Book Description
It is well known that the biochemical processes of life on Earth are maintained by the external solar radiation and can be reduced to the synthesis and decomposition of organic matter. Man has added the synthesis and decomposition of various in dustrial products to these natural processes. On one hand, biological synthesis may only be conducted within the rather narrow margins of parameters of the environ ment, including temperature, humidity, concentrations of the inorganic substances used by life (such as carbon dioxide, oxygen, etc.) On the other hand, the physical and chemical composition of the environment suffers significant changes during those processes of synthesis and decomposition. The maximum possible rate of such change due to the activity of living beings can exceed the average geophysical rates of change of the environment due to activity ofterrestrial depths and cosmic processes by a factor often thousand. In the absence of a rigid correlation between the biological synthesis and decomposition, the environment would be greatly disturbed within a decade and driven into a state unfit for life. A lifeless Earth, however would suffer similar changes only after about a hundred thousand years. Preservation of the existing state of the environment is only possible with strict equality between the rates of biological synthesis and decomposition, that is, when the biochemical cycles of matter are virtually closed.

Book Description
Traditionally, the natural sciences have been divided into two branches: the biological sciences and the physical sciences. Today, an increasing number of scientists are addressing problems lying at the intersection of the two. These problems are most often biological in nature, but examining them through the lens of the physical sciences can yield exciting results and opportunities. For example, one area producing effective cross-discipline research opportunities centers on the dynamics of systems. Equilibrium, multistability, and stochastic behavior-concepts familiar to physicists and chemists-are now being used to tackle issues associated with living systems such as adaptation, feedback, and emergent behavior. Research at the Intersection of the Physical and Life Sciences discusses how some of the most important scientific and societal challenges can be addressed, at least in part, by collaborative research that lies at the intersection of traditional disciplines, including biology, chemistry, and physics. This book describes how some of the mysteries of the biological world are being addressed using tools and techniques developed in the physical sciences, and identifies five areas of potentially transformative research. Work in these areas would have significant impact in both research and society at large by expanding our understanding of the physical world and by revealing new opportunities for advancing public health, technology, and stewardship of the environment. This book recommends several ways to accelerate such cross-discipline research. Many of these recommendations are directed toward those administering the faculties and resources of our great research institutions-and the stewards of our research funders, making this book an excellent resource for academic and research institutions, scientists, universities, and federal and private funding agencies.

Book Description
Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.

Book Description
Dialogue on global warming has progressed from the Kyoto Protocol to meetings in Copenhagen and Cancun and will soon resume in meetings in South Africa. Some observers consider the Copenhagen conference a failure. EU representatives, in contrast, present an optimistic evaluation of achieving a global temperature rise limit of not more than 2°C by 2100. Geoscience researchers and lead investigators of the Intergovernmental Panel on Climate Change (IPCC) have supported CO2 emission reduction pledges and contend that we can achieve the 2°C limit through international coordination. This position conflicts with evaluations of United States Congressional and Presidential advisors, who do not believe the Copenhagen CO2 reduction commitments can hold the global warming increase to below 2°C and who have not supported the agreement. Developing countries are alarmed, because climate change is expected to hit them hardest. The developed world will use energy to mitigate global warming effects, but developing countries are more exposed by geography and poverty to the most dangerous consequences of a global temperature rise. The Oxford Handbook of the Macroeconomics of Global Warming analyzes the macroeconomics of global warming, especially the economics of possible preventative measures, various policy changes, and potential effects of climate change on developing and developed nations.

Book Description
This book argues that the Soviet Union was a highly influential actor in furthering understandings of society-nature interaction on the international stage and played a key role in helping to shape, conceptualize and assess the relationship between humankind and the Earth system. It considers how humankind’s capacity to affect physical and biological systems at a global scale was acknowledged and studied by Soviet scientists, discusses how the interaction between Soviet and Western scientists stimulated the development of new technologies and insights, which simultaneously facilitated a more profound understanding of the Earth’s physical and biological systems, and explores how Soviet scientists drew upon pre-revolutionary intellectual traditions in order to make sense of society-nature interaction and did so in collaboration with a range of international initiatives. Overall, the book provides a deep analysis of how Soviet scientists conceptualized society-nature interaction and influenced the understanding of global physical and biological systems. Furthermore, it is argued that this intellectual legacy remains of importance today with respect to the activities of Russian science and contemporary global environmental challenges.

Book Description
This book discusses the journey of Dr. K Kasturirangan, who shares his experience during his long tenure at ISRO including the Chairmanship of ISRO, subsequently membership of the Rajya Sabha, the Planning Commission and many other responsibilities. Over the past five decades of public and professional service to the nation, Dr. Kasturirangan has graduated from a young researcher in astrophysics working under Vikram Sarabhai to leading India’s space program (ISRO), being entrusted by five successive Prime Ministers, besides dealing with several other domains of responsibilities beyond space, all of which have significantly impacted India’s development. This book centers around select 12 public invited lectures, Dr. Kasturirangan delivered ranging from developing hi-tech space systems, to managing an organization as intricate as ISRO which was guided by the wisdom of mentors, including Vikram Sarabhai, M G K Menon, Satish Dhawan and U. R. Rao, to tackling multi-faceted socio-economic issues, including India’s nuclear deal, report headed by him on the Western Ghats ecosystem, and the new National Education Policy 2020. Scientists, historians, policy makers, management strategists, journalists, or anyone with a keen interest in understanding the processes behind such large-scale science, technology and socio-economic endeavors – right from planning, creating appropriate institutional mechanisms, working with multiple stakeholders to ensure that these programs deliver tangible benefits to society, articulating these benefits with clarity to political leaders to assure public support – will find this book deeply instructive and illuminating. It will be of interest to the scientific, education and management community as well as to policy makers and researchers affiliated with multifaceted developmental issues.
