Fantastic collection of stories - the perfect gift.......2007-08-10

This hardbound collection of Virginia Lee Burton stories is one of my essential gift ideas for little ones. Not only are the stories filled with memorable characters (Mike Mulligan and Mary Anne, the Little House, Maybelle the trolley to name a few), but the stories have meaning - the the ideas of hard work, trustworthiness, self-reliance - topics that children don't necessarily understand but need to learn - pervade the stories. Additionally, the illustrations are vivid and captivating for little ones. This collection is a great addition to any child's personal library and makes the perfect gift, especially since it's under $14.00.

What a great compilation of wonderful children's stories. My family loves this book and we love Virginia Lee Burton!

My kid won't put it down........2007-07-13

He absolutely loves this book. Not just the Mike Mulligan story, all of it. Be warned, it is a pretty long book, and he makes us read through it all the way, every time. He is three and a half.

Wonderful book.......2007-07-09

What a wonderful classic book - a keeper - my almost-4-yr-old asks for the stories again and again. I'm torn as to whether it's better to have the compilation or go ahead and purchase the individual books - these are so lovely it's worth spending the money. I didn't read the description carefully enough and was disappointed that "Choo-choo" was not included here, but no big deal, it was nice to have a couple of unfamiliar stories along with the familiar ones.

A Must Read.......2003-02-20

As an amateur aquarium enthusiast, I've had trouble obtaining accurate and reliable information about the design and functioning of aquatic systems. This book takes a serious top-down approach so the reader can drill-down as far as he wants into theory and mathematics to satisfy his curiosity. It is well organized and concisely written. The chapters on ultraviolet sterilizes are particularly well-done. I can now hold my own with retailers and manufacturers' representatives who push buyers towards high cost solutions that are inefficient or don't work. Now if Mr. Escobar would take on natural aquatic systems, I might learn the relationship between sunlight and artificial ultraviolet lighting as it relates to the control of algae!

A step forward but only 1 Step.......2001-07-18

More facts and science and less anecdotal data and conventional wisdom is long overdue in the aquaria hobbies. This book is a step in that direction. This is not a book with lots of colorful pictures that merely repeats what has been repeated in so many other books on aquaria, with or without any factual basis. This book presents models of several pieces of equipment used in aquaria systems. The models use quantitative elements (i.e., expressable as numbers), then present the math to show how the models work.

For example, if a water pump can pump so many gallons per hour, how long will it take for the pump to process all of the water in the tank? (It's not as simple as you might first think.) This book presents a model for that. Models are presented for sizing Ultraviolet sterilizers, skim filters, and determining processing rates for water processing devices generally.

But it is not all science; there is dogma here too. An unsupported claim is that ultraviolet sterilizers are one of the most important pieces of equipment for an aquaria. This is controversial at best and just plain false at worst. But in any event, there is no scientific support for the claim in the book.

The models are somewhat lacking also. The processing model for sizing ultraviolet sterilizers and determining proper flow rates does not take into account the replication rate of organisms. In fact, this matter is swept away with a wave of the hand, basically saying if you want to pick a different processing rate, go ahead. But no accurate model of sterilization can ignore the math involved with the rate of bacteria or protozoa replicating.

The models also assume, quite impractically for real application of the models, that whenever a pump, filter or ultraviolet sterilizers returns water to a tank, the water is instantly and thoroughly mixed with the other water in the tank -- instant homogeneity. This assumption is useful in simplifying the model but it hardly applies to any real world situation. So the formulas for determing the number of times a given device will turnover all the water in an aquarium has little practical application. But even if that were not a problem, the correct number of turnovers is assumed more or less--unless you know a lot more about bacteria decomposition in various filters than most people do.

This book does a reasonable job of explain how the models are built. But the books focuses on certain equipment (the kind author's company sells?) and ignores others without presenting any scientific support for those choices. The book describes water pumps but only those having two moving parts; it ignores water pumps that have only one moving part, such as Eheim has used for years.

When presenting the formula for selecting a heater, the formula doesn't facdtor in the heat from water pumps (almost all water pumps, powerheads, filter [umps use the aquarium water to dissipate motor heat), lights, etc. So practical application of the formula is limited.

