superpower—to be invisible, who wouldn’t are looking to provide it a attempt? we're interested in the belief of stealthy voyeurism and the facility to hide our personal acts, yet as fascinating because it could seem, invisibility can also be risky. it isn't simply an optical phenomenon, yet a filled with moral questions. As esteemed technological know-how author Philip Ball finds during this ebook, the tale of invisibility isn't rather a lot a question of the way it'd be completed yet of why we'd like it and what we might do with it.

during this energetic examine a undying suggestion, Ball presents the 1st finished historical past of our fascination with the unseen. This sweeping narrative strikes from medieval spell books to the newest nanotechnology, from fairy stories to telecommunications, from camouflage to ghosts to the sunrise of nuclear physics and the invention of darkish power.  Along the best way, Invisible tells little-known tales approximately medieval monks who blamed their misdeeds on spirits; the Cock Lane ghost, which intrigued either Samuel Johnson and Charles Dickens; the makes an attempt via Victorian scientist William Crookes to discover forces utilizing tiny windmills; novelist Edward Bulwer-Lytton’s trust that he was once unseen whilst in his dressing costume; and army efforts to enlist magicians to conceal tanks and ships in the course of WWII.  Bringing in such voices as Plato and Shakespeare, Ball offers not just a systematic heritage yet a cultural one—showing how our simultaneous wish for and suspicion of the invisible has fueled invention and the mind's eye for centuries.

during this strange and smart booklet, Ball indicates that our fantasies approximately being unseen—and seeing the unseen—reveal extraordinary truths approximately who we are.

His goal—to hinder each affliction that generally attacked children—was unimaginable. yet Maurice Hilleman got here close.

Maurice Hilleman is the daddy of contemporary vaccines. leader between his accomplishments are 9 vaccines that essentially each baby will get, rendering previously lethal diseases—including mumps, rubella, and measles—nearly forgotten. writer Paul A. Offit's wealthy and vigorous narrative info Hilleman's examine and studies because the foundation for a bigger exploration of the advance of vaccines, protecting 200 years of scientific heritage and touring around the globe within the approach. The heritage of vaccines inevitably brings with it a cautionary message, as they've got come lower than attack from these insisting they do extra damage than strong. Paul Offit basically and compellingly rebuts those arguments, and, via demonstrating how a lot the paintings of Hilleman and others has won for humanity, exhibits us how a lot we need to lose.

In 1650, Archbishop James Ussher of Armagh joined the long-running theological debate at the age of the earth via famously asserting that production had happened on October 23, 4004 B.C. even though generally challenged through the Enlightenment, this trust in a six-thousand-year-old planet was once merely laid to leisure in the course of a revolution of discovery within the past due eighteenth and early 19th centuries. during this fairly short interval, geologists reconstructed the immensely lengthy heritage of the earth-and the fairly fresh arrival of human lifestyles. Highlighting a discovery that noticeably altered present perceptions of a human's position within the universe up to the theories of Copernicus, Darwin, and Freud did, Bursting the boundaries of Time is a herculean attempt by way of one of many world's premiere specialists at the historical past of geology and paleontology to caricature this historicization of the wildlife within the age of revolution.

Addressing this highbrow revolution for the 1st time, Rudwick examines the tips and practices of earth scientists in the course of the Western international to teach how the tale of what we now name "deep time" was once pieced jointly. He explores who was once answerable for the invention of the earth's heritage, refutes the concept that of a rift among technology and faith in courting the earth, and info how the examine of the background of the earth helped outline a brand new department of technology known as geology. Rooting his research in an in depth learn of fundamental assets, Rudwick emphasizes the lasting value of box- and museum-based study of the eighteenth and 19th centuries.

Bursting the bounds of Time, the fruits of greater than 3 a long time of analysis, is the 1st designated account of this enormous section within the heritage of science.

A well known cognitive neuroscientist?s interesting and hugely informative account of the way the mind acquires reading

How can a number of black marks on a white web page evoke a whole universe of sounds and meanings? during this riveting research, Stanislas Dehaene presents an available account of the mind circuitry of examining and explores what he calls the ?reading paradox?: Our cortex is the made from hundreds of thousands of years of evolution in a global with no writing, so how did it adapt to acknowledge phrases? Reading within the Brain describes pioneering examine on how we approach language, revealing the hidden good judgment of spelling and the lifestyles of robust subconscious mechanisms for interpreting phrases of any dimension, case, or font.

Dehaene?s examine will fascinate not just readers attracted to technological know-how and tradition, but additionally educators concerned about debates on how we discover ways to learn, and who strive against with pathologies comparable to dyslexia. Like Steven Pinker, Dehaene argues that the brain isn't really a clean slate: Writing structures throughout all cultures depend on an identical mind circuits, and interpreting is barely attainable insofar because it matches in the limits of a primate mind. surroundings state of the art technology within the context of cultural debate, Reading within the Brain is an remarkable advisor to a uniquely human ability.
