Epic rivalry

Inside the soviet and american space race
When Neil Armstrong and Buzz Aldrin walked on the moon in 1969, they personified an almost unimaginable feat--the incredibly complex task of sending humans safely to another celestial body. This extraordinary odyssey, which grew from the rivalry between the United States and the Soviet Union during the Cold War, was galvanized by the Sputnik launch in 1957. To mark the fiftieth anniversary of Sputnik, National Geographic recaptures this gripping moment in the human experience with a lively and compelling new account. Written by Smithsonian curator Von Hardesty and researcher Gene Eisman, Epic Rivalry tells the story from both the American and the Russian points of view, and shows how each space-faring nation played a vital role in stimulating the work of the other. Scores of rare, unpublished, and powerful photographs recall the urgency and technical creativity of both nations' efforts. The authors recreate in vivid detail the "parallel universes" of the two space exploration programs, with visionaries Wernher von Braun and Sergei Korolev and political leaders John F. Kennedy and Nikita Khrushchev at the epicenters. The conflict between countries, and the tense drama of their independent progress, unfolds in vivid prose. Approaching its subject from a uniquely balanced perspective, this important new narrative chronicles the epic race to the moon and back as it has never been told before--and captures the interest of casual browsers and science, space, and history enthusiasts alike.

Women scientists

Reflections, challenges, and breaking boundaries
Magdolna Hargittai uses over fifteen years of in-depth conversation with female physicists, chemists, biomedical researchers, and other scientists to form cohesive ideas on the state of the modern female scientist. The compilation, based on sixty conversations, examines unique challenges that women with serious scientific aspirations face. In addition to addressing challenges and the unjustifiable underrepresentation of women at the higher levels of academia, Hargittai takes a balanced approach by discussing how some of the most successful of these women have managed to obtain professional success and personal happiness. Women Scientists portrays scientists from different backgrounds, different geographical regions-eighteen countries from four continents-and leaders from a variety of professional backgrounds, including eight Nobel laureate women. The book is divided into three sections: "Husband and Wife Teams," "Women at the Top," and "In High Positions." Hargittai uses her own experience to introduce her first section on the lives of prominent scientific couples and addresses the joys and disadvantages of husband and wife teams. The second section is a comprehensive exploration of the struggles and triumphs of "women at the top." Hargittai introduces women from countries where relatively little has been written about female scientists. The final section focuses on women scientists involved with science administration and leadership. Hargittai's biographical sketches role models for budding scientists. The book is a much needed account of female presence and influence in the sciences.
