Book Description
Here, one of the world's leading astrophysicists provides the first comprehensive and logically structured overview of the many ideas and discoveries pertaining to the supermassive black hole at the galactic center known as Sagittarius A*. By far the closest galactic nucleus in the universe, Sagittarius A* alone can provide us with a realistic expectation of learning about the physics of strong gravitational fields, and the impact of such fields on the behavior of matter and radiation under severe physical conditions. Its proximity may even provide the opportunity to directly test one of general relativity's most enigmatic predictions--the existence of closed pockets of space-time hidden behind an event horizon. The plethora of research on Sagittarius A* since its discovery in 1974 has long seemed an interwoven pattern of loose threads. No one has successfully synthesized this growing body of work into a manageable, coherent book both for professional researchers and for students taking courses focusing on black holes and galactic nuclei--until now. With Fulvio Melia's The Galactic Supermassive Black Hole, readers finally have at their disposal a one-volume crucible of essential ideas, logically streamlined but with thorough references for those wishing to explore the various topics in greater depth.

Book Description
Two novellas about family life and fraudsters by one of the twentieth century's best Italian novelists. Valentino and Sagittarius are two of Natalia Ginzburg’s most celebrated works: tales of love, hope, and delusion that are full of her characteristic mordant humor, keen psychological insight, and unflinching moral realism. Valentino is the spoiled child of doting parents, who have no doubt that their handsome young son will prove “a man of consequence.” Nothing that Valentino does—his nights out on the town, his failed or incomplete classes—suggests there is any ground for that confidence, and Valentino’s sisters view their parents and brother with a mixture of bitterness, stoicism, and bemusement. Everything becomes that much more confused when, out of the blue, Valentino finds an enterprising, wealthy, and strikingly ugly wife, who undertakes to support not just him but the whole family. Sagittarius is another story of misplaced confidence recounted by a wary daughter, whose mother, a grass widow with time on her hands, moves to the suburbs, eager to find new friends. Brassy, bossy, and perpetually dissatisfied, especially when it comes to her children, she strikes up a friendship with the mysterious Scilla, and soon the two women are planning to open an art gallery. But knowing better than everyone, it turns out, is not that different from knowing nothing at all.

Book Description
Marvel at the wonders of the universe, from stars and planets to black holes and nebulae, in this exploration of our solar system and beyond. Universe opens with a look at astronomy and the history of the Universe, using 3D artworks to provide a comprehensive grounding in the fundamental concepts of astronomy, including the basic techniques of practical astronomy. The core of the book is a tour of the cosmos covering the Solar System, the Milky Way, and galaxies beyond our own. Explanatory pages introduce different celestial phenomena, such as galaxies, and are followed by catalogs that profile the most interesting and important examples. A comprehensive star atlas completes the picture, with entries on each of the 88 constellations and a monthly sky guide showing the night sky as it appears throughout the year as viewed from both the northern and southern hemispheres.
