Book Description
With a clear writing style and matter-of-fact approach, this rigorous yet accessible introduction to quantum computing is designed for readers with a solid mathematical background but limited knowledge of physics and quantum mechanics. Using a methodical approach and an abundance of worked examples, this handbook delivers a thorough introduction to the quantum circuit model, including the mathematical formalism required for quantum computing.
Concentrates on the quantum circuit model to make complex subject matter more accessible. Provides a phenomenological introduction to quantum computing, encouraging readers to view the subject as a fundamentally new approach to computing. Detailed presentation of quantum algorithms demonstrates the logic behind the development of Deutsch’s problem, quantum Fourier transform, Shor’s factoring algorithm, Simon’s algorithm for phase estimation, and discrete logarithms evaluation problems.
For anyone interested in learning more about quantum computing.

Errata........2005-11-18
An errata for the book Approaching Quantum Computing has been available at http://www.cs.ucf.edu/~dcm since February 2004. Please contact the author (dcm@cs.ucf.edu) to signal any error you may find.
Filled with errors.......2005-11-18
There are a number of good books about quantum computing around. Unfortunately, because it has a number of errors, and because the explanations are not always clear, this is not one of them. I know somebody who, after reading this book's section on superdense coding and teleportation, ended up more confused than he started out. This is because not only is teleportation presented using a forest of bewildering 8x8 matrices (correct, but only useful if this is explained well), but the words accompanying these matrices are actually wrong. For example in superdense coding Alice is said to send Bob a quantum bit in a state described by a 4-dimensional vector. This vector actually describes the joint state of Alice and Bob's quantum bits, and there is no way to describe Alice's quantum bit alone. This is a very important distinction to make if you want to comprehend the material, and this book does not make it here. We also learn that in teleportation, "The transfer of quantum information appears to happen instantly, though Bob needs to first receive classical information regarding the result of Alice's measurement before validating his own result." I'm not even sure what this sentence is trying to say. What does validating mean in this context?
The definition of uniformity is wrong. The authors do not appear to understand the concepts behind this definition, or if they do, they are incapable of communicating these concepts to the reader.
In the factoring algorithm, the second condition in the definition of order of r modulo N is incorrect. First it has a 1 in the right-hand-side, and the authors meant to put a 0 there. Second, this condition does not belong in the correct mathematical definition of order. And finally, they don't need this condition since they don't seem to use it anywhere. To make matters worse, Figure 5.10, which illustrates the factorization process for 21, shows 1 times 11 being equal to 16.
To be fair to the authors, these errors have now been corrected in the errata, and I haven't looked at earlier chapters of the book, which may be better than the chapters I did look at.
a new topic in cs and math.......2005-10-03
In planning a course on quantum computing, an instructor would want to cover the significant highpoints in the subject: Shor's factoring algorithm, Grover's search algorithm, Deutsch's problem, the hidden subgroup problem. I for one found that this book does precisely that. Students will want an accessible and attractive presentation. This book is beautifully presented, nicely organized, and pedagogically presented with motivation, clear explanations, and well chosen exercises.
While the subject has a variety of facets, physics, math, computer science, this book emphasizes the last two. In a highly interdisciplinary subject, each author (or team of authors) must make selections. In selecting what to cover, the authors had the classroom and students in mind.
More precisely the subject here is presented in the form of quantum gates, channels, and circuits. Yet, quantum physics and the foundations are not neglected.
The graphic presentation (figures and diagrams) is done in a way to aid learning, and I expect that this book will be the preferred text in courses in the subject for some time to come.
Advanced undergraduates will be able to follow the logical progression of subjects. Several special features in the book help: Exercises, an extensive and instructive glossary, historical insight, motivation, appendices (including key math topics, e.g., modular arithmetic and Hadamard transforms which perhaps may not be widely known), and circuit diagrams illustrating at the same time matrix factorization and the complexity of circuits.
Contents: 1. History and background, 2. Rudiments of quantum physics as it is needed, 3. Qubits and computer science rewritten in the form of quantum gates, 4. The key quantum algorithms (Shor, Grover, Simon) and the highpoints in the subject, 5. Entanglement, decoherence, error-correcting codes, Bell, dense coding, EPR, reversible computation, thermodynamic entropy, and more.
