Book Description
Benoit Mandelbrot discovered what is now called the M-Set in the early seventies and coined the term ‘fractal’ to describe the geometry behind it. The power and the beauty of fractals were only capable of being seen with the advent of computers, which become psychedelic windows on the infinite when using simple fractal equations.
In 1992 Nigel Lesmoir-Gordon made the TV documentary, The Colors of Infinity about the Mandelbrot Set and fractals, which has since been seen right round the world. Nigel’s enthusiasm brought together a dream team of contributors for the film who all now contribute to the book tracking how fractals have developed since the film was made. Sir Arthur C Clarke presented the film and in the book gives a lucidly simple account of the mathematics of the M-Set. Benoit Mandelbrot, the Belgian mathematician explains how it began. Professor Michael Barnsley, the computer graphics researcher who developed fractal image compression technology, explains the applications of the breakthroughs. Professor Ian Stewart, author of Does God Play Dice? adds his insights into the beautifully simple equation that gives birth to fractals.
Two of the most interesting applications of fractal geometry, reflected by the two new contributors to the book, are to the Internet and to the Stock Market. Dr Gary Flake, Chief Technology Officer at Overture, the leading provider of commercial search on the Internet and just taken over by Yahoo for 1.6 billion dollars, discusses the profoundly fractal nature of the Web in his article: The Self-ish Web. Robert Prechter Jr is President of Elliott Wave International, Inc. and founder of the Socionomics Institute. His latest title is Socionomics: The Science of History and Social Prediction (2003). He writes about how fractals can help us understand the oscillations of stock markets.
In the back of the book is a DVD of the original documentary with soundtrack by David Gilmour of Pink Floyd PLUS a 30-minute fractal animation to the music of members of Quintessence.

Amazing!.......2007-08-13
The book and the DVD are truly amazing and beautiful. It has introduced me to a wonderful world which is a marriage of art and mathematics. The price is almost too low for such a masterpiece.
The Colours of Enlightenment.......2007-03-09
Depending upon one's education, it is possible to gain either an art appreciation of the fractal geometry of the Mandelbott Set or a realization of how all life is ordered and the universe structured. Life most certainly would exist somewhere out there and it would resemble what we have here on Earth. While viewing it, I felt that this was at least fifty percent of the riddle of the universe explained in at least its basis. The other fifty percent would be what Stephen Hawkin called the other formulae that will reverse this one. He hopes we will find this one before it begins to act in its turn. That would mark the collapse of the universe and he seems to think that we might prevent that. But the collapse may be inevitable and part of the eternal operation of two formulae.
The Mystery remains; was this ordered and if so, by whom or what? We may never know, but for this devastating mystery, we have David Gilmour's compelling score to propel us along through an eternal race toward infinity.
My only complaint is that the film needs re-mastering so that the fractal geometry can be expressed better. Ironic that the documentary that defines the detail of the universe is so fuzzy! Also, there is a second section of fractal art expression on the DVD that will only play on a computer. That ought to be fixed. I think it is fitting that Arthur C. Clarke is the narrator for this film, so I hope this original can be cleaned up and not trashed for an updated version with all new presentation and cast.
This documentary should be shown in all high-school science classes. In fact, I think it ought to be shown to everyone regardless of partticipation in science curriculum because it also assists the refinement of questions like evolution and religion.
Amazing Fractals.......2007-01-12
What an illuminating, thought provoking book and dvd! I have watched it several times and each time it has opened my eyes more to the amazing possibilities in almost every aspect of our existance here on earth. And then who doesn't like David Gilmour's music ?
A great way to discover the colours of infinity.......2007-01-05
Just a perfect combination of top-level science outreach with the
fantastic music of David Gilmour.
It's a journey into the wonders of the fractal geometry explained in
a clear and easy-to-follow way.

Fractal Visions.......2006-12-04
Fractals were just hitting the popular consciousness when I was in high school. I remember a flurry of pop science books that came out around that time, all of which presented the wonderful fractal images, while nevertheless dancing quite vaguely around the underlying ideas. The questions these mushheaded books immediately provoked in me (i.e. "what does 'self-similar' actually MEAN?" and "is complexity an objective quality or in the eye of the beholder?) were left totally unanswered. In my high school, these books (and the fractal posters, key-chains, videos, water-pipes...) commanded the attention of an intellectually philistine (and usually highly-intoxicated) crowd. People who use "party" as a verb. This "whoa dude-it's a fractal" factor was so powerful that it left the whole topic kind of disreputable in my book...until now.
