The ability to visualize objects in an abstract subject like algebraic geometry boils down to, in the case of toric varieties, to a consideration of how to manipulate polytopes geometrically. A major portion of the book, if not all of it, is devoted to the computational geometry of polyhedra. Because it is an introductory book, some more advanced topics, such as Bayesian methods to find similarities between polyhedra, and neural network approaches to classifying polyhedral objects are not treated. Readers who need to do such things will be well-prepared for them after a study of this book. In addition, there are good exercises assigned at the end of each chapter, so the book could be used in the classroom. Some readers will however choose to use it as a reference source, and it would be a good one, for the author gives references to topics that he only touched upon in the book.
Some particular areas that were treated especially well were: 1. The discussion on data structures for surfaces of polyhedra. Although not very general, since he choose to deal with only triangulated polytopes, readers who need to be more general will have a good start in this discussion. 2. The discussion on volume overflow and how to deal with it using robust computation. 3. The discussion, albeit short, of the randomized incremental algorithm. 4. The treatment on the minimum spanning tree and Kruskal's algorithm. Communication network performance optimization is now a major application of this algorithm and others in graph theory, including the author's later discussion of Dijkstra's algorithm.

I work for a very large AeroSpace contractor in the Computer Security department. I needed a resource that I could get my hands on critical underlying OS information quickly. I found that in this book. It has already been a help in computer related investigations. I work both classified and unclassified networks. On the classified side of the house, this book has aided me in accrediting networks to insure data integrity and protection. I'm starting to see more and more upgrading of OS's. Per the NISPOM (National Industrial Security Program Operating Manual) when a classified system changes an OS or application that will "change" the security attributes of the system, it must be reaccredited. Again, I found great information in this book that talked about the changes between (for example) NT 4.0 and Win2K. As a result, I've required system owners to update their Security Plan and go through reaccredidation before actual implementation. Then, thanks to page 196, I was able to help them put together security audit tools.
Although I have not made it through cover to cover, I'm using the book a lot. It's definately a "Keeper".

Why? Because of the pictures! The softcover books don't have many pictures, if any at all, but this is LOADED with them, and quite a few are in color. It's absolutely outstanding, the way it is illustrated. Every single page just about is loaded with color photos of paintings, books, castles, portraits, you name it. They are all of excellent quality, though I'd have liked bigger ones, being the greedy person I am.
Extras seem to include a genealogy of the Counts of Champagne and a geographic guide to castles, listing extant ones country-by-country through Europe. There are explanatory notes at the end, a large bibliography, and photography credits. There is also a glossary and an index that looks adequate. This is a huge book, heavy and hard-covered, almost a coffee table book except for its vast wealth of information.
I'd say if you are interested in the Middle Ages, this would make a grand addition to your library -- and if you know someone who likes medieval history, this would make them a fantastic Christmas present.

