Valuable book for workers in the field of phase unwrapping, August 12, 2000
This book is a very specialized book and is of little interest to most readers, but for readers working in the field of phase unwrapping this book is a must. This book gives methods of solving phase unwrapping problems. Four pathfollowing and four minimumnorm techniques are described. A detailed analysis is presented for each algorithm. The distinctive feature of each algorithm is given and the algorithms are ranked in terms of their execution times, memory requirements, and successes and failures on the phase unwrapping examples. Guidelines are given for deciding which algorithm applies to a given problem. A suite of C language programs and routines comprising over 6000 lines of source code that implement the ideas and algorithms discussed in the book, and data sets, can be downloaded from the Wiley FTP site.

The book is a must for readers interested in adaptive optics, June 24, 2000
The book does an excellent job of describing the basic principles and the practice of adaptive optics for astronomical applications. The author was a pioneer in adaptive optics and in the 1970s he built the first system capable of compensating a large astronomical telescope at visible wavelengths. The book gives a good history of adaptive optics including an excellent bibliography. Wavefront sensors, correctors, laser beacons, and wavefront reconstruction and control systems are described. Current adaptive optics programs are described and future prospects are discussed. I had the good fortune of working with the author at the time the first adaptive optics system was built and the author conveys in this book the excitement we felt about adaptive optics at that time. While the book is very specialized and technical, and the number of readers who will enjoy the book is limited, if you are interested in adaptive optics the reading of this book is a must.

Superb book for explaining online option trading, May 29, 2000
The book is clearly written and it solved many of the mysteries I had concerning trading options. An excellent feature of the book is that it gives the addresses of many online sources for stock or option information.

Great book for everyone who uses Mathematica, February 19, 2000
Two years ago I swallowed my pride and I purchased an earlier version of this book, "The Beginners Guide to Mathematica, Version 3". I say I swallowed my pride because I had been using Mathematica since 1989 and I did not think I needed to buy a beginner's guide. However, I did buy the book and it was great. While I was not a beginner, the book taught me a lot of neat things that perhaps I should have known, but didn't. When I saw Version 4 of the book was available I purchased it immediately. It is great. Much of the material is a repeat of the material in Version 3, but there are new chapters covering subjects such as importing and exporting data, image processing, and realtime graphics. The book is clearly written and the authors' humor is delightful. Hopefully, the electronic version of the book will soon be available. I recommend the book to everyone who uses Mathematica.
