They Changed the World: Crick & Watson - The Discovery of DNA by Lewis Helfand Pdf
Since the dawn of civilization, we have searched for answers to what makes life possible, and in the mid-twentieth century we found them through the persistent efforts of James Watson and Francis Crick. Although the groundwork for the discovery had already been laid out, it was Watson and Crick's derivation of the three-dimensional, double-helical model for the structure of DNA that solved the final piece of the puzzle and won them the Nobel Prize in Physiology or Medicine in 1962. That is only a single moment of triumph, though, and the journey they took to get there was a long and arduous one. Find out how Crick and Watson beat their rivals to unlock the secrets of life itself as they unravelled the mystery behind DNA and changed not only science but the world we live in.
War of the Currents by Stephanie Sammartino McPherson Pdf
In the early 1880s, only a few wealthy people had electric lighting in their homes. Everyone else had use more dangerous lighting, such as gas lamps. Eager companies wanted to be the first to supply electricity to more Americans. The early providers would set the standards—and reap great profits. Inventor Thomas Edison already had a leading role in the industry: he had invented the first reliable electrical lightbulb. By 1882 his Edison Electric Light Company was distributing electricity using a system called direct current, or DC. But an inventor named Nikola Tesla challenged Edison. Tesla believed that an alternating current—or AC—system would be better. With an AC system, one power station could deliver electricity across many miles, compared to only about one mile for DC. Each inventor had his backers. Business tycoon George Westinghouse put his money behind Tesla and built AC power stations. Meanwhile, Edison and his DC backers said that AC could easily electrocute people. Edison believed this risk would sway public opinion toward DC power. The battle over which system would become standard became known as the War of the Currents. This exciting book tells the story of that war, the people who fought it, and the ways in which both kinds of electric power changed the world.
Thomas Alva Edison and Nikola Tesla by Samantha Green Pdf
For much of the world, turning on electricity is as easy as flipping a switch, but that wasn't always the case. At the end of the nineteenth century, two geniuses competed to change the world: Thomas Edison and Nikola Tesla. In the War of Currents, they fought to shape the world with their electrical systems. Without Edison and Tesla, we might not have the lightbulb, the radio, affordable electricity, and movies. This book examines the lives of these two inventors, their dizzying array of creations, and a professional rivalry that began the moment they met each other.
Conquering Everest: The Lives of Edmund Hillary and Tenzing Norgay by Lewis Helfand Pdf
Tenzing Norgay was the son of poor Tibetan immigrants living in Nepal. He longed to see the world but was told he could aspire to be little more than a servant. Edmund Hillary was a humble beekeeper from New Zealand, who spent his youth dreaming of adventures he could never hope to experience. And Everest was the ultimate adventure. The mountain's peak is the highest point on Earth, stretching beyond the clouds. So dangerous and challenging, Everest had never been successfully climbed and many had died trying. In 1953, Tenzing Norgay and Edmund Hillary joined a team of explorers determined to reach its top. Alone at the top of the world with their oxygen running low, they faced brutal elements and new dangers at every turn. And they were armed with little more than their courage, determination, and a belief in each other. But would that be enough to achieve the impossible, what no man had done before?
Nikola Tesla today is largely unknown and overlooked among the great scientists of the modern era. While Thomas Edison, the most famous inventor in American history, gets all the glory for discovering the light bulb. But it was his one-time assistant and life-long arch nemesis, Tesla, who made the breakthrough in alternating current electricity. Edison and Tesla carried on a bitter feud for years, but it was Tesla's AC generators that illuminated the 1893 World's Fair in Chicago under artificial light. Today all homes and electrical appliances run on Tesla's AC current. 120 years ago, they were billed as the 'Twin Wizards of Electricity', here Nigel Cawthorne chronicles the life and times of the two great men to help us finally decide just who really is the Electric King- Edison or Tesla?
Leonardo Da Vinci: The Renaissance Man by Dan Danko Pdf

Here, his talent blossomed and as fate would have it, he was soon employed by the rich and powerful Duke of Milan. Soon, Leonardo moved to the city of Rome, where some of the greatest artists of the time lived. This tale traces the fascinating life of one of the best and most famous artists that the world has ever seen.
While we all know that large-scale industrialization began in the eighteenth century, the Industrial Revolution truly began in Germany with Johannes Gutenberg and his printing press. His innovation made it possible to mass-produce books, which spread literacy and knowledge all across Europe. It was in the eighteenth century, however, that manual labor started being replaced by what we today know as machines. First in Europe came Thomas Newcomen and James Watt and the steam engine. Then came John Kay and his flying shuttle, which led to the development of the textile industry. Then, in the United States, there was Robert Fulton and his steamboat, and Eli Whitney and his cotton gin. Finally, it was Henry Ford whose mass-produced vehicles made cars affordable to all. The Industrial Revolution continues to this day as formerly less developed countries, especially in Asia, have taken to rapid industrialization to improve their economy. Lexile Reading Level 800L.

NEW YORK TIMES BESTSELLER • “A world of invention and skulduggery, populated by the likes of Edison, Westinghouse, and Tesla.”—Erik Larson “A model of superior historical fiction . . . an exciting, sometimes astonishing story.”—The Washington Post From Graham Moore, the Oscar-winning screenwriter of The Imitation Game and New York Times bestselling author of The Sherlockian, comes a thrilling novel—based on actual events—about the nature of genius, the cost of ambition, and the battle to electrify America. New York, 1888. Gas lamps still flicker in the city streets, but the miracle of electric light is in its infancy. The person who controls the means to turn night into day will make history—and a vast fortune. A young untested lawyer named Paul Cravath, fresh out of Columbia Law School, takes a case that seems impossible to win. Paul’s client, George Westinghouse, has been sued by Thomas Edison over a billion-dollar question: Who invented the light bulb and holds the right to power the country? The case affords Paul entry to the heady world of high society—the glittering parties in Gramercy Park mansions, and the more insidious dealings done behind closed doors. The task facing him is beyond daunting. Edison is a wily, dangerous opponent with vast resources at his disposal—private spies, newspapers in his pocket, and the backing of J. P. Morgan himself. Yet this unknown lawyer shares with his famous adversary a compulsion to win at all costs. How will he do it? In obsessive pursuit of victory, Paul crosses paths with Nikola Tesla, an eccentric, brilliant inventor who may hold the key to defeating Edison, and with Agnes Huntington, a beautiful opera singer who proves to be a flawless performer on stage and off. As Paul takes greater and greater risks, he’ll find that everyone in his path is playing their own game, and no one is quite who they seem. NAMED ONE OF THE BEST BOOKS OF THE YEAR BY THE WASHINGTON POST AND THE PHILADELPHIA INQUIRER “A satisfying romp . . . Takes place against a backdrop rich with period detail . . . Works wonderfully as an entertainment . . . As it charges forward, the novel leaves no dot unconnected.”—Noah Hawley, The New York Times Book Review
