Product Description
In this fascinating Very Short Introduction, popular science writer John Gribben tells the story of our growing understanding of galaxies, from the days before Galileo to our present-day observations of our many hundreds of millions of galactic neighbors. Not only are galaxies fascinating astronomical structures in themselves, but their study has revealed much of what we know today about the cosmos, providing a window on the Big Bang and the origins of the Universe. Gribben looks at our own "Milky Way" Galaxy in detail, from the different kinds of stars that are born within it, to the origins of its magnificent spiral structure. Perhaps most interesting, Gribben describes the many exciting discoveries have been made about our own galaxy and about those beyond: how a supermassive black hole lurks at the center of every galaxy, how enormous forces are released when galaxies collide, how distant galaxies provide a window on the early Universe, and how the formation of young galaxies shed needed light on the mysteries of Cold Dark Matter.

A great first introduction to Galaxies by Bojan Tunguz (Greencastle, IN USA)

Of all the astronomical objects that are visible to the human eye, perhaps the most fascinating ones are the galaxies. This is in large measure due to the most familiar elliptical galaxies, of which our own Milky Way is an example. Their twirling, irregular shapes are fascinating to the eye, for more or less the same reasons that the rings of Saturn attract attention. They are an exception to the universe that is filled with perfectly spherical or pointlike objects, with very little of internal structure. And just like Saturn, the fascinating shape of the galaxies has only been revealed with the advent of a telescope, and not until well into the 20th century did we realize that these "island universes" lay far outside out of the Milky Way. If you are interested in finding out more about galaxies, what they are, how did we come to know about them, how they develop, and what their ultimate destiny is, then John Gribbin's book is an excellent introduction to the subject. It is accessible to a non-expert, and very little scientific understanding is assumed. It is very readable and interesting, and it will take a reader on a fascinating intellectual journey across the universe. After reading this book, you will be looking at the universe with a whole new set of eyes, and would hopefully appreciate our own place in cosmos.

	Cosmology: A Very Short Introduction (Very Short Introductions) by Peter Coles (Author) Written in simple and accessible language, this non-technical introduction to cosmology, or the creation and development of the universe, explains the discipline, covers its history, details the latest developments, and explains what is known, what is believed, and what is purely speculative. In addition, the author discusses the development of the Big Bang theory, and more speculative modern issues like quantum cosmology, superstrings, and dark matter.

Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing-and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity. It is now over a hundred years since he made these discoveries,...

	Chaos: A Very Short Introduction (Very Short Introductions) by Lenny Smith (Author), Leonard Smith (Author) Chaos exists in systems all around us. Even the simplest system can be subject to chaos, denying us accurate predictions of its behavior, and sometimes giving rise to astonishing structures of large-scale order. Here, Leonard Smith shows that we all have an intuitive understanding of chaotic systems. He uses accessible math and physics to explain Chaos Theory, and points to numerous examples in philosophy and literature that illuminate the problems. This book provides a complete understanding...
