In the Preface to this 2nd edition the reader is advised that this textbook was written assuming the reader has a good background in electrodynamics, statistical mechanics, classical dynamics, and quantum physics. Also assumed was a very good background in integral and differential calculus. I found this to be the case!Chapters included are:CH 1- Introduction of standard units in astronomy including Planck scale units of length, mass, time, energy, and temperature.CH 2- Fundamental Observations on which modern cosmology is based including ideas regarding the universe being isotropic and homogeneous, redshift, Hubble's Law, scale factor and the Cosmic Microwave Background. I found this all nicely explained.CH 3- Both Newton's and Einstein's way of viewing the universe including the ideas about curvature, the Robertson-Walker Metric and how scale factors and redshift relate are covered. Once again I found all of this nicely explained.CH 4- Cosmic Dynamics including a very brief description of Einstein's Field Equation is covered. Also included was a derivation of the famous Friedmann Equation along with equations for Critical Density, Density Parameter, Fluid and Acceleration Equations, Equations of State, and the Cosmological Constant. Again, I found all of this explained very nicely and could follow all the derivations.CH 5- A very important chapter on Model Universes with the Friedmann Equation applied to various types of universes: Empty Universes, Single Component Universes: Flat, Matter only, Radiation only, deSitter Universes (flat with cosmological constant-Lambda). The chapter then became more complex with Multiple-component Universes: Matter/Curvature, Matter/Lambda, Matter/Curvature/Lambda, Radiation/Matter, and our current model: Flat/Radiation/Matter/Lambda. I really enjoyed working thru all the derivations from one equation to another in this interesting chapter.CH 6- Measuring Cosmological Parameters dealt with scale factors, measuring distances using Luminosity and Angular-Diameter, and Standard Candles all in a very mathematical way. I loved the mathematical descriptions and derivations.CH 7- Dark Matter. A nice mathematical description showing evidence for dark matter in galaxies and galactic clusters and gravitational lensing.Ch 8- The Cosmic Microwave Background, its history, and explanation using the Hot Big Bang model. This chapter became quite complex in describing the possible epochs since the initial Big Bang that would explain what we now observe. This was the first chapter where I got lost in the highly detailed mathematics but could still follow the general idea of what was being described.CH 9- Nucleosynthesis in the Early Universe. This also was a very complex chapter with a fairly detailed analysis of the nuclear reactions thought to have taken place resulting in the element ratios we observe today. My difficulty understanding it was probably due to my limited background in nuclear physics.CH 10,11,12 dealing with Inflation, Gravitational Instability, and Baryonic Matter's role in Structural Formation were highly mathematical and a bit beyond my reach. I probably would have done much better if these chapters were presented by a teacher in a live classroom rather than being tackled as a self-study by myself.Each chapter is also followed by a set of very challenging problems. I was able to solve many of them in the first half of the book but had greater difficulty in the later chapters.In short, the book lives up to its claim as geared toward the upper level student with a rigorous background in mathematics and physics.
I think I needed a couple of prerequisites before I jumped into this. Also, I read it on an iPad using the kindle app and the equations were way too tiny to read. This is. Recurring problem on tech books on kindle devices and on the kindle app for iOS devices. It’s not too bad on a pc, but it’s terrible on portable devices
Good book on introductory Cosmology. The book explains ideas pretty well, but there were a few ideas that were explained better elsewhere. If you use this book, I recommend also watching Leonard Susskind's lectures at Stanford on Youtube to get a better grasp of the material; the videos align well with the chapters in the book.
Ryden is an engaging writer and I found her explanations illuminating. This book was my first introduction to cosmology as a college junior and I really enjoyed it. The picture of cosmology that she presents is well organized and you'll feel like you see how the pieces fit together by the end.
good book
I'll briefly review two separate components, the shipping, and the material itself.Shipping: The book came extremely quickly, but have some minor damage on the front edges of the book and some minor cracking damage on the spine. Keep in mind this is the same kind of damage I would expect my own book to take after the first two weeks of use if actively carrying it to campus for studying. I'll only drop one star for it because by the third time I opened the book I no longer noticed it until I wrote this review.Material: The author is clear, easy to understand, and develops the readers intuition rather than emphasizing mathematical perfection while still delivering a sizable mathematical footprint . As an introductory course text aimed at the advanced undergraduate I'd have to say even at graduate level I still find this book provides a challenge. It is not the easiest book and it is not the most challenging. If you need background on concepts like luminosity or flux density then you should look at a book such as the Cosmic Perspective which is a true introduction to astronomy. If you want something more challenging, or find yourself capable of very high level reasoning then Dr. Weinberg's text book on cosmology and gravitation would be more suitable.
Great read, I highly recommend this for the novice who is interested in cosmology and willing to put in a modicum of effort.
Decent introductory cosmology text. Suitable problems, addresses all the main themes. More general relativity might have been a nice touch, but this was good.
