Why is there no dust in elliptical galaxies? Firstly, the universe is rational and the rationality is proportion at large scale systems such as galaxies. Proportion means that the distribution of matters in the universe is orderly. For example, there are four giants standing in array. Their heights are respectively A, B, C, D, and A, B stand in the first row from left to right, C, D in the second row from left to right. Proportion requires that A divided by C be equal to B divided by D. Rational structures are either circularly symmetric with respect to the center point, or bilaterally symmetric. Secondly, spiral galaxy arms are neither circularly symmetric nor bilaterally symmetric. Therefore, arms are not rational structure. Arm patterns exist only in spiral galaxies and they are weak compared with the main disk structure of spiral galaxies. Therefore, the presence of arm structure is the disturbance to the rational structure. Because arm patterns exist only in spiral galaxies and only spiral galaxies present dust, Dr. He comes to the critical answer to the above question: any disturbance to rational structure produces cosmic dust! From now on we call the disturbance to rational structure the cosmic impulse. Therefore, the universe is originated not only rationally but also impulsively!

The Origin and Evolution of Galaxies is the outstanding problem of modern cosmology. Fortunately. we have a firm cosmological framework on which to base our theories (the hot big bang) and recently there has been substantial progress in providing observations which potentially can constrain these theories. The problem of galaxy formation is. as a consequence. one involving many diverse branches of physics and astrophysics. It has been the aim of the school. and this compendium of lectures and seminars. to bring together these diverse aspects at a level enabling research workers to understand what is going on in other corners of the subject and to see how progress in each area impinges on the others. We are grateful to the contributors to this volume for allowing us considerable editorial license with their articles. We have attempted to provide a representative sample of the talks that were given at the school besides the texts of the invited lecturers. It is regrettable that for reasons of space we have had to leave out a number of other contributions.

Delineating the huge strides taken in cosmology in the past ten years, this much-anticipated second edition of Malcolm Longair's highly appreciated textbook has been extensively and thoroughly updated. It tells the story of modern astrophysical cosmology from the perspective of one of its most important and fundamental problems – how did the galaxies come about? Longair uses this approach to introduce the whole of what may be called "classical cosmology". What’s more, he describes how the study of the origin of galaxies and larger-scale structures in the Universe has provided us with direct information about the physics of the very early Universe.

This volume contains the updated and expanded lecture notes of the 37th Saas-Fee Advanced Course organised by the Swiss Society for Astrophysics and Astronomy. It offers the most comprehensive and up to date review of one of the hottest research topics in astrophysics - how our Milky Way galaxy formed. Joss Bland-Hawthorn & Ken Freeman lectured on Near Field Cosmology - The Origin of the Galaxy and the Local Group. Francesca Matteucci’s chapter is on Chemical evolution of the Milky Way and its Satellites. As designed by the SSAA, books in this series – and this one too – are targeted at graduate and PhD students and young researchers in astronomy, astrophysics and cosmology. Lecturers and researchers entering the field will also benefit from the book.

This edition of Science and Creationism summarizes key aspects of several of the most important lines of evidence supporting evolution. It describes some of the positions taken by advocates of creation science and presents an analysis of these claims. This document lays out for a broader audience the case against presenting religious concepts in science classes. The document covers the origin of the universe, Earth, and life; evidence supporting biological evolution; and human evolution. (Contains 31 references.) (CCM)

The study of the origin and evolution of the universe encompasses many of the most fascinating questions in science. What is our place in the universe? How did everything in it get started, from galaxies and stars, to planets and people? And what does the future hold, for our star, and our universe? Recently, scientists have made remarkable advances in providing concrete answers to these profound questions. The new technologies of observational astronomy, with its ground- and space-based gamma-ray, X-ray, ultraviolet, infrared and radio telescopes, is truly producing a new golden age of discovery. This book presents the excitement of these new discoveries in the larger context of cosmic evolution. The distinguished contributors are leading researchers at the cutting edge of these fields, and they also excel in explaining these subjects to the broader public. They offer the latest insights into these rapidly advancing fields, covering the origin and evolution of the universe, the chemical elements, galaxies, the evolution of stars, planets, and biological life. Essential physical concepts are clearly and carefully explained at the introductory college level. Related concepts from chemistry, geology, and biology are organized and integrated into the discussions. An extensive glossary is provided, and mathematical detail has been deliberately kept simple, to make the chapters accessible to anyone with an appreciation of science. The result is stimulating exploration of the frontiers of modern science that will intrigue both amateurs and professionals.

At close inspection every galaxy appears to have its own individuality.A galaxy can be warped, lop-sided, doubly-nucleated, boxy or disky, ... in its own specific, peculiar way. Hence, for a complete description, galaxy taxonomy may ask for finer and finer classification schemes. However, for some applications it may be more fruitful to let details aside and focus on some global properties of galaxies. One is then seeking to measure just a few quantities for each galaxy, a minimum set of globalobservables that yet captures some essential aspect of these objects. One very successful example of this approach is offered by the scaling rela tions of galaxies, the subject of the international workshop held at ESO head quarters in Garching on November 19-21, 1996. Discovered in the late 1970's, the Tully-Fisher relation for the spirals and the Faber-Jackson relation, or its more recent version the Fundamental Plane, for ellipticals have now become flourishing fields of astronomical research in their own right, as well as being widely used tools for a broad range of astronomical investigations. The work shop was designed to address three key issues on galaxy scaling relations, i.e., their Origins, Evolution, and Applications in astronomy. The Origins of galaxy scaling relations still escape our full understanding.

The Structure and Evolution of Galaxies is a concise introduction to this fascinating subject providing the reader with the fundamentals in a clear and accessible style. This user-friendly text assumes some prerequisite knowledge of astronomy, with the necessary mathematics kept to a minimum. Beginning with an introduction to the existence of our own external galaxies, the book moves on to discuss how perceptions of galaxy development have changed over time. The three categories of galaxies are then discussed with later chapters considering their formation and evolution. The book concludes with an overview of both current developments in the field and considers the direction of future research. Clear and accessible introduction to this dynamic subject Introduces definitions of key terms and puts them in context Includes current research and future developments in the field Appendix of basic definitions to clarify key concepts An invaluable text for students of astronomy and physics