The book doesn't note the characteristic problem with fluidized bed/sand filters. All types of filters have good and bad points. The famous bad point of fluidized bed filters is that once the flow throw the sand becomes uneven at all, the unevenness exacerbates itself until you clean or replace the sand. And it's not hard for the sand to develop some uneveness.

So this is a good book as far as it goes. Rather than just saying, for example, this kind of filter works, it provides a mathematical model of (some of) how it works. That's a step in the right direction towards putting more science and less marketing hype and merely anecdotal data in the hobby. Developing the formulas is the right idea, but the formulas are not yet complete --and they focus on some equipment ignoring other, in some cases mor common, equipment. So it is only one step in the right direction; it doesn't make the whole trip.

With that in mind it's worth reading, although maybe best borrowed once from a library.

wonderful but confusing!!!.......2001-06-28

hope you know your algebra kiddies, this book has plenty of it, but many helpful insights on how to stop wasting your money on things that do not work, and why, we dug it!! the equasions are kinds confusing though nikki

Technical... but full ok knowledge.......2000-09-05

Although a bit technical at times, Escobal's book is designed to literally teach aquarists the often mysterious ways our aquatic devices really work. As a dedicated aquarist, I have tinkered with all my aquariums for a long time but, it was not until I got this book, that I truly began to understand the chemistry or physics behind the diverse array of filters, protein skimmers, reactors and so forth, that are part of this hobby. The book is written like a textbook and it includes exercises, examples, charts and graphics. As a result, the reader can absorb the contents as his/her own pace and safely tinker with his/her own devices at home. Although at times too technical, the book is a true jewel to be cherished by all who love aquatic life and strive to keep it alive and well in their aquariums.

Great but always missing the final simplification..........1999-06-07

25 years ago I made a living of Dr. Escobal's book on celestial mechanics. I was in awe of him then and now.

This book is unique in aquaium hobby (all fish?) books in as much as it actually derrives things from first principles. Which is fascinating for a fellow physicist/EE.

My only complaint is that a little intuition would always motivate the math and usually give the same results. I.e if the range/depth dissapation of a UV light in H20 is 2", it's too not surprizing that with a 1" light tube the optimal diameter is around 3", etc. Using that result it's pretty simple to get the dose. I came at it the other way and loaded all the math into Mathematica and played around with different limits/optimizations for a while until the light turned on. So sometimes the results seem more analytical than they might be, but they are important results: use a flow meter!

Mixed Feelings.......2006-03-22

This book contains many interesting information, guides and principles, but also has too many general talk.

Many concepts and thoughts presented refer to real-life situations and show that authors have comprehensive experience, but at the same time are not developed enough - they very easily end in good-sounding general talk.

Ideas and concepts in this book can trigger some iniciatives in practicioner's office, but everything must be re-worked to have any usefulness in real life.

Learn How to Manage Maintenance from a Real Pro.......2001-12-18

Maintenance is one of the, if not the, most difficult functions to manage and control in industry. Left alone, maintenance tends toward chaos: fighting fires, too busy for PM, repeat failures, with senior management often unappreciative and non-supportive. Nevertheless, without good maintenance, industry can't run. How does one move from chaos to Control?

Mr. Nyman has written the definitive how-to on this subject, and no Plant Engineer or Maintenance Manager should be without this book in his library. If you will not just read, but absorb, the contents of this book for Mr. Nyman's insights, and follow his prescription for planning and scheduling, you will make the move to Control, and make your life, and your job, much easier.

This book gives detailed explanations of the Maintenance Planning function, including both Planner and Supervisor roles, with specifics on the process of how to scope out a job, determine material requirements, coordinate multiple craft groups, estimate time requirements, and then to effectively schedule planned jobs.

The book also includes appropriate metrics for measuring maintenance performance, Planner as well as Supervisor - a topic that is especially important since maintenance is mostly about cost avoidance, which itself is almost impossible to measure.

Here's a mesmerizing account of the evolution of machines and thoughts about machines, woven into a story about the evolution of intelligence. Darwin Among the Machines is not so much about how today's intelligence came to be, but about how it may further develop as humanity and computer grow closer together. George Dyson tells the story largely through stories--both historical and legendary--from the lives of scientists and philosophers who paved the way for today's cybernetics revolution, starting with the 17th-century insights of Thomas Hobbes. This book challenges the assumption that nature and machine are opposing forces. Dyson believes them to be allies.