Scientific evidence does not exist to prove things like the Atlanteans' crystal technology, their ability to travel through time and space, etc.. Since the author is a researcher he doesn't claim that scientific evidence exists where none does exist. But I don't see where he tries to disprove these fantastic but possibly true theories either.
This book discusses the Atlantis that Plato spoke of but by then Atlantis was much like the other races that existed around 1200 BC. This was a much different Atlantis than the one Cayce spoke of with its crystal technology, death rays, genetically engineered 'things', etc.. The islands of Atlantis sank over a period of thousands of years, not all at once if I understand the legends correctly.
I believe that proof of Atlantean technology does exist. It's been sitting on the Giza plateau for thousands of years. It's called 'the great pyramid'. In his book The Giza Power Plant Christopher Dunn proves that the great pyramid was a form of nuclear reactor. Dunn's book proves that the great pyramid was built by people who had god like powers and knowledge of time and space. It was Edgar Cayce in another incarnation as the high priest Ra Ta who built the great pyramid. The sacred geometry for building the great pyramid was given to Ra Ta by another god like being named Horus.
This idea is consistent with 'Edgar Cayce's Atlantis And Lemuria'. This book indicates that these god like beings from Atlantis and Lemuria became the mythical gods of later races such as the Incas and Myans. Those later races talk of 'gods' who came from the sea and taught them about new technologies, astronomy, etc.. Eventually most of this knowledge was lost as these civilizations de-volved to the point of like the Incas began the practice of human sacrifice.
There's a big part of the Atlantis story that's still enshrouded in mystery. All we have is a few statements from Cayce's psychic readings and a few archeological sites under water. You get glimpses of these mysterious topics when in the Cayce readings it refers to things like 'visitations of those from the outer spheres'. This would seem to imply that Atlantis was being visited by beings from other planets, other dimensions, etc..
This book offers a comparison between what happened to Atlantis and our modern world. Atlantis was destroyed by the greed of individuals. For them this was catastrophic because their greed could be transformed into energy by the terrible crystals.
The final paragraph of this book is:
"Everyone senses a crossroads just ahead. When we reach it, which example will we follow - Lemuria or Atlantis."
I would answer with a quote from a book called 'UFO Contact From Planet Iarga' which was supposedly communicated to someone by people from another planet called Iarga. The Iargans stated:
"The human race lives for the present since it really has no future."
The Iargans may mean that our human race doesn't have a long term future. Even if we last for another thousand years that's a relatively short time in relation to the universe.
I think most people would agree that many industries have a relatively short term view of using the earth's resources. Maybe somehow everyone knows that what the Iargans said is true.
The Iargans also said that sometimes when people see flying saucers those are our ancestors from Atlantis travelling through time to see us.
Joseph convincingly demonstrates that Cayce's perceptions of Atlantis and Lemuria were filled with abundant, credible images, although chronolgically inaccurate. They were like lucid dreams, in which the visual elements are clear, but the dreamer's sense of time is confused. None of this detracts in the least from Cayce's "life-readings". On the contrary, Joseph supplies abundant, newly discovered evidence confirming their astounding accuracy in almost everything, save a realistic time-scale. Joseph's book is the only one I've read that describes in detail the Lemurian-like ruins found underwater near Japan, including their photographs. His discussions of crystal-use in Atlantis and the Crystal Skull as an Atlantean artifact are the most thorough I've encountered.
As he points out, modern research shows that a continent did not sink below the Atlantic Ocean 12,000 years ago, as the old theorists insisted. That conclusion has been thoroughly out-dated and debunked by contemporary science. But a large ISLAND did indeed exist were Plato and Cayce said it did until the Bronze Age was brought to an abrupt end by a worldwide cataclysm. It is in that time-period, Joseph writes, that we must seek for Atlantis and Lemuria. The former civilization was characterized unmistakeably by Plato as a Bronze Age culture, dating back 3,200 years ago. Atlantis has thus been established in a proper and far more credidible historical context. Otherwise, to conceive of Atlantis as an Ice Age civilization is ludicrous.
Readers preferring to cling to obsolete notions of the past should not read Joseph's book. But anyone interested in learning the truth about Atlantis and Lemuria, and the stunning discoveries presently being made to establish their former existence, will find his presentation particularly exciting and revealing.

In contrast to the 200 page intro to AI, there is no primer on Java contained within this book. I feel this is OK since there are also many excellent books on Java. I only mention this to be complete in my review.
The real meat of this book is only ~165 pages (chapter 6 through 10). The agent examples are light, but adequate and I feel the concepts come across. Overall, I'm not sure I got my money's worth. I would have liked more discussion of various frameworks and maybe some examples of these. Implementations are lumped together in a hurried review in the last chapter.
If you already have some exposure to AI, you might consider a more advanced book. If you have never thought about AI, this book might serve as an introduction, but it is certainly not a comprehensive review.

