Crystal Clear: The Struggle for Reliable Communications Technology in World War II By Richard J. Thompson(auth.)

Quartz crystal-a technology that changed the tide of World War II Some of the defining leaps in technology in the twentieth century occurred during the Second World War, from radar to nuclear energy. Often left out of historical discussions are quartz crystals, which proved to be just as pivotal to the Allied victory-and to post-war development-as other technologies. Quartz crystals provided the U.S. military, for the first time, with reliable communication on the front lines, and then went on to become the core of some of the most basic devices of the post-war era, from watches, clocks, and color televisions, to cell phones and computers. In Crystal Clear, Richard Thompson relates the story of the quartz crystal in World War II, from its early days as a curiosity for amateur radio enthusiasts, to its use by the United States Armed Forces. It follows the intrepid group of scientists and engineers from the Office of the Chief Signal Officer of the U.S. Army as they raced to create an effective quartz crystal unit. They had to find a reliable supply of radio-quality quartz; devise methods to reach, mine, and transport the quartz; find a way to manufacture quartz crystal oscillators rapidly; and then solve the puzzling "aging problem" that plagued the early units. Ultimately, the development of quartz oscillators became the second largest scientific undertaking in World War II after the Manhattan Project. Bringing to light a little-known aspect of World War II, Crystal Clear offers a glimpse inside one of the most significant efforts in the annals of engineering.Content: Chapter 1 From Wire to Wireless: The Development-and Acceptance-of Tactical Radio (pages 5-15): Chapter 2 Crystal Control-The Great Gamble (pages 17-29): Chapter 3 The Signal Corps Lays the Foundation (pages 31-54): Chapter 4 Nothing Else to Do but Grind Crystals (pages 55-68): Chapter 5 Riding the "Flat Wheel Limited"-Overseeing a Mass Production Industry (pages 69-91): Chapter 6 Supplying a Mass Production Industry-The Civilian Government Steps In (pages 93-115): Chapter 7 "The Whole Radio Crystal Program of the Armed Services Depends Upon the Success of the Procurement Program in Brazil.

The book is a gentle self-help guide filled with practical self-care practices which engage the griever into embracing and expressing their grief. Through the gentle practices, the griever can try to find inner peace and begin to heal his/her grieving heart.After a loss, grievers often feel isolated and find it difficult to reach out for help, carrying their pain in silence and alone. Each practice described in the book has been carefully chosen to shine light on areas that are likely to arise as the grieving and healing journey unfolds, and have been organised to make it easy for the reader to choose a path they feel drawn to at any particular moment.
