Book Description
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 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 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
The Bible says the universe is just thousands of years old, and yet we can see stars that are billions of light-years away. Until now, creation scientists have not had a satisfactory answer to this puzzle, but the new cosmology outlined in this book offers a fresh and scientifically sound solution. Though he challenges some traditional creationist theories, Dr. Humphreys takes Scripture very straightforwardly, upholding its inerrancy and the idea of a young universe as he explains days one through four of creation week.

Book Description
This is a book about the physics of stars and starlight. The story of starlight is truly fascinating. Astronomers analyze and interpret the light from stars using photometry and spectroscopy, then inspirational detective work combines with the laws of physics to reveal the temperatures, masses, luminosities and outer structure of these far away points of light. The laws of physics themselves enable us to journey to the very center of a star and to understand its inner structure and source of energy! Starlight provides an in-depth study of stellar astrophysics that requires only basic high school mathematics and physics, making it accessible to all amateur astronomers. Starlight teaches amateur astronomers about the physics of stars and starlight in a friendly, easy-to-read way. The reader will take away a profoundly deeper understanding of this truly fascinating subject – and find his practical observations more rewarding and fulfilling as a result.

Book Description
This book presents a detailed pedagogical account of the equation of state and its applications in several important and fast growing topics in theoretical physics, chemistry and engineering. This book is the storv of the analysis of starlight by astronomical spectroscopy. It describes the development of the subject from the time of Joseph Fraunhofer, who, in 1814, used a telescope-mounted prism to observe the spectral light emitted from several bright stars. He discovered that light was missing at certain colours (wavelengths) in the starlight, and these so-called spectral lines were subsequently shown to hold clues to the nature of the stars themselves. The book explains how the classification of stars using their line spectra developed into a major branch of astronomy whilst new methods in astrophysics made possible the approximate quantitative analysis of spectral lines in the 1920s and 1930s. After the Second World War these techniques were considerably improved when computers were programmed to model the structure of the outer layers of stars. Basic concepts in spectroscopy and spectral analysis are also covered and. finally. Dr Hearnshaw comments on the stellar spectroscopy of some individual star.