This,too, is a "pop" science book, after a fashion, but unlike those other fractal books, the authors here refuse to dumb the subject down to a mere collection of pretty pictures. There is enough detail here to permit a diligent reader to truly understand the logic behind fractal geometry. If you can grasp the math, the basics are here. If, like me, you are a "liberal arts" type, the concepts are also explained in precise English.
The content of the video is similarly excellent. The interviews with Benoit Mandelbrot and Stephen Hawking are very cool indeed, but my favorite part is when Arthur C. Clarke states that, while he doesn't know about this PERSONALLY, "the ingestion of certain illegal substances produces fractal visions." Clad in his trademark blue utility shirt, and with a perfectly straight face, Clarke goes on to note the similarity between the words "Mandelbrot" and "Mandala." (Whoa, dude!)
Unfortunately, the video itself (i.e. formally, visually) is pretty dated. It seems to have been made for VHS, and has not been cleaned up for the DVD release at all. The colors are bled, and the titles look like they were made on a Commodore 64. The fractal images are quite low-resolution, which is unfortunate, since fractals are one topic for which high resolution would seem particularly essential. (Then again, NO level of resolution would really be sufficient.) This video is just begging to be remastered. With contemporary high-def video and computer technology it would be absolutely jaw-dropping. Still, this is totally worth it.

A Quick and Handy Guide to Transactions.......2007-02-14
This book concentrates on the transactions you make in the Financial Accounting subset within SAP R/3. There have been several books on setting up the SAP system. This is the first I've seen on understanding just what happens when you make an entry into the system. This includes entries into: General Leder, Accounts Payable, Accounts Receivable, and Asset Accounting.
The layout of this book is by individual transaction organized into five sections. This allows the reader to quickly find what he needs to know about any individual transaction. Example: If a vendor issues you a credit memo you need to make an entry into accounts payable that will reduce the amount you owe him. Under AP you will find a transaction: 'Post Vendor Credit Memo' with the transaction code of FB65. This leads you to page 157, where there is a complete description of this transaction including screen shots, what needs to be entered, what information gets entered by default, and various other information.
The SAP system is so big, and so complex that all possible transactions are not included, but instead the book covers those transactions that will be used day in and day out. This information is contained in other places, but in this book it is organized for quick and handy reference.
Book Description
"Ordinarily, events that change our path are impersonal affairs, and yet extremely personal. My teacher, don Juan Matsus, said this is guiding me as his apprentice to collect what I considered to be the memorable events of my life…. Don Juan described the total goal of the shamanistic knowledge that he handled as the preparation for facing the definitive journey: the journey that every human being has to take at the end of his life. He said that what modern man referred to vaguely as life after death was, for those shamans, a concrete region filled to capacity with practical affairs of a different order than the practical affairs of daily life, yet bearing a similar functional practicality. Don Juan considered that to collect the memorable in their lives was, for shamans, the preparation for their entrance into that concrete region, which they called the active side of infinity."
In this book written immediately before his death, anthropologist and shaman Carlos Castaneda gives us his most autobiographical and intimately revealing work ever, the fruit of a lifetime of experience and perhaps the most moving volume in his oeuvre.
Customer Reviews:
To Carlos, with gratitude.......2007-06-22
Carlos Castaneda was one of the most controversial writers of the twentieth century. Some in academia branded him a fraud for claiming his stories were biographical rather than fiction, while lauding him as a great novelist for exposing a mass audience to otherwise inaccessible philosophical abstractions they claimed were largely plagiarized. Each of his works is a piece of a larger puzzle, which makes it impossible to critique any one book without addressing the larger context into which it fits.
