"A short, excellent account of [Leavitt’s] extraordinary life and achievements." —Simon Singh, New York Times Book Review George Johnson brings to life Henrietta Swan Leavitt, who found the key to the vastness of the universe—in the form of a “yardstick” suitable for measuring it. Unknown in our day, Leavitt was no more recognized in her own: despite her enormous achievement, she was employed by the Harvard Observatory as a mere number-cruncher, at a wage not dissimilar from that of workers in the nearby textile mills. Miss Leavitt’s Stars uncovers her neglected history.

A century ago, a brilliant woman found the key to the vastness of the universe; her name was Henrietta Swan Leavitt. She was hired by Harvard Univ. to calculate the positions and luminosities of stars in astronomical photos. She discovered a new law, one that would transform the field of cosmology. Because of Leavitt¿s discovery, astronomers could use a kind of star known as a ¿variable¿ as a cosmic yardstick. Her law settled an important astronomical question; how big is the universe? Using Leavitt¿s law, the astronomer Edwin Hubble was able to prove that there were galaxies beyond the Milky Way, and that the universe is unfathomably large. ¿A masterly account of how we measure the universe and the moving story of a neglected genius.¿ Illus.

Henrietta Levitt was the first person to discover the scientific importance of a star’s brightness—so why has no one heard of her? Learn all about a female pioneer of astronomy in this picture book biography with audio. Henrietta Swan Leavitt was born on July 4, 1868, and she changed the course of astronomy when she was just twenty-five years old. Henrietta spent years measuring star positions and sizes from photographs taken by the telescope at the Harvard College Observatory, where she worked. After Henrietta observed that certain stars had a fixed pattern to their changes, her discovery made it possible for astronomers to measure greater and greater distances—leading to our present understanding of the vast size of the universe. An astronomer of her time called Henrietta Leavitt “one of the most important women ever to touch astronomy,” and another close associate said she had the “best mind at the Harvard Observatory.” Henrietta Leaveitt's story will inspire young women and aspiring scientists of all kinds and includes additional information about the solar system and astronomy. This eBook edition also includes audio accompaniment.

From #1 New York Times bestselling author Dava Sobel, the "inspiring" (People), little-known true story of women's landmark contributions to astronomy A New York Times Book Review Notable Book Named one of the best books of the year by NPR, The Economist, Smithsonian, Nature, and NPR's Science Friday Nominated for the PEN/E.O. Wilson Literary Science Writing Award "A joy to read.” —The Wall Street Journal In the mid-nineteenth century, the Harvard College Observatory began employing women as calculators, or “human computers,” to interpret the observations their male counterparts made via telescope each night. 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. Elegantly written and enriched by excerpts from letters, diaries, and memoirs, The Glass Universe is the hidden history of the women whose contributions to the burgeoning field of astronomy forever changed our understanding of the stars and our place in the universe.

The story of Noah's flood is one of the best-loved and most often retold biblical tales, the inspiration for numerous children's books and toys, novels, and even films. Whether as allusion, archetype, or literal presence--the American landscape is peppered with "recreations" of the ark--the story of Noah's animals and the ark resonates throughout American culture and the world. While most think of Noah's ark as a dramatic myth, others are consumed by the quest for geological and archeological proof that the flood really occurred. Persistent rumors of a large vessel on the mountain of Ararat in Turkey, for instance, have led many pilgrims and explorers over the centuries to visit that fabled peak. Recent finds suggest that there may have been a catastrophic flood on the shores of the Black Sea some 7,600 years ago. Is this then the reality behind the ancient tale of Noah? More to the point, why does it matter? What does the story of the Flood mean to us and why does it so stir the collective imagination? When the Great Abyss Opened examines the history of our attempts to understand the Flood, from medieval Jewish and Christian speculation about the physical details of the ark to contemporary efforts to link it to scientific findings. Unraveling the mythical dimensions of the parallel Mesopotamian flood stories and their deeper social and psychological significance, J. David Pleins also considers the story's positive uses in theology and moral instruction. Noah's tale, however, has also been invoked as a means of justifying exclusion, racism, and anti-homosexual views. Pro-slavery advocates, for example, used the story of Noah's Curse on Ham's son Canaan to rationalize the enslavement of Africans. Throughout this expansive and lively book, Pleins sheds new light on our continuing attempts to understand this ancient primal myth. Noah's Flood, he contends, offers a unique case study that illuminates the timeless and timely question of how fact and faith relate.

Our fascination with numbers begins when we are children and continues throughout our lives. We start counting our fingers and toes and end up balancing checkbooks and calculating risk. So powerful is the appeal of numbers that many people ascribe to them a mystical significance. Other numbers go beyond the supernatural, working to explain our universe and how it behaves. Cosmic Numbers, mathematics professor James D. Stein traces the discovery, evolution, and interrelationships of the numbers that define our world. Everyone knows about the speed of light and absolute zero, but numbers like Boltzmann's constant and the Chandrasekhar limit are not as well known, and they do far more than one might imagine: They tell us how this world began and what the future holds. Much more than a gee-whiz collection of facts and figures, Cosmic Numbers illuminates why particular numbers are so important -- both to the scientist and to the rest of us.

It was not always known that the Milky Way is just one of many galaxies in the universe. Edwin Hubble is the man who discovered this startling idea and that the universe was expanding. As a result of these discoveries, Hubble became an international celebrity, and is remembered today as a genius of science.
