Most of the shaping in the manufacture of polymeric objects is carried out in the melt state, as it is a substantial part of the physical property development. Melt processing involves an interplay between fluid mechanics and heat transfer in rheologically complex liquids, and taken as a whole it is a nice example of the importance of coupled transport processes. This book is on the underlying foundations of polymer melt processing, which can be derived from relatively straightforward ideas in fluid mechanics and heat transfer; the level is that of an advanced undergraduate or beginning graduate course, and the material can serve as the text for a course in polymer processing or for a second course in transport processes.

A collection of essays covering a variety of scientific topics including the nature of technology to the human body, evolution, and ecology.

Biotechnology (BT) offers exciting and promising prospects for healing the sick and relieving the suffering. But because of their impressive powers to alter the workings of body and mind, the "dual uses" of the same technologies make them attractive also to people who are not sick but who would use them to look younger, perform better, feel happier, or become more "perfect." These applications of BT present us with difficult challenges. This report considers such possible "beyond therapy" uses and explores both their scientific basis and the ethical and social issues they will raise. In enjoying the benefits of BT, we will need to hold fast to an account of the human being, seen not in material or mechanistic or med. terms, but in psychic and moral and spiritual ones.

"If a science has to be supported by fraudulent means, let it perish. " With these words of Kepler, Agassi plunges into the actual troubles and glories of science (321). The SOciology of science is no foreign intruder upon scientific knowledge in these essays, for we see clearly how Agassi transforms the tired internalistJexternalist debate about the causal influences in the history of science. The social character of the entire intertwined epistemological and practical natures of the sciences is intrinsic to science and itself split: the internal sociology within science, the external sociology of the social setting without. Agassi sees these social matters in the small as well as the large: from the details of scientific communication, changing publishing as he thinks to 'on-demand' centralism with less waste (Ch. 12), to the colossal tension of romanticism and rationality in the sweep of historical cultures. Agassi is a moral and political philosopher of science, defending, dis turbing, comprehending, criticizing. For him, science in a society requires confrontation, again and again, with issues of autonomy vs. legitimation as the central problem of democracy. And furthermore, devotion to science, pace Popper, Polanyi, and Weber, carries preoccupational dangers: Popper's elitist rooting out of 'pseudo-science', Weber's hard-working obsessive . com mitment to science. See Agassi's Weberian gloss on the social psychology of science in his provocative 'picture of the scientist as maniac' (437).

Nearly forty of the world's most esteemed scientists discuss the big questions that drive their illustrious careers. Co-editor Eduardo Punset—one of Spain's most loved personages for his popularization of the sciences—interviews an impressive collection of characters drawing out the seldom seen personalities of the world's most important men and woman of science. In Mind, Life and Universe they describe in their own words the most important and fascinating aspects of their research. Frank and often irreverent, these interviews will keep even the most casual reader of science books rapt for hours. Can brain science explain feelings of happiness and despair? Is it true that chimpanzees are just like us when it comes to sexual innuendo? Is there any hard evidence that life exists anywhere other than on the Earth? Through Punset's skillful questioning, readers will meet one scientist who is passionate about the genetic control of everything and another who spends her every waking hour making sure African ecosystems stay intact. The men and women assembled here by Lynn Margulis and Eduardo Punset will provide a source of endless interest. In captivating conversations with such science luminaries as Jane Goodall, James E. Lovelock, Oliver Sachs, and E. O. Wilson, Punset reveals a hidden world of intellectual interests, verve, and humor. Science enthusiasts and general readers alike will devour Mind, Life and Universe, breathless and enchanted by its truths.

Earth as a cosmic seed is a biosphere. This book is about the concentric layers of experience at the Earth's surface, and the way the past gets tangled up in the present.

