A sweeping history of the electric light revolution and the birth of modern America The late nineteenth century was a period of explosive technological creativity, but more than any other invention, Thomas Edison’s incandescent light bulb marked the arrival of modernity, transforming its inventor into a mythic figure and avatar of an era. In The Age of Edison, award-winning author and historian Ernest Freeberg weaves a narrative that reaches from Coney Island and Broadway to the tiniest towns of rural America, tracing the progress of electric light through the reactions of everyone who saw it and capturing the wonder Edison’s invention inspired. It is a quintessentially American story of ingenuity, ambition, and possibility in which the greater forces of progress and change are made by one of our most humble and ubiquitous objects.

Many consider Thomas Edison the inventor of the light bulb, but this world-changing invention has a long history. Since the 19th century, many have worked to create and improve the light bulb. Starting from the light bulb’s early development all the way up to its modern uses, this informative title will fascinate anyone who wants to know about the invention that lights up the world!
How Many Light Bulbs Does It Take to Change the World? by Matt Ridley,Stephen Davies Pdf
Almost every schoolchild learns that Thomas Edison invented the light bulb. But did he? And if he hadn’t invented it, would we be still living in the dark? Acclaimed author Matt Ridley (The Rational Optimist, The Evolution of Everything) explains that at least 20 other people can lay claim to this breakthrough moment. Ridley argues that the light bulb emerged from the combined technologies and accumulated knowledge of the day – it was bound to emerge sooner or later. Based on his 2018 Hayek Memorial Lecture, Ridley contends that innovation – from invention through to development and commercialisation – is the most important unsolved problem in all of human society. We rely on it – but we do not fully understand it, we cannot predict it and we cannot direct it. In How Many Light Bulbs Does It Take to Change the World? Ridley examines the nature of innovation – and how people often fear its consequences. He dispels the myth that automation destroys jobs – and demonstrates how innovation leads to economic growth. And he argues that intellectual property rights, originally intended to encourage innovation, are now being used by big business to defend their monopolies. Ridley concludes that innovation is a mysterious and under-appreciated process that we discuss too rarely, hamper too much and value too little.

Dreamland: Adventures in the Strange Science of Sleep by David K. Randall Pdf
An engrossing examination of the science behind the little-known world of sleep. Like many of us, journalist David K. Randall never gave sleep much thought. That is, until he began sleepwalking. One midnight crash into a hallway wall sent him on an investigation into the strange science of sleep. In Dreamland, Randall explores the research that is investigating those dark hours that make up nearly a third of our lives. Taking readers from military battlefields to children’s bedrooms, Dreamland shows that sleep isn't as simple as it seems. Why did the results of one sleep study change the bookmakers’ odds for certain Monday Night Football games? Do women sleep differently than men? And if you happen to kill someone while you are sleepwalking, does that count as murder? This book is a tour of the often odd, sometimes disturbing, and always fascinating things that go on in the peculiar world of sleep. You’ll never look at your pillow the same way again.
The gripping history of electricity and how the fateful collision of Thomas Edison, Nikola Tesla, and George Westinghouse left the world utterly transformed. In the final decades of the nineteenth century, three brilliant and visionary titans of America’s Gilded Age—Thomas Edison, Nikola Tesla, and George Westinghouse—battled bitterly as each vied to create a vast and powerful electrical empire. In Empires of Light, historian Jill Jonnes portrays this extraordinary trio and their riveting and ruthless world of cutting-edge science, invention, intrigue, money, death, and hard-eyed Wall Street millionaires. At the heart of the story are Thomas Alva Edison, the nation’s most famous and folksy inventor, creator of the incandescent light bulb and mastermind of the world’s first direct current electrical light networks; the Serbian wizard of invention Nikola Tesla, elegant, highly eccentric, a dreamer who revolutionized the generation and delivery of electricity; and the charismatic George Westinghouse, Pittsburgh inventor and tough corporate entrepreneur, an industrial idealist who in the era of gaslight imagined a world powered by cheap and plentiful electricity and worked heart and soul to create it. Edison struggled to introduce his radical new direct current (DC) technology into the hurly-burly of New York City as Tesla and Westinghouse challenged his dominance with their alternating current (AC), thus setting the stage for one of the eeriest feuds in American corporate history, the War of the Electric Currents. The battlegrounds: Wall Street, the 1893 Chicago World’s Fair, Niagara Falls, and, finally, the death chamber—Jonnes takes us on the tense walk down a prison hallway and into the sunlit room where William Kemmler, convicted ax murderer, became the first man to die in the electric chair.
How electric light created new spaces that transformed the built environment and the perception of modern architecture. In this book, Sandy Isenstadt examines electric light as a form of architecture—as a new, uniquely modern kind of building material. Electric light was more than just a novel way of brightening a room or illuminating a streetscape; it brought with it new ways of perceiving and experiencing space itself. If modernity can be characterized by rapid, incessant change, and modernism as the creative response to such change, Isenstadt argues, then electricity—instantaneous, malleable, ubiquitous, evanescent—is modernity's medium. Isenstadt shows how the introduction of electric lighting at the end of the nineteenth century created new architectural spaces that altered and sometimes eclipsed previously existing spaces. He constructs an architectural history of these new spaces through five examples, ranging from the tangible miracle of the light switch to the immaterial and borderless gloom of the wartime blackout. He describes what it means when an ordinary person can play God by flipping a switch; when the roving cone of automobile headlights places driver and passenger at the vertex of a luminous cavity; when lighting in factories is seen to enhance productivity; when Times Square became an emblem of illuminated commercial speech; and when the absence of electric light in a blackout produced a new type of space. In this book, the first sustained examination of the spatial effects of electric lighting, Isenstadt reconceives modernism in architecture to account for the new perceptual conditions and visual habits that followed widespread electrification.
Examines the electric bulb, an invention at first ridiculed, distrusted, and feared, which ultimately led to new uses of electricity and transformed society.
Black Inventors Who Changed History by Debra D. Rich Pdf
Black Inventors Who Changed History 1800s–1900s By: Debra D. Rich African American scholar and historian Lerone Bennett Jr. once said, “If our children are to make history, they must first know their own history.” Deeply inspired by this sentiment, author Debra Rich set out to chronicle the lives of groundbreaking black inventors who have helped shape the world but who receive little credit or fame. With great talent and an unbreakable spirit, these African Americans overcame prejudice, poverty, violence, and hatred to create inventions we still use today. Finally, their stories must be told.
