Book Description

Among the thousands of synthesized polymers, new polymeric substances and materials with new, often unusual, properties arise frequently. This presents a problem in determining the physical properties of polymers and thus makes it difficult to tackle the question of the synthesis of polymers with desired properties. The author has approached this problem in a semi-empirical manner, which like van Krevelen's empirical method is based on the principle of increment and deriving calculations from it, but in Askadskii's approach each equation for the calculation of properties is physically based, and its parameters are connected with characteristics of atoms (Van-der-Waals volume, dispersionic interaction) which compose the reoccurring unit of polymer, as well as with characteristics of energy of intermolecular interaction. Particular attention is paid to the relaxation properties of polymers, which determine the mechanical serviceability of materials.

From the author: The experimental results presented in Part I of this study were used to evaluate the predictive capabilities of two viscoelastic constitutive models. One of the models, developed by Xia and Ellyin, is in a differential form. The other, which is a modified Schapery model by Lai and Bakker, is in an integral form. The results of the comparison indicate that the Xia-Ellyin constitutive model simulated the experimental observations well. This was attributed to the existence of a general rule that delineates the loading and unloading parts of the cyclic response. The modified Schapery model was able to predict the general trends of the deformation behavior; however, it was unable to correctly simulate the unloading behavior. This difference became more pronounced when the applied cyclic stress/strain was high. At high applied loads, the material response became more nonlinear. POLYM. ENG. SCI., 45:103-113, 2005.

From the author: Based on the experimental data presented in Part I, a nonlinear viscoelastic constitutive model, in differential form, is presented here. A distinctive feature of this model is the inclusion of a criterion to delineate loading and unloading in multiaxial stress states, and different moduli for loading and unloading behaviors. In addition, the model contains only five material constants and one modulus function, which can be calibrated in accordance with a well-defined procedure. A comparison with the experimental data shows that the current differential model is capable of predicting the nonlinear viscoelastic behavior of the epoxy polymer qualitatively and quantitatively, including both the loading and unloading behavior. The predictions of an integral form of constitutive model are also included for comparative purposes.

From the author: In-mold shrinkage may occur for product parts that solidify under low holding pressure and are not restricted by ribs or flanges. It not only affects the final product dimensions but in addition may have a large effect on the residual stress distribution. A simple elastic model is used to study the effect of in-mold shrinkage on final product dimensions and residual stress distributions. Friction between polymer surface and mold wall as well as deformation of the mold cavity are taken into account. The model uses local values for temperature, pressure, and crystallization, which belong to the standard output of most simulation codes.

From the author: The thermal conductivity of hemp fiber reinforced polymer composites were studied from the steady state temperature drop across samples exposed to a known heat flux. The transverse and in-plane thermal conductivities for oriented and randomly oriented composites for different volume fractions of fiber were investigated. Experimental results showed that the orientation of fibers has a significant effect on the thermal conductivity of composites. To validate the experimental results, the heating tests for the thermal conductivity measurements were simulated by a finite element model using the thermal conductivity values obtained from the experiments. Predicted temperatures show close agreement with measured temperatures. Moreover, the experimental results of thermal conductivities of composites at different directions were compared with two theoretical models and illustrated good agreement between the obtained results and models.

From the author: The higher requirements in dosage accuracy and material strength for products with micro features have made the solid conveying process in microinjection molding machines very important. Problems such as starve feeding and process instability will adversely affect quality more in microinjection molding than bigger parts. Studies have been carried out on the conveying of discrete solid polymer pellets in the plasticizing unit of microinjection molding machines using a newly developed discrete element modeling method to simulate polymer particle movements in the screw channel. The model takes into consideration the influences of adhesion and gravity. The effect of inclination of the conveying screw on the speed of solid conveying is investigated with both simulation and experimental approaches. The results of simulations agree with the results of experiments qualitatively. POLYM. ENG. SCI., 46:1608-1612, 2006. [c] 2006 Society of Plastics Engineers

From the author: Two viscoelastic constitutive relations in differential form are further developed here to include material nonlinearity and distinction between loading and unloading regimes, which is a characteristic of polymers. The effects of hydrostatic pressure and anisotropy in tension and compression on the deformation response of polymers are accounted for through the definition of a pressure-dependent equivalent stress. In the uniaxial stress state, these constitutive relations reduce to the two well-known mechanical analogue representations: "Kelvin-Voigt-type" and "Maxwell-type" rheological models. The predictive capabilities of these constitutive relations are then assessed against a wide range of experimental results, which include both uniaxial and biaxial stress states subjected to quasi-static and cyclic-loading conditions. The predictions of both models are found to be in good agreement with the test data. POLYM. ENG. SCI., 47:593-607, 2007. [c] 2007 Society of Plastics Engineers

Book Description

“I often said before starting, that I had no doubt I should frequently repent of the whole undertaking.” So wrote Charles Darwin aboard The Beagle, bound for the Galapagos Islands and what would arguably become the greatest and most controversial discovery in scientific history. But the theory of evolution did not spring full-blown from the head of Darwin. Since the dawn of humanity, priests, philosophers, and scientists have debated the origin and development of life on earth, and with modern science, that debate shifted into high gear.

