Cosmology: A Very Short Introduction

This is a fairly thin pocket-book which is easy to take on a trip. It is very informative. There are a few drawings, but illustrations are kept to a minimum. It covers the historical evolution of scientific thought on the nature of matter. It addresses the evolution of matter from the beginning of the universe to the present. It covers General Relativity and Special Relativity in a way that is easy to understand, without advanced mathmatics. It speculates on the contributions of String Theory. I enjoyed it. More people need to be informed about where we stand in scientific progress regarding the nature of the universe and the laws it follows.

This is a good general overview book. It's well written and covers the major topics of cosmology with good descriptions and easy language. If you are more scientifically inclined, than this book is probably too light to be of interest. However, if you an amature or just interested in the topic, this is a great overview. Easy read and very short.

I never would have expected a book with chapters discussing physics concepts to be enjoyable or understandable. Nor did I expect a book on cosmology to include that type of thing in the first place, which shows how little I knew about the topic before I read this. Needless to say, understanding the concepts author Peter Coles presents and actually wanting to know more about them was a pleasant surprise. This book flows smoothly from topic to topic, and the author does a good job of explaining things at a level detailed enough so you get some of the science behind things but not at a level so in depth that the average reader would be lost. A few helpful diagrams are also scattered about the book in places which would otherwise cause confusion. Where applicable, Coles gives brief introductions to various competing theories and points out both their strong and weak points. Despite being "a very short introduction," the book is very solid and thorough. The information presented is well organized and builds upon itself, so essential concepts are reinforced even as new ones are discussed. After finishing the text, I skimmed through the index and found that I actually remembered what most things listed there were. The only exceptions were names of people, and those aren't exactly essential to understanding the subject matter. I started this book without a completely accurate idea of what cosmology is, and I finished it knowing far more about it than I expected to. As such, I must say Coles was extremely successful in writing "a very short introduction" to cosmology, and I would definitely recommend this book to anyone interested in the subject.

Professor Coles' book on cosmology in the VSI series is a very good introduction to the subject. If you search for a first book on the subject, that's it (although you can also choose Stephen Hawking's Brief History of Time and the contents of these two books could complement with each other)! It provides an overview of the key concepts of cosmology in non-technical language while preserving room for deeper thought and exploration for those who are not satisfied with an introduction. In my opinion, Chapter 2 provides the best simplified exposition of Einstein's relativity and here and there the book shows very clear exposition of the Hubble's law with kept-to-minimum mathematical presentation which is comprehensible by the general reader without relevant training at all.Although it may be my own problem, I cannot quite get hold of the key concept of the Friedmann models. The models are first presented in Chapter 3 but they are often quoted in later chapters. Reading them all together, I fail to make a coherent understanding on the models.