His first two books, "Teachings of Don Juan" and "A Separate Reality" describe experiences induced by ingesting psychotropic hallucinogenics prepared by a Yaqui Indian shaman from Sonora, Mexico he called don Juan Matus, and accounted for his becoming a guru to a generation seeking short cuts to spiritual enlightenment, as well as his lifelong interest in the relationship between perception and reality, a theme now explored in many popular books on consciousness and quantum physics. Unfortunately, these books remain his best selling works, in spite of Castaneda refuting their importance in his later works. Readers would be best served to skip these and avoid the risk of being turned off to Castaneda and missing the more stimulating works that followed.
His third and fourth works were "Journey to Ixtlan" and "Tales of Power." In Ixtlan he admits to over-estimating the value of his drug experiences, which caused him to overlook the more profound teachings of don Juan which became the focus of future writings. What emerges is a spiritual discipline dating back to the Pre-Colombian Toltec sorcerers of Latin America, culminating with don Juan's departure from our world, effectively ending Castaneda's direct affiliation.
In his fifth and sixth works "Second Ring of Power" and "Eagles Gift" Castaneda suffers strange flashbacks of what seem to be memory fragments of events he is unable to fit into any logical time sequence. In his seventh and eighth works, "Fire From Within" and "Power of Silence," Castaneda succeeds in reconstructing his lost memories, which derive from teachings previously administered by don Juan while Castaneda was in a "heightened" state of awareness.
In books nine and ten, "Art of Dreaming" and "Active Side of Infinity," Castaneda focuses on what he describes as inorganic predators from another dimension, some having the power to imprison humanity in "ordinary reality" so they can feed on the dark emotional energies we produce when succumbing to the negative thoughts they insert into our minds.
In later years several seemingly substantiating works appeared by two of Castaneda's female apprentices, Taisha Abelar and Florinda Donner-Grau. In addition, two scathing exposés were also published by two of his ex-wives. The first, "Magical Journey with Carlos Castaneda" by first wife, Margaret Runyon, offers little corroboration, since her marriage pre-dates the time when the bulk of Castaneda's adventures were claimed to have occurred. While steadfast that Castaneda was a sorcerer, she doubts the existence of don Juan, even claiming authorship of many of the concepts Castaneda ascribed to him.
The second, and more credible work, is "Sorcerer's Apprentice," by well-known writer Amy Wallace, daughter of the late best selling novelist Irving Wallace. Here again, we find little corroboration since the time of the events she describes is well after the period when Castaneda's relationship with don Juan is alleged to occur. What the book does provide is a troubling look inside Castaneda's final years, a picture of descent into what seems sexual addiction and possibly madness, leaving one to wonder if Castaneda was just one cup of cool-aid short of a Jonestown.
Many have asked why I put any stock whatsoever in Castaneda. A story from my autobiography, "The Vortex" may shed some light. A year before Castaneda published his first book I had an experience that would remain a mystery until Castaneda published "Power of Silence" twenty years later.
For a brief time, in my youth, I became a practicing Muslim, meticulously performing the complex prayer ritual five times a day. Then one night, sitting in my car, frustrated and complaining at not being able to find the address of my next sales appointment, something inside me snapped. It was as if some part of me had disconnected from my body and assumed control, lecturing me about my lack of discipline. A profound calm settled over me, rendering me simultaneously detached and engaged. For two days my sales figures soared. It was as if no one could say no to me. On the evening of the second day I decided to put my new state of being to the acid test by visiting my parents. Their behavior was so uncharacteristically supportive I hardly recognized them. It was enough to convince me that I was now living in an altered reality. But by the following morning I had returned to "normal." So distracting had this event been that I completely forgot to perform my Muslim prayers, and in fact, never did so again.
Twenty years later, in a chapter of "Power of Silence" entitled "Place of No Pity" Castaneda describes a very similar experience. In the aftermath of the event don Juan explains that humans are like televisions stuck on a channel called "self-preoccupation," lacking the energy to tune into any of the vast array of other channels available to us. To change channels, he explains, we first need to accumulate energy, by practicing rituals that are deliberate, precise and repetitious. Do this long enough and eventually our stored energy precipitates a shift to a channel where self-importance and self pity become impossible. Once this happens we connect with the force that controls the entire universe, a force don Juan called "intent," and everything can be bent to our will and even more channels can be opened, assuming we remember to keep practicing the rituals that save our energy.
This one realization alone was enough to inspire me to dedicate my autobiography "To Carlos, with gratitude."
