ASIN: 1402074220 |
Book Description
Computational chemistry has become extremely important in the last decade, being widely used in academic and industrial research. Yet there have been few books designed to teach the subject to nonspecialists.
Computational Chemistry: Introduction to the Theory and Applications of Molecular and Quantum Mechanics is an invaluable tool for teaching and researchers alike. The book provides an overview of the field, explains the basic underlying theory at a meaningful level that is not beyond beginners, and it gives numerous comparisons of different methods with one another and with experiment.
The following concepts are illustrated and their possibilities and limitations are given:
- potential energy surfaces;
- simple and extended Hückel methods;
- ab initio, AM1 and related semiempirical methods;
- density functional theory (DFT).

Very good first intro to computational chemistry.......2004-08-28
Rough reading.......2004-05-12
Lewars introduces the easy parts in a clear enough way. Potential energy surfaces make sense. Molecular mechanics has a good, intuitive feel - it's the springs-and-balls model, elaborated to include plane and dihedral angles, representing force fields derived from other sources.
After that (i.e., after p. 80), it's quantum mechanics for a few hundred pages. The premise is that the layout of electrons across a molecule determines its chemistry, and that the wave function tells where the electrons will be. Since the wave equations can't be solved exactly for anything with two or more electrons (!), it's actually approximations to quantum. That leads to two levels of opacity: quantum itself, and all the facts that were scraped off in the approximation process. At this point, the chice is binary: become fluent in quantum, or move on. There are a few nuggets to be had for the non-fluent, including some of the techniques for solving these horrendous integrals. Mostly, though, I moved on.
After the "ab initio" quantum mechanical methods, Lewars presents the semi-empirical models. These deal with simplified models of wave functions. Unlike ab initio methods, which stand on almost purely theoretical models, semi-empirical methods are informed by experimental data. They are based on the electron wave functions, as are the ab initio methods, but use approximations calibrated by experimental results. The book's final section presents density functional theory (DFT), another technique for estimating where the electrons will be.
This book demands a lot of the reader, more than I came in with or had time to develop. I was able to use it to get a working vocabulary of the major kinds of computations, the general categories of approach to modeling, and a rough idea of the techniques and complexities involved. I need a little more information than that, but not the immediate leap into the deep end presented here.
I look forward to a review by someone more knowledgeable. For now, my only real criticism of this book is lack of glossary. Initialisms and acronyms abound. It would have made the going a lot easier if the book had one place where I could refresh my memory on the dozens or hundreds of abbreviations.

Wildlife of Gondwana: Dinosaurs and Other Vertebrates from the Ancient Supercontinent (Life of the Past)

Amazon.com
From the late Paleozoic era to the early Mesozoic era, 350 million to 140 million years before the present, the latter-day continents and subcontinents of Antarctica, India, Australia, Africa, and South America formed a single landmass, a southerly "supercontinent" that contemporary scientists call Gondwana. The physicist Alfred Wegener posited the existence of Gondwana as early as 1912, but only in the 1960s was his theory of continental drift widely accepted. Since that time, considerable evidence has been gathered about Gondwana's ancient flora and fauna, much of it from Australia, which the authors of this handsomely illustrated volume deem a kind of "Noah's ark" of species found almost nowhere else.Some of those animal types, such as the allosaurid dinosaurs and the labyrinthodont amphibians, may have endured on Gondwana long after they went extinct on its northern-hemisphere counterpart; others, such as the placental mammals and certapsian dinosaurs, may have developed on Gondwana. First published in 1992, this book offers a useful introduction to plate tectonics and other tenets of modern geology, as well as a fine catalog of long-extinct creatures such as the sauropod, pterosaur, and iguanodont. The revised edition recounts recent discoveries from southern Africa, India, and Patagonia that augment the fossil record and correct earlier classification schemes. --Gregory McNamee
Book Description
Before the six major continents were separated by vast seas, there existed the landmass of Gondwana (now Australia, South America, Antarctica, India, Africa, and New Zealand). This book presents the history of the vertebrate faunas of Gondwana, beginning with the origin of life, even before Gondwana coalesced, and moves through time as the continent shifted, along with its vertebrate life. Lavishly illustrated with hundreds of color photographs, drawings, and paintings, Wildlife of Gondwana is a major reference to life of the past. Originally published in Australia in 1993, this corrected and augmented edition contains new material on fossil discoveries in India.Customer Reviews:
Gondwana? No. Austrlaia? Yes........2004-11-07
not what it seems.......2003-10-02
The chief value of this volume lies in its highly inclusive selection of spectacularly fine and detailed photos of Australian vertebrate fossils, including one of the famous opalized plesiosaurs. Alas, though, there are only a handful of whole-body reconstructions, though those few are very good.
Another problem, endemic to coffee-table books of this kind, is inconsistency of labeling, terminology, and interpretation. The authors can't decide, for example, whether sloths, armadillos and so on are to be called Edentates and placed among the placentals, or should be taken out of the placentals and called Paratheria. Similar inconsistency plagues the coloring of some geological maps, and even the definition of "teleost."
very nice book on Australasian fossils.......2001-03-03
Accompanying the photographs are short articles detailing various aspects of the region's history, such as extinction of Australia's Quarternary megafauna, the floodplain faunas of the Great Southern Rift Valley of the Early Cretaceous, the role the increasing aridity of post-Miocene Australia played in evolution, and the fauna of the Gogo Reef. Longer articles deal with the basic geologic and paleontological history of Gondwana, the history of research there, and the role of Gondwana in the global context of worldwide evolution of animals. Numerous photographs of wildlife today accompany discussions of the unique biogeography of Australia and the role isolation has played in the development of the organisms there.
A beautiful coffee-table book, I hold from giving five stars for two reasons. One, the price is fairly high; though a really nice book to own, it may be out of the price range for many, or at least more than they really want to pay. Two, though the numerous photographs of fossils in the book are really high quality, I think the book could have benefitted from more artists' illustrations of the animals and their environment in life. Though a few nice ones are included, several more could have really added to the value and popular appeal of this book. Many of the extinct fauna of Gondwana are bizarre and fascinating, particularly some of the extinct marsupial megafauna, and it would have been nice to see more illustrations of how they looked in life. All in all though a really well done book.

Book Description
This book provides a unique examination of the software development process, arguing that discipline, still dominated by methods conceived in the framework of older technologies, must undergo a fundamental reexamination of its guiding principles in order for significant progress to take place. To gain fresh insights into how we ought to direct future research, the author begins with a search for first principles. The book begins with an exploration of the scientific foundations of computer technology, then examines design from the perspective of practitioners. The book also offers a critique of the methods employed in software development and an evaluation of an alternate paradigm that has been used successfully for 14 years. The concepts reviewed here comprise a set of core readings for understanding the research and development challenges that will confront computer technology in the 21st century and will be of great interest to computer science researchers and educators, graduate students, and software engineers.Customer Reviews:
