Why did the Greeks excel in geometry, but lag begin the Mesopotamians in arithmetic? How were the great pyramids of Egypt and the Han tombs in China constructed? What did the complex system of canals and dykes in the Tigris and Euphrates river valley have to do with the deforestation of Lebanon's famed cedar forests? This work presents a cross-cultural comparison of the ways in which the ancients learned about and preserved their knowledge of the natural world, and the ways in which they developed technologies that enabled them to adapt to and shape their surroundings. Covering the major ancient civilizations - those of Mesopotamia, Egypt, China, Greece, the Indus Valley, and Meso-America - Olson explores how language and numbering systems influenced the social structure, how seemingly beneficial construction projects affected a civilization's rise or decline, how religion and magic shaped both medicine and agriculture, and how trade and the resulting cultural interactions transformed the making of both everyday household items and items intended as art. Along the way, Olson delves into how scientific knowledge and its technological applications changed the daily lives of the ancients.

This new, retitled, edition of Fibre Failure and Wear of Materials has been updated and expanded to include more examples from work at UMIST (University of Manchester Institute of Science and Technology) in the 1990s and to take account of recent research elsewhere. It contains over 500 new micrographs to add to the 1,000 in the first edition and includes two new sections on forensic and medical studies. Based on over 25 years of research at UMIST, the book is concerned with how fibres fail under stress. Until comparatively recently little was known about the way in which fibres break. In this book about 20 different modes of fibre failure are examined. Case studies have been selected both from the traditional uses of textiles in clothing and in household products, such as sheets, towels and carpets and also from the study of failure in textile structures used in industry and engineering, for example seat belts and ropes. This unique collection of more than 1500 scanning electron micrographs and other pictures for identifying failure modes, together with the accompanying explanatory text, provides fibre scientists, polymer scientists and others working in textile research with a better understanding of fracture mechanisms. The book will also be of interest to forensic scientists and medical specialists using fibre implants. Finally, it will help textile technologists and design engineers to manufacture improved textile products and to use them in ways which will maximise their life span.

Design and Analysis of Experiments with R presents a unified treatment of experimental designs and design concepts commonly used in practice. It connects the objectives of research to the type of experimental design required, describes the process of creating the design and collecting the data, shows how to perform the proper analysis of the data, and illustrates the interpretation of results. Drawing on his many years of working in the pharmaceutical, agricultural, industrial chemicals, and machinery industries, the author teaches students how to: Make an appropriate design choice based on the objectives of a research project Create a design and perform an experiment Interpret the results of computer data analysis The book emphasizes the connection among the experimental units, the way treatments are randomized to experimental units, and the proper error term for data analysis. R code is used to create and analyze all the example experiments. The code examples from the text are available for download on the author’s website, enabling students to duplicate all the designs and data analysis. Intended for a one-semester or two-quarter course on experimental design, this text covers classical ideas in experimental design as well as the latest research topics. It gives students practical guidance on using R to analyze experimental data.