Maxwell Austin van Lack, Author of The Vortex: A True Story of Passion and Karma
The master gives his all. .......2007-01-10
You have to read all the previous works to see how simple it is, otherwise you miss the profundity. He could have been a trickster at one point, but that ws long ago. Don't even dream of starting Castaneda with these later books. Take the time to ground yourself with his earlier works.
Carlos Castaneda's "Active Side of Infinity".......2007-01-04
This is a wonderful book giving many details not chronicled in his previous books of his encounters with his guide don Juan Matus. He wrote this book just before his death, and it gives the reader a great inside glimpse or more into his mind-set at that point in his enlightenment process. Much of what he details in this book happened much earlier in his process. I truly enjoyed reading this and all of the other books I have previously read that he wrote earlier, but this book is one that I intend to keep for further reference and rereading.
enthralling.......2006-06-04
After reading all Castaneda's other works, this one seems to tie them all together in a most favorable way. Read start to finish, randomly, backwards or just a bit at a time. All of Don Juan Matus' remarks are truly magical.
The Active Side of Infinity.......2006-03-16
I have read and enjoyed all of the books written by Carlos Castaneda, with the exception of The Second Ring of Power. However, for the first time, in his book The Active Side of Infinity, I felt that Carlos Castaneda was revealing more about himself, than he had ever done in any of his previous works. I found this book to be an excellent synopsis of his life both before his apprenticeship and during his apprenticeship with don Juan. If you, like me, have been bedazzled by all of the information contained in his earlier works, you will find this a marvellous book for consolidating much of the information that you have read but not truly internalised.
Book Description
In 1960, five young men arrived at the imposing gates of Parkminster, the largest center of the most rigorous and ascetic monastic order in the Western world: the Carthusians. This is the story of their five-year journey into a society virtually unchanged in its behavior and lifestyle since its founding in 1084.
An Infinity of Little Hours is a uniquely intimate portrait of the customs and practices of a monastic order almost entirely unknown until now. After five years each man must face a choice: if they stay to make "solemn profession" they will never leave. But if they leave, they will be turning their backs on a journey to find God in solitude--their life's ambition. A remarkable investigative work, the book combines first-hand testimony with unique source material to describe the Carthusian life. And in the final chapter, describing a reunion forty years after the events described elsewhere in the book, Nancy Klein Maguire reveals which of the five made it to the top of the mountain.

Many are called but few are chosen.......2007-09-03
I have to admit to an historic link with Parkminster (the location of this book) and the monastery in Switzerland through professional work not religious in the 1980s. My dealings with one of the monks named (Dom Bruno Sullivan) entailed a one day visit to Parkminster and the memory still lives with me (the bus trip into the middle of forest land from Worthing after a train ride from Victoria station and the long walk from the bus stop to the Carthusian abbey gate to ring the bell to gain entry are exactly as depicted in the book). The photo contained of the two floor library with all its old priceless editions of religious books was one of my fondest memories during my visit.
But this book is much more than just story telling - it is a well recorded journey of how five novices in the early 1960s took the step close together in time to enter Parkminster to see if they had sufficient spiritual vocation to be able to remain for life in a virtually silent contemplative religious order where monks, brothers and novices spend most of their time in their private cells praying or involved in solo activity, mainly leaving their cells to only participate in set daily services with the rest of the Order. The repetitive daily routines little changed from the Middle Ages with no major routine changes except in diet and religious prayer when holy feast days arise, would be a test of anyone's spirit. The fact few made it through the five years to becoming a monk did not leave any of those failing as bitter - rather they saw it subsequently when the author contacted them recently as the high point of their lives.
What makes this book so exceptional is that in covering a very private and personal approach to religious life where the inward thoughts and emotions are everything, is all accurately captured by the writer, herself a lady married to one of the ex-novices. Over the nearly seven years writing the book she was surprised at the level of openess and honesty she encountered both with the ex-novices and the monks currently still at Parkminster. She also is able to balance the personal stories with the history of the Order, the Order's approach and administration in their chosen life and the wider context within the Catholic church.
Overall she writes lucidly and keeps your interest - never once in the 240 odd pages did I find the lack of action or her coverage of the simple repetitiveness of the lifestyle boring.
