Time,Space,Stars and Man-The Story of the Big Bang

• Hardcover: 496 pages
• Publisher: World Scientific Publishing Company (April 2009)
• Language: English
• ISBN-10: 1848162723
• ISBN-13: 978-1848162723

Most well-read, but non-scientific, people will have heard of the term 'Big Bang' as a description of the origin of the Universe. They will recognize that DNA identifies individuals and will know that the origin of life is one of the great unsolved scientific mysteries. This book brings together all of that material. Starting with the creation of space and time - known as the Big Bang - the book traces causally related steps through the formation of matter, of stars and planets, the Earth itself, the evolution of the Earth's surface and atmosphere, and then through to the beginnings of life and the evolution of man. The material is presented in such a way that an intelligent non-scientist can comprehend it, without using formulae or equations but still preserving the integrity of the involved science.This book does not solve the mysteries of what initiated the Big Bang or how life evolved from inanimate matter, but it does make clear the nature of those problems. The reader will be left with a sense of wonderment that he or she actually exists!

Space - From Earth to the Edge of the Universe

• Hardcover: 360 pages
• Publisher: DK Publishing (October 4, 2010)
• Language: English

Featuring a wealth of incredible astronomical photographs, Space is perfect for anyone interested in astronomy, space imagery, and the history of space exploration. Space takes us on an imaginary journey that starts on a launch pad, goes toward the center of our Solar System to see the inner planets and the Sun, and then flies outward past the outer planets and on to the fringes of the Solar System.

Space – From Earth to the Edge of the Universe by editors Carole Stott, Robert Dinwiddie, David Hughes and Giles Sparrow; Dorling Kindersley(DK) Publishing; New York, New York; $40.00 (hard cover); 2010.

Space is big…but so is this large format book. This is a captivating and nicely packaged volume that includes a wealth of space exploration and astronomical imagery.

The editors and senior art editors and designers clearly worked together here to pull together a picture-perfect look at the origins of human space exploits, current status, and the unknown unknowns awaiting discovery and investigation within the Universe at large.

Just the table of contents gives you an eyeful that will set you page turning. From launch pad Earth and our neighboring worlds to beyond the asteroid belt into a galaxy of stars and a universe of galaxies to the outer limits.

One thing that truly stands out in this book is not only how much exploration has been started, but also how much is ahead of us.

Right up front, the reader will find a quote from Stephen Hawking, world renowned cosmologist: “I don’t think the human race will survive the next thousand years, unless we spread into space.”

This volume will help you book your travel plans, be it to the Moon or Mars – or to help satisfy your hunger for deep space travel.

This over 350-page book comes complete with a very generous reference section and glossary.
But the real eye-catching value of this work is the layout and explanatory graphics and text. It’s laden with descriptive artwork that provides expert and novice alike a new appreciation for the complexities of astronomical surveys and human and robotic space exploration.

Astronomy for Entertainment (by Yakov Perelman)

Astronomy is a fortunate science; it needs no embellishments, said the French savant Arago. So fascinating are its achievements that no special effort is needed to attract attention. Nonetheless, the science of the heavens is not only a collection of astonishing revelations and daring theories. Ordinary facts, things that happen, day by day, are its substance. Most laymen have, generally speaking, a rather hazy notion of this prosaic aspect of astronomy. They find it of little interest, for it is indeed hard to concentrate on what is always before the eye.

Everyday happenings in the sky are the contents of this book, free from professional terminology with easy reading. Its purpose is to initiate the reader into the basic facts of astronomy. Ordinary facts with which you may be acquainted are couched here in unexpected paradoxes, or slanted from an odd and unexpected angle solely to excite the imagination and quicken your interest. The daily aspect of the science of the skies, its beginnings, not later findings that mainly form the contents of Astronomy for Entertainment. The purpose of the book is to initiate the reader into the basic facts of astronomy. Ordinary facts with which you may be acquainted are couched here in unexpected paradoxes, or slanted from an odd and unexpected angle. The theme is, as far as possible, free from "terminology" and technical paraphernalia that so often make the reader shy of books on astronomy.