Highly recommended!
Book Description
Courageous Souls explores the premise that we are all eternal souls who plan our lives, including our greatest challenges, prior to birth for purposes of spiritual growth. The book contains ten true stories of people who planned physical illness, having handicapped children, deafness, blindness, drug addiction, alcoholism, losing a loved one, and severe accidents. Because very different life challenges are often planned for similar reasons, readers who have not faced these specific challenges will nevertheless see themselves - and their motivations as a soul - in these stories. As readers come to realize that they themselves planned their lives, suffering that once seemed purposeless becomes imbued with deep meaning. Wisdom may be acquired in a more conscious manner; feelings of anger, guilt, blame, and victimization are replaced by acceptance, forgiveness, peace, and gratitude.

So that's why . . ........2007-10-08
If you ever want to get into the backside of your pre-birth planning of your life challenges, read Courageous Souls by Robert Schwartz. Want to know why you attract illness, accidents, birth defects? Want to know why you chose a life of alcoholism or drug addiction, or are around someone who has? Read this book. The stories, while may start out slow at first, are powerful and insightful. Just stick with them. Robert uses mediums who are able to access multiple guides at one time, and your primary guide and listen in on conversations between you and your soul group.
not credible.......2007-09-30
I got to p. 300 and started reading another book. I found this book painstakingly slow to read, the information provided by the mediums: farfetched, and the conclusions drawn by the author, hard to swallow. Often, when mediums are tired, their accuracy rate diminishes. I never heard of any of the mediums used in this book. Robert Schwartz makes everything so complicated when the subject matter is really quite easy to understand. The book just doesn't flow easily and it's not a page turner in my opinion. I'm a believer, but this book really is a waste of time and money. Read Journey of the Soul by Michael Newton, PhD. Instead of using mediums, he enters the superconsciousness of his clients and elicits information from them directly about their experiences on The Other Side.
An Empowering Way to Reframe Painful Challenges in Our Lives.......2007-09-17
It has been said that asking oneself the question, "Who was I before I was born?" can teach us the most about our true spiritual identity -- yet few of us have been so enlightened as to have heard the full reply. COURAGEOUS SOULS takes this starting point one step further by exploring just how we may have crafted our entire life around all of our life circumstances -- both the high and the low points.
What sets Robert Schwartz's book apart from other books about spirituality, reincarnation and the afterlife is his organized use of intuitive readings as companion pieces to accompany the various life stories he includes. These intuitive sessions provide a deep sense of interconnectedness and unconditional love shared in our lifetimes which we sometimes lose sight of, as well as insights into how we continue learning life lessons from one life to the next. The stories include descriptions of people who have experienced tremendous suffering who are greatly inspired and relieved to see an underlying sense of purpose and meaning to all they have gone through.
COURAGEOUS SOULS is an exceptional book for anyone interested in exploring the true nature of their spiritual identity, who is willing to keep an open mind regarding the value of some of the most painful challenges we humans face in our lives on Earth; this is highly recommended reading for anyone seeking to reframe and find deeper meaning from the painful challenges, setbacks or hardships in their lives.
Some of life's challenges explained........2007-09-06
.
Before I even finished reading this book, I ordered more and had them sent to my friends. This book is amazing.
Told through many soul journies, Robert Schwartz brought in the talents of true mediums who were able to discover decisions that these people made before they were born - again. He did not use just one medium, but several, and they are listed in the back of the book. The individuals who shared their stories are also listed with email addresses -- and if they are able and have the time they will answer your questions.
This book came to me at a time I really needed to be reminded of my own experiences through many lives and the time between our next life. The stories are beautiful because they are able to explain why certain tragedies happen to a person.
I highly recommend this book, especially to those with open and searching minds.
