Book Description
In this book I share details about many different resultants. I have included some stories about my own near misses, while working with these resultant forces; some of which nearly took my life. I also share other situations, where resultants have hurt and killed others.I have found having this knowledge about these resultants has helped me do everything from change a fuel filter, to get a water heater (full of water) up a narrow stairway and outside, to saving lives. This includes engineering special effects for movies and TV commercials, to bolting boulders weighing many hundreds of tons, to the side of a mountain, so it would not fall on others, to rescuing people from precarious places - "resultants are all around us."Whether you are a Seasoned Professional, interested in expanding your knowledge and skills, or someone interested in learning more about the world around us, you find reading this text is an investment in efficiency, safety, ideas, survival and additional skills, and much more. It can earn you money, make your job easier, or it could save your life, or someone else's life.Thanks again and please do enjoy . . .Douglas S. Hansen

Book Description
Pulley Systems Explained has evolved into a full 300 dpi color book, with more than 280 pages. It includes many more diagrams, drawings, examples, pictures, and applications. It explains the difference between simple, complex pulley systems, and how compounding effect works, how to determine the pulley advantage of any pulley system, ways to use them at work, for rescue, or while on an adventure. Including a special section of applications, strategies, and tactics. A sampling of many situations we run into while working in real life. It teaches skills, and helps prepare you to handle those complex situations we all must deal with, yet there is no simple answer. I share other related things that 40 years of "walking the talk" has brought. ♦"Book knowledge is good information, combine training, and it becomes usable knowledge, add experience and you have the pure gold of knowledge." This is the "Pulley Section" of the "Ropes, Pulleys, Rigging Systems, and Avoiding Dangerous Resultants Book Series. "Pulley Systems Explained" is the evolution of many years of writing, collecting, drawing, taking pictures, working with other professionals, rewriting, organizing, and fine tuning articles and books about Ropes, Pulleys, Rigging System, and Safety (Avoiding Dangerous Resultants). Rope is one of the most common simple machines, add pulleys and we now have a system. This book if full of systems you can use at work, during rescues, and at home, or while on adventures. There are examples, challenges, quizzes, charts, diagrams, and pictures, and more ways we can work with pulleys to make our lives better. "Maximum Efficiency and Simplicity with a Minimum of Effort and Equipment; while maintaining low risk exposure." It defines an approach to assembling our systems. Pulley Systems Explain is also a good companion book to use with ®vRigger Software for learning various pulley rigging systems.

Book Description
Jerry Thigpen's study on the history of the Combat Talon is the first effort to tell the story of this wonderfully capable machine. This weapons system has performed virtually every imaginable tactical event in the spectrum of conflict and by any measure is the most versatile C-130 derivative ever produced. First modified and sent to Southeast Asia (SEA) in 1966 to replace theater unconventional warfare (UW) assets that were limited in both lift capability and speed the Talon I quickly adapted to theater UW tasking including infiltration and resupply and psychological warfare operations into North Vietnam. After spending four years in SEA and maturing into a highly respected UW weapons system the Joint Chief of Staff (JCS) chose the Combat Talon to lead the night low-level raid on the North Vietnamese prison camp at Son Tay. Despite the outcome of the operation the Talon I cemented its reputation as the weapons system of choice for long-range clandestine operations. In the period following the Vietnam War United States Air Force (USAF) special operations gradually lost its political and financial support which was graphically demonstrated in the failed Desert One mission into Iran. Thanks to congressional supporters like Earl Hutto of Florida and Dan Daniel of Virginia funds for aircraft upgrades and military construction projects materialized to meet the ever-increasing threat to our nation. Under the leadership of such committed hard-driven officers as Brenci Uttaro Ferkes Meller and Thigpen the crew force became the most disciplined in our Air Force. It was capable of penetrating hostile airspace at night in a low-level mountainous environment covertly to execute any number of unconventional warfare missions.

Book Description
“YOU HAVE CHANGED MY LIFE” is a common refrain in the emails Walter Lewin receives daily from fans who have been enthralled by his world-famous video lectures about the wonders of physics. “I walk with a new spring in my step and I look at life through physics-colored eyes,” wrote one such fan. When Lewin’s lectures were made available online, he became an instant YouTube celebrity, and The New York Times declared, “Walter Lewin delivers his lectures with the panache of Julia Child bringing French cooking to amateurs and the zany theatricality of YouTube’s greatest hits.” For more than thirty years as a beloved professor at the Massachusetts Institute of Technology, Lewin honed his singular craft of making physics not only accessible but truly fun, whether putting his head in the path of a wrecking ball, supercharging himself with three hundred thousand volts of electricity, or demonstrating why the sky is blue and why clouds are white. Now, as Carl Sagan did for astronomy and Brian Green did for cosmology, Lewin takes readers on a marvelous journey in For the Love of Physics, opening our eyes as never before to the amazing beauty and power with which physics can reveal the hidden workings of the world all around us. “I introduce people to their own world,” writes Lewin, “the world they live in and are familiar with but don’t approach like a physicist—yet.” Could it be true that we are shorter standing up than lying down? Why can we snorkel no deeper than about one foot below the surface? Why are the colors of a rainbow always in the same order, and would it be possible to put our hand out and touch one? Whether introducing why the air smells so fresh after a lightning storm, why we briefly lose (and gain) weight when we ride in an elevator, or what the big bang would have sounded like had anyone existed to hear it, Lewin never ceases to surprise and delight with the extraordinary ability of physics to answer even the most elusive questions. Recounting his own exciting discoveries as a pioneer in the field of X-ray astronomy—arriving at MIT right at the start of an astonishing revolution in astronomy—he also brings to life the power of physics to reach into the vastness of space and unveil exotic uncharted territories, from the marvels of a supernova explosion in the Large Magellanic Cloud to the unseeable depths of black holes. “For me,” Lewin writes, “physics is a way of seeing—the spectacular and the mundane, the immense and the minute—as a beautiful, thrillingly interwoven whole.” His wonderfully inventive and vivid ways of introducing us to the revelations of physics impart to us a new appreciation of the remarkable beauty and intricate harmonies of the forces that govern our lives.