As with the almost contemporary film release "Into great silence" on the French monastery at Grande Chartreuse, one wonders why the Order has decided to open itself up in this way at this point in time but we are certainly the richer for the knowledge gained as a consequence.
Much food for thought.......2007-08-21
Reading this book is like finding an oasis in our hectic world. It moves the reader to look at the pace of his/her life and distinguish the "worthwhile" from the "not as important as I thought" - a fascinating study.
Interesting look into the lives of 5 young men.......2007-08-21
I found this interesting as I learned more about the monk's structured society and the types of men they enticed to join them. The five young men that rang the bell that day had a path that most wonder about. This book helped explain how a person's seeking to get closer to God can influence others as well. Nancy has done a lot of research and it paid off.
A life of simple, quiet contempation.......2007-08-10
I concure with many of the reviews posted and would also recommend both the movie and the soundtrack as means of having a little quiet conememplation added to our already hectic modern lives.
By the way, Amazon has the BEST price I've found on the hardcover edition, it's even CHEAPER than most people want for the paperback edition.
A Beautiful Sojourn.......2007-07-22
A nearly perfect book, AN INFINITY OF LITTLE HOURS is one of the best non-fiction works I've read on any subject in some time. Meticulously researched and beautifully written, the book serves as a guide to the austere, eremitic Carthusian life as it was experienced prior to Vatican II. As the author, Nancy Klein Maguire, notes, there's not a lot available for the layperson to read about this order of monks cut off from the world, and whose way of life has changed little since the 11th century. We are truly fortunate, then, to have Maguire as our host for this journey.
Maguire follows the lives of five young men who entered the Parkminster Charterhouse in England in the years 1960 to 1961: three men from the U.S. (Chicago, Philadelphia, and Brooklyn), one from Germany, and another from Ireland. That they do not all stay in the life quickly becomes clear, but wondering who stays and who leaves is part of the charm. (Warning: the photos are spoilers for the ending.) What's really wonderful is how Maguire gives the reader a chance to experience vicariously these men's lives from the point they literally approach the door of the Charterhouse and enter into its life to the time they leave or become professed. We are seduced by the life, but also acutely feel its physical discomforts. We grow with the men as the initial romance wears off, and the political reality of divisions between the monks becomes apparent. In the end, we are enchanted by the monks who persevere in the life, but also embrace the men who leave, fully sharing their relief. Maguire is a gifted writer; her prose is like freshly made butter, smooth and delicious. I think I could read anything she chose to write next, and plan to.
What profoundly struck me in reading Maguire's book was how these men, in entering the Carthusian life presumably to stay to the end of their lives, were essentially preparing for their deaths. At first I found the notion bewildering, even suffocating. I mean, our culture celebrates youth and fears death, doesn't it. Reading this book really made me think a lot about death. Could I forgo all that the world offers, close myself off forever within stone walls, and search for God while awaiting death under the same routine for decades? Happily married and middle aged (the Carthusians don't accept candidates older than 45), I know that the question is moot--but would I have been able to accept the life at 21? And am I ready now to look straight in death's face? How deep is my faith?
If you have any interest at all in the Carthusians or in monasticism, you will want to read this book. It makes a nice companion to the recently released, splendid documentary on the Grande Chartreuse, INTO GREAT SILENCE.

For the Students!.......2002-07-23
Courses in harmonic analysis have a central place in the course offerings of every math department, be it pure or applied;-- and the subject is as important as ever! Yet it has not always been easy for an instructor to find a book that is right for the students. Some books might be too skimpy on proofs, or not deep enough.-- Or the applications may somehow be artificial, or contrived. Afterall, we teach the material to engineers!-- It is a relief to find, in Pinsky's lovely new book, a balanced approach to the subject. The motivation and the history receive a beautiful presentation, as do the technical points and proofs. And the historical comments- sprinkled throughout the book- bring the subject to life. At the same time, the book is forward looking, and it has been tested in courses. Great exercises! The structure of the exposition is friendly, and gently leads the reader toward the exciting new wavelet material in the last hundred or so pages of the book. The student thereby gets a sense of how the central questions in wavelet theory have their root in the more classical ideas of harmonic analysis.
