At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges--Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates.The "glass universe" of half a million plates that Harvard amassed over the ensuing decades--through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography--enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard--and Harvard's first female department chair.

    . . is just one thing. But if I chop it in two, then chop the half in two, and keep on chopping, I get more and more bits, on and on, endlessly, to an infinity I could never ever reach.In 1887 in India, a boy named Ramanujan is born with a passion for numbers. He sees numbers in the squares of light pricking his thatched roof and in the beasts dancing on the temple tower. He writes mathematics with his finger in the sand, across the pages of his notebooks, and with chalk on the temple floor. "What is small?" he wonders. "What is big?" Head in the clouds, Ramanujan struggles in school -- but his mother knows that her son and his ideas have a purpose. As he grows up, Ramanujan reinvents much of modern mathematics, but where in the world could he find someone to understand what he has conceived?Author Amy Alznauer gently introduces young readers to math concepts while Daniel Miyares's illustrations bring the wonder of Ramanujan's world to life in the inspiring real-life story of a boy who changed mathematics and science forever. Back matter includes a bibliography and an author's note recounting more of Ramanujan's life and accomplishments, as well as the author's father's remarkable discovery of Ramanujan's Lost Notebook.

    Over 7,000 years ago Native Americans settled on the Nashua River, a beautiful and leafy valley. But the industrialization of nearby areas would lead to the deterioration of natural habitats. Each double spread examines brief periods of time when the river and surrounding areas teemed with wildlife. Lynne Cherry’s contrasting illustrations of the lush valley and the eventual polluted river deliver an astonishing look at our dramatic need for conservation efforts. This pictorial history of the river, edging towards a hopeful scene of modern-day descendants of both Native Americans and European settlers who come together to combat pollution and restore the beauty of the river, is an intelligent tale that shows young readers how they can do their part in taking care of the world around them, one river at a time.

    But the story of the Dutch colony of New Netherland was merely lost, not destroyed: 12,000 pages of its records–recently declared a national treasure–are now being translated. Drawing on this remarkable archive, Russell Shorto has created a gripping narrative–a story of global sweep centered on a wilderness called Manhattan–that transforms our understanding of early America.The Dutch colony pre-dated the “original” thirteen colonies, yet it seems strikingly familiar. Its capital was cosmopolitan and multi-ethnic, and its citizens valued free trade, individual rights, and religious freedom. Their champion was a progressive, young lawyer named Adriaen van der Donck, who emerges in these pages as a forgotten American patriot and whose political vision brought him into conflict with Peter Stuyvesant, the autocratic director of the Dutch colony. The struggle between these two strong-willed men laid the foundation for New York City and helped shape American culture. The Island at the Center of the World uncovers a lost world and offers a surprising new perspective on our own.

Excerpt: A Short History of Nearly Everything (ISBN 0-7679-0817-1) is a general science book by Bill Bryson, which explains some areas of science, using a style of language more accessible to the general public than many other books dedicated to the subject. It was the bestselling popular science book of 2005 in the UK, selling over 300,000 copies. A Short History deviates from Bryson's popular travel book genre, instead describing general sciences such as chemistry, paleontology, astronomy, and particle physics. In it, he explores time from the Big Bang to the discovery of quantum mechanics, via evolution and geology. Bryson tells the story of science through the stories of the people who made the discoveries, such as Edwin Hubble, Isaac Newton, and Albert Einstein. Bill Bryson wrote this book because he was dissatisfied with his scientific knowledge that was, not much at all. He writes that science was a distant, unexplained subject at school. Textbooks and teachers alike did not ignite the passion for knowledge in him, mainly because they never delved in the whys, hows, and whens. "It was as if wanted to keep the good stuff secret by making all of it soberly unfathomable." Bryson, on the state of science books used within his school. It was in his later years that he realized with stunning shame ...More: http: //booksllc.net/?id=101240

    Lynch brings a Mayflower voyager’s story to vivid life.At a young age, John Howland learned what it meant to take advantage of an opportunity. Leaving the docks of London on the Mayflower as an indentured servant to Pilgrim John Carver, John Howland little knew that he was embarking on the adventure of a lifetime.By his great good fortune, John survived falling overboard on the crossing of the Atlantic Ocean, and he earned his keep ashore by helping to scout a safe harbor and landing site for his bedraggled and ill shipmates. Would his luck continue to hold amid the dangers and adversity of the Pilgrims’ lives in New England?John Howland’s tale is masterfully told in his own voice, bringing an immediacy and young perspective to the oft-told Pilgrims’ story, P.J. Lynch captures this pivotal moment in American history in precise and exquisite detail, from the light on the froth of a breaking wave to the questioning voice of a teen in a new world.
