Exploring Space (Discovery and Exploration) Book

EBook Description: Chelsea House Publications | English | 2009-12-30 | ISBN: 1604131888 | 119 pages | PDF | 23 MB Throughout history, people have tried to understand Earth's place in the universe and what else, if anything, is 'out there'. This common human curiosity has led to great discoveries, from astrologers in ancient Babylon and Egypt who sought to link the strange planetary paths through the night sky to human behavior, to the 17th century when Galileo turned his first telescope on the night sky, to the 21st century when robotic explorers landed on Mars. "Exploring Space, Revised Edition" offers extensive coverage of human explorations into space - from 19th-century fantasy to 20th-century achievement and the future of space exploration in the 21st century - giving up-to-date information about the current state of exploration in the final frontier. Coverage of this title includes: native American astronomy; the U.S.-Soviet 'race to the moon' in the 1960s; how astronomers began to realize that Earth was only one of several planets; the challenges NASA has faced, such as the explosions of the Challenger and the Columbia Development of space stations; and, an examination of the future of space exploration.

A fascinating exploration of the science of the impossible--from death rays and force fields to invisibility cloaks--revealing to what extent such technologies might be achievable decades or millennia into the future.

One hundred years ago, scientists would have said that lasers, televisions, and the atomic bomb were beyond the realm of physical possibility. In Physics of the Impossible, the renowned physicist Michio Kaku explores to what extent the technologies and devices of science fiction that are deemed equally impossible today might well become commonplace in the future.

From teleportation to telekinesis, Kaku uses the world of science fiction to explore the fundamentals--and the limits--of the laws of physics as we know them today. He ranks the impossible technologies by categories--Class I, II, and III, depending on when they might be achieved, within the next century, millennia, or perhaps never. In a compelling and thought-provoking narrative, he explains:

How the science of optics and electromagnetism may one day enable us to bend light around an object, like a stream flowing around a boulder, making the object invisible to observers "downstream"
How ramjet rockets, laser sails, antimatter engines, and nanorockets may one day take us to the nearby stars
How telepathy and psychokinesis, once considered pseudoscience, may one day be possible using advances in MRI, computers, superconductivity, and nanotechnology
Why a time machine is apparently consistent with the known laws of quantum physics, although it would take an unbelievably advanced civilization to actually build one

Kaku uses his discussion of each technology as a jumping-off point to explain the science behind it. An extraordinary scientific
adventure, Physics of the Impossible takes readers on an unforgettable, mesmerizing journey into the world of science that both enlightens and entertains.

"Explorations in Mathematical Physics

Have you ever wondered why the language of modern physics centres on geometry? Or how quantum operators and Dirac brackets work? What a convolution really is? What tensors are all about? Or what field theory and lagrangians are, and why gravity is described as curvature?
This book takes you on a tour of the main ideas forming the language of modern mathematical physics. Here you will meet novel approaches to concepts such as determinants and geometry, wave function evolution, statistics, signal processing, and three-dimensional rotations. You'll see how the accelerated frames of special relativity tell us about gravity. On the journey, you'll discover how tensor notation relates to vector calculus, how differential geometry is built on intuitive concepts, and how variational calculus leads to field theory. You will meet quantum measurement theory, along with Green functions and the art of complex integration, and finally general relativity and cosmology.

The book takes a fresh approach to tensor analysis built solely on the metric and vectors, with no need for one-forms. This gives a much more geometrical and intuitive insight into vector and tensor calculus, together with general relativity, than do traditional, more abstract methods.
