Cabinet Of Curiosities, A: The Myth, Magic And Measure Of Meteorites available in PDF, EPUB and Kindle. Hurtling through the atmosphere, in a blaze of light and reverberating percussions, the arrival of a meteorite on Earth is a magical, rare, and precious sight. These characteristics have accordingly ensured a long, yet often controversial history. For all this, meteorites are cosmic messengers. They tell us about the entire history of the solar system, their story carrying us from the very earliest moments, when solid material first began to form in the solar nebula. Indeed, meteorites played a key role in the origins of Earth's oceans and the genesis of life. Meteorites additionally tell us about the origin and evolution of the asteroids, and they tell us about impacts upon the Moon as well as the volcanic history of planet Mars. Much is known about the structure and chemistry of meteorites, but for all this, they still harbor many scientific mysteries that have yet to be resolved.

Download and read online ebook William Frederick Denning write by Martin Beech. This book was released on 2023-12-01. William Frederick Denning available in PDF, EPUB and Kindle. This book provides a detailed biographical account of the industrious late nineteenth-century astronomer William Frederick Denning who, in later life, rose to be a celebrated public figure and a highly respected amateur astronomer. The book also examines Denning’s many contributions to the astronomy of his time. As an indomitable promotor of amateur astronomy, Denning was closely involved in the formation of the short-lived, but historically pivotal, Observational Astronomy Society (OAS) in 1869. Readers will learn about the origins and the observational programs initiated by the OAS, and the author also presents a series of biographical sketches of its most industrious members. Furthermore, by examining Denning’s letters and publications, the author shows how he helped to nurture the growth of amateur astronomy, also teaching amateur observers how to make their efforts scientifically useful. A stalwart observer and enthusiast himself, Denning was a key player in the development of meteor astronomy in England, culminating in his being invited, in 1922, to be the first President of Commission 22 (meteors, meteorites and interplanetary dust) of the newly formed International Astronomical Union. The text follows the development and rapid growth of meteor astronomy during the nineteenth century, focusing upon the key observations and important theoretical advances. In addition, it pays tribute to pioneering practitioners, who, along with Denning, set out to unravel the story and secrets of the shooting stars. While not an openly forthright or strident figure, Denning, at the height of his career, became embroiled in two public and controversial issues. The first related to his pseudo-scientific theory of optical blurring, and his belief that large-aperture telescopes performed less efficiently than smaller-aperture telescopes when used in the study of planetary disks. The second concerned the mysterious issue of stationary meteor shower radiants—an apparent observational reduction that was completely at odds with both the standard theories of gravitational dynamics and the generally accepted notion of meteoroid stream structure. The book explores these two controversies and uses them to examine Denning’s outlook on scientific methodology.
Large-scale Peculiar Motions: Matter In Motion

Download and read online ebook Large-scale Peculiar Motions: Matter In Motion write by Gary A Wegner. This book was released on 2021-11-24. Large-scale Peculiar Motions: Matter In Motion available in PDF, EPUB and Kindle. All matter, including galaxy clusters, galaxies, and their constituents follow orbits and flows driven by the net attraction of near and distant masses. The book presents the development of studies of peculiar motions along with discoveries in large-scale structure, the cosmic microwave background, baryonic oscillations, gravity waves, and their relation to current work on gravitation and dark matter.The results of peculiar motion measurements in the late 20th century are described as they were used to search for the dipole of the galaxy motions, a determination of cosmic density, and to compare with the cosmic microwave dipole, which led to the discovery of galactic flows and the Great Attractor. Newer detailed measurements from surveys in the 21st century have helped resolve the nature of these structures. Some prospects for future investigations are discussed.

This book was released on 2022-01-17. Sun And The Other Stars Of Dante Alighieri, The: A Cosmographic Journey Through The Divina Commedia available in PDF, EPUB and Kindle. The Divine Comedy by Dante Alighieri is the story of a journey across the Universe as it was known in the Middle Ages, a work of science fiction ante litteram. Dante had an encyclopedic mind, no doubt, and his poem is the most widely read book after the Bible. He was a master of the astronomical knowledge of his time, and used astronomy in his work to indicate places, to measure time, and to exemplify beauty. Indeed, in the Convivio, he wrote that science is 'the ultimate perfection of our soul' and 'astronomy — more than any other science — is noble and high for a noble and high subject.'We propose a reading of the Divine Comedy through astronomy with a journey starting from the Earth, proceeding to the Moon, the planets, and to the outermost edges of the Universe. The way in which Dante connects ancient astronomy with modern conceptions of the cosmos will astonish readers more than 700 years later.

Download and read online ebook Black Holes, Cosmology And Extra Dimensions (Second Edition) write by Kirill A Bronnikov. This book was released on 2021-06-29. Black Holes, Cosmology And Extra Dimensions (Second Edition) available in PDF, EPUB and Kindle. Assuming basic knowledge of special and general relativity, this book guides the reader to problems under consideration in modern research, concerning black holes, wormholes, cosmology, and extra dimensions. Its first part is devoted to local strong field configurations (black holes and wormholes) in general relativity and its most relevant extensions: scalar-tensor, f(R), and multidimensional theories. The second part discusses cosmology, including inflation and problems of a unified description of the whole evolution of the universe. The third part concerns multidimensional theories of gravity and contains a number of original results obtained by the authors. Expository work is conducted for a mechanism of symmetries and fundamental constants formation. The original approach to nonlinear multidimensional gravity that is able to construct a unique perspective describing different phenomena is highlighted.Much of the content was previously presented only in journal publications and is new for book contents, e.g., on regular black holes, various scalar field solutions, wormholes and their stability, inflation, clusters of primordial black holes, and multidimensional gravity. The last two topics are added in this new edition of the book. The other chapters are also updated to include new discoveries like the detection of gravitational waves.