Books on popular science are often rebuked for not being sufficiently serious. In a way the rebuke is just, and support for it can be found (if one has in mind the exact natural sciences) in the tendency to avoid calculations in any shape or form. And yet the reader can really master his subject only by learing how to reckon, even though in a rudimentary fashion. Hence, both in Astronomy for Entertainment and in other books of this series, the aurhor has not attempted to avoid the simplest of calculations. True, he has taken care to present them in an easy form, well within the reach of all who have studied mathematics at school. It is his conviction that these exercises help not only retain the knowledge acquired; they are also a useful introduction to more serious reading.

This book contains chapters relating to the Earth, the Moon, planets, stars and gravitation. The author has concentated in the main on materials not usually discussed in works of this nature. Subjects omitted in the present book, will, he hopes, be treated in a second volume. The book, it should be said, makes no attempt to analyze in detail the rich content of modern astronomy.

Unfortunately Y. Perelman never wrote the continuation he had planned for this book, as untimely death in warbound Leningrad in 1942 interruped his labours.

Astronomy - A Self Teaching Guide - Dinah L.Moche

Astronomy is a user-friendly guide for beginners. Chapters make it easy for you to quickly learn the main topics of a college level course. Sections clarify basic principles and contemporary advances. The Index enables you to look up concepts, definitions, facts and famous astronomers, fast. You can use the book alone or with a conventional textbook, Internet based or distance-learning course, computer software, telescope manual, or as a handy reference.

A list of objectives for each chapter tells you instantly what information is contained there. The first time a new term is introduced, it appears in bold type and is defined. Topics in each chapter are presented in short, numbered sections. Each section contains new information and usually asks you to answer a question or asks you to suggest an explanation, analyze, or summarize as you go along. You will always see the answer to the question right after you have answered it. If your answer agrees with the book’s, you understand the material and are ready to proceed to the next section. If it does not, you should review some previous sections to make sure you understand the material before you proceed.

A self-test at the end of each chapter lets you find out fast how well you understand the material in the chapter. You may test yourself right after completing a chapter, or you might take a break and then take the self-test as a review before beginning a new chapter. Compare your answers with the book’s. If your answers do not agree with the printed ones, review the appropriate sections (listed next to each answer).

On a clear night in a place where the sky is really dark, you can see about 2000 stars with your unaided eye. You can look trillions of kilometers into space and peer thousands of years back into the distant past. As you gaze at the stars you may wonder: What is the pattern or meaning of the starry heavens? What is my place in the vast cosmos? You are not alone in asking these questions. The beauty and mystery of space have always fascinated people.

Astronomy is the oldest science—and the newest. Exciting discoveries are being made today with the most sophisticated tools and techniques ever available. Yet dedicated amateurs can still make important contributions. This book will teach you the basic concepts of astronomy and space exploration. You will more fully enjoy observing the stars as your knowledge and understanding grow. You will be better able to surf the Web and to read more on topics that intrigue you, from ancient astronomy to the latest astrophysical theories and spaceflights. Now, begin reading about the enormous tracts of space and time we call the universe, and stretch your mind!

Introduction to Astronomy and Cosmology - Ian Morison (eBook)

Astronomy is probably the oldest of all the sciences. It differs from virtually all other science disciplines in that it is not possible to carry out experimental tests in the laboratory. Instead, the astronomer can only observe what he sees in the Universe and see if his observations fit the theories that have been put forward. 

Astronomers do, however, have one great advantage: in the Universe, there exist extreme states of matter which would be impossible to create here on Earth. This allows astronomers to make tests of key theories, such as Albert Einstein’s General Theory of Relativity. In this fi rst chapter, we will see how two precise sets of obser-vations, made with very simple instruments in the sixteenth century, were able to lead to a significant understanding of our Solar System. In turn, these helped in the formulation of Newton’s Theory of Gravity and subsequently Einstein’s General Theory of Relativity – a theory of gravity which underpins the whole of modern cosmology. In order that these observations may be understood, some of the basics of observational astronomy are also discussed.