Joseph Amato, Professor of Intellectual and Cultural History at a small college in southwestern Minnesota, tells an interesting, if familiar, tale. Dust was long defined by its occupation of the lowest position on the scale of the visible ('pollen' is the Latin word for 'dust'), and it symbolized insignificance and near-nothingness. Then came Western - now global - science. Dust became a multiform heap of material objects within a certain range of sizes ("With so much known about the invisible, dust can never again be ordinary," he writes), while at the same time ever more powerful instruments pushed ever further toward zero the notion of the infinitesimal. Meanwhile, civil authorities find themselves in a constant scramble to adapt to science's new insights into the implications for human well-being.
Prof. Amato is at his best in his survey of these societal responses to the news from the microcosm, and has interesting and upbeat things to say about the history of health, housekeeping, and hygiene. (He is much weaker on the scientific and intellectual side of things. I found particularly regrettable his neglect of Lovejoy's classic *The Great Chain of Being* - a work he cites in the notes but shows no sign of having assimilated.)
But the reader who arrives at the end of this brief volume is likely to be surprised at the author's take on the prospects of our increasing mastery of what is minute affecting our imaginative lives. In an essay written in the early twenties entitled "Subject-Matter of Poetry," Aldous Huxley expressed amazement that "The subject-matter of the new poetry remains the same as that of the old. The boundaries have not been extended. There would be real novelty in the new poetry if it had, for example, taken to itself any of the new ideas and astonishing facts with which the new science has endowed the modern world. There would be real novelty in it if it had worked out a satisfactory artistic method for dealing with abstractions. It has not." The concluding chapter of *Dust*, entitled "Who Will Tremble at These Marvels?" attempts to explain why not, and in doing so takes into a minor key what had till then seemed to be a work written in a major mode. This chapter, together with the touching ten-page memoir of his mother's relation to dust presented in an appendix, are the best things in the book.

The scenarios include dialogues between a teen and friends, teachers, parents or others who would play a role in the situation set forth. The authors later analyze how well the subjects of the dialogues handled the situations in the scenario. The book is very readible and the advice is genarally good, albeit not always in the greatest depth. As a parent and a school board of education member, I find the book useful and recommend it.
Riera and DiPrisco make it clear that there is no way to 'follow-the-dots' and come up with pat answers to the difficult subjects they tackle. Instead, this beautifully written book presents teens in their natural habitats. Real situations are depicted -- ones that anyone can identify with -- but rather than attempting to proscribe behavior, Riera and DiPrisco discuss each topic and scenario in an insightful section called Notes Home that will surely help parents bring a new slant to their thinking. It definitely opened my mind to new approaches.
I highly recommend this book to anyone with a teen -- or a soon-to-be teen. You won't be disappointed.

For some reason the editor didn't mention what was the content of the Nauvoo Expositor, or why it was so dangerous for Smith. Polygamy was also not addressed in any detail.
Smith comes off as an unreal man who always had the misfortune of being victimized by "bad" people.
Has history ever been this simple? Strange.
If you want an in depth study of the life of Joseph Smith, buy No Man Knows My History, 2nd Edition, by Brodie or for a fascinating psychological study, Inside the Mind of Joseph Smith by Robert D. Anderson. If you want a neutral evaluation of the Mormon church as a whole, I recommend Mormon America bye Richard and Joan Ostling. It you want a propaganda coffee table book, buy this one.
By the way, who is the guy who is pictured on the dustjacket? The cover pictures a handsome, all-American man, but open the book and look at actual period pictures and Smith is a round, odd-looking guy, not at all like the artwork pictured throughout the book.

It covers all of the the "classical" topics: convex hulls, line segment intersection, polygon triangulation, Voronoi diagrams, motion planning.
The mode of presentation -- supporting a discussion of the theories with implementable code -- is actually a bit refreshing. For comparison: Other books, when discussing the line segment intersection problem (ie: Given a set of line segments, find all of their intersection points) simply assume that computing the intersection of a pair of segments can be done in constant time. This is not an especially difficult problem, but the discussion seems more complete with a brief description of how this might be done. The same can be said about other primitive tests and operations in other algorithms.
Overall, this book can stand alone as an excellent introduction to computational geometry, but a serious student in the subject will want more: perhaps Preparata and Shamos or de Berg et. al.
