Download or read book Getting the Measure of the Stars written by W.A. Cooper and published by CRC Press. This book was released on 1989-01-01 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many years ago amateur astronomers made observations of equal quality to professionals and hence could participate in the intellectual challenge of advancing our knowledge of the universe. Throughout most of this century, however, the cost and complexity of telescopes and instruments have generally precluded their contribution. With the advent of home computers and relatively cheap electronics, the pendulum has swung back and the time is now ripe for amateurs to join their professional colleagues in the excitement of discovery. Getting the Measure of the Stars bridges the gap between dedicated amateurs and fully fledged professionals, both who seek to understand the nature and evolution of the stars. In terms accessible to the layperson, the first part explains how and why some stars have varying brightness, and what this variation can tell us about their physics and structure. The authors go on to discuss how to make brightness measurements, either by the unaided eye or by using photoelectric photometers. The book also discusses the accuracies of various methods and the limitations on projects. The final section describes possible projects, the observations required, and what these would do to enhance our understanding of the stars and the solar system. Incorporating a great deal of theoretical and observational expertise, this book is a vital source of reference for those wishing to maximize their enjoyment from the use of small telescopes.

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 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.

Available in PDF, EPUB and Kindle. Book excerpt: From the New York Times-bestselling author of The Secret World of Weather and The Lost Art of Reading Nature’s Signs, learn to tap into nature and notice the hidden clues all around you Before GPS, before the compass, and even before cartography, humankind was navigating. Now this singular guide helps us rediscover what our ancestors long understood—that a windswept tree, the depth of a puddle, or a trill of birdsong can help us find our way, if we know what to look and listen for. Adventurer and navigation expert Tristan Gooley unlocks the directional clues hidden in the sun, moon, stars, clouds, weather patterns, lengthening shadows, changing tides, plant growth, and the habits of wildlife. Rich with navigational anecdotes collected across ages, continents, and cultures, The Natural Navigator will help keep you on course and open your eyes to the wonders, large and small, of the natural world.

This book was released on 1992-05-31 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: The morphological scheme devised by Hubble and followers to classify galaxies has proven over many decades to be quite effective in directing our quest for the fundamental pa rameters describing the extragalactic manifold. This statement is however far more true for spirals than for ellipticals. Echoing the concluding remarks in Scott Tremaine's sum mary talk at the Princeton meeting on Structure and Dynamics of Elliptical Galaxies, "the Hubble classification of spirals is useful because many properties of spirals (gas con tent, spiral arm morphology, bulge prominence, etc. ) all correlate with Hubble time. By contrast, almost nothing correlates with the elliptical Hubble sequence El to E7. " During the last few years much effort has been put into the search for a more meaningful classification of ellipticals than Hubble's. Concomitantly, forwarded by some provocative conjectures by R. Michard, the classical question of whether E galaxies form a physically homogeneous family has been brushed up once more. Results of these and other parallel studies look rather promising and point to suture part of the dichotomy between ellipticals and disk galaxies which had become popular in the early eighties, owing to dynamical arguments. At the same time it appears more and more clear that, besides the usual genetic varieties of galaxies, products of environmental evolution must also be contemplated in building our modern picture of the "reign of galaxies" . The above considerations prompted us to solicit Prof.

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.

Book excerpt: ‘If you know me at all, you will know me as a liar.’ Kevin Carver is a household name. A popular TV soap star, he’s coasting through life in the same semi-detached, slightly smug way he’s always done. But when he callously dumps his much younger girlfriend Jade over supper one evening, he makes the first in a series of catastrophic mistakes. One poor decision leads to another and soon his whole life begins to unravel. He finds himself the subject of vitriolic press attacks, a police investigation and so much public loathing that he starts to wonder if he has any chance of receiving a fair trial. As the line blurs between his own life and that of the character he plays on TV, Kevin is forced to confront a lifetime of inadequacy in order to redeem himself. The Star Witness is the story of one man’s descent into disgrace and his journey to rejoin the human race. This pin-sharp satire on the shallows of modern media culture will keep you laughing, cringing and guessing until the very last page.
