For example, at one point the authors are describing solitons (a term I had never heard before), states a theory that by generating an extra bit of energy we could put the universe out of the unstable equilibrium it currently exists in and cause it to "begin to boil." While this is all well and good, it makes vast assumptions that the authors neglect to mention. Most importantly it assumes that the universe is in an unstable equilibrium, a fact which although highly unlikely is not impossible. Secondly it assumes that the universe is completely clean of these bits of extra energy currently. They draw this parallel to an example of superheating water because without external particles to build upon no bubbles can form to release the steam. This is also true, but it is still impossible because it is impossible to have a perfect system like this. There are always going to be minute cracks in the pot, or imperfections in the water (fractal theory, covered earlier in the book, even states this!), and so while this might be theoretically possible it will not happen in any real world environment. The book has many other places like this where the authors conveniently leave out details that might weaken their arguments. I find this to make the book as a whole very frustrating to read, even if some of their points are valid.
Another reason that I find the book to be very frustrating is that everything is very sensationalized. At the beginning of the description of fractals the authors say that the first person to think of a fractal curve created "a panic among mathematicians that took some fifty years to resolve." I find it truly hard to believe that the entire mathematical community was pulling their collective hair for fifty years trying to explain this curve, but by phrasing it this way the authors make it seem like science as a whole does not want to accept new ideas because it would make them look bad. In reality though I think the scientific community is ready to accept anything that can be strongly proven theoretically, or experimentally (just look at relativity, or quantum).
Because of all of these failings I would not recommend this book. I am sure that there are many other better books about chaos theory that do an excellent job of describing it without disregarding the rest of science, or trying to place it in places where it does not necessarily belong.
My purpose to get the above knowledge is just in order to find the hidden order of financial market, and, of course, to make profit from the market. That's why I find this book is good to serve my purpose. It explained clearly on fractals, the relationship between chaos and order, and non-linearness.
I knew E. Peters has using fratals / Elloit Wave Theory to analyze financial market. Of course, it needs more intra-day data to try to find such fratals in a small scale period, e.g. in a 5-minute charts. But I guess that, such fractal are existing in the market, if you watching index movement everyday.
On another aspest, the technique of plotting data in a phase space is a tool to get the picture of financial market to me. This tools can be compared with weighted moving average, MACD, or other technical indicators. Though, phase space analysis is quite uneasy to a man without advanced mathematics. I'm quite sure such mathematical technique may apply to financial trading.
Besides, the idea of "quasi-periodic" is likely describing financial market. Though I got less knowledge from the book on this topic. It sounds like some ideas from William Gann, and other cyclist writings.
Hince, I'm benefitted from the book to enlighten new view point to see the world, and the market. I recommend any financial market practitioner to read this Chaos Theory guild and then reread some technical analysis classics, and reviewing their trading strategies. I believe that shall be worthy in one's trading life.
N.B. The picture 2.7 is missing (P.76), and there is some printing errors in its Chinese version which printed in 20.6.1997
The book is a stark attack on those the authors term reductionists -- those who seek answers in breaking the whole into ever smaller parts. The authors' pet writers are David Bohm, Lynn Margulis, and Llya Prigogine but they toss in another hundred ideas for irregular stepping stones to get where they are going. Where is that? They composed an evangelical message -- that man now has the tools and knowledge to step through Alice's Looking Glass into an entirely new and mystical perception of the whole. They see chaos as a source of future evolution and life.
I give the authors a high mark for original thought. Although using a hundred other science writers to frame their ideas, they direct the reader to go beyond existing theories and strike a path for the center of the turbulent mirror. The diagrams and illustrations also were very helpful. They pictured the brain as a strange attractor, with thought arbitrating between the two realms of order and chaos. My favorite metaphor was the slime mold which, when food gets scarce, merges from being a collection of individual cells to a collective entity moving across the forest floor. This was to show an example of quantum phase locking which "could provide a bridge joining classical, nonlinear reality with linear, quantum reality" (P. 188). Great Two Thousand year Philosophy.

Professional JSP is one way to get up to speed. Like many of the books published by Wrox Press, Professional JSP covers a specific technology in-depth, as well as the various ancillary topics relating to it such as databases, servlets, and XML. While not every developer will need every web technology covered by the book (and there are many), the book works both as a tutorial to cover the basics and a reference for technologies that you may encounter later.
Professional JSP starts by covering the basics of Java Server Pages, and how they relate to other web technologies. Embedded in HTML pages, JSP provides an easy mechanism for creating interactive web interfaces that draws on server-side components, known as Enterprise JavaBeans. While the presentation logic is written in JSP, the processing occurs within these JavaBean components. The book takes a balanced approach, covering both JSP and its syntax, as well as how to write and interact with JavaBeans to perform useful tasks, like accessing databases through JDBC and using other Java technologies. However, if you've read other Wrox titles, you may find there is some overlap in the topics covered.