Book Description

George Dyson grew up at the Institute for Advanced Study, where such scientists as his father, Freeman Dyson, and John von Neumann laid the foundations for the Information Age. From this vantage point, and with an unprecedented cast of characters, Dyson traces the course of the information revolution, illuminating the lives, work and ideas of visionaries who foresaw the development of artificial intelligence, artificial life, and the global mind.

Customer Reviews:

Maybe not scientific, but that's not the point anyway..........2006-07-09

Several have criticized Dyson's philosophical and historical treatise "Darwin Among the Machines" for not articulating exactly how a global intelligence might emerge from today's synthetic biological and computational networks. But as Dyson says in the preface, the past is where we find answers, and the future merely a fog of questions "to which the answers are up to us." In the next 200 pages, Dyson explores the history of an idea: that man will someday create a form of artificial life, with intelligence that may match or exceed our own.

It may astound some readers to know that these ideas date much farther back than Alan Turing's "Turing Test," or Vannevar Bush's influential essay "As We May Think." Consider the following quote from Thomas Hobbes (1651): "Nature is by the Art of man, as in many other things, so in this also imitated, that it can make an Artificial Animal." Or consider this excerpt from Samuel Butler's 1859 essay, which serves as Dyson's main theoretical foundation: "As the vegetable kingdom was slowly developed from the mineral, and as in like manner the animal supervened upon the vegetable, so now in these last few ages an entirely new kindgom has sprung up ... It appears to us that we are ourselves creating our own successors."

Careful to acknowledge his predecessors, Dyson profiles the lives of some of the most prescient Enlightenment- and modern-era thinkers in captivating detail. In so doing, he traces the evolution of the "Artificial Animal" from its earliest incorporeal appearances - as merely an idea - to its current computational incarnation in neural networks. But Dyson doesn't stop there.

In fact, he goes on to argue that the global telecommunications network (primarily the internet) may provide the appropriate architecture for a kind of global, distributed intelligence to evolve. Here Dyson borrows from Leibniz, who noted that the "soul" may be "born when the machine is organized to receive it, as organ-pipes are adjusted to receive the general wind."

To further support this claim, Dyson draws parallels between the development of increasingly efficient machines and the processes of biological evolution. In fact, this is one of the most interesting parts of the book, in part because the language in which Dyson details the principles of evolution might be considered dangerous today, in the midst of the raging Intelligent Design debate. For example, Dyson suggests that evolution itself may embody a kind of intelligence, though we frequently perceive it as merely a shallow process, highly dependent on chance and randomness.

As Dyson points out, this perception gets to a fundamental semantic confusion surrounding "intelligence," a phenomenon well known to AI researchers in which problems once thought to require intelligence are then seen as trivial after an algorithm is designed to solve them. As Dyson points out, intelligence may simply be a word we use to describe behavior that corresponds to our view of how humans behave. Not believing in "'the existence of an intelligence behind the achievements in biological evolution may prove to be one of the most spectacular examples of the kind of misunderstandings which may arise before two alien forms of intelligence become aware of one another.' Likewise, to conclude from the failure of individual machines to act intelligently that machines are not intelligent may represent a spectacular misunderstanding of the nature of intelligence among machines."

Ultimately, whether you agree with Dyson's perspective is besides the point. This is not a scientific book; many of the ideas are purely philosophical, and the logic used to support Dyson's assertions frequently rests on historical anecdote and analogy. These should not be considered weaknesses, however. The real, lasting value of "Darwin Among the Machines" is Dysons's imaginative and graceful writing, his impeccable historical research, and the conceptual ease with which he integrates ideas from ballistics, biology, hydrodynamics, set theory, Cybernetics, and uncountably more esoteric subjects.

Though I won't dispute that many of these exciting ideas are far-fetched, Dyson has found powerful allies for his assertions, from Hobbes and Leibniz to Goedel and Von Neumann. So if you find yourself believing - or simply wanting to believe - in these groundbreaking ideas, then you're in fine company.

