Moulton - The definitive text for learning about the amazing science of Astronomy.\u003cbr\u003e\u003cbr\u003eThe progress of mankind has been marked by a number of great intellectual movements. At one time the ideas of men were expanding with the knowledge which they were obtaining from the voyages of Columbus, Magellan, and the long list of hardy explorers who first visited the remote parts of the earth. At another, millions of men laid down their lives in order that they might obtain toleration in religious beliefs. At another, the struggle was for political freedom. It is to be noted with satisfaction that those movements which have involved the great mass of people, from the highest to the lowest, have led to results which have not been lost.\u003cbr\u003e\u003cbr\u003eThe present age is known as the age of science. Never before have so many men been actively engaged in the pursuit of science, and never before have its results contributed so enormously to the ordinary affairs of life. If all its present-day applications were suddenly and for a considerable time removed, the results would be disastrous. With the stopping of trains and steamboats the food supply in cities would soon fail, and there would be no fuel with which to heat the buildings. Water could no longer be pumped, and devastating fires might follow. If people escaped to the country, they would perish in large numbers because without modern machinery not enough food could be raised to supply the population. In fact, the more the subject is considered, the more clearly it is seen that at the present time the lives of civilized men are in a thousand ways directly dependent on the things produced by science.\u003cbr\u003e\u003cbr\u003eAstronomy is a science. That is, it is one of those subjects, such as physics, chemistry, geology, and biology, which have made the present age in very many respects altogether different from any earlier one. Indeed, it is the oldest science and the parent of a number of the others, and, in many respects, it is the most perfect one. For these reasons it illustrates most simply and clearly the characteristics of science. Consequently, when one enters on the study of astronomy he not only begins an acquaintance with a subject which has always been noted for its lofty and unselfish ideals, but, at the same time, he becomes familiar with the characteristics of the scientific movement.\u003cbr\u003e\u003cbr\u003eCHAPTER I \u003cbr\u003e Science\u003cbr\u003e\u003cbr\u003eCHAPTER II\u003cbr\u003eThe Earth\u003cbr\u003e                 The Shape of the Earth\u003cbr\u003e                 The Mass of the Earth and the Condition of its Interior\u003cbr\u003e                 The Earth’s Atmosphere\u003cbr\u003e\u003cbr\u003eCHAPTER III\u003cbr\u003eThe Motions Of The Earth\u003cbr\u003e                  The Rotation of the Earth    \u003cbr\u003e                  The Revolution of the Earth\u003cbr\u003e               \u003cbr\u003eCHAPTER IV\u003cbr\u003eReference Points and Lines\u003cbr\u003e\u003cbr\u003eCHAPTER V\u003cbr\u003eThe Constellations\u003cbr\u003e\u003cbr\u003eCHAPTER VI\u003cbr\u003eTime\u003cbr\u003e\u003cbr\u003eCHAPTER VII\u003cbr\u003eThe Moon\u003cbr\u003e\u003cbr\u003eCHAPTER VIII\u003cbr\u003eThe Solar System\u003cbr\u003e                 The Law of Gravitation\u003cbr\u003e                  Orbits, Dimensions, and Masses of the Planets\u003cbr\u003e                  \u003cbr\u003eCHAPTER IX\u003cbr\u003eThe Planets\u003cbr\u003e                  Mercury and Venus\u003cbr\u003e                  Mars\u003cbr\u003e                  Jupiter\u003cbr\u003e                  Saturn\u003cbr\u003e                  Uranus and Neptune\u003cbr\u003e\u003cbr\u003eCHAPTER X\u003cbr\u003eComets And Meteors\u003cbr\u003e                   Comets\u003cbr\u003e                   Meteors\u003cbr\u003e\u003cbr\u003eCHAPTER XI\u003cbr\u003eThe Sun\u003cbr\u003e                  The Sun’s Heat\u003cbr\u003e                  Spectrum Analysis\u003cbr\u003e                  The Constitution of the Sun  \u003cbr\u003e                    \u003cbr\u003eCHAPTER XII\u003cbr\u003eEvolution Of The Solar System\u003cbr\u003e                  General Considerations on Evolution\u003cbr\u003e                  Data of Problem of Evolution of Solar System\u003cbr\u003e                  The Planetesimal Theory\u003cbr\u003e                  Historical Cosmogonies\u003cbr\u003e                  \u003cbr\u003eCHAPTER XIII\u003cbr\u003eThe Sidereal Universe\u003cbr\u003e                   The Apparent Distribution of the Stars\u003cbr\u003e                   Distances and Motions of the Stars\u003cbr\u003e                   The Stars\u003cbr\u003e                   The Nebulæ","brand":"Moulton","offers":[{"title":"Default Title","offer_id":47066831847664,"sku":"2940016697314","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940016697314_p0.jpg?v=1763640439","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940016697314","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