Why Human Challenges Exist!.......2007-08-28
Courageous Souls is highly recommended to anyone trying to understand the suffering, tragedy or loss that has caused them to question life, death and/or God. And who among us is not inflicted by such challenges and questions in our lifetime? In my eight years researching life after death, spirituality and life purpose, I have discovered no better explanation of why human challenges exist than what is so eloquently written in Robert Schwartz's book.

Book Description
Inspired by a desire to design a new pool for her own Long Island backyard, Kelly Klein sought out and put together the most arresting and iconic photographs of swimming pools in all their various forms to create this unique and stunning book. The photographs are as inspiring as they are moving, revealing an incredible wealth of styles and designs in climates and cultures across the globe, and evoking the sensations of rest and nostalgia, the clarity of water and light, the coexistence of coolness and warmth, and the insinuations of sex and romance that can bring such character to a swimming pool. Included are pools in all shapes, sizes, colors, and settings, from Tangiers and Miami to the ancient magnificence of Hadrian's Villa; from Coney Island to the Côte d'Azur; from the robber baron 1880s through the prosperous 1990s, and captured by great photographers such as Lartigue, Stieglitz, Munkacsi, Weston, Mapplethorpe, and Weber. Republished in its entirety from the original first edition of 1992, including 187 photographs and a note from Esther Williams, Pools is a classic of modern design photography and an inspiration to aesthetes and creative homeowners alike.
Customer Reviews:
Fell Short, Very Short.......2007-09-10
Kelly Klein explains that she was inspired to create a comprehensive design reference for those wanting to complement their own backyard with a swimming pool. While the book does provide dozens of interesting and beautiful photographs of pools, water and people, it provides little, if any, inspiration for those hoping to design their own oasis. There are dozens of books that offer better photographs and design ideas for modern backyard swimming pools. In addition, there are thousands of photographs on the internet that would offer more help than most of those shown in Klein's book.
If you are desperately looking for a coffee table book, you may find this one appealing. Personally I think there are dozens, if not hundreds, of better collections of photographs. Other than the quality of the paper, this pretentious volume wouldn't warrant a $12.00 price tag.
An elegant and soothing read.......2007-08-11
This book is like getting a massage for your eyes. Its photos range from anecdotal to iconic to escapist, and span several time periods and social classes. The foreword by (who else?) Esther Williams is an excellent treat. My coffee table would be bare without it.
Captures the art and majesty of the swimming pool in all it social and radiant beauty..........2007-07-20
Sensual, reflective, glimmering, surreal. The notion of the swimming pool means many things to many people. From the large public pool arenas from the turn of the century to the private, architectural masterpieces of the late 20th century, Kelly Klein's 'Pools' captures the art and majesty of the swimming pool in all it social and radiant beauty. Since it's original publication in 1992, Kelly Klein's 'Pools' (with a forward by Esther Williams) has been one of the most sought after large format photography books in the out-of-print world. Now, with this new long awaited edition by Rizzoli, the magical aura of the pool is captured again in both luscious and historical photographs from the likes of Jacques Henri Latique, Edward Weston, Herb Ritts, Robert Mapplethorpe, Greg Gorman, Bruce Weber and others. Pools from Beverly Hills to Europe to Japan to San Simeon's Hearst Castle are depicted in breathtaking spender spanning a full century of coverage in both black and white and color. For someone who didn't even have a pool at the time of the book's original publication, Klein has assembled a vast compendium of the scope of the manmade aquatic experience as both a physical pastime as well as an aesthetic window into the liquid life. As a summer treat or as a historical perspective, 'Pools' is a welcome refresher and certainly one of the best coffee table art books of the year. - BlogOnBooks
A long awaited re-release of a classic coffee table book........2007-06-27
I always regretted not buying the first edition of Kelly Klein's POOLS in 1992 and was thrilled to learn of this Rizzoli re-release in May 2007. It's one of the ultimate iconic coffee table books - famous pool photos by legendary photographers as well as photos of just plain gorgeous swimming pools around the world. Well worth the money and just looking at it makes you want to take a dip, plus the commentary by Esther Williams is a plus. And it looks fabulous on the coffee table! Would make a great gift too.
