Download or read book With Stars in Their Eyes written by James B. Breckinridge and published by Oxford University Press. This book was released on 2022-02-04 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book details the lives of two married geniuses, Aden and Marjorie Meinel, who helped to pioneer modern optics and solar energy in the U.S. Aden B. Meinel and Marjorie P. Meinel stood at the confluence of several overarching technological developments during their lifetimes, including postwar aerial surveillance by spy planes and satellites, solar energy, the evolution of telescope design, interdisciplinary optics, and photonics. Yet, their incredible stories and their long list of scientific contributions have never been adequately recognized in one place. In this book, James Breckinridge and Alec M. Pridgeon correct this oversight by sharing the story of this powerful duo. The book follows their lives and covers large scientific developments between World War II to the Cold War. James B. Breckinridge, a previous advisee and later colleague to the Meinels, and historian and scientist Alec M. Pridgeon collected more than 200 hours of oral interviews with those who worked closely with the Meinels and some who built their careers around the findings made possible by their work. The book shares and analyzes the work done by the Meinels, and it also includes incredible insights from an unpublished Meinel autobiography.

Download or read book Gas Lasers written by Masamori Endo and published by CRC Press. This book was released on 2018-10-03 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lasers with a gaseous active medium offer high flexibility, wide tunability, and advantages in cost, beam quality, and power scalability. Gas lasers have tended to become overshadowed by the recent popularity and proliferation of semiconductor lasers. As a result of this shift in focus, details on modern developments in gas lasers are difficult to find. In addition, different types of gas lasers have unique properties that are not well-described in other references. Collecting expert contributions from authorities dealing with specific types of lasers, Gas Lasers examines the fundamentals, current research, and applications of this important class of laser. It is important to understand all types of lasers, from solid-state to gaseous, before making a decision for any application. This book fills in the gaps by discussing the definition and properties of gaseous media along with its fluid dynamics, electric excitation circuits, and optical resonators. From this foundation, the discussion launches into the basic physics, characteristics, applications, and current research efforts for specific types of gas lasers: CO lasers, CO2 lasers, HF/DF lasers, excimer lasers, iodine lasers, and metal vapor lasers. The final chapter discusses miscellaneous lasers not covered in the previous chapters. Collecting hard-to-find material into a single, convenient source, Gas Lasers offers an encyclopedic survey that helps you approach new applications with a more complete inventory of laser options.

Download or read book Solar and Space Physics written by National Research Council and published by National Academies Press. This book was released on 2013-09-26 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outward to a region far beyond Pluto where the Sun's influence wanes, advances during the past decade in space physics and solar physics-the disciplines NASA refers to as heliophysics-have yielded spectacular insights into the phenomena that affect our home in space. Solar and Space Physics, from the National Research Council's (NRC's) Committee for a Decadal Strategy in Solar and Space Physics, is the second NRC decadal survey in heliophysics. Building on the research accomplishments realized during the past decade, the report presents a program of basic and applied research for the period 2013-2022 that will improve scientific understanding of the mechanisms that drive the Sun's activity and the fundamental physical processes underlying near-Earth plasma dynamics, determine the physical interactions of Earth's atmospheric layers in the context of the connected Sun-Earth system, and enhance greatly the capability to provide realistic and specific forecasts of Earth's space environment that will better serve the needs of society. Although the recommended program is directed primarily at NASA and the National Science Foundation for action, the report also recommends actions by other federal agencies, especially the parts of the National Oceanic and Atmospheric Administration charged with the day-to-day (operational) forecast of space weather. In addition to the recommendations included in this summary, related recommendations are presented in this report.