In this lively, deeply erudite work, Pulitzer Prize–winning science historian Edward J. Larson takes us on a guided tour of Darwin’s “dangerous idea,” from its theoretical antecedents in the early nineteenth century to the brilliant breakthroughs of Darwin and Wallace, to Watson and Crick’s stunning discovery of the DNA double helix, and to the triumphant neo-Darwinian synthesis and rising sociobiology today.

Along the way, Larson expertly places the scientific upheaval of evolution in cultural perspective: the social and philosophical earthquake that was the French Revolution; the development, in England, of a laissez-faire capitalism in tune with a Darwinian ethos of “survival of the fittest”; the emergence of Social Darwinism and the dark science of eugenics against a backdrop of industrial revolution; the American Christian backlash against evolutionism that culminated in the famous Scopes trial; and on to today’s world, where religious fundamentalists litigate for the right to teach “creation science” alongside evolution in U.S. public schools, even as the theory itself continues to evolve in new and surprising directions.

Throughout, Larson trains his spotlight on the lives and careers of the scientists, explorers, and eccentrics whose collaborations and competitions have driven the theory of evolution forward. Here are portraits of Cuvier, Lamarck, Darwin, Wallace, Haeckel, Galton, Huxley, Mendel, Morgan, Fisher, Dobzhansky, Watson and Crick, W. D. Hamilton, E. O. Wilson, and many others. Celebrated as one of mankind’s crowning scientific achievements and reviled as a threat to our deepest values, the theory of evolution has utterly transformed our view of life, religion, origins, and the theory itself, and remains controversial, especially in the United States (where 90% of adults do not subscribe to the full Darwinian vision). Replete with fresh material and new insights, Evolution will educate and inform while taking readers on a fascinating journey of discovery.

Detailed history of an important theory.......2007-08-30

Larson's book is a thorough survey of the figures of history who contributed to the theory of evolution. From 18th century French naturalist Cuvier to modern British biologist Dawkins, this volume details the story and impact of those men, often delving into the religious implications of scientific findings, but focusing on the concepts of evolution itself. While the description of those concepts are sufficient, they aren't exactly stimulating, but the background anecdotes on each contributor give the book color enough. The book is a fascinating look at psychology and sociology as much as biology and would be a good introduction for even theologists due to its fairly subjective nature.

How Darwinism made headway among Christians.......2006-11-23

If, as Edward Larson says, Charles Darwin's "Origin of Species" "dealt a body blow to traditional Western religious thought," then how in the world did it succeed as quickly as it did in a society that was, to put it mildly, staunchly devoted to Christianity?
Larson, a professor of both law and history at the University of Georgia, has been trying to explain that for years. "Evolution" is the third and last volume of that study. The second volume in his saga, "Summer of the Gods," which covered the Scopes "Monkey Trial," won the Pulitzer Prize.
It may come as a surprise to many Americans, especially anti-evolutionists, who typically treat Darwin as having arisen complete, sort of like Athena rising from the head of Zeus, that Biblical creationism was moribund by the time Darwin wrote.
"By 1859," Larson says, "the idea of evolution did not seem as foreign or threatening as it once did to members of Britain's rising elite."
Yet, "by the end of the 19th century, Darwinism was on the ropes."
Nothing evolves faster than evolutionism, and today Darwinism is all triumphant. Unlike, say, cosmology, where there are research programs that are based on views radically different from the prevalent Big Bang explanation, in biology it is all Darwinism.
There is some political agitation for a form of creationism called Intelligent Design, but there is no research program to explore the implications of Intelligent Design, nor does Intelligent Design propose any testable ideas.
Although antidarwinians often allege that Darwinian evolution is "not science" because it does not make testable predictions, this is incorrect.
The biggest prediction, one that mystified Darwin until his death, was that his theory required inheritance of characters to be particulate rather than blending.
That is, a child with a blue-eyed mother and a brown-eyed father would not (always) have green eyes, but (usually) blue or brown.
The discovery of the gene around 1900 provided the mechanism for particulate inheritance. Until then, doubts about Darwinism had begun to conquer the academy.
By 1942, the "modern synthesis" had solved most of the puzzles of "descent with modification," as Darwin had called his idea.
"The synthesis," Larson writes, "generated a seemingly endless stream of testable deductions about how populations should act under controlled conditions and in the wild. Time and again the theory passed these tests."
Although Darwin said he had difficulty in composing the idea of a benevolent god with the observed cruelty of life, Larson opines that, "In practice, acceptance of the modern synthesis coexisted with all manner of religious faith" by the centenary of "Origin" in 1959.
In the generation since, public opinion in America (though not elsewhere) has become increasingly antagonistic to evolution, though no one has been able to mount a credible challenge to the science of it.
Larson is not a controversialist. His "Evolution" is presented, as the subtitle says, as "the remarkable history of a scientific theory." His tale is an evenhanded account of a "theory that ripped through science and society, leaving little unchanged by its force," with both the ups and the downs given thoughtful attention.
If there's a fault to "Evolution" the book, it is that too much is compressed into a mere, though clear, 300 pages.

