What do nails, hammers, axes, and human teeth have in common? They're all examples of wedges. This fascinating simple machine takes many important forms that shape how humans interact with the world. This innovative book introduces readers to real-world examples of the wedge and thoroughly explains how this tool works. Detailed pictures with extensive annotations explain essential engineering concepts. "Technology in Action" spreads give readers an inside look at wedges in action. This accessible book introduces readers to simple machines in a fun way, encouraging an early interest in STEM.

A wedge is two inclined planes joined together. When joined, the inclined planes form a sharp edge. Inclined planes are stationary objects, whereas wedges are active objects. When force is applied to the flat side of the wedge opposite the sharp edge, parts of the object become separated. For example, an ax is a metal wedge that splits a piece of wood apart. Readers will be provided with a number of examples of wedges, where they're found, and the wedge's historical uses.

The book has a dual purpose. The first is to expose a general methodology to solve problems of electromagnetism in geometries constituted of angular regions. The second is to bring the solutions of some canonical problems of fundamental importance in modern electromagnetic engineering with the use of the Wiener-Hopf technique. In particular, the general mathematical methodology is very ingenious and original. It is based on sophisticated and attractive procedures exploiting simple and advanced properties of analytical functions. Once the reader has acquired the methodology, she/he can easily obtain the solution of the canonical problems reported in the book. The book can be appealing also to readers who are not directly interested in the detailed mathematical methodology and/ or in electromagnetics. In fact the same methodology can be extended to acoustics and elasticity problems. Moreover, the proposed practical problems with their solutions constitute a list of reference solutions and can be of interests in engineering production in the field of radio propagations, electromagnetic compatibility and radar technologies.

As towns and cities worldwide deal with fast-increasing land pressures, while also trying to promote more sustainable, connected communities, the creation of green spaces within urban areas is receiving greater attention than ever before. At the same time, the value of the 'green belt' as the most prominent model of green space planning is being widely questioned, and an array of alternative models are being proposed. This book explores one of those alternative models – the 'green wedge', showing how this offers a successful model for integrating urban development and nature in existing and new towns and cities around the world. Green wedges, considered here as ducts of green space running from the countryside into the centre of a city or town, are not only making a comeback in urban planning, but they have a deeper history in the twentieth century than many expect – a history that provides valuable insight and lessons in the employment of networked green spaces in city design and regional planning today. Part history, and part contemporary argument, this book first examines the emergence and global diffusion of the green wedge in town planning in the late 19th and early 20th centuries, placing it in the broader historic context of debates and ideas for urban planning with nature, before going on to explore its use in contemporary urban practice. Examining their relation to green infrastructures, landscape ecology and landscape urbanism and their potential for sustainable cities, it highlights the continued relevance of a historic idea in an era of rapid climate change.

Short game shots in your golf game don't have to be complicated-unless you're getting all kinds of conflicting information about technique and strategy. In The Wedge Book, Brandon Stooksbury cuts through the confusion and provides you a clear, straightforward plan to build your short game from the smallest bump-and-run to a 50-yard pitch shot. By using the same baseline technique and adding specific elements for certain shots, you'll be able to take away the mystery and indecision that can ruin a golf hole so easily. Stooksbury's advice has been proven in the highest levels of competitive golf. And now, with The Wedge Book-and a month or so of practice-you can take it to your course.
