From Darwin to Derrida Selfish Genes, Social Selves, and the Meanings of Life - Epub + Converted PDF
نویسندگان: خلاصه: Evolutionary theory can be a nasty business. Perhaps it has something to say about human nature. Most scientifically respectable evolutionary theories wear garments of math. I think of mathematical models as disciplined metaphors. We use x to represent something in the world, say slugs, and y to represent something else, say lettuces, then we analyze the relation of x to y using mathematics. We imagine that slugs and lettuces behave like x and y in the model, and then we use how x and y behave in the model to understand how slugs and lettuces behave in the world. Nobody can argue with mathematical models—that is one of the points of using mathematics—but there can be endless arguments about what you put into a model and what you leave out, and endless arguments about what the model means, because metaphors can be interpreted in many ways. I am not criticizing the use of metaphors—far from it, they are essential. All that we know about the world is metaphor. Our perceptions are a virtual reality, not the thing in itself but something that stands in the place of the thing. Phenomena are metaphors used to comprehend things. Don’t worry, this book contains almost no mathematics; but, if you don’t like metaphor, then this is probably a good time to return the book and ask for a refund.
Deutschland in Grün by Frank Uekötter - PDF
نویسندگان: خلاصه: Das grüne Deutschland hat international unterschiedliche Bewertungen erfahren. Eine freundliche Lesart betont, die Deut- schen hätten ein Niveau des ökologischen Bewusstseins erreicht, von dem sich andere Länder ruhig eine Scheibe abschneiden könnten. Eine weniger freundliche Lesart zieht lieber eine Linie zu den finsteren Kapiteln der deutschen Geschichte, und natür- lich stehen dabei die Nazis an der Spitze der Beliebtheitsskala. Oft stimmen noch nicht einmal die Fakten, und von einer Refle- xion des Gesamtzusammenhangs ist bei solchen Gelegenheiten erst recht keine Rede.6 Während das grüne Deutschland inter- nationale Anerkennung findet, ist seine Geschichte ein Stein- bruch für all jene, denen es vor allem auf eine billige Provokation ankommt.

Design of Injection Molded Plastic Parts - Original PDF
نویسندگان: خلاصه: This book creates a new perspective on the design of plastic parts. In many books there is a strong focus on the material, the material properties, and the calculation or dimensioning. What is often not taken into account is that very many plastic components only have to withstand low loads; in very many applications, the focus is on the actual design. This requires a good understanding of the injection molds that must be built to produce the plastic components. Depending on the design of the injection molded component, these molds become more complex and more prone to failure during production. The complex process of manufacturing a plastic part becomes holistically understandable as a link is created between the molder, the mold maker, and the part designer. The focus is on injection molds and therefore on thermoplastics. Everything that is necessary for the design and manufacture of an injection molded component is presented in a simple, extremely practical manner and limited to the essentials. Many descriptive pictures as well as examples based on the demonstration component "Polyman" facilitate the understanding enormously.

Messages, Signs, and Meanings: A Basic Textbook in Semiotics and Communication - Original PDF
نویسندگان: خلاصه: This text is designed to provide a basic introduction to semiotics and communication theory, with plenty of examples from, and applications to, popular culture. It aims to make accessible the technical and often abstruse subject matter of sign theory in practical ways, with illustrations in such areas as myth. storytelling, television, advertising, clothing, and architecture. Without overwhelming, this introduction allows students and interested general readers to get a comprehensive look at what semiotics and communication theory are all about. Messages, Signs, and Meanings can be used directly in introductory courses in semiotics, communications, media, or culture studies. Additionally, it can be used in courses dealing with cognate areas of investigation (psychology, mythology, education, literary studies, anthropology, linguistics) as a complementary or supplementary text. The text builds upon what readers already known intuitively about signs and then leads them to think critically about the world in which they live--a world saturated with images of all kinds that a basic knowledge of semiotics can help filter and deconstruct. The text also provides opportunities for readers to do ''hands-on'' semiotics through the exercises and questions for discussion that accompany each chapter. Biographical sketches of the major figures in the field are also included, as is a convenient glossary of technical terms. The overall plan of the book is to illustrate how message-making and meaning-making can be studied from the specific vantage point of the discipline of semiotics. This third edition also includes updated discussions of information technology throughout, focusing especially on howmeanings are now negotiated through such channels as websites. chat rooms, and instant messages.