A Highly Useful Introduction to Evolution.......2006-11-08

Edward Larson's book on Evolution I found to be extremely useful and a valuable resource. Larson is the author of a fine study of the Scopes Trial called "Summer for the Gods." This Modern Library book in its 300 pages is chock full of useful information on this topic. This is not a book just about Darwin, though of course he is the central character, but more about what preceded Darwin and what went on after the Darwinian breakthrough, all the way to the present, in Europe and the U.S. In other words, this book places Darwin within a highly useful framework, what occurred before the "Origin of Species" and what transpired thereafter. An initial chapter focuses on pre-Darwinian developments beginning with the Enlightenment in biology and geology among other fields, including individuals such as Lamarck, Agassiz, Lyell, and Hutton. The next several chapters deal with Darwin and his argument, including the later "Descent of Man." A really superb chapter on the "Ascent of Evolutionism" discusses the debates that ensued after Darwin announced his theory, including non-Darwinian theories of evolution. Subsequent chapters deal with the "missing link" problem; the evolution of genetics; the development of eugenics; and the religious opposition (principally in this country) to evolution, including the Scopes trial and "intelligent design." The book concludes with an analysis of the most current theories relating to evolution, including the tremendous impact of DNA technology. Excellent notes, outstanding illustrations, and Larson once again demonstrates his ability to explain complicated scientific concepts to the layperson--a rare talent. A treasure trove of information on this topic presented in a highly attractive format--i.e., it is just fun to read.

Excellent General History of a Great Idea.......2006-09-06

I can't add a lot to the other reviews here. I encourage you to read some of the other reviews to get a summary of the book's contents - I won't repeat those here. I recommend skipping the couple of reviews that are by people simply pushing an agenda. I applaud the Deacon, who while not believing in evolution, still read the book and gave it a fair and honest review (his review proves that fair-minded people can disagree with an author but still give an intellectually honest evaluation).

I enjoyed the book because it is exactly what it says it is: the history of an idea. It is not a primer on evolution itself. This book would best be read by those who are already familiar with evolution (but not experts) and aware of the broad outlines of the history of the concept of evolution. This book will then provide a concise, enthralling review of the roots of evolution in late 18th, early 19th century thought all the way through to the status of evolutionary thinking today. You don't get an in depth treatment of any one topic, but Larson covers all the major players and sub theories and competing theories in just the right level of detail. If you have read a lot about aspects and episodes in the history of science and evolution, as I have, this book pulls it all together wonderfully.

By comparison, Gould gives a similar "history of evolutionary thinking" in his mammoth _Structure of Evolutionary Theory_. Larson's is far better organized, far clearer, and way more concise than Gould's rambling treatment. Gould's history is interesting and accurate, but much, much harder to get through. The "Notes on Further Reading" at the end of this book is very helpful (though I wish it was even more extensive).

In short, if you are interested in the origins of one of the greatest ideas in human history, or interested in how it battled to preeminence over the last 150 years, this is an excellent choice. Thank you Mr. Larson!

Another Success for the Modern Library Chronicles.......2006-08-12

I really enjoyed this book, as I have all the Modern Library Chronicles that I have read. I am a Christian; moreover, a evangelical, fundamentalist who am a deacon in my church, and I believe that this is a book that high school students (undergrads at least) should read.

In this book, Professor Larson follows the theory of evolution from its earliest beginnings to the modern day. This book reveals the different twists the theory has undergone throughout the years, and points out some of the problems still facing the theory. The book also shows the attacks many have made on the theory, attacks unfortunately based on passion, not science.

From the race between Darwin and Wallace as to who obtained credit for the theory of evolution, Huxley's arguments supporting the theory, Lamark's rise and fall, the Scopes-Monkey Trial to Gould's punctuated equilibrim, this book explains the various twists and theories of evolution is a easy to understand and readable manner; and unlike many treatistes, this book is a readible 368 pages.

This book is exactly what it claims to be; it is a HISTORY of the theory of evolution. If you are looking for a book that denegrates creationists or evolutionists, this is not for you. Neither is this book a strong tool for converting others to believe in evolution.

I still do not believe man evolved, or that one species can become a new species-i.e.-I do not believe in macro-evolution, but I would strongly recommend this book for anyone interested in learing more about the theory of evolution-believer or not.
