Book excerpt: 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.

Norton & Company. This book was released on 2006-06-17 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Download or read book A Measure of Everything written by Marcus Weeks and published by Richmond Hill, Ont. : Firefly Books. This book was released on 2005 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive reference and history book on what is measured and why. Measurement is one of humankind's oldest and most vital activities. By measuring height, speed, size, temperature, strength and many other factors, humans can compare, improve and progress. In fact, measurement is an essential tool for survival. A Measure of Everything is a wide-ranging and comprehensive guide to what is measured and why. The book begins when the basic measurements were as simple as more, less and enough. As societies evolved, relative measurements were no longer sufficient. Advances in language allowed more precise measurements. Short distances were measured in relation to parts of the human body. For example, the ancient measurement cubit was the length of a pharaoh's arm plus the width of his hand. As society and culture progress and change, so do measurements. The rise of astronomy and the sciences demanded more exact measurements. These measurements are typically named after the discovering scientist, e.g., henry, curie, watt, rutherford, fahrenheit. This book features 28 categories organized into three sections: Earth and Life Sciences: astronomy, distance, time, meteorology, medicine, and five others. Physical Sciences: chemistry, mathematics, physics, speed, weight, temperature, and three others. Technology and Leisure: computers, engineering, finance, food, textiles, and four others. A Measure of Everything is an informative and entertaining book that will appeal to a wide range of readers.

Download or read book The Measure of All Things written by Ken Alder and published by Simon and Schuster. This book was released on 2014-07-29 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: In June 1792, amidst the chaos of the French Revolution, two intrepid astronomers set out in opposite directions on an extraordinary journey. Starting in Paris, Jean-Baptiste-Joseph Delambre would make his way north to Dunkirk, while Pierre-François-André Méchain voyaged south to Barcelona. Their mission was to measure the world, and their findings would help define the meter as one ten-millionth of the distance between the pole and the equator—a standard that would be used “for all people, for all time.” The Measure of All Things is the astonishing tale of one of history’s greatest scientific adventures. Yet behind the public triumph of the metric system lies a secret error, one that is perpetuated in every subsequent definition of the meter. As acclaimed historian and novelist Ken Alder discovered through his research, there were only two people on the planet who knew the full extent of this error: Delambre and Méchain themselves. By turns a science history, detective tale, and human drama, The Measure of All Things describes a quest that succeeded as it failed—and continues to enlighten and inspire to this day.

Book excerpt: INSTANT NEW YORK TIMES BESTSELLER - The Read With Jenna Today Show Book Club Pick! "A story of love and hope as interweaving characters display: how all moments, big and small, can measure a life. If you want joy, love, romance, and hope—read with us." —Jenna Bush Hager A luminous, spirit-lifting blockbuster that asks: would you choose to find out the length of your life? Eight ordinary people. One extraordinary choice. It seems like any other day. You wake up, drink a cup of coffee, and head out. But today, when you open your front door, waiting for you is a small wooden box. The contents of this mysterious box tells you the exact number of years you will live. From suburban doorsteps to desert tents, every person on every continent receives the same box. In an instant, the world is thrust into a collective frenzy. Where did these boxes come from? What do they mean? Is there truth to what they promise? As society comes together and pulls apart, everyone faces the same shocking choice: Do they wish to know how long they’ll live? And, if so, what will they do with that knowledge? The Measure charts the dawn of this new world through an unforgettable cast of characters whose decisions and fates interweave with one another: best friends whose dreams are forever entwined, pen pals finding refuge in the unknown, a couple who thought they didn’t have to rush, a doctor who cannot save himself, and a politician whose box becomes the powder keg that ultimately changes everything. Enchanting and deeply uplifting, The Measure is an ambitious, invigorating story about family, friendship, hope, and destiny that encourages us to live life to the fullest.

Download or read book Sidereus Nuncius Or The Sidereal Messenger written by Galileo Galilei and published by University of Chicago Press. This book was released on 1989-04-15 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Sidereus Nuncius (usually Sidereal Messenger, also Starry Messenger or Sidereal Message) is a short astronomical treatise (or pamphlet) published in New Latin by Galileo Galilei in March 1610. It was the first published scientific work based on observations made through a telescope, and it contains the results of Galileo's early observations of the imperfect and mountainous Moon, the hundreds of stars that were unable to be seen in either the Milky Way or certain constellations with the naked eye, and the Medicean Stars that appeared to be circling Jupiter.[1] The Latin word nuncius was typically used during this time period to denote messenger; however, albeit less frequently, it was also interpreted as message. While the title Sidereus Nuncius is usually translated into English as Sidereal Messenger, many of Galileo's early drafts of the book and later related writings indicate that the intended purpose of the book was "simply to report the news about recent developments in astronomy, not to pass himself off solemnly as an ambassador from heaven."[2] Therefore, the correct English translation of the title is Sidereal Message (or often, Starry Message)."--Wikiped, Nov/2014.

Download or read book Measurement written by Paul Lockhart and published by Harvard University Press. This book was released on 2012-09-25 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: For seven years, Paul Lockhart’s A Mathematician’s Lament enjoyed a samizdat-style popularity in the mathematics underground, before demand prompted its 2009 publication to even wider applause and debate. An impassioned critique of K–12 mathematics education, it outlined how we shortchange students by introducing them to math the wrong way. Here Lockhart offers the positive side of the math education story by showing us how math should be done. Measurement offers a permanent solution to math phobia by introducing us to mathematics as an artful way of thinking and living. In conversational prose that conveys his passion for the subject, Lockhart makes mathematics accessible without oversimplifying. He makes no more attempt to hide the challenge of mathematics than he does to shield us from its beautiful intensity. Favoring plain English and pictures over jargon and formulas, he succeeds in making complex ideas about the mathematics of shape and motion intuitive and graspable. His elegant discussion of mathematical reasoning and themes in classical geometry offers proof of his conviction that mathematics illuminates art as much as science. Lockhart leads us into a universe where beautiful designs and patterns float through our minds and do surprising, miraculous things. As we turn our thoughts to symmetry, circles, cylinders, and cones, we begin to see that almost anyone can “do the math” in a way that brings emotional and aesthetic rewards. Measurement is an invitation to summon curiosity, courage, and creativity in order to experience firsthand the playful excitement of mathematical work.

Download or read book Measure Solar System Objects and Their Movements for Yourself written by John D. Clark and published by Springer Science & Business Media. This book was released on 2009-04-20 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instead of taking somebody's word for it about the basic size and distance statistics for the solar system, this book shows amateur astronomers how to measure these things for themselves. This is an enriching experience for any amateur astronomer - to understand and personally measure some fundamental astronomical quantities and distances. A basic knowledge of geometry is required, but it is amazing how simple the geometry can be. Readers are led through the geometry as gently as possible - and in a light-hearted way - presuming that most non-academics will have half-forgotten most of their mathematics. The practical astronomical equipment recommended is no more than a typical commercially-made amateur telescope and a camera of some sort - these days a webcam works very well. Apart from that all the reader will need is access to a computer, the know-how to download free software, and an enthusiasm to expand his knowledge of the basis of scientific astronomy.
