Whir. Buzz.Not so long ago, math problems had to be solved with pencil and paper, mail delivered by postman, and files were stored in paper folders and metal cabinets. But three women, Betty Snyder, Jean Jennings, and Kay McNulty knew there could be a better way. During World War II, people hoped ENIAC (Electronic Numerical Integrator and Computer), one of the earliest computers, could help with the war effort. With little guidance, no instructions, and barely any access to the machine itself, Betty, Jean, and Kay used mathematics, electrical engineering, logic, and common sense to command a computer as large as a room and create the modern world. The machine was like Betty, requiring outside-the-box thinking, like Jean, persistent and consistent, and like Kay, no mistakes, every answer perfect. Today computers are all around us, performing every conceivable task, thanks, in large part, to Betty, Jean, and Kay's pioneering work. Instructions Not Included is their story.This fascinating chapter in history is brought to life with vivid prose by Tami Lewis Brown and Debbie Loren Dunn and with striking illustrations by Chelsea Beck. Detailed back matter including historical photos provides a closer look.

    Sachiko's family home was about half a mile from where the atomic bomb fell on August 9, 1945. Her family experienced devastating loss. When they returned to the rubble where their home once stood, her father miraculously found their serving bowl fully intact. This delicate, green, leaf-shaped bowl--which once held their daily meals--now holds memories of the past and serves as a vessel of hope, peace, and new traditions for Sachiko and the surviving members of her family.

    She reveals them to be curious, clever connoisseurs of their world, technologically inventive and ecologically adaptable. Above all, they were successful survivors for more than 300,000 years, during times of massive climatic upheaval.At a time when our species has never faced greater threats, we’re obsessed with what makes us special. But, much of what defines us was also in Neanderthals, and their DNA is still inside us. Planning, co-operation, altruism, craftsmanship, aesthetic sense, imagination... perhaps even a desire for transcendence beyond mortality.It is only by understanding them, that we can truly understand ourselves.

    Radiometric dating of nearby rocks indicated the skeleton, classified as Ardipithecus ramidus, was 4.4 million years old, more than a million years older than "Lucy," then the oldest known human ancestor. The findings challenged many assumptions about human evolution--how we started walking upright, how we evolved our nimble hands, and, most significantly, whether we were descended from an ancestor that resembled today's chimpanzee--and repudiated a half-century of paleoanthropological orthodoxy.Fossil Men is the first full-length exploration of Ardi, the fossil men who found her, and her impact on what we know about the origins of the human species. It is a scientific detective story played out in anatomy and the natural history of the human body. Kermit Pattison brings into focus a cast of eccentric, obsessive scientists, including one of the world's greatest fossil hunters, Tim White--an exacting and unforgiving fossil hunter whose virtuoso skills in the field were matched only by his propensity for making enemies; Gen Suwa, a Japanese savant who sometimes didn't bother going home at night to devote more hours to science; Owen Lovejoy, a onetime creationist-turned-paleoanthropologist; Berhane Asfaw, who survived imprisonment and torture to become Ethiopia's most senior paleoanthropologist and who fought for African scientists to gain equal footing in the study of human origins; and the Leakeys, for decades the most famous family in paloanthropology.An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa and a nation caught in a brutal civil war, to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must read for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.

    Its walls are rich with stories. Its walls are rich with stories. In this book we hear myriad of those voices. First we follow a young person today. Her great-great-grandmother entered America through Ellis Island. As this young girl walks the halls of the famous site, she wonders about the past, the people, and their hopes, dreams and challenges. Here, too, is the voice of Sera, an Armenian girl from the early 1900s. Fleeing the unthinkable in her home country, she longs to join her father in America. As Sera enters the halls of Ellis Island, she lives those same hopes, dreams, and challenges. The voices of real immigrants -- their suffering in steerage, their first glimpse of the Statue of Liberty, and their journey through the Great Hall -- complete this touching look into an important part of America's history. A pivotal time and place is brought to life through a combination of many voices speaking in harmony.

    She loved solving problems. And she loved pushing the limits of what girls and women were expected to do and be. In the mid-twentieth century, women were not welcome in the sciences, but Marie was tenacious. She got a job in a laboratory at Cambridge University, New York. But then she faced another barrior: women were not allowed on the research ships (they were considered bad luck on boats). So instead, Marie stayed back and dove deep into the data her colleagues recorded. She mapped point after point and slowly revealed a deep rift valley in the ocean floor. At first the scientific community refused to believe her, but her evidence was irrefutable. She proved to the world that her research was correct. The mid-ocean ridge that Marie discovered is the single largest geographic feature on the planet, and she mapped it all from her small, cramped office.

    Sarah Parcak welcomes you to the exciting new world of space archaeology, a growing field that is sparking extraordinary discoveries from ancient civilizations across the globe. In Archaeology from Space, Sarah Parcak shows the evolution, major discoveries, and future potential of the young field of satellite archaeology. From surprise advancements after the declassification of spy photography, to a new map of the mythical Egyptian city of Tanis, she shares her field’s biggest discoveries, revealing why space archaeology is not only exciting, but urgently essential to the preservation of the world’s ancient treasures.Parcak has worked in twelve countries and four continents, using multispectral and high-resolution satellite imagery to identify thousands of previously unknown settlements, roads, fortresses, palaces, tombs, and even potential pyramids. From there, her stories take us back in time and across borders, into the day-to-day lives of ancient humans whose traits and genes we share. And she shows us that if we heed the lessons of the past, we can shape a vibrant future. Includes Illustrations

    They defied the prejudices of the time. And they blazed a trail for generations of women to follow.What does it take to be an astronaut? Excellence at flying, courage, intelligence, resistance to stress, top physical shape — any checklist would include these. But when America created NASA in 1958, there was another unspoken rule: you had to be a man. Here is the tale of thirteen women who proved that they were not only as tough as the toughest man but also brave enough to challenge the government. They were blocked by prejudice, jealousy, and the scrawled note of one of the most powerful men in Washington. But even though the Mercury 13 women did not make it into space, they did not lose, for their example empowered young women to take their place in the sky, piloting jets and commanding space capsules. ALMOST ASTRONAUTS is the story of thirteen true pioneers of the space age.
