Knocked-up Ebony Mamas . Wittgenstein said that the purpose of a popularization is to make people think they understand something they don't understand. What seems to be a common current of science popularizations is that they "explain" things in such a simplified way that the reader who actually wants to get down to brass tacks is completely mystified. Einstein's book on relativity is a case in point, as is this book in which the candid reader is informed that "Objects at rest tend to remain at rest, therefore heavier objects will fall faster in a gravitational field." Got that? If so, maybe you can explain it to me. Listen, I know something about Physics. Back in the seventies I built a particle accelerator out of a blow drier and a box of Mike and Ikes.

One of the best books on tai chi . This book presents the 24 and 48 posture tai chi form. The 24 move form is good for busy people, but the 48 move form is even better because it combines movements from the 3 most popular styles of tai chi, Yang, Wu, and Chen, so the student gets some background in each. At 150 pages long in large paperback format, this book packs a lot of info between the covers. For example, I learned that in addition to the Wu style, there is also a W'u style, which I didn't know, although I've studied both Yang and Wu style tai chi. The author gives a brief introduction to tai chi in the first chapter, discussing basic concepts and information, then proceeds to some classical Taoist philosophy. He also tells some interesting stories about the founder and his sons, who had many adventures and exploits, and various stories and legends have grown up around them. Next there is a separate chapter on chi gung, a subject that has become almost a requirement for a tai chi book, I notice. However, most of the book is taken up by athe chapter showing the martial applications and the 48 move form. Dozens of applications are shown, and the photos are clear and easy to understand. I found this the most enjoyable part of the book, as there are still postures I don't know all applications for, such as snake creeps down, and the author presented one on that. There is a chapter on guidelines for tai chi practice that gives detailed instructions for how to use the different parts of the body, from the eyes to the feet in performing the form. I found this useful because sometimes I still forget some of the fine details of how to hold the body when I do the form. Finally, there are several appendices which provide a list of the 24 and 48 postures and their translations, a glossary on Chinese terms that is more complete than most, and a brief bibliography for further reading. The book is well written and easy to understand even when discussing some of the more abstract and esoteric principles. There are two mini-biographies of each other, two prefaces by two different masters, and a preface by the notable Dr. Yang Jwing Ming

The Great Falling Away . A more appropriate title for this book would have been: "Transformed Away From The Truth...The Liberalization of the Worldwide Church of God; The Remarkable Story Of A Church's Journey From the Religion OF Jesus to a Religion ABOUT Jesus". Love him or hate him...the lectures, broadcasts, published books and magazine articles of Herbert W. Armstrong brought many thousands of people all over the world to the knowledge and acceptance of Jesus Christ as personal saviour...many of whom had never even considered attending a church before! This was no pop culture 'plastic Jesus', but the Christ of the Bible...whose actual teachings would still be much in disfavor in today's supposedly 'enlightened' Evangelical world. Yet, the author of this book vainly tries to insist that the Worldwide Church of God under the direction of Armstrong was more hung up on the 'Law of Moses' and the 7th Day Sabbath, rather than the "grace" of Jesus...and thus relegated Him (Jesus) to background status behind God the Father, and Bible Prophecy. In 1976 the WCG published perhaps the best book written to date about the life, person and teachings of Jesus Christ, "The Real Jesus" by Garner Ted Armstrong who, at the time was a high ranking Minister in the denomination. This, along with all the other Christocentric books and articles published by Armstrong over the decades since 1927, are all strangely ignored...as if Armstrong himself, never gave Christ as much as a passing thought! Joseph Tkach Jr. goes on to largely bear 'false witness,' as it were, against the Church; its teachings; its mission; and its founder and late Pastor General H.W. Armstrong. He takes Armstrong to task over having the audacity to actually think that God would use him, to start a new era in the chronology of Church history....yet he himself mulls over the same thing, in his own role in the destruction of the denomination, which ironically he sees as a new beginning 'under grace'...whatever that means, since he's gone on to disfellowship entire congregations in various parts of the country...for continuing on in the traditional faith and worship practices, and for refusing to adopt his new 'tupperware party' style of pop-worship service. About the most interesting thing in the book, were the charts tracing all the breakaway conferences, or 'splinter groups' as he calls them...however, the biggest irony is that the largest breakaway group, "United Church of God" now has more members than the WCG under the Tkach regime! Another shortcoming of the book is the total lack of comment on, or concern for the victims of the Church's meltdown; the divided families; the fired long-time Ministers and other employees, and the total disruption of the Colleges. Perhaps the Church's new leaders need to write and sell books to make an income; since over 100,000 members picked up and left the organization since Tkach and Feazell took over the reins. Make no mistake about it...he (Tkach) has his fans, who view him as a 'liberator', while his detractors suspiciously view him as the possible end-time 'Man of Sin sitting in the seat of Moses', mentioned in Revelation! Christ did say "Ye will know them by their fruits..." Thus far the fruits of Tkach's leadership have resulted in a bitter harvest