An awsome photographic book of pools around the world.......1999-05-19
I really enjoyed this book. There were very beautiful pictures of pools from all over the world. Every pool was an art piece in its self. I really enjoyed the pictures of the cascading pools that seemed to almost go to nowhere in particular. If you can get a copy of this book I highly recommend it for the photo or pool enthusiasts.

Book Description
Harbound. Oversized octavo. xi, 440 p. illus., 59 plates [Washington. "It was to Appius Claudius Crassus, statesman, financier, and even poet, with his colleague in the censorship, thatRome owed its first aqueduct . While not a new invention, since the system of conveying water from distant sources by artificial channels had been known for centuries in other lands, it was for the Romans a new departure, or better, a new application of their earlier discovery of the use and construction of underground channels for sewers "-From Introduction During her time in Rome, Van Deman firmly established the criteria for dating ancient Roman Building construction which still remains astandard. She was not just the first woman Roman field archaeologist. In her investigations of the fundamental problems of the chronology of building materials and methods of construction, she laid the foundations for serious study of Roman architecture. When her observations were confirmed, she decided to apply her method of identification to other buildings and constructions. The results of these studies were published in several articles. After this, she turned to a study of the RomanAqueducts, which had never gotten any detailed attention. Her ensuing studies and writings specializing in this field are a model of investigation, record, and interpretation.

A nice little time capsule of the period.......2007-05-17
A nice insightful look into the life of a working class umarried mother of the late victorian period who copes with her misfortune of falling in with the WRONG PERSON and struggles to rise from the situation towards her self redemption. Everyone can identify with this main character.
It is cold and unsentimental. Very Victorian in its writing and very very real in its view. Absolutely unflinching in its view.
I got this novel to give me insights into the period. I found more than I was looking for and am very very well pleased as will anybody who cares to sit down and read this delightful novel.
Good look for the student of history interested in Victorian England. A joy for anyone interested in the life of women. And a very good moral novel that anyone will enjoy reading.
An unflinching survey of poverty and survival.......2004-07-16
An unsentimental (nearly unemotional) survey of poverty’s crushing dehumanization. Born impoverished, the title character is nonetheless raised with a carefully defined sense of morality and self-respect. This is wrung out of her over years of economic exploitation and casual sadism by the moneyed class. By the end of the novel she’s accepting the most degrading misfortune as almost a birthright.
The Victorian writing requires careful reading. The paragraph where Esther has premarital sex is so opaque that it’s uncertain what exactly happened until later when the pregnancy is revealed. And certainly the word ‘pregnancy’ isn’t used (“Yes Ma’am, I’m 7 months gone”).
Finally a pet peeve about phonetically spelling dialects. Reading dialogue like " ‘e went ‘ome to see ‘is wife, but she locked ‘im out o’ the ‘ouse. " gets mighty tiresome.
First major English realist novel.......1998-12-09
George Moore was an Irish landowner who received his indoctrination into the world of art and literature in France. His encounter there with the realist movement led to the first three truly realistic (defined as against the prevailing moralism and/or melodrama of Victorian fiction) novels in English literature proper: A Modern Lover, A Mummer's Wife and Esther Waters.
Of the three, Esther Waters is the most fully developed and it is certainly the most engaging for a modern reader. In it, a woman has a child out of wedlock, and not only survives (through a variety of trials that are dispassionately but unflinchingly depicted) but in a manner of speaking prospers (Compare this for example with Elizabeth Gaskell's *Ruth*, written some 40+ years earlier).
A great read. An important milestone in the transition from moralism to realism in English fiction. An Irish writer who played an important role in the Irish literary renaissance in the early years of the 19th century.
Well worth the read.
Book Description
Jesus told the woman at the well that He was the living water. If she drank, she would never be thirsty again.
Christian women everywhere carry that living water inside them and are surrounded by parched, thirsty people. This book will help them learn how the Spirit can empower them to splash the living water of Jesus to thirsty people they meet every day.
Through refreshing stories, Scriptures, and encouraging words, the reader will be revived and restored and feel a new intimacy with God, who fills us up until we overflow into the lives of those around us. It's the most natural form of evangelism—simply sharing what God has done in your life.
