Taschenbuch. Zustand: Neu. Neuware - The future of computing is here-and it will change everything. We stand at the threshold of the quantum age, where computers harness the bizarre properties of quantum mechanics to solve problems that would take classical computers longer than the age of the universe. From revolutionizing drug discovery to optimizing global supply chains, quantum computers promise to transform industries and accelerate scientific breakthroughs beyond our wildest imagination. But this technological revolution comes with unprecedented risks. The same quantum computers that could cure cancer and solve climate change also threaten to shatter the cryptographic security protecting our digital civilization. Every online transaction, private message, and state secret secured by current encryption could become vulnerable overnight. The Quantum Revolution takes you inside this technological transformation that governments and corporations are racing to control. You'll discover how quantum computers work, why tech giants and nations are investing billions in quantum research, and how this technology will reshape everything from healthcare and finance to national security and artificial intelligence. The quantum future isn't coming-it's already here. Tech companies offer quantum computing through the cloud, while intelligence agencies prepare for the collapse of current encryption methods. Whether quantum computers enhance or endanger our technological civilization depends on the choices we make today. The revolution has begun. Are you ready.…

Taschenbuch. Zustand: Neu. Neuware - Flip a switch, and light appears. Behind that simple act sits a machine most Americans have never consciously seen and could not name if asked: the power transformer. It is the device that made Thomas Edison's direct-current dream obsolete within a decade, the device that let a single power plant at Niagara Falls light cities two hundred miles away, and the device now sitting at the center of America's most urgent energy bottleneck. In The Machine That Moves Electricity, Douglas Donovan traces the transformer from Michael Faraday's induction ring and the 'War of the Currents' through the giant 400-ton units that had to be shipped by rail and barge to build the modern grid, into the factories struggling today to keep pace with a once-unthinkable surge in demand. Utilities that ordered transformers in 2021 are still waiting for delivery in 2026. Electrical steel, copper, and skilled labor have become as strategically important as the semiconductors that dominate the headlines-and just as scarce. Written in the same accessible, deeply researched style as Donovan's A History of the United States Electrical Grid and The Reliability Frontier, this book stands on its own as the definitive popular account of the machine that quietly makes modern life possible, while completing the trilogy's picture of an American grid straining to meet an electric future nobody fully planned for.…

Taschenbuch. Zustand: Neu. Neuware - Embark on humanity's greatest adventure-understanding our place in an infinite universe. From the moment our ancient ancestors first gazed at the night sky in wonder, we have sought to comprehend the cosmos that surrounds us. A Cosmic Journey: From the Big Bang to Black Holes takes readers on an extraordinary voyage through 13.8 billion years of cosmic evolution, revealing how the universe transformed from a hot, dense beginning into the magnificent tapestry of stars, galaxies, and exotic objects we observe today. Douglas Donovan masterfully guides readers through the revolutionary discoveries that shattered our Earth-centered view of reality and unveiled the true grandeur of the cosmos. Witness how Einstein's insights about space and time unlocked the secrets of stellar energy and black holes. Discover how the same physical laws governing our daily lives also power the nuclear furnaces of stars and drive the expansion of space itself. Explore the cosmic hierarchy that stretches from subatomic particles to galaxy clusters spanning billions of light-years. This engaging exploration reveals how astrophysicists work as cosmic detectives, extracting profound insights from the faintest signals reaching Earth across vast distances and eons of time. Each chapter illuminates the elegant connections between terrestrial physics and cosmic phenomena, showing how nuclear reactions in stellar cores create the elements essential for life, how gravitational forces sculpt the architecture of the universe, and how the marriage of space and time enables us to peer back toward the very moment of creation. Written for curious minds seeking to understand their cosmic heritage, \*A Cosmic Journey\* transforms complex astrophysical concepts into accessible insights without sacrificing scientific rigor. Whether you're fascinated by the violent deaths of massive stars, intrigued by the mysterious nature of dark matter and dark energy, or simply wondering how we fit into the grand cosmic story, this book provides the knowledge and perspective to appreciate humanity's most profound scientific achievement-understanding our universe. Prepare to see the cosmos, and your place within it, with entirely new eyes. The universe revealed through astrophysics proves far stranger and more magnificent than our ancestors could have imagined, yet it remains comprehensible through human reason and scientific investigation.…

Taschenbuch. Zustand: Neu. Neuware - It is midnight in Las Vegas, and a beam of light powerful enough to be seen from space is shooting straight up into the desert sky - drawing insects by the hundreds of thousands, and the bats that feed on them, into an ecosystem that exists for no reason other than that we built a light and pointed it upward. A continent away, an astronomer is waiting patiently for photons that have traveled for eleven billion years, hoping nothing gets in their way before they land. For nearly the whole of human history, the night sky was not a special occasion - it was the Milky Way overhead, thousands of stars, a shared inheritance that guided sailors, timed harvests, and filled every mythology on Earth. Today, a third of humanity, and four out of five people in North America, can no longer see it from home. \*The Last Dark Sky\* tells the story of how we got here - from whale-oil lamps and gaslit boulevards to Edison's bulb, the neon strip, and the Las Vegas beam that started it all - and then takes an unexpected turn skyward. Because just as artificial light finished conquering our own backyards, a new threat arrived from orbit: tens of thousands of satellites, streaking across telescope images and threatening the very darkness that billion-dollar observatories were built in remote deserts to protect. Blending history, astronomy, ecology, and hard-won optimism, this is the story of a species racing to see farther into the universe than ever before - while making it harder, with every passing year, to simply step outside and look up.The night sky was never really ours to keep. The only question this book leaves you with is whether we're willing to give any of it back.…