EDVAC, Turing, Von Newmann, IAS........2006-04-20

EDVAC architecture by Von Newmann changed the world. Von Newmann chose to adopt the McCulloh-Pitts symbolism for diagramming logical structures of stored program codes. EDVAC had the ability to modify its own instructions similar too the theoretical Turing machine. EDVAC stored both data and instructions in mercury delay-line memory as binary and as in the Turing Universal Machine, long strings of bits represented numbers to be operated on and sequenced and potential dynamic structures of operations to be performed, such as bit shifting, multiplexing, Boolean logic, memory storage, and accumulation.

Von Newmann's next machine was called the IAS. The initial development of the IAS design was distributed to multiple locations. A central processor operating in parallel on multiple bits of a word of data at a time characterized IAS. ISA had a hierarchical memory range with random access to memory on limited media, and a distinction between software functionality and hardware functionality. "Science, as well as technology, will in the near future and in the far future turn from problems of intensity, substance, and energy to problems of structure, organization, information and control." Von Newmann was persuaded that the high-speed computer would change the nature of mathematical research. The IAS machine contained the world's first fully functional random-access memory, RAM. Disk storage was provide through 40 cylinders arranged in a bank of 20 with 1024 bits per cylinder; additionally, 40 Williams tubes and 2,600 vacuum tubes performed digital processing with a 75% up time. IAS included an arithmetic unit, accumulator, two shift registers, an adder, and a digit resolver. Floating point was considered but not implemented. IAS included 20 basic instructions and 44 order codes.

Human calculators provided the pattern of processing modeled in the computer. Human calculators demonstrated coordinated computing, sequencing, and analytical capability. Human calculators worked in parallel managed and coordinated processes deciphered WWI Germany encryption messages. The brainpower and segmented problem solving 10 X 15 power number combinations.

The human calculator model could be simulated in the Von Newman and Turing machine and the connection machine architectures and software. Neural Nets could be model in the Turing machine.

However, evolution algorithms will not be able too produce a thinking machine. Thinking is limited to the humans and divine beings. Behavior can be represented in Finite automata graphs, AFSMs, and mechanized behavior may appear logical but this does not suggest the machine can cross the sphere into human intelligence. The title of the book directly is a criticism against the evolutionary humanist. Turing grammer suggests discrete processes can be interactive described by a language. Computer automata can not evolve beyond discrete functions and the machine will be confined to the range of mathematical theorem proofs. Mathematical reasons does not encapsulate all human reasoning and such an acceptance of this conclusion would be uncreative, limiting, and lacking in vision of the potential for humans to feel love, joy, and acquire greater intelligence.

Von Newmann saw digital computers as mathematical tools, a general class of automata and did not imply they could think. Von Newman became more interested in the machine reproduction. "Every automa that can produce other automa will only be able to produce less complicated ones." Celluar Automa has yet to produce a computer brain that will function. CA algorithms surprisingly can model many patterns found in nature and physics. However, no CA has produced a grammer or graph that can be reproduced by the machine yielding an intelligence reasoning machine. Von Newmann hoped for CA salvation, "there is, however, a minimal level where this degenerative characteristic ceases to be universal. At this point automata which can reproduce themselves, or even construct higher entities are possible." Von Newmann's inspiration was not CA but VLSI. VLSI were being replicated from computer generated patterns by computer operated tool. FAB in the 20th century continued Von Newmann's aspiration and robotic automated factories suggested to a minimum degree the theory had value. Intelligence move counter to entropy and if one observes a machine producing other machines of higher construct characteristics than one would declare intelligence has been proven. In "Flesh and Machine" the Brooks suggests GA do have the ability to create simple behaviors such as locomotion, tactics, and architectural models but fail too create higher-level concepts. Abstracting and creative thought are outside the realm of the machine. Brooks suggests AI breakthrough is limted by a lack of quality software, missing laws of intelligence, slow machines, and entropy caused by a lack of young Einsteins willing to dedicate their brains to solving the AI problem.

