'I Did It' Mathematics 4 Primary
'I Did It' Mathematics, an activity-based and interactive course, has been prepared in conformity with the latest NCERT syllabus and the National Curriculum Framework (2005). It presents mathematical concepts in a logical and comprehensive manner and with high degree of clarity. It also encourages students to think, discuss and assimilate ideas and concepts with great ease. The simple and lucid manner of presentation of contents coupled with large number of illustrative examples facilitate easy grasp of concepts. The in-text activities in the books provide opportunity to students to relate mathematical concepts with everyday life. Key Features - Well-graded and thematically organised units - Topics and activities linked to learner's everyday life - Large number of questions in the exercises, including word problems - Overview to help teachers develop comprehensive lesson plans - Maths Lab Activities to reinforce the concepts learnt in each chapter
Who Owns Outer Space?
Explores the environmental, safety, and security challenges facing humanity's rapid expansion into Space and proposes actionable solutions.
Impact of Modern Dynamics in Astronomy
Modem dynamics is increasingly participating in the solution of problems raised by as tronomical observations. This new relationship is being fostered on one side by the im provements in the observations, which in recent years contributed several discoveries of new systems, such as the objects in the Kuiper belt, the pulsar and star companions, to speak only of the most striking ones, and, on the other hand, by the progresses in modem dynamics. The progresses in modem dynamics are due to two factors: the dissemination of fast computers, allowing the numerical studies of very complex systems by a large number of scientists, and the improvement in our understanding of the complex behaviour of Hamiltonian systems. KAM and Nekhorochev theories have shed a light on the subtle and surprizing interplays between regular and chaotic motions; numerical experiments and analytical approximations have shown how these peculiarities are indeed present in astronomically important systems and are instrumental in understanding their formation and evolution.
The Restless Universe Applications of Gravitational N-Body Dynamics to Planetary Stellar and Galactic Systems
The Restless Universe: Applications of Gravitational N-Body Dynamics to Planetary Stellar and Galactic Systems stimulates the cross-fertilization of ideas, methods, and applications among the different communities who work in the gravitational N-body problem arena, across diverse fields of astrophysics. The chapters and topics cover three broad the
Civic Astronomy
The founding of the Dudley Observatory at Albany, N.Y., in 1852 was a milestone in humanity's age-old quest to understand the heavens. As the best equipped astronomical observatory in the U.S. led by the first American to hold a Ph.D. in astronomy, Benjamin Apthorp Gould Jr., the observatory helped pioneer world-class astronomy in America. It also proclaimed Albany's status as a major national center of culture, knowledge and affluence. This book explores the story of the Dudley Observatory as a 150 year long episode in civic astronomy. The story ranges from a bitter civic controversy to a venture into space, from the banks of the Hudson River to the highlands of Argentina. It is a unique glimpse at a path not taken, a way of doing science once promising, now vanished. As discoveries by the Dudley Observatory's astronomers, especially its second director Lewis Boss, made significant contributions to the modern vision of our Milky Way galaxy as a rotating spiral of more than a million stars, the advance of astronomy left that little observatory behind.

Cores to Clusters
It was with pleasure that CAUP became for three days the core to the cloud of star formation experts all over the world. Close to the celebration of its 15th anniversary – therefore still in the early stages of institutional evolution – we are proud of our multiple activities in Astronomy: a productive research centre, classi?ed as “Institution of excellence” within the Portuguese research units, but also an “Institution of Public Utility” as recognised by the Government. Fifteen years ago we choose to play a role not only in research, as expected from any research centre but also in the training of the future astronomers and the promotion of science and scienti?c culture. This c...
Starbursts
Starbursts are important features of early galaxy evolution. Many of the distant, high-redshift galaxies we are able to detect are in a starbursting phase, often apparently provoked by a violent gravitational interaction with another galaxy. In fact, if we did not know that major starbursts existed, these conference proceedings testify that we would indeed have difficulties explaining the key properties of the Universe! These conference proceedings cover starbursts from the small-scale star-forming regions in nearby galaxies to galaxy-wide events at high redshifts; one of the major themes of the conference proved to be "scalability", i.e., can we scale up the small-scale events to describe the physics on larger scales. The key outcome of this meeting – and these proceedings – is a resounding "yes" to this fundamental, yet profound question. The enhanced synergy facilitated by the collaboration among observers using cutting-edge ground and space-based facilities, theorists and modellers has made these proceedings a true reflection of the state of the art in this very rapidly evolving field.
Near-Earth Objects
An insider's look at the science of near-Earth comets and asteroids Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects—its history, applications, and ongoing quest to find near-Earth objects before they find us. In its course around the sun, the Earth passes through a veritable shooting gallery of millions of nearby comets and asteroids. One suc...
The Atlas of AI
The hidden costs of artificial intelligence, from natural resources and labor to privacy and freedom What happens when artificial intelligence saturates political life and depletes the planet? How is AI shaping our understanding of ourselves and our societies? In this book Kate Crawford reveals how this planetary network is fueling a shift toward undemocratic governance and increased inequality. Drawing on more than a decade of research, award-winning science, and technology, Crawford reveals how AI is a technology of extraction: from the energy and minerals needed to build and sustain its infrastructure, to the exploited workers behind “automated” services, to the data AI collects from us. Rather than taking a narrow focus on code and algorithms, Crawford offers us a political and a material perspective on what it takes to make artificial intelligence and where it goes wrong. While technical systems present a veneer of objectivity, they are always systems of power. This is an urgent account of what is at stake as technology companies use artificial intelligence to reshape the world.
