The Principle of Least Action: History and Physics
The principle of least action originates in the idea that, if nature has a purpose, it should follow a minimum or critical path. This simple principle, and its variants and generalizations, applies to optics, mechanics, electromagnetism, relativity, and quantum mechanics, and provides an essential guide to understanding the beauty of physics. This unique text provides an accessible introduction to the action principle across these various fields of physics, and examines its history and fundamental role in science. It includes – with varying levels of mathematical sophistication – explanations from historical sources, discussion of classic papers, and original worked examples. The result is a story that is understandable to those with a modest mathematical background, as well as to researchers and students in physics and the history of physics.

Forensic scientists apply scientific analysis in a legal context and play a vital role in solving crimes. Sometimes the collection of forensic evidence is the only way to establish or exclude an association between suspect and victim or crime scene, or to establish a likely order of events. Profiting from recent scientific developments and the advancement of technological equipment, forensic science is a rapidly evolving discipline that encompasses many sciences and the law. This dictionary covers in over 1300 entries the key concepts within forensic science, including a wide array of relevant specialist terms from areas such as chemistry, biology, anthropology, art, engineering, firearms, toolmarks, trace evidence, crime scene investigation, case history, biographies of investigators and criminals, as well as forensic computing. Ranging from crime scene to fibers and fluorescence to RAM, this new dictionary is the most up-to-date of its kind and is international in scope. Entry-level web links to online resources are listed and regularly updated on a companion website, expanding the scope of the dictionary and pointing to more in-depth supplementary material. Many entries are complemented by case examples (Dr Crippen, Mary Ann Cotton, etc.), figures, and photographs, which makes this A to Z an ideal reference for students of forensic science, as well as professionals and those with an interest in forensics.
Measurement is an essential activity in every branch of technology and science and as such forms part of degree, diploma and certificate courses in engineering and applied science.The fourth edition of this respected and successful text has been extensively extended and updated to include new developments in measurement devices and technology. It provides a coherent and integrated approach to the topic, covering main techniques and devices used, together with relevant theory and applications, for both mechanical and electronic systems.~It is divided into three parts, covering the general principles, followed by the typical elements of measurement systems, and then moving on to current and emerging specialised techniques which have important industrial applications. ~Key features:*New chapter on Intelligent Multivariable Measurement Systems *Incorporates increased coverage on solid state sensors*New material on structure, software and applications of microcontrollers*A completely revised chapter on Data Presentation*Additional problems have been added at a basic and introductory level*Solutions manual~This book is aimed at students taking modules in measurement and instrumentation as part of degree courses in instrumentation/control, mechanical, manufacturing, electrical, electronic, chemical engineering and applied physics as well as students on HNC/HND and foundation degree courses on measurement and instrumentation. This text is also suitable for professional and technical engineers working in the measurement and control discipline.~John P. Bentley is Emeritus Professor of Measurement Systems at the University of Teesside
Thoroughly updated for currency and with exciting new practical examples throughout, this popular text provides the tools, practice, and basic knowledge for success in the biotech workforce. With its balanced coverage of basic cell and molecular biology, fundamental techniques, historical accounts, new advances, and hands-on applications, the Third Edition emphasizes the future of biotechnology and the biotechnology student’s role in that future. Two new features-Forecasting the Future, and Making a Difference-along with several returning hallmark features, support the new focus.
The Science Matrix is a comprehensive new compact course book covering all 24 of the content-based NCEA level 1 Science, Biology, Chemistry and Physics standards (as specified in NZQA’s subject matrix) in just over 200 pages. For whatever combination of standards you choose to offer students in your Year 11 here is a single affordable textbook that covers the knowledge, understandings and skills your students require for success in both externally and internally assessed NCEA standards. Building on the long-term appeal of the Pathfinder unit format, George Hook has written numerous new units and updated existing ones to cover all bullet points of the new standards. The units closely reflect the current expectations and requirements of NCEA examiners and assessors.