Von Newman in his "Theory of Self replicating Automa" believed automa would grow more complicated from one generation to the next; no device would become the brain; high speed switching was millions of times faster than biological neurons but pales in comparison with the combinatorial ability of a billion neurons; and something as complicated as the brain could not be designed but had to be evolved. The idea that perfection could be reached by random arrangement of neurons seems doomed to fail. Von Newmann suggested growing a matrix of artifical neurons. These neurons should have the tendency towards self-organization among large number of interconnected secondary machines. Incomprehensible complex processes among the secondary machines could be observed by humans have the appearance of comprehensible behavior. Brooks simple behavior modeling through AFSM seems too synchronized within the realm of computer theory. Imitation verses enhancement feels like imitation is more discrete, definable, and programmable. Enhancement seems to be the result of complicated imitation and the AI is the failure to adequately define AFSMs too model observable behavior. AI evolution must be confined to the realm of the Turing machine grammar. To expect a machine to suddenly start thinking and its neurons to behavior like biological counterparts is a myth, a fable to consume brilliant minds into the dream that machines can think.

Not entirely satisfying.......2004-12-10

Though well written and informative, in the end DAM was a less than satisying read. Dyson marshals considerable data (and extensive and informative quotes) from the fields of history (of science and technology), the sciences (principally evolution and CS), and philosophy (as it has, historically, reflected on notions of mind and evolution). As an avid reader of history, with a deep interest in all of these subjects, I found the opening chapters of DAM quite interesting. That said, the history in DAM is not particularly deep. But Dyson writes well, and I appreciate his having shed light on several lesser known (and underappreciated) historical figures along the way.

Where DAM ultimately falters, in my view, is in its shallow futurism. I say "shallow" not because I don't think Dyson is highly imaginative. He is. And his predictions (to the extent he articulates them as such) may well be realized one day. However, though Dyson is skilfull in establishing the historical groundwork for the development of computer and communications technology as they exist today, he is far less skilfull in tracing even a speculative chain of developments from the present state of the art to the global/artificial intelligence he envisions as a possible (perhaps inevitable) future development. In fairness, every futurist has hit and will continue to hit this wall until the future comes knocking. But Dyson purports to do so.

In the final analysis, though Dyson does an admirable (and entertaining) job of accounting for the rise of computers, and the increasing complexity of computer networks, his discussion of artificial intelligence has more the ring of a leap of faith. It's a fascinating idea (though hardly original to Dyson), and certainly a possibility, but one whose potential trajectory (from idea to realization) is barely even attempted in DAM. DAM would have profited from a little more hard science, and a little less soft speculation.

Title sizzles, but book was unappetizing........2003-02-15

I bought this book in the hope of reading some intelligent speculations by the author about evolution, machines, and AI, which is what the title suggested I would find. However, it turned out to be a history of the evolution of computers with old speculations from the computer pioneers concerning the evolution of computers injected along the way. To be fair, the author does have an overarching thesis that he tries to weave into the historical narrative whenever some past speculation seems to lend it some support. It is that the World Wide Web - that well known network of millions of computers - may some day, at a certain critical size and running who knows what software (certainly not the author) will become intelligent in some way (also not specified by the author). Come to think of it, I think the author has used the historical angle of the book - the similar speculations of the computer pioneers of the past - as a device to lend credence to his thesis - a kind of proof by consensus. I remain unconvinced, however. His arguments (where there were any; it was hard to tell his arguments from narrative) were very weak and unconvincing. To his credit, the author did a tremendous job of scholarship for the historical side of the book. However, he left the speculative side undeveloped (at the most weakly developed) and, therefore, the book was unappetizing to me.

Good Historical References.......2001-05-01

Another good read on the origins of modern computer science. Some interesting stories of Babbage, Hollerith and Van Neumann. I particularly enjoyed Babbage's human computers.

still loves it a year later..........2006-06-08

This is one of the few books my son still loves after reading for almost a year. I first showed it to my child when he was about 6 months and he liked it right away, now he's 18 months and he likes it even better whereas many other books have fallen to the wayside. The drawings are enjoyable to both the infant and toddler group. When he was young we focused on the animals and their noises, now we are focusing on the tractors and engines, and explaining where food comes from etc. It's a great book.

My two year old son just loves this book! The flaps and all of the bright colors and animals keep him completely entertained. I think it's a great value also. When I ordered the book I didn't realize how big was until it arrived. I would have expected to pay at least $14.99 for a book of this quality and size.