Book Description
A bottom-up approach that enables readers to master and apply the latest techniques in state estimation
This book offers the best mathematical approaches to estimating the state of a general system. The author presents state estimation theory clearly and rigorously, providing the right amount of advanced material, recent research results, and references to enable the reader to apply state estimation techniques confidently across a variety of fields in science and engineering.
While there are other textbooks that treat state estimation, this one offers special features and a unique perspective and pedagogical approach that speed learning:
* Straightforward, bottom-up approach begins with basic concepts and then builds step by step to more advanced topics for a clear understanding of state estimation
* Simple examples and problems that require only paper and pen to solve lead to an intuitive understanding of how theory works in practice
* MATLAB(r)-based source code that corresponds to examples in the book, available on the author's Web site, enables readers to recreate results and experiment with other simulation setups and parameters
Armed with a solid foundation in the basics, readers are presented with a careful treatment of advanced topics, including unscented filtering, high order nonlinear filtering, particle filtering, constrained state estimation, reduced order filtering, robust Kalman filtering, and mixed Kalman/H? filtering.
Problems at the end of each chapter include both written exercises and computer exercises. Written exercises focus on improving the reader's understanding of theory and key concepts, whereas computer exercises help readers apply theory to problems similar to ones they are likely to encounter in industry. A solutions manual is available for instructors.
With its expert blend of theory and practice, coupled with its presentation of recent research results, Optimal State Estimation is strongly recommended for undergraduate and graduate-level courses in optimal control and state estimation theory. It also serves as a reference for engineers and science professionals across a wide array of industries.
A solutions manual is available upon request from the Wiley editorial board.

Of the 4, Dan Simon's Optimal State Estimation is by far the most useful for a GNC Engineer like me. He strikes a good balance between theory and practice and his examples are really useful. I find his treatment of EKF excellent.
Excellent treatment of nonlinear filtering, especially filters related to unscented transforms.......2007-07-25
I'm using this book to apply the unscented Kalman filter to multiple sensor target tracking. His exposition on the unscented transforms is very clear.
I read some articles of Prof. Dan Simon in Embedded.com.......2006-12-10
I found his articles are intuitive and useful for my research.
If you are engineer who need to apply observer and estimation into your work. This book is good book.
Book Description
Over 120 delightful pen-and-ink illustrations by the author add another dimension of good-natured charm to these wide-ranging explorations. A mind-expanding volume for the layman and the science-minded.

Don't Think Too Hard.......2007-09-22
This book takes very complex theories and theorems and puts them into simple, everyday words that most of us "regular" people can understand. By finally understanding them, you yourself will start to boggle your own mind thinking about other theories and maybe, if fortunate enough, will even form your own.
What a book!.......2007-09-04
I somehow came across this book when I was about 12, started reading it, and couldn't put it down. Now at the age of 52, I happened upon it once again, started reading it, and once again couldn't put it down. The delightful style of writing of Mr. Gamov, along with his tremendous knowledge, make this book a real gem. Highly recommended for children or adults with an inquisitive mind.

"In plain words our result means: the most probable distance of our drunkard from the lamp post after a certain large number of irregular turns is equal to the average length of each straight track that he walks, times the square root of their number." G. Gamow
Exploration of scientific puzzles:
One book, which I read in 1960 (The Revised edition) when I graduated in Engineering was, "One, Two, Three... Infinity," a wonderful book by George Gamow who explored science and its speculations. George Gamow, a nuclear physicist wrote an entertaining book, describing the wonders of nature and, how we understand facts and perceive issues about the universe. That book was selected as one of the top 1000 books ever written, translated in Egypt to inform the younger generation of the New republic. The fascinating chapters of the readable book on contemporary science, takes you from playing with numbers to the microcosmos on: number theory, relativity, fourth dimension, entropy, genes, atomic structure, the riddle of life and the days of creation.
