This book gives an account, as little biased as possible, on human space missions beyond low Earth orbit in general, and specifically to the planets of the solar system. The importance of advanced propulsion is stressed and the mathematical methods needed to design missions based on them are described. The included computer code allows the user to assess the feasibility of the various missions using different propulsion systems and how advancements in propulsion can allow humankind to become a true spacefaring civilization.

As opposite to the majority of books dealing with mission...

A half century ago, a shocking Washington Post headline claimed that the world began in five cataclysmic minutes rather than having existed for all time; a skeptical scientist dubbed the maverick theory the Big Bang. In this amazingly comprehensible history of the universe, Simon Singh decodes the mystery behind the Big Bang theory, lading us through the development of one of the most extraordinary, important, and awe-inspiring theories in science.

The Universe May Be a Mystery,
But It's No Secret

Michael Schneider leads us on a spectacular, lavishly illustrated journey along the numbers one through ten to explore the mathematical principles made visible in flowers, shells, crystals, plants, and the human body, expressed in the symbolic language of folk sayings and fairy tales, myth and religion, art and architecture. This is a new view of mathematics, not the one we learned at school but a comprehensive guide to the patterns that recur through the universe and underlie human affairs. A Beginner's...

This book provides a unified treatment of the characteristics of telescopes of all types, both those whose performance is set by geometrical aberrations and the effect of the atmosphere, and those diffraction-limited telescopes designed for observations from above the atmosphere. The emphasis throughout is on basic principles, such as Fermat's principle, and their application to optical systems specifically designed to image distant celestial sources.

The book also contains thorough discussions of the principles underlying all spectroscopic instrumentation, with special emphasis on...

Over the last two decades, the image of the U.S. space program has become seriously tarnished. Its problems have ranged from massive cost overruns to serious program delays to catastrophic mission failures. The space program, once the most prominent symbol of American scientific and technological preeminence, now seems but one more example of government bumbling, extravagance, and waste. In this study, Kay examines the recent problems of the space program and finds that NASA's failures, like its earlier successes, are ultimately traceable to the way the American political system operates....

American politicians have long been troubled by the question of whether or not to deploy a national missile defense system. The argument has focused upon the questions of cost, both political and fiscal, plus the reliability of the technologies. This study places that debate within the context of an ongoing controversy over the direction of American foreign and defense policy since the 1950s. Since that time several distinct worldviews (labeled Believers, Pragmatists, and Wilsonians) have been articulated, views which predetermine decision-makers' positions on national missile defense....

The first presentation of the novel interdisciplinary optical remote sensing technique for various ionized diluted media, based on the collisional polarization of the spectoral emission. The book provides a methodology of the impact spectropolarimetic sensing of many solutions to many practical diagnostic problems.

The adventure spans the world from Stonehenge to astronomically aligned pyramids at Giza, from Mayan observatories at Chichen Itza to the atomic clock in Washington, the world's official timekeeper since the 1960s. We visit cultures from Vedic India and Cleopatra's Egypt to Byzantium and the Elizabethan court; and meet an impressive cast of historic personages from Julius Caesar to Omar Khayyam, and giants of science from Galileo and Copernicus to Stephen Hawking. Our present calendar system predates the invention of the telescope, the mechanical clock, and the concept ol zero and its...
