Dust In The Universe

- First book to present a comprehensive study of dust in the universe

Requiring no astronomical background, this excellent introductory examines the physics of dust particles in interstellar, circumstellar and extragalactic space. After presenting relevant astronomical concepts, the author discusses the physical properties of dust grains, their growth and destruction and the observations of dust in the aforementioned environments.

Without interstellar dust, the Universe as we see it today would not exist. Yet at first we considered this vital ingredient merely an irritating fog that prevented a clear view of the stars and nebulae in the Milky Way and other galaxies. We now know that interstellar dust has essential roles in the physics and chemistry of the formation of stars and planetary systems, the creation of the building blocks of life, and in the movement of those molecules to new planets. This is the story in this book. After introducing the materials this interstellar dust is made of, the authors explain the range of sizes and shapes of the dust grains in the Milky Way galaxy and the life cycle of dust, starting from the origins of dust grains in stellar explosions through to their turbulent destruction. Later on we see the variety of processes in interstellar space involving dust and the events there that cause the dust to change in ways that astronomers and astrobiologists can use to indirectly observe those events. This book is written for a general audience, concentrating on ideas rather than detailed mathematics and chemical formulae, and is the first time interstellar dust has been discussed at an accessible level.

A World From Dust describes how a set of chemical rules combined with the principles of evolution in order to create an environment in which life as we know it could unfold. Beginning with simple mathematics, these predictable rules led to the advent of the planet itself, as well as cells, organs and organelles, ecosystems, and increasingly complex life forms. McFarland provides an accessible discussion of a geological history as well, describing how the inorganic matter on Earth underwent chemical reactions with air and water, allowing for life to emerge from the world's first rocks. He traces the history of life all the way to modern neuroscience, and shows how the bioelectric signals that make up the human brain were formed. Most popular science books on the topic present either the physics of how the universe formed, or the biology of how complex life came about; this book's approach would be novel in that it condenses in an engaging way the chemistry that links the two fields. This book is an accessible and multidisciplinary look at how life on our planet came to be, and how it continues to develop and change even today. This book includes 40 illustrations by Gala Bent, print artist and studio faculty member at Cornish College of the Arts, and Mary Anderson, medical illustrator.

In a stylish, smart, new military science fiction series, Richard Baker begins the adventures of Sikander North in an era of great interstellar colonial powers. Valiant Dust combines the intrigues of interstellar colonial diplomacy with explosive military action. “New and extraordinary . . . Go read this!”—David Weber Sikander Singh North has always had it easy—until he joined the crew of the Aquilan Commonwealth starship CSS Hector. As the ship’s new gunnery officer and only Kashmiri, he must constantly prove himself better than his Aquilan crewmates, even if he has to use his fists. When the Hector is called to help with a planetary uprising, he’ll have to earn his unit’s respect, find who’s arming the rebels, and deal with the headstrong daughter of the colonial ruler—all while dodging bullets. Sikander’s military career is off to an explosive start—but only if he and CSS Hector can survive his first mission.