One of the nice things about Professional JSP is that, in addition to covering theory, it goes further and examines practical applications of JSP, and issues for programmers like security and debugging. Like other titles in the Professional series, there are case studies of real projects using JSP and related technologies. My favorite would have to be the case study on porting Active Server Pages to JSP -- something that is extremely important for developers with "legacy" web systems. On the whole, Professional JSP is an excellent book for web developers wanting to get up to speed with Java Server Pages, web development, and Enterprise JavaBeans. However, developers with less of a web presentation focus and more of back-end server view may also want to consider the excellent Professional Java Server Programming title, which also covers JSP. -- David Reilly, reviewed for the Java Coffee Break
The book consists of 20 chapters. The first 12 chapters discuss the various salient aspects of JSP and the rest ( about two third of the whole book) is devoted to case studies.
A. THE BOOK'S STRENGTH:
By adopting Tomcat as its main testing software, the editors of "Professional JSP" have assured that most of the code examples will work. This is a big improvement over the past wrox books.
There are some excellent chapters in the first part. The discussion on session tracking is a real gem although the author failed to make a showcase of the code examples. The chapter on JSP Architecture contains some of the clearest explaination on the techniques of redirecting, forwarding and requestdispatcher. The chapter on customtags is equally very well done. But my favorite is the chapter on Global Settings, the idea is so practical. I also like the idea of emphasizing the importance of authentication which showed in many chapters of the book.
The case studies will serve as an excellent reference. Its coverage ranges from (1) the front end of an insurance company (2) a good pictures website which use JSP to publish its data (3) Security with JNDI (4) a online store using LDAP and JSP (5) J@EE, EIBs and Customtags (6) Multimedia and JSP (7) Weather website with JSP, XSLT and WAP (8) Porting ASP to JSP.
2. BOOK'S WEAKNESS:
The book is a combined effort of many authours and its unevenness showed. The first three chapters to introduce to JSP are out of place and a real waste. The chapter on Dynamic GUIs is a great idea which turned into a joke: after showing the general diea how to do it, the author sent readers to his website to learn the rest(?). And the chapter on JDBC connectivity and Pooling is a big disappointment: most of the chapter devoted to get connection, create databse,editing it and make query; and the rest the author explained how to use his own pool manager package, PoolMan. This wouldn't be too bad if PoolMan worked, with Tomcat.
The richness of the case studies is also its weakness. Unless you are experienced and have the facilities, you can't test them all. These techniques become obsolete pretty quick.
Probably the strongest objection to the book is its price. Buy it for your company and share with your colleague.
After the JSP fundamentals are out of the way (which I am sure any JSP newcomer will appreciate and can benefit from), the book picks up pace with discussion on JDBC connection pooling, and the best practice for data access from JSP. Then comes the chapter on custom tags. My favorite chapters are the ones on debugging JSP's and implementing the MVC design pattern in JSP/servlets.
The case studies are very comprehensive and closely correlated to the earlier chapters. In one case study the design methodology is clearly explained with UML diagrams, which are very helpful to someone who is currently architecting an enterprise Java Web application. Other case studies cover such a wide area of topics such as JSP in combination with LDAP, EJB, XSL, and WAP.
For ASP developers, this books has two enormously useful chapters to get them started on JSP right away. One is a case study showing how to port an ASP app to JSP, and the other compares and contrasts the object model and syntax between ASP and JSP.
Having said all the above, this book does suffer from certain weaknesses. One is typical of any multi-author book, i.e., repeat of the same topic in different chapters. This is the case with JDBC, which shows up in both chapters 4 and 7. Another problem is the lack of the use of a standard servlet/JSP container, which will help new users to run all samples under the same software setting (although there is an appendix on setting up Tomcat server). Finally, a few chapters seem to be out of place in term of the logic flow of concept, such as the ones on dynamic GUI's and JNDI.
Finally, this book is still thin on heavy-duty J2EE topics, such as EJB, distributed transactions, message service, and interoperability with CORBA. This is why I consider it as an intermediate level book, not an advanced one. Hopefully we will see another Wrox book in the near future that addresses some of these issues.
Now, I don't want to give away what happened in Hell because that's why most people buy this book, but just let me say, like another reviewer who has posted on another site, the Hell material really is a bit like Star Wars, injected the opposite way. Like a little peeping chick, newly hatched from his egg into the realm of death, Christ does not know who his Daddy is and why he's there. He thinks Satan is his Daddy and is pulled over to the dark side. That's all I'll tell you except, at one point, Jesus is moved to calling Satan a 'bastard.'
The Satan in this book is quite plastic. He's a cardboard villain. And the demons are described to death, into a certain flatness of character. This one had leather wings and that one had a hide like an alligator--point is, he'd have done much better allowing the reader to fill in the blank with whatever is most repugnant or awful to them.
One last thing: Hell is eternal darkness. Why have the sun rise over the lake of fire?