One of the first triumphs of observational astronomy was Galileo’s series of obsevations of Venus which showed that the Sun, not the Earth, was at the center of the Solar System so proving that the Copernican, rather than the Ptolemaic, model was correct In the Ptolemaic model of the Solar System (which is more subtle than is often acknowledged), the planets move around circular ‘epicycles’ whose centres move around the Earth in larger circles, called deferents.  This enables it to account for the ‘retrograde’ motion of planets like Mars and Jupiter when they appear to move backwards in the sky. It also models the motion of Mercury and Venus.

Galileo’s observations, made with the simplest possible astronomical instrument, were able to show which of the two competing models of the Solar System was correct. In just the same way, but using vastly more sophisticated instruments, astronomers have been able to choose between competing theories of the Universe.

Looking up at the heavens on a clear night, we can imagine that the stars are located on the inside of a sphere, called the celestial sphere, whose centre is the centre of the Earth.

Astronomy: The Solar System and Beyond, 6 Edition (ebook)

Description -

Michael A. Seeds, Dana Backman, "Astronomy: The Solar System and Beyond, 6 Edition"
Br..ks.C.e | 2009 |512 pages | PDF | 61.8 MB

With this newly revised 6th edition of ASTRONOMY: THE SOLAR SYSTEM AND BEYOND, Mike Seeds and Dana Backman's goal is to help students use astronomy to understand science and use science to understand what we are. Fascinating and engaging, this text illustrates the scientific method and guides students to these fundamental questions: "What are we?" and "How do we know?" In discussing the interplay between evidence and hypothesis, The authors provide not just facts, but a conceptual framework for understanding the logic of science. The book vividly conveys their love of astronomy, and illustrates how students can comprehend their place in the universe by grasping a small set of physical laws. Crafting a story about astronomy, The authors show students how to ask questions to gradually puzzle out the beautiful secrets of the physical world. With the use of mathematics set off in boxes, the book's presentation is flexible and allows instructors to teach to differing student levels. This is the only Seeds/Backman text to be written using a traditional planets-first approach. The revision addresses new developments in astrophysics and cosmology, plus the latest discoveries, from Mars' buried water to proto-galaxies at the limits of the observable universe.

Where Did The Moon Come From? (eBook)

The current standard theory of the origin of the Moon is that the Earth was hit by a giant impactor the size of Mars causing ejection of iron poor impactor mantle debris that coalesced to form the Moon. But where did this Mars-sized impactor come from? Isotopic evidence suggests that it came from 1AU radius in the solar nebula and computer simulations are consistent with it approaching Earth on a zero-energy parabolic trajectory. But how could such a large object form in the disk of planetesimals at 1AU without colliding with the Earth early-on before having a chance to grow large or before its or the Earth's iron core had formed? We propose that the giant impactor could have formed in a stable orbit among debris at the Earth's Lagrange point $L_4$ (or $L_5$). We show such a configuration is stable, even for a Mars-sized impactor. It could grow gradually by accretion at $L_4$ (or $L_5$), but eventually gravitational interactions with other growing planetesimals could kick it out into a chaotic creeping orbit which we show would likely cause it to hit the Earth on a zero-energy parabolic trajectory. This paper argues that this scenario is possible and should be further studied.

The Birth And Death Of The Sun (eBook)

How did our sun come into being? What keeps it hot and luminous, and what will be its ultimate fate? In this fascinating and informative book, George Gamow - renowned physicist and author of the best-seller One Two Three... Infinity - outlines the discoveries and theories that illuminate the evolution of our world. One of the founders of Big Bang theory, Gamow employs language that's both scientifically accurate and simple enough for nonspecialists to trace the development of atomic theory from its earliest articulation in 375 B.C. through studies of nuclear reactions and radioactive decay. Along the way, he discusses the formation of the stars and planets, the nature of red and white dwarfs, the dimensions of our stellar system, and the infinity of space. 1952 ed. 60 figures. 18 halftones.
