Book Description
"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.

Book Description
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.

Book Description
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.

Book Description
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 of 2017 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.

Book Description
"In 1781, William Herschel won international fame for discovering Uranus, the seventh planet from the sun. In documenting a new planet - something no one had done since the dawn of civilization - he expanded our perception that we are part of something much greater than the immediately visible solar system." "Herschel remains most famous for this discovery, but, as The Georgian Star makes vividly clear, he accomplished much more. After a successful career as a professional musician, he turned his attention to astronomy in his mid-thirties. With his sister Caroline as a partner, he pioneered techniques that are still used by astronomers today. The Herschels were the first to map the night sky, listing and categorizing every object they could see. To do so, they built a massive, forty-foot-tall telescope under the patronage of King George III. They were also the first to propose that the visible stars surrounding our little planet are only a fraction of those that make up a continually evolving universe. William's restless intelligence led further still, to the discovery of infrared radiation - invisible radiation that has a wavelength longer than microwaves but shorter than that of visible light. Caroline assembled an exhaustive catalog of nebulae, the beautiful, cloudy assemblages of dust and stellar light." "Erudite and accessible, The Georgian Star is a lively portrait of the pair who invented modern astronomy."--BOOK JACKET.

Book Description
"Starred Review. Reeves deploys his considerable writing skill in portraying Rutherford's personality ... capturing the full aspect of the man."—Booklist Born in colonial New Zealand, Ernest Rutherford grew up on the frontier—a different world from Cambridge, to which he won a scholarship at the age of twenty-four. His work revolutionized modern physics. Among his discoveries were the orbital structure of the atom and the concept of the "half-life" of radioactive materials. Rutherford and the young men working under him were the first to split the atom, unlocking tremendous forces—forces, as Rutherford himself predicted, that would bring us the atomic bomb. In Richard Reeves's hands, Rutherford comes alive, a ruddy, genial man and a pivotal figure in scientific history.
