4.0 out of 5 stars
Good but marred by many errors, July 11 2010
By G. Smith - Published on Amazon.com
This review is from: Astrophysics is Easy!: An Introduction for the Amateur Astronomer (Paperback)
The book promises to present a treatment of astrophysics which can be understood at a reasonably deep level while keeping the mathematics in the background. To a large extent, the author succeeds in doing this. The main text has almost no mathematics, while for those who wish to go a little deeper into the subject matter, there are boxed paragraphs which explain the topic in more detail. All in all, this is a good book to read, but unfortunately there are many typographical mistakes, which can in some cases confuse the reader. For instance, in box 1.3 on p8, the word "distance" in the first line of the third paragraph from the end should read "luminosity". In Table 1.2 on p9, the very last entry in the right hand column should be 100,000,000 and not 10,000,000. On p19, the statement that temperature is proportional to temperature is incorrect. It is, as the author states a few lines above, proportional to the fourth power of temperature, which is not the same thing. Clearly the author is trying to simplify matters for the non-mathematical reader, but this is not license to make incorrect statements. Many of the coordinates given for various objects are incorrect. An observer using a goto telescope and the author's coordinates to point to the famous double-double in Lyra would end up with the telescope pointing deep into the southern hemisphere. Same comment about 61 Cygni, NGC 891 etc, etc.
If the author is contemplating a second edition, it should be thoroughly proof-read before publication. I would also suggest that footnotes, rather than end of chapter notes would be less disruptive when reading the book.
It is a pity that a book of such promise looks to have been produced in a rush. I still have no hesitation in recommending it, but the reader should not necessarily accept everything in it as correct.

Intended to help the amateur astronomer take a step into the physics of astronomy, Feb 16 2010

This is a great little book. Whenever I give a talk on my astrophysics research (in high energy cosmic rays and neutrinos) to the amateur astronomers, I mention this book as a good step for expanding their knowledge of the science underlying their hobby. Professional and amateur astronomy are a long distance apart, though many scientists got interested in science first from looking at the skies. This book helps bridge the gap somewhat.

Concise Introduction to Astrophysics, Aug 17 2008

Don't let the size of this book fool you. It is packed with useful information and I highly recommend it to anyone interested in learning more about what they see in the night sky. Each section of the book has example objects to view...I really like that aspect of this book.
Don't be concerned about too much technical/mathematical detail. The material is presented in a way that's "meaty" and concise which makes it easy to get the most out of it.
Prior to reading this book I read a college level astronomy text and several amateur astronomy books. I would say this is an important addition to any amateur astronomer's bookshelf. The material is up to date and well presented.
