When darkness falls, storms rage, fog settles, or lights fail, pilots are forced to make "instrument landings," relying on technology and training to guide them through typically the most dangerous part of any flight. In this original study, Erik M. Conway recounts one of the most important stories in aviation history: the evolution of aircraft landing aids that make landing safe and routine in almost all weather conditions. Discussing technologies such as the Loth leader-cable system, the American National Bureau of Standards system, and, its descendants, the Instrument Landing System, the MIT-Army-Sperry Gyroscope microwave blind landing system, and the MIT Radiation Lab's radar-based Ground Controlled Approach system, Conway interweaves technological change, training innovation, and pilots' experiences to examine the evolution of blind landing technologies. He shows how systems originally intended to produce routine, all-weather blind landings gradually developed into routine instrument-guided approaches. Even so, after two decades of development and experience, pilots still did not want to place the most critical phase of flight, the landing, entirely in technology's invisible hand. By the end of World War II, the very concept of landing blind therefore had disappeared from the trade literature, a victim of human limitations.

Have you ever wondered how stealth planes achieve "invisibility," how sunken ships are found, or how fishermen track schools of fish in vast expanses of ocean? Radar and sonar echolocation—a simple matter of sending, receiving, and processing signals. Weaving history with simple science, Mark Denny deftly reveals the world of radar and sonar to the curious reader, technology buff, and expert alike. He begins with an early history of the Chain Home radar system used during World War II and then provides accessible and engaging explanations of the physics that make signal processing possible. Basic diagrams and formulas show how electromagnetic and sound waves are transmitted, received, and converted into images, allowing you to literally see in the dark. A section on bioacoustic echolocation, with a focus on the superior sonar systems of bats and whales and a discussion of the advanced technology of next-generation airborne signal processors, opens the imagination to fascinating possibilities for the future.

In a dazzling tribute to the Texas coast, conservationist and lawyer Jim Blackburn has teamed with photographer Jim Olive to give us the most intimate and important portrait yet of Texas bays and of those who work for their wise use and preservation. While giving life and sustenance to plants, animals, and people, the bays and estuaries of Texas have other stories to tell—about freshwater inflows, deep port construction, disappearing oyster beds, beach resorts, industrial pollution, and more. At a certain point, each story brings opposing forces into the courtroom for vigorous debates on the future of some of our most valuable and irreplaceable resources. The Book of Texas Bays is a personal account of legal battles won and lost, but it is also a fine work of natural history by someone who has a deep spiritual connection to the Texas coast and all it has to offer. Jim Olive’s stunning photographs present us with a dramatic perspective of our relationship with the Gulf and remind us of both the grandness and the fragility of our coastal treasures.

Ranging from alchemy to necromancy, books of secrets? offered medieval readers an affordable and accessible collection of knowledge about the natural world. Allison Kaveys study traces the cultural relevance of these books and also charts their influence on the people who read them. Citing the importance of printers in choosing the books contents, she points out how these books legitimized manipulating nature, thereby expanding cultural categories, such as masculinity, femininity, gentleman, lady, and midwife, to include the willful command of the natural world.

Does a glass of ice water filled to the brim overflow when the ice melts? Does the energy inside a sauna increase when you heat it up? What's the best way to cool your coffee—adding the creamer first or last? These and other challenging puzzlers provide a fresh—and fun—approach to learning real physics. Presenting both classic and new problems, Brainteaser Physics challenges readers to use imagination and basic physics principles to find the answers. Göran Grimvall provides detailed and accessible explanations of the solutions, sometimes correcting the standard explanations, sometimes putting a new twist on them. He provides diagrams and equations where appropriate and ends each problem by discussing a specific concept or offering an extra challenge. With Brainteaser Physics, students and veteran physicists alike can sharpen their critical and creative thinking—and have fun at the same time.

From sixteenth-century cabinets of wonder and Victorian bird collections to stuffed pets and contemporary animal art, Taxidermy and Longing explores the cultural and poetic history of preserving animals in lifelike postures. While death is what makes taxidermy possible, taxidermy is not motivated by brutality but rather by longing for connection within the natural world – a longing for wonder, beauty, spectacle, order, narrative, allegory, and remembrance. Sometimes the most unlikely things offer the most eloquent commentaries.

Most closely associated today with the Nazis and World War II atrocities, eugenics is sometimes described as a government-orchestrated breeding program, other times as a pseudo-science, and often as the first step leading to genocide. Less frequently is it depicted as a movement having links to the United States. But eugenics does have a history in this country, and Mark Largent tells that story by exploring one of the most disturbing aspects, the compulsory asterilization of more than 64,000 Americans.

Heralded by Soviet propaganda as the “Path to the Future,” the Baikal-Amur Mainline Railway (BAM) represented the hopes and dreams of Brezhnev and the Communist Party elite. Begun in 1974, and spanning approximately 2,000 miles after twenty-nine years of construction, the BAM project was intended to showcase the national unity, determination, skill, technology, and industrial might that Soviet socialism claimed to embody. More pragmatically, the Soviet leadership envisioned the BAM railway as a trade route to the Pacific, where markets for Soviet timber and petroleum would open up, and as an engine for the development of Siberia. Despite these aspirations and the massive commitment of economic resources on its behalf, BAM proved to be a boondoggle-a symbol of late communism's dysfunctionality-and a cruel joke to many ordinary Soviet citizens. In reality, BAM was woefully bereft of quality materials and construction, and victimized by poor planning and an inferior workforce. Today, the railway is fully complete, but remains a symbol of the profligate spending and inefficiency that characterized the Brezhnev years. Christopher J. Ward provides a groundbreaking social history of the BAM railway project. He examines the recruitment of hundreds of thousands of workers from the diverse republics of the USSR and other socialist countries, and his extensive archival research and interviews with numerous project workers provide an inside look at the daily life of the BAM workforce. We see firsthand the disorganization, empty promises, dire living and working conditions, environmental damage, and acts of crime, segregation, and discrimination that constituted daily life during the project's construction. Thus, perhaps, we also see the final irony of BAM: that the most lasting legacy of this misguided effort to build Soviet socialism is to shed historical light on the profound ills afflicting a society in terminal decline.
