Publisher description

In Magnetic Current, Edward Leedskalnin presents his groundbreaking theories on the nature of magnetism and its relationship to electricity. Through a series of experiments and observations, Leedskalnin challenges conventional understanding of these fundamental forces, offering a unique perspective on the workings of the universe. This book is a must-read for anyone interested in alternative scientific theories and the mysteries of the natural world.

The latest ideas in machine analysis and design have led to a major revision of the field's leading handbook. New chapters cover ergonomics, safety, and computer-aided design, with revised information on numerical methods, belt devices, statistics, standards, and codes and regulations. Key features include: *new material on ergonomics, safety, and computer-aided design; *practical reference data that helps machines designers solve common problems--with a minimum of theory. *current CAS/CAM applications, other machine computational aids, and robotic applications in machine design. This definitive machine design handbook for product designers, project engineers, design engineers, and manufacturing engineers covers every aspect of machine construction and operations. Voluminous and heavily illustrated, it discusses standards, codes and regulations; wear; solid materials, seals; flywheels; power screws; threaded fasteners; springs; lubrication; gaskets; coupling; belt drive; gears; shafting; vibration and control; linkage; and corrosion.

Since 'The Social Logic of Space' was published in 1984, Bill Hillier and his colleagues at University College London have been conducting research on how space features in the form and functioning of buildings and cities. A key outcome is the concept of 'spatial configuration' meaning relations which take account of other relations in a complex. New techniques have been developed and applied to a wide range of architectural and urban problems. The aim of this book is to assemble some of this work and show how it leads to a new type of theory of architecture, an analytic theory in which understanding and design advance together. The success of configurational ideas in bringing to light the spatial logic of buildings and cities suggests that it might be possible to extend these ideas to other areas of the human sciences where problems of configuration are critical.

Dr. Greg Zacharias, former Chief Scientist of the United States Air Force (2015-18), explores next steps in autonomous systems (AS) development, fielding, and training. Rapid advances in AS development and artificial intelligence (AI) research will change how we think about machines, whether they are individual vehicle platforms or networked enterprises. The payoff will be considerable, affording the US military significant protection for aviators, greater effectiveness in employment, and unlimited opportunities for novel and disruptive concepts of operations. Autonomous Horizons: The Way Forward identifies issues and makes recommendations for the Air Force to take full advantage of this transformational technology.

From farmer Joel Salatin's point of view, life in the 21st century just ain't normal. In FOLKS, THIS AIN'T NORMAL, he discusses how far removed we are from the simple, sustainable joy that comes from living close to the land and the people we love. Salatin has many thoughts on what normal is and shares practical and philosophical ideas for changing our lives in small ways that have big impact. Salatin, hailed by the New York Times as "Virginia's most multifaceted agrarian since Thomas Jefferson [and] the high priest of the pasture" and profiled in the Academy Award nominated documentary Food, Inc. and the bestselling book The Omnivore's Dilemma, understands what food should be: Wholesome, seasonal, raised naturally, procured locally, prepared lovingly, and eaten with a profound reverence for the circle of life. And his message doesn't stop there. From child-rearing, to creating quality family time, to respecting the environment, Salatin writes with a wicked sense of humor and true storyteller's knack for the revealing anecdote. Salatin's crucial message and distinctive voice--practical, provocative, scientific, and down-home philosophical in equal measure--make FOLKS, THIS AIN'T NORMAL a must-read book.
