Par Mike Massimino. 2016
NEW YORK TIMES BESTSELLER • NASA astronaut Mike Massimino shares incredible true stories from space—a rare, wonderful world where science…
meets the most thrilling adventure. &“Mike is a spaceman through and through; he tells how hard work can take you out of this world.&”—Bill Nye the Science Guy Have you ever wondered what it would be like to find yourself strapped to a giant rocket that&’s about to go from zero to 17,500 miles per hour? Or to look back on Earth from outer space and see the surprisingly precise line between day and night? Or to stand in front of the Hubble Space Telescope, wondering if the emergency repair you&’re about to make will inadvertently ruin humankind&’s chance to unlock the universe&’s secrets? Mike Massimino has been there, and in Spaceman he puts you inside the suit, with all the zip and buoyancy of life in microgravity.Massimino&’s childhood space dreams were born the day Neil Armstrong set foot on the moon. Growing up in a working-class Long Island family, he catapulted himself to Columbia and then MIT, only to flunk his first doctoral exam and be rejected three times by NASA before making it through the final round of astronaut selection.Taking us through the surreal wonder and beauty of his first spacewalk, the tragedy of losing friends in the Columbia shuttle accident, and the development of his enduring love for the Hubble Telescope—which he and his fellow astronauts were tasked with saving on his final mission—Massimino has written an ode to never giving up, revealing just what having &“the right stuff&” really means.Before Darwin . . . before Lewis and Clark . . . there was Alexander von Humboldt. Explorer. Naturalist. All-around…
genius. Lost hero of science. In his time, Alexander von Humboldt (1769–1859) was world-famous. Why? He led one of the first major scientific expeditions into the South American rain forest and another into the wilds of Siberia. Carrying fragile instruments, he navigated perilous rapids and climbed the volcano of Tenerife. He observed animals, plants, and cultures that no one in Europe had ever dreamed of, and his books about them inspired a whole generation of scientists—including Charles Darwin. But before he did any of that, he was a little boy who was curious about everything (especially bugs)! The Incredible yet True Adventures of Alexander von Humboldt will whisk you away to another time and place. Meet the young man who, defying his mother’s wishes, became a daring explorer-scientist—and follow along as he makes his amazing discoveries. Lavish illustrations bring Humboldt’s untamed world to life. See nature through the eyes of a great early scientist. Wonder awaits!Bigger and Better, Updated and Expanded We live in a golden age of paleontological discovery—on average, we find one new…
dinosaur species per week. The most fascinating among them take their place in this updated edition of Dinosaurs—The Grand Tour; from Aardonyx, a lumbering beast that formed a link between two- and four-legged dinosaurs, to Zuniceratops, who boasted a deadly pair of horns. Here, you’ll find everything worth knowing about every dinosaur worth knowing—more than 300 in all, including: Amphibious Halszkaraptor looks like no other dinosaur we’ve found—with a head and body the size of a duck’s, sharp claws . . . and a swanlike neck. Longer than a blue whale and three times taller than a giraffe, Patagotitan is a newly discovered contender for “biggest dinosaur ever.” The speedy little feathered predator Stenonychosaurus was an anatomical marvel, with retractable claws, asymmetrical ears for advanced hearing, incredible night vision, and a huge brain. Oviraptor—whose name means “egg thief “—doesn’t deserve its bad rap. This specimen from 1923 is now proven to have been sitting by its own eggs—not stealing another’s. Sinornithosaurus prove that dinosaurs shed their skin the same way that humans do, rather than sloughing it off all at once like a snake. At-a-glance sidebars put each dinosaur’s diet, size, and location at your fingertips. Stories of harrowing expeditions conjure the thrills of history’s most famous dinosaur hunters. Highlights from recent research reveal what’s new in paleontology today, including scientists’ evolving idea of what dinosaurs actually looked like. (Hint: They were more colorful—and feathery!—than we ever thought before.) And illustrations on virtually every page bring these prehistoric creatures to life in all their glory.The Electric War: Edison, Tesla, Westinghouse, and the Race to Light the World

called electricity promised to shine new light on a rousing nation. Inventive and ambitious minds were hard at work. Soon that spark was fanned, and a fiery war was under way to be the first to light—and run—the world with electricity. Thomas Alva Edison, the inventor of direct current (DC), engaged in a brutal battle with Nikola Tesla and George Westinghouse, the inventors of alternating current (AC). There would be no ties in this race—only a winner and a loser. The prize: a nationwide monopoly in electric current. Brimming with action, suspense, and rich historical and biographical information about these brilliant inventors, here is the rousing account of one of the world’s defining scientific competitions.