Storytelling by a Renowned Physicist:
In a storytelling style with which the author and great mathematics educator, George Gamow, approaches his subject and grabs the interest of the reader goes far beyond math, science, physics, and mere numbers placed in esoteric formulae. Continuing on through more exploration of mathematical randomness, and statistical approximation of probabilities, simple game theory and related problems. Gamow leads the lay reader from mathematical complexity into a treatment of aspects of organic chemistry to genetic theory, and out to a cosmological mindwarp territory, taking you from the roots of the ancient Alexandrian world through early and later geometrical analysis and extrapolations from the phenomenon of parallax, to the spherical shape of earth by an early Alexandrian mathemetician, Eratosthenes. Gamow diligently coaches the novice through passing items such as supernova explosion, galactic clusters, a collection of diverse examples of stars and stages of their development, expanding of the Universe as the expanding of a balloon's surface, with points on the surface all retreating from all others at the same rate (fig 127). The volume contains over 120 delightful pen illustrations by the inspiring author, adding another dimension of good-natured charm to these wide-ranging explorations, a mind-expanding volume for the layman and the science-minded.
Book Recent Review:
"Gamow did indeed 'strive' ... in One Two Three...Infinity - to 'emphasize' the importance of science and technology. ...In his original Preface, written in 1947 at the time the book was first published, ...he did not 'attempt to tell the whole story" of modern science; he also shows his ability to understand and be modest when he writes..." Academon
"It seems that almost all the reviewers had the same experience: we read this book at an early age, and it was so fascinating, so inspiring, and so magical that it directed us into math and science for the rest of our lives." Stan Veroony

Can you count INFINITY?.......2007-07-14
Can infinity be counted? Is there more than one type of infinity? Answer: Yes to both questions. Learn how counting things that (seemingly) cannot be counted is done - and, while you're at it, learn about the fourth dimension.
A classic that has been recommended reading for over 50 years!
99% is unrelated to infinity.......2007-06-30
The book, contrary to its title, talks little about infinity. About 1% of the book is dedicated to the subject. The rest of the book is an 8th grader's introduction to science. The concepts are very basic and while the ideas are explained well this book is not intended for any kind of introductory study except for those individuals who have a very limited concept of science in general.
Book Description
This monograph contains 10 lectures presented by Dr. Daubechies as the principal speaker at the 1990 CBMS-NSF Conference on Wavelets and Applications. Wavelets are a mathematical development that many experts think may revolutionize the world of information storage and retrieval. They are a fairly simple mathematical tool now being applied to the compression of data, such as fingerprints, weather satellite photographs, and medical x-rays - that were previously thought to be impossible to condense without losing crucial details. The opening chapter provides an overview of the main problems presented in the book. Following chapters discuss the theoretical and practical aspects of wavelet theory, including wavelet transforms, orthonormal bases of wavelets, and characterization of functional spaces by means of wavelets. The last chapter presents several topics under active research, as multidimensional wavelets, wavelet packet bases, and a construction of wavelets tailored to decompose functions defined in a finite interval.

Well... It was written by Ingrid!!.......2007-05-14
What can I say, Wavelets explained by Ingrid Daubechies! You can't go wrong.
Over rated.......2002-12-24
There are so many well written books on Wavelts out nowadays. Don't waste your money on this one. It's famous because it was first (or one of the first). On the positive side, it does present a strong mathematical foundation. I recommend you buy a readable book (just do a search on Amazon.com and you'll find half a dozen great books on Wavelets), then when you approach the "expert" level, use this one a s a reference (if at all).
Great for everyone!.......2002-07-11
This book has become a classic,-- and a hit;-- for more than ten reasons. It is multilayered, and yet presents a unity of ideas: The material, and the writing is engaging for the beginner, and for the research mathematician alike. When I used it in my teaching, it was equally popular with the math students, and those from engineering. I don't know if I can say this about any other book I have taught from. The students could follow all the carefully presented proofs, and the engineer could generate algorithms from the applied chapters.
Not for the faint of heart!.......2002-05-24
This book is a treasure of details if you know what you are doing. As another reviewer noted, it is not for the beginner. But if you have had some experience with the subject this is a must have for your library shelf.
Theoretical Wonder....but you won't learn wavelets from it!.......2000-10-10
This is the document that started it all. It is by far a great mathematical and theoritical piece of work. HOWEVER, if you are just starting off and want to learn about wavelets and do not have an advanced math or engineering degree (and I do mean ADVANCED), do not pick up this book. At least not at the beginning. There are much better books written for explaining wavelets and to better present the material. Ten Lectures is essentially one big proof. Try Mallat/Kovacevic or Strang...once you've got a solid understanding, come back to Daubechies and marvel at her work.

