The organization and format is well thought out. The earliest chapters deal with time and coordinates which are used in the more complex problems such as computing planet positions later in the book.
Each concept is explained in straight forward language and conventional algebraic formulas are supplied. I found this especially useful for programmers using higher languages such as C,Pascal or Java. Then a step by step practical example is provided that is suitable for a scientific hand calculator. Duffett-Smith is careful about displaying units; a mindfield for most scientific calculations.
My only minor criticism is that some of the typos errors could leave a user quite frustrated. On pp108 I found the value of Tp=0.240850 gave the correct answer while the tabulated value is 0.240852. Similarly, I on page 129, after repeated checks, I got a value of 7.08...AU for Rho compared with the value of 8.13AU in the book. The text cites a 7.2AU value from the Astronomical Almanac.
Otherwise this is one neat addition to the bookshelf of any amateur astronomer of individual interested in astromical calculations.
Starting from the simple building blocks (converting your local time to Universal time), it progresses to more and more complex calculations, until finally at the end, you can calculate eclipses and planetary orbits. All the formulas needed for doing this are given in the book, and explained in great detail with many diagrams. All relevant astronomical data is also given. And for every calculation, a sample example is carried out with real numbers, which you can trace along with, so by the end of it you understanding is complete, practically as well as theoretically.
A must read for any astronomy buff. I highly recommend it. It produces the information age equivalent of that feeling of satisfaction you get when you build a telescope and look out onto the heavens yourself--without any intermediaries. Astronomy and stargazing are the activities which were the genesis of the scientific revolution, more than 6000 years ago. This book shows you just how its done.
Drucker's work has influenced my consulting work and writing for years. I invoke his concepts frequently in my recent book, Work Naked: Eight Essential Principles for Peak Performance in the Virtual Workplace, so I am pleased that he has produced another important reference for business leaders.
This new book provides an excellent sense of the evolution of his point-of-view and of the very nature of work over several decades. He is one of the few authorities with a broad, deep perspective and that is even more valuable in less than optimal economic conditions. As always, it is refreshing and rewarding to read his clear, insightful ideas -- a true master at work!
This is the condensation of: The New Realities (1988), Management, Tasks, Responsibilities, Practices (1974), Managing for the Future (1992), Management Challenges for the 21st Century (1999), Management in a Time of Great Change (1995), The Practice of Management (1954), The Frontiers of Management (1986), Innovation and Entrepreneurship (1985), The Effective Executive (1966), and Post-Capitalist Society (1993).
I have to admid one thing: THIS IS MY FIRST DRUCKER BOOK ;-).
For those like me who postpone the will to read DRUCKER as confution of where to start, start from here, and follow the other area of your interest.
This is a holistic approach of management from THE MAN himself. And i would not grade less than anything best possible.
If you already had druckers book, this is a good review of the past and reinforce back his view on management.
He has interesting view on the internet ;-).
Either you are a Drucker New Comers, or Druker Veteran, this book is for you.

The book is full of easy-to-follow writing that provides good information both for the workout and about our Marine Corps. With full and detailed walk-throughs of both enlisted and OCS physical training courses, the book covers just about anything that anyone considering the USMC would want to know.
The workout itself is clearly laid out with pictures of each exercise being executed with proper form and with schedules that work for beginners and advanced alike.
If you want a general information book about physical training in the USMC or if you just want a solid, easy, all-over body workout...you have GOT to look into this book.
Unfortunately, Peter Maas's story could be told about many large urban police departments. Make no mistake about it, corruption, bigotry, and racism are all a part of law enforcement. It was the case back in the 60's - 70's, and it is still the case today. Consequently, Peter Maas's story about "one good cop" fighting a sea of corruption is still relevant today.
The story drags at times. But, otherwise, it is quick reading. It is definitely a story that needs to be read. Hence, I recommend this book. Police corruption is still a current topic. But, more importantly, Serpico's story is one of hope. At least there is "one good cop" out there trying to make a difference. And, knowing this, has made a difference in the way I view law enforcement professionals. That is, they are not all bad.
Comparing his comments to the actions of present day politicians, I don't think there are many differences. Everyone does a little grafting and civil servants are still "civil servants." Understood?
As with any politician, Plunkitt "seen (his) opportunities and (he) took 'em." This is a must for anyone interested in any realm of politics.

As a parent myself, I will never forget what happened to little Dennis Jurgens.
