Crystal Clear: The Struggle for Reliable Communications Technology in World War II
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.

Industry Regulation and the Performance of the American Economy by Paul W. MacAvoy, ISBN 0393961869
Regulation reached its zenith in the 1960s. The 1980s was the decade of deregulation. The 1990s afford us an important opportunity to assess what is left of regulation and its impact on the economy. And who better to do this than Paul W. MacAvoy, one of America's most respected experts on the economics of industry? Beginning with the Act to Regulate Commerce of 1887, Professor MacAvoy traces the rise of regulation over one hundred years to its sharp curtailment in the 1980s. Originally invoked as a means of controlling the prices set by monopolies, this policy tool found extended use in the last quarter-century to do everything from keeping down energy prices to protecting the health and safety of workers and the quality of the environment. In most cases regulation has been founded on the best of intentions, but as the deregulation of the airline, trucking, and railroad industries in the 1980s made clear there are other ways of achieving social objectives. It is thus useful to ask whether...

Stagecoach West by Ralph Moody, ISBN 0803282451
Stagecoach West is a comprehensive history of stagecoaching west of the Missouri. Starting with the evolution of overland passenger transportation, Moody moves on to paint a lively and informative picture of western stagecoaching, from its early short runs through its rise with the gold rush, its zenith of 1858-68 and beyond. Its story is one of grand rivalries, political chicanery, and gaudy publicity stunts, traders, fortune hunters, outlaws, courageous drivers, and indefatigable detectives. We meet colorful characters such as Charlie Parkhurst, a stagecoach driver who took an amazing secret to his death: "he" was actually a woman. Using contemporary accounts, illustrations, maps, and photographs to flesh out his narrative, Moody creates one of the most important accounts of transportation history to date.