Good for Fourier analysis and much more.......2005-12-04
This Schaum's outline is unique in that you not only get a thorough coverage of Fourier analysis, but of other orthogonal functions such as Bessel, Legendre, Hermite, and Laguerre. The first chapter would be interesting to students of partial differential equations because of its excellent treatment of boundary value problems and of the different types of partial differential equations. It makes an interesting first taste of PDE solution methods. Chapter two is a traditional treatment of Fourier series and its applications. As in the first chapter, it is the applications that make the chapter unique as the Fourier series is used to solve problems in heat flow, Laplace's equations, and vibrating systems. Chapter three has a good discussion of why you would actually care if a function is orthogonal. Chapter four discusses special functions and how they are evaluated. Chapters five and six are all about applications of the Fourier integral and of the Bessel function respectively. Chapter seven uses the Legendre functions to solve problems such as finding the potential interior and exterior to a sphere given a specific charge distribution. Chapter eight finishes the guide with a discussion of Hermite and Laguerre polynomials, more from a properties standpoint than from an applications standpoint. The reader of this guide should already be knowledgeable of Calculus and differential equations, and should probably have some kind of background in physics or engineering to get the most from the book. It would be a good supplement for the student of partial differential equations or signal processing as well as the student of Fourier analysis. I think what really sets this book apart is its ability to act as a stand-alone guide to the student with the required prerequisites and to actually to inspire you to study applied mathematics more. As for my own story, I picked up a previous edition of this book 17 years ago for a coworker that thought it might be helpful in a class he was taking. He decided he didn't want it and so I began thumbing through it. I found the applications sections to be so interesting and inspiring that I wound up going back to graduate school and eventually picked up three master's degrees! If you like this Schaum's outline, you might also want to pick up "Schaum's Outline of Advanced Mathematics for Engineers and Scientists" by the same author. It is also full of mathematics inspired by real world problems in need of solution.
Step-by-step explanations.......2002-08-28
This text is a good supplement to understanding the use of Fourier analysis and how it is used in real-world applications. The explanations are to the point and the solved problems are all fairly easy to follow.
At the end of the chapter, there are exercises to test your knowledge, and most of the answers are in the back of the book. Modeling the exercises on the problems, you can usually work out what you should do for the exercise.
This is a good study guide.
Good study aid!.......2000-03-28
Very helpful to me in my medical imaging and signal processing assignments! A good buy for any student of engineering or science, particuarly useful to the study of signal analysis.

Hard Disk Drive: Mechatronics and Control (Automation and Control Engineering)
ASIN: 1846283043 |
Book Description
The second edition of this monograph provides a systematic treatment of the design of modern hard disk drive servo systems updated with the latest research results to reflect recent improvements in spindle speed and bit density and other changes in this fast-moving field. In particular, it focuses on the applications of some newly developed results in control theory, i.e., robust and perfect tracking control and composite non-linear feedback control which are suitable for track following and seeking respectively. Emphasis is placed on hard disk drive servo systems with single- or dual-stage actuation using a voice-coil-motor actuator enhanced in the latter case by the addition of a micro-actuator providing faster responses and therefore higher bandwidth in track following. Other issues such as modeling and compensation of nonlinearities and friction in microdrives, disturbance rejection and resonance compensation are also addressed.
The techniques and applications involved include:
- time- and frequency domain methods for system identification;
- physical effect approaches for parameter identification;
- linear systems tools;
- linear control techniques (PID,
H
2,
H-infinity, and other robust control methods);
- classical nonlinear control techniques (time-optimal, proximate time-optimal, and mode switching control);
- composite nonlinear feedback (CNF) control;
- complete single- and dual-stage hard disk drive servo systems;
- time- and frequency domain properties of hard disk drive servo systems;
- design of piezoelectric actuator systems;
- modeling and compensation of nonlinearities and friction in microdrives.
Hard Disk Drive Servo Systems will be of great value to practicing engineers in the hard disk and CD-ROM drive industries and to researchers in areas related to servo systems. The Linear Systems and CNF MATLAB
® toolkits used to develop many of the results in this book can be downloaded from Professor Chen’s website.
