Carl Sagan once noted that there is only one generation that gets to see things for the first time. We are in the midst of such a time right now, standing on the threshold of discovery in the young and remarkable field of X-ray astronomy. In The Restless Universe, astronomer Eric Schlegel offers readers an informative survey of this cutting-edge science. Two major space observatories launched in the last few years--NASA's Chandra and the European Newton--are now orbiting the Earth, sending back a gold mine of data on the X-ray universe. Schlegel, who has worked on the Chandra project for seven years, describes the building and launching of this space-based X-ray observatory. But the book goes far beyond the story of Chandra. What Schlegel provides here is the background a nonscientist would need to grasp the present and follow the future of X-ray astronomy. He looks at the relatively brief history of the field, the hardware used to detect X-rays, the satellites--past, present, and future--that have been or will be flown to collect the data, the way astronomers interpret this data, and, perhaps most important, the insights we have already learned as well as speculations about what we may soon discover. And throughout the book, Schlegel conveys the excitement of looking at the universe from the perspective brought by these new observatories and the sharper view they deliver. Drawing on observations obtained from Chandra, Newton, and previous X-ray observatories, The Restless Universe gives a first look at an exciting field which significantly enriches our understanding of the universe.

Highly readable introduction to modern physics, written by a Nobel laureate, develops general concepts of Newtonian mechanics and thermodynamics. Additional topics include the structure of the atom and nuclear physics.

A heavily-illustrated guide to the concepts and application of modern physics, particularly in the areas concerning molecular and atomic reactions

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

A core principle of modern science holds that a scientific explanation must not attribute will or agency to natural phenomena. "The Restless Clock" examines the origins and history of this, in particular as it applies to the science of living things. This is also the story of a tradition of radicals--dissenters who embraced the opposite view, that agency is an essential and ineradicable part of nature. Beginning with the church and courtly automata of early modern Europe, Jessica Riskin guides us through our thinking about the extent to which animals might be understood as mere machines. We encounter fantastic robots and cyborgs as well as a cast of scientific and philosophical luminaries, including Descartes and Leibnitz, Lamarck and Darwin, whose ideas gain new relevance in Riskin's hands. The book ends with a riveting discussion of how the dialectic continues in genetics, epigenetics, and evolutionary biology, where work continues to naturalize different forms of agency. "The Restless Clock "reveals the deeply buried roots of current debates in artificial intelligence, cognitive science, and evolutionary biology.

From the savanna to the city to outer space, celebrated Nordic children's book illustrator Linda Bondestam offers a charming peek at the many ways we settle in for sleep, with gorgeous, dreamlike illustrations full of offbeat humor. Discover the bedtime routines of animals all over the world through the eyes of an alien family on a faraway planet. Little monkey needs his mama to play at least seventy-three songs on the ukulele to fall asleep. A meerkat family enjoys some stretches together as the sun goes down, while baby sloth is a bedtime expert--she's already snoozing soundly in the trees. Die-cut pages invite little ones to help new animal friends get cozy under the covers. With unconventional illustrations full of wit and tenderness, Good Night Earth is a sweetly silly exploration of how all kinds of creatures find peaceful and playful ways to end the day.