Download or read book The Environmental Element in Space Law written by Lotta Viikari and published by BRILL. This book was released on 2008-06-30 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: While decades of space ventures have led to significant technological advances, space activities have also brought increasing environmental problems. This book examines the current international legal regimes in space law and environmental law in order to ascertain their applicability and efficacy in addressing environmental threats in the space sector. The research suggests mechanisms which could improve environmental protection in the sector and strengthen the environmental element in space law. These mechanisms include a variety of norm-setting strategies used in international environmental management. Special attention is drawn to the potential of environmental impact assessment in the space sector and to dispute resolution procedures. Like other areas of human activities, the space sector should accommodate both economic interests and environmental protection in line with the principle of sustainable development

Available in PDF, EPUB and Kindle. Book excerpt: As civil space policies and programs have evolved, the geopolitical environment has changed dramatically. Although the U.S. space program was originally driven in large part by competition with the Soviet Union, the nation now finds itself in a post-Cold War world in which many nations have established, or are aspiring to develop, independent space capabilities. Furthermore discoveries from developments in the first 50 years of the space age have led to an explosion of scientific and engineering knowledge and practical applications of space technology. The private sector has also been developing, fielding, and expanding the commercial use of space-based technology and systems. Recognizing the new national and international context for space activities, America's Future in Space is meant to advise the nation on key goals and critical issues in 21st century U.S. civil space policy.

Download or read book The Cosmos on a Shoestring written by Liam Sarsfield and published by RAND Corporation. This book was released on 1998 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small spacecraft have become popular for a number of reasons, most prominently the needs to reduce overall cost, be built more quickly, and spread mission risks. NASA has been challenged with crafting a program that continues to produce meaningful science within the constraints of the available budget. Still, pound for pound, small spacecraft are not precisely inexpensive, given the effects of complexity, launch costs, and a greater degree of risk. Historically, science spacecraft have demonstrated increasing reliability, but this trend might not continue, given the shift to managed risk. There is generally less money available to smaller programs to test spacecraft functions and operational procedures prior to launch. Small spacecraft are also generally less robust. Efforts to reduce failure potentials through the application of more reliable components, better testing, and advanced design techniques should receive greater attention. Despite the risks, however, small spacecraft fulfill important roles in earth science, astrophysics, space physics, and planetary science. NASA's current generation of small spacecraft is capable of impressive levels of performance.

This book was released on 2020-01-09 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have done a masterful job of charting the important story of DARPA, one of the key catalysts of technological innovation in US recent history. By plotting the development, achievements and structure of the leading world agency of this kind, this book stimulates new thinking in the field of technological innovation with bearing on how to respond to climate change, pandemics, cyber security and other global problems of our time. The DARPA Model provides a useful guide for governmental agency and policy leaders, and for anybody interested in the role of governments in technological innovation. —Dr. Kent Hughes, Woodrow Wilson International Center for Scholars This volume contains a remarkable collection of extremely insightful articles on the world’s most successful advanced technology agency. Drafted by the leading US experts on DARPA, it provides a variety of perspectives that in turn benefit from being presented together in a comprehensive volume. It reviews DARPA’s unique role in the U.S. innovation system, as well as the challenges DARPA and its clones face today. As the American model is being considered for adoption by a number of countries worldwide, this book makes a welcome and timely contribution to the policy dialogue on the role played by governments in stimulating technological innovation. — Prof. Charles Wessner, Georgetown University The U.S. Defense Advanced Research Projects Agency (DARPA) has played a remarkable role in the creation new transformative technologies, revolutionizing defense with drones and precision-guided munitions, and transforming civilian life with portable GPS receivers, voice-recognition software, self-driving cars, unmanned aerial vehicles, and, most famously, the ARPANET and its successor, the Internet. Other parts of the U.S. Government and some foreign governments have tried to apply the ‘DARPA model’ to help develop valuable new technologies. But how and why has DARPA succeeded? Which features of its operation and environment contribute to this success? And what lessons does its experience offer for other U.S. agencies and other governments that want to develop and demonstrate their own ‘transformative technologies’? This book is a remarkable collection of leading academic research on DARPA from a wide range of perspectives, combining to chart an important story from the Agency’s founding in the wake of Sputnik, to the current attempts to adapt it to use by other federal agencies. Informative and insightful, this guide is essential reading for political and policy leaders, as well as researchers and students interested in understanding the success of this agency and the lessons it offers to others.
