### ⭐⭐⭐⭐⭐ AND AN EXCELLENT BOOK IT IS !!!
*by B***A on July 6, 2016*

I've always had an interest in cosmology. I remember as a college student in the 1960's being acquainted with the two competing theories: the Steady State Theory of Continuous Creation (championed by Fred Hoyle) and the Big Bang Theory (championed by George Gamow). At that time I remember being excited by the data coming in from the Cosmic Background Radiation whose 3 degree Kelvin black-body radiation supported the Big Bang. Astrophysics has been my passion since!A few months ago I worked thru Andrew Liddle's excellent little (no pun intended) book entitled AN INTRODUCTION TO MODERN COSMOLOGY (3RD ED). As a follow-up I took on this book, RELATIVITY, GRAVITATION, AND COSMOLOGY which was recommended as a next step by Liddle's book. And an excellent book it is!Unlike some other technical books I've worked thru, I ran across no errors in anything in this book! The material is presented logically interspersed with "exercises" for the reader to try, to check for your own understanding. I tried every exercise and was able to solve almost all of them on my own. All of the answers are given in the back of the book along with their solutions if you need to see them!The first 2 chapters review Special Relativity thru the concept of Four-Vectors.Ch 3 introduces the math of 3 dimensional Riemann curved space giving line elements and matrices. It also introduces the ideas of parallel transport, connection coefficients, geodesic equations, the Riemann Tensor, and the curvature of spacetime. I was not acquainted with this type of thing before so it was slow-going. If you like working with indices you'll have a great time with this chapter!Ch 4 deals with introductory principles of General Relativity and gravitation. Covariant differentiation, the energy-momentum tensor relating to regions of dust, ideal fluids, radiation along with the Einstein Tensor and Einstein Field Equations are presented. Dark energy: pressure and density are also described.Ch 5 presents Schwarzchild Spacetime which deals with the mass causing gravitation as a simple, spherical, non-rotating symmetrical body. The Schwarzchild metric is derived and properties of Schwarzschild spacetime are discussed.Ch 6 deals with Black Holes. First the non-rotating kind, then the rotating kind. Parts of this chapter I found difficult. Some of the items such as the line element for the rotating black hole are so complicated, the author states the derivation is not shown in the book since it is too complicated.I found Ch 7 dealing with Testing General Relativity very interesting. The book does not show most of the derivations of key formulas again, since they are too complex for this book, but formulas are given along with examples for:1. The precession of the perihelion of Mercury.2. The deflection of light passing a massive body like the sun.3. Gravitational redshift and time delay.4. Geodesic precession.5. Gravitational lensing.Gravitational waves are discussed although they were not yet discovered as of 2010 when this book was written. Today (2016) they have been, so the book needs an update.Ch 8 deals with Relativistic Cosmology. It gets into the expanding universe, the Robertson-Walker Metric, Hubble's law, curvature of the universe, the Friedmann and Fluid equations. Solutions to the Friedmann equations are given with cosmological models to work thru.In conclusion, RELATIVITY, GRAVITATION, AND COSMOLOGY by Lanbourne was an excellent book for me. I enjoyed it. Some of the math was a bit of a stretch for me but I felt I was able to comprehend most of it. My plans are now to work thru a book recommended as a follow-up entitled OBSERVATIONAL COSMOLOGY from the same publisher.

### ⭐⭐⭐⭐ Decent shape!
*by A***R on March 10, 2020*

This product was great. It was highlighted a bit more than expected but overall good shape.

### ⭐⭐⭐⭐⭐ Mathematics AND Colored Illustrations?  I Must Be Dreaming
*by C***S on October 5, 2011*

But no, it's true.Ok, folks, let's be candid. Most of you are trying to teach yourselves this stuff. You've made it through quantum mechanics, you get Special Relativity well enough, but General Relativity is an impenetrable barrier. Hartle and Wall are hard, Misner Thorne & Wheeler is terrifying.This is the book you want. The math is clearly presented and the many diagrams and enormously helpful. Each chapter has a summary to prepare you for what follows.Highly recommended.