”What purpose is served by showing that England's greatest natural philosopher is flawed … like other mortals?” asks one of the characters in Newton's Darkness. “We need unsullied heroes ” But what if the hero is sullied? At stake is an issue that is as germane today as it was 300 years ago: a scientist's ethics must not be divorced from scientific accomplishments. There is probably no other scientist of whom so many biographies and other historical analyses have been published than Isaac Newton — all of them in the standard format of documentary prose because of their didactic purpose to transmit historical information. Newton's Darkness, however, illuminates the darker aspects of Newton's persona through two historically grounded plays dealing with two of the bitterest struggles in the history of science.The name of Isaac Newton appears in virtually every survey of the public's choice for the most important persons of the second millennium. Yet the term “darkness” can be applied to much of Newton's personality. Adjectives that have been used to describe facets of his personality include “remote”, “lonely”, “secretive”, “introverted”, “melancholic”, “humorless”, “puritanical”, “cruel”, “vindictive” and, perhaps worst of all, “unforgiving”. The trait most relevant to the present book is Newton's obsessively competitive nature, which was often out of proportion to the warranted facts, as demonstrated in three of Newton's best-known bitter conflicts: with the physicist Robert Hooke, the astronomer royal John Flamsteed, and a German contemporary of almost equal intellectual prowess, Gottfried Wilhelm Leibniz — the last fight eventually turning into an England vs Continental Europe competition. It is two of these three relentless drawn-out battles that are illuminated in Newton's Darkness in the form of historically grounded drama.After a summary of the historical evidence, the book starts with the Newton-Hooke struggle (Chapter 2), which was conducted mano a mano, and is then followed by little-known aspects of the Newton-Leibniz confrontation (Chapter 3), which was fought largely through surrogates — notably the infamous, anonymous committee of 11 Fellows of the Royal Society.

Professor Joseph Agassi has published his Towards an Historiography of Science in 1963. It received many reviews by notable academics, including Maurice Finocchiaro, Charles Gillispie, Thomas S. Kuhn, Geroge Mora, Nicholas Rescher, and L. Pearce Williams. It is still in use in many courses in the philosophy and history of science. Here it appears in a revised and updated version with responses to these reviews and with many additional chapters, some already classic, others new. They are all paradigms of the author’s innovative way of writing fresh and engaging chapters in the history of the natural sciences.

History of Science

"America's most interesting and important essayist." --Eric Kandel, Nobel Prize-winning author of The Age of Insight "[Gerald Weissmann] bridges the space between science and the humanities, and particularly between medicine and the muses, with wit, erudition, and, most important, wisdom." --Adam Gopnik Epigenetics, which attempts to explain how our genes respond to our environment, is the latest twist on the historic nature vs. nurture debate. In addressing this and other controversies in contemporary science, Gerald Weissmann taps what he calls "the social network of Western Civilization," including the many neglected women of science: from the martyred Hypatia of Alexandria, the first woman scientist, to the Nobel laureates Marie Curie, Christiane Nüsslein-Volhard, and Elizabeth Blackburn, among other luminaries in the field. Always instructive and often hilarious, this is a one-volume introduction to modern biology, viewed through the lens of contemporary mass media and the longer historical tradition of the Scientific Revolution. Whether engaging in the healthcare debate or imagining the future prose styling of the scientific research paper in the age of Twitter, Weissmann proves himself as an incisive cultural critic and satirist. Gerald Weissmann (August 7, 1930 - July 10, 2019) was a physician, scientist, editor, and essayist whose collections include The Fevers of Reason: New and Selected Essays ; Epigenetics in the Age of Twitter: Pop Culture and Modern Science ; Mortal and Immortal DNA: Science and the Lure of Myth ; and Galileo's Gout: Science in an Age of Endarkenment .

Scientific facts can be so complicated that only specialists in a field fully appreciate the details, but the nature of everyday practice that gives rise to these facts should be understandable by everyone interested in science. This book describes how scientists bring their own interests and passions to their work, illustrates the dynamics between researchers and the research community, and emphasizes a contextual understanding of science in place of the linear model found in textbooks with its singular focus on “scientific method.” Everyday Practice of Science also introduces readers to issues about science and society. Practice requires value judgments: What should be done? Who should do it? Who should pay for it? How much? Balancing scientific opportunities with societal needs depends on appreciating both the promises and the ambiguities of science. Understanding practice informs discussions about how to manage research integrity, conflict of interest, and the challenge of modern genetics to human research ethics. Society cannot have the benefits of research without the risks. The last chapter contrasts the practices of science and religion as reflective of two different types of faith and describes a holistic framework within which they dynamically interact.
