At the outbreak of World War II, four scientists left their comfortable college teaching positions to work for the government. Three served in uniform, the fourth oversaw contracts for the Navy. Such dramatic changes in life styles during the period were common -- for men. But these established scientists were women, and each made significant contributions to a Navy embroiled in a modern, science-dependent war. Mary Sears, a Woods Hole Oceanographic Institution planktonologist, headed the Hydrographic Office's Oceanographic Unit. Grace Hopper, a Yale-trained mathematician, went to the Bureau of Ships Computation Laboratory at Harvard where she worked on one of the first computers, churning out essential data for ordnance and other projects. Florence van Straten, a New York University chemist, served as an aerological engineer analyzing the use of weather in combat. Mina Rees was the chief technical aide to the applied mathematics panel of the National Defense Research Committee. This book firmly places the women within the context of their times. Deeply rooted in previously unexamined primary sources, the work helps readers understand the personal and professional experiences of women in the military and the attitudes they faced, and fully appreciate the educational and occupational barriers faced by women scientists in the 1930s and 1940s. The author focuses on their efforts during the war, but also discusses the women's skills and training, tells how they came to war work, and examines the contributions they made once there. She further considers how the war changed their lives, especially their professional lives, and how it affected their future careers. While other books havebeen written about women in the military, this is the first to focus on Navy women scientists.

Mathematics has for centuries been stimulated, financed and credited by military purposes. Some mathematical thoughts and mathematical technology have also been vital in war. During World War II mathematical work by the Anti-Hitler coalition was part of an aspiration to serve humanity and not help destroy it. At present, it is not an easy task to view the bellicose potentials of mathematics in a proper perspective. The book presents historical evidence and recent changes in the interaction between mathematics and the military. It discusses the new mathematically enhanced development of military technology which seems to have changed the very character of modern warfare.

From rocket scientists to code breakers, “fascinating stories” of women who overcame obstacles, shattered stereotypes, and pursued their passion for math (Notices of the American Mathematical Society). With more than 200 photos and original interviews with several of the amazing women covered, Power in Numbers: The Rebel Women of Mathematics is a full-color volume that puts a spotlight on the influence of women on the development of mathematics over the last two millennia. Each biography reveals the life of a different female mathematician, from her childhood and early influences to the challenges she faced and the great achievements she made in spite of them.

When Grace Hopper retired as a rear admiral from the U.S. Navy in 1986, she was the first woman restricted line officer to reach flag rank and, at the age of seventy-nine, the oldest serving officer in the Navy. A mathematician by training who became a computer scientist, the eccentric and outspoken Hopper helped propel the Navy into the computer age. She also was a superb publicist for the Navy, appearing frequently on radio and television and quoted regularly in newspapers and magazines. Yet in spite of all the attention she received, until now ""Amazing Grace,"" as she was called, has never been the subject of a full biography. Kathleen Broome Williams looks at Hopper's entire naval career, from the time she joined the WAVES and was sent in 1943 to work on the Mark I computer at Harvard, where she became one of the country's first computer programmers. Thanks to this early Navy introduction to computing, the author explains, Hopper had a distinguished civilian career in commercial computing after the war, gaining fame for her part in the creation of COBOL. The admiral's Navy days were far from over, however, and Williams tells how Hopper--already past retirement age--was recalled to active duty at the Pentagon in 1967 to standardize computer-programming languages for Navy computers. Her temporary appointment lasted for nineteen years while she standardized COBOL for the entire department of defense. Based on extensive interviews with colleagues and family and on archival material never before examined, this biography not only illuminates Hopper's pioneering accomplishments in a field that came to be dominated by men, but provides a fascinating overview of computing from its beginnings in World War II to the late 1980s.

The fascinating untold story of digital cash and its creators—from experiments in the 1970s to the mania over Bitcoin and other cryptocurrencies Bitcoin may appear to be a revolutionary form of digital cash without precedent or prehistory. In fact, it is only the best-known recent experiment in a long line of similar efforts going back to the 1970s. But the story behind cryptocurrencies like Bitcoin and its blockchain technology has largely been untold—until now. In Digital Cash, Finn Brunton reveals how technological utopians and political radicals created experimental money to bring about their visions of the future: to protect privacy, bring down governments, prepare for apocalypse, or launch a civilization of innovation and abundance that would make its creators immortal. Filled with marvelous characters, stories, and ideas, Digital Cash is an engaging and accessible account of the strange origins and remarkable technologies behind today's cryptocurrency explosion.

“[An] amiable, in-depth examination of the most critical era for the development of modern oceanography” (Publishers Weekly). In a history at once scientific and cultural, Helen Rozwadowski shows us how the Western imagination awoke to the ocean's possibilities?in maritime novels, in the popular hobby of marine biology, in the youthful sport of yachting, and in the laying of a trans-Atlantic telegraph cable. The ocean emerged as important new territory, and scientific interests intersected with those of merchant-industrialists and politicians. Rozwadowski documents the popular crazes that coincided with these interests?from children's sailor suits to the home aquarium and the surge in ocean travel. She describes how, beginning in the 1860s, oceanography moved from yachts onto the decks of oceangoing vessels, and landlubber naturalists found themselves navigating the routines of a working ship's physical and social structures. Fathoming the Ocean offers a rare and engaging look into our fascination with the deep sea and into the origins of oceanography?origins still visible in a science that focuses the efforts of physicists, chemists, geologists, biologists, and engineers on the common enterprise of understanding a vast, three-dimensional, alien space. “Rozwadowski greatly expands our own understanding, all while telling a story that is original, wide-ranging, and illuminating.” —Margaret Deacon, Southampton Oceanography Centre, author of Science and the Sea: The Origins of Oceanography “Required reading for anyone wanting to understand how the oceans have come to play the role that they do in Western knowledge.” —Eric L. Mills, Dalhousie University and author of Biological Oceanography: An Early History, 1870-1960 “Chronicles the birth of deep-sea oceanography, from early observations by Benjamin Franklin to the voyage of HMS Challenger in the 1870s. [Rozwadowski] weaves a rich narrative from the world of renowned as well as lesser-known oceanographers.” —Nature
