Space-based observations have transformed our understanding of Earth, its environment, the solar system and the universe at large. During past decades, driven by increasingly advanced science questions, space observatories have become more sophisticated and more complex, with costs often growing to billions of dollars. Although these kinds of ever-more-sophisticated missions will continue into the future, small satellites, ranging in mass between 500 kg to 0.1 kg, are gaining momentum as an additional means to address targeted science questions in a rapid, and possibly more affordable, manner. Within the category of small satellites, CubeSats have emerged as a space-platform defined in terms of (10 cm x 10 cm x 10 cm)- sized cubic units of approximately 1.3 kg each called "U's." Historically, CubeSats were developed as training projects to expose students to the challenges of real-world engineering practices and system design. Yet, their use has rapidly spread within academia, industry, and government agencies both nationally and internationally. In particular, CubeSats have caught the attention of parts of the U.S. space science community, which sees this platform, despite its inherent constraints, as a way to affordably access space and perform unique measurements of scientific value. The first science results from such CubeSats have only recently become available; however, questions remain regarding the scientific potential and technological promise of CubeSats in the future. Achieving Science with CubeSats reviews the current state of the scientific potential and technological promise of CubeSats. This report focuses on the platform's promise to obtain high- priority science data, as defined in recent decadal surveys in astronomy and astrophysics, Earth science and applications from space, planetary science, and solar and space physics (heliophysics); the science priorities identified in the 2014 NASA Science Plan; and the potential for CubeSats to advance biology and microgravity research. It provides a list of sample science goals for CubeSats, many of which address targeted science, often in coordination with other spacecraft, or use "sacrificial," or high-risk, orbits that lead to the demise of the satellite after critical data have been collected. Other goals relate to the use of CubeSats as constellations or swarms deploying tens to hundreds of CubeSats that function as one distributed array of measurements.

Kirchhoff’s laws give a mathematical description of electromechanics. Similarly, translational motion mechanics obey Newton’s laws, while rotational motion mechanics comply with Euler’s moment equations, a set of three nonlinear, coupled differential equations. Nonlinearities complicate the mathematical treatment of the seemingly simple action of rotating, and these complications lead to a robust lineage of research culminating here with a text on the ability to make rigid bodies in rotation become self-aware, and even learn. This book is meant for basic scientifically inclined readers commencing with a first chapter on the basics of stochastic artificial intelligence to bridge readers to very advanced topics of deterministic artificial intelligence, espoused in the book with applications to both electromechanics (e.g. the forced van der Pol equation) and also motion mechanics (i.e. Euler’s moment equations). The reader will learn how to bestow self-awareness and express optimal learning methods for the self-aware object (e.g. robot) that require no tuning and no interaction with humans for autonomous operation. The topics learned from reading this text will prepare students and faculty to investigate interesting problems of mechanics. It is the fondest hope of the editor and authors that readers enjoy the book.

In this previously unpublished manuscript, found in the Rothbard Archives, Rothbard deftly turns the tables on the supporters of big government and their mandate for control of research and development in all areas of the hard sciences. What R&D should be encouraged and funded, what inventions should be supported, and what areas should be given research grants, etc.? These decisions can only be decided by markets unburdened by government meddling and intervention. Rothbard shows that science best advances under the free market: the claims to the contrary of the centralizers are spurious. The best course of action for government is to get out of the way ...

Knowledge matters, and states have a stake in managing its movement to protect a variety of local and national interests. The view that knowledge circulates by itself in a flat world, unimpeded by national boundaries, is a myth. The transnational movement of knowledge is a social accomplishment, requiring negotiation, accommodation, and adaptation to the specificities of local contexts. This volume of essays by historians of science and technology breaks the national framework in which histories are often written. Instead, How Knowledge Moves takes knowledge as its central object, with the goal of unraveling the relationships among people, ideas, and things that arise when they cross national borders. This specialized knowledge is located at multiple sites and moves across borders via a dazzling array of channels, embedded in heads and hands, in artifacts, and in texts. In the United States, it shapes policies for visas, export controls, and nuclear weapons proliferation; in Algeria, it enhances the production of oranges by colonial settlers; in Vietnam, it facilitates the exploitation of a river delta. In India it transforms modes of agricultural production. It implants American values in Latin America. By concentrating on the conditions that allow for knowledge movement, these essays explore travel and exchange in face-to-face encounters and show how border-crossings mobilize extensive bureaucratic technologies.

An incisive and powerful investigation of corporate impact on human and planetary well-being Freedom of choice lies at the heart of American society. Every day, individuals decide what to eat, which doctors to see, who to connect with online, and where to educate their children. Yet, many Americans don't realize that these choices are illusory at best. By the start of the 21st century, every major industrial sector in the global economy was controlled by no more than five transnational corporations, and in about a third of these sectors, a single company accounted for more than 40 percent of global sales. The available options in food, healthcare, education, transportation, and even online presence are largely constructed by corporations, whose sweeping influence have made them the public face and executive agents of 21st-century capitalism. At What Cost confronts how globalization, financial speculation, monopolies, and control of science and technology have enhanced the ability of corporations and their allies to overwhelm influences of government, family, community, and faith. As corporations manipulate demand through skillful marketing and veto the choices that undermine their bottom line, free consumer choice has all but disappeared, and with it, the personal protections guarding our collective health. At What Cost argues that the world created by 21st-century capitalism is simply not fit to solve our most serious public health problems, from climate change to opioid addiction. However, author and public health expert Nicholas Freudenberg also shows that though the road is steep, human and planetary well-being constitute a powerful mobilizing idea for a new social movement, one that will restore the power of individual voice to our democracy. With impeccably detailed research and an eye towards a better future, At What Cost arms ordinary citizens, activists, and health professionals with an understanding of how we've arrived at the precipice, and what we can do to ensure a healthier collective future.
