Theory Of Interplanetary Flights

RRP $257.99

Click on the Google Preview image above to read some pages of this book!

This unique monograph contains a comprehensive overview of celestial mechanics, providing the reader with a solid basis on which to build an understanding of the theory of interplanetary flights. The theoretical development is illustrated with a number of practical examples, bringing to bear the author's wealth of experience gained from working of the Soviet space programme. Many examples are taken from current space topics, including the Shoemaker-Levy 9 comet, the flight of Ulysses over the Solar poles, and the Voyagers' tour of the Solar system. Recent theoretical achivements, such as the intriguing problem of chaos in the Solar system, are also covered.
This book will appeal to students and researchers interested in both the theoretical and applied aspects of the topic. The clarity of the exposition renders the subject matter accessible to senior undergraduates and graduate students of mathematics, physics and astrophysics.

Recent achievements in sunlight concentration techniques have increased the potential of solar power as a viable source of renewable energy. Through its critical analysis of current methods, Photovoltaic Conversion of Concentrated Sunlight provides a comprehensive treatment of the issues involved in the creation of an efficient and cost-effective sustainable power resource. The authors introduce significant new original research and offer an insight into previously inaccessible Russian studies. Logically structured, the text presents both theoretical and practical advances in the field. Features include:<br> * Discussion of fabrication problems for both terrestrial and space photovoltaic installations<br> * Investigation of the impact of resistive losses on the operation of solar cells and new procedures for measuring components of internal resistance<br> * Explanation of the semiconductor physics underlying photovoltaics<br> * Examination of the most efficient concentrator solar cell structures and materials plus exploration of ways to improve cell performance<br> * Original theoretical and experimental results on luminescence phenomena in concentrator cells<br> * Useful measurement techniques for the determination of diagnostic cell parameters<br> * Analysis of energy characteristics of photovoltaic installations with high and low concentration ratios<br> An invaluable asset to industrialists and academics concerned with semiconductors and photovoltaics, this book will also serve environmental scientists through its examination of the problems associated with large-scale use of this ecological technology.

The XIIlth General Assembly of the International Astronomical Union, held in Prague from 22 to 31 August, 1967, brought together more than 1800 active astron- omers from 40 countries. The agenda of the Assembly ranged from administrative questions to highly intricate scientific problems. Thirty-eight Presidents of the IAU Commissions contributed by their reports to a detailed survey of Astronomy for the period 1964-67. These reports were published in the Transactions of the IAU, Volume XIIIA. Transactions volume XIIIB bring the results of the administrative meetings and of the meetings of Commissions held during the General Assembly. The present volume is devoted to the most important scientific results of the General Assembly as presented in the Invited Discourses, Joint Discussions, and at Special Meetings. It is an established policy of the Union to invite prominent astronomers to hold, during the General Assembly, formal discourses on topics of major importance due to recent significant developments. These Invited Discourses cover, as a rule, broad fields of astronomical interest and are meant to give basic information also to scien- tists from other branches. Subjects which call for a more detailed technical approach are dealt with in the Joint Discussions or at Special Meetings. Here, invited speakers present authoritative surveys complemented by communications on current or envisaged projects. The proceedings of two other meetings, on Moon Probes and on Coordination of Solar Observations Made at Ground-based Observatories and with Space Vehicles, are of a sufficiently wide interest to warrant the inclusion into this volume.


Formation Of The Solar System

RRP $436.99

Analysis of the orbital motion of the Earth, the Moon and other planets and their satellites led to the discovery that all bodies in the Solar System are moving with the first cosmic velocity of their proto parents. The mean orbital velocity of each planet is equal to the first cosmic velocity of the Protosun, the radius of which is equal to the semi-major axis of the planet s orbit. The same applies for the planets satellites. All the small planets, comets, other bodies and the Sun itself follow this law, a finding that has also been proven by astronomical observations. The theoretical solutions based on the Jacobi dynamics explain the process of the system creation and decay, as well as the nature of Kepler s laws.

The Demon Queen Attacks To his own surprise, young Kellen, once the disappointing son of the great Mage who leads the City's Mage Council, has become a powerful Knight-Mage. Valued for his bravery and his skills as both wizard and warrior, Kellen joins the Elves' war councils. Yet he cannot convince the City of his birth that it is in terrible danger. Kellen's sister Idalia, a Wild Mage with great healing ability, has pledged her heart to Jermayan, a proud Elven warrior. Someday Idalia will pay a tragic Price for a world-saving work of Wild Magic, but until then, she will claim any joy life can offer her.
Jermayan, who has learned much fighting at Kellen's side and loving the human Idalia, finds that everything changes when he Bonds with a dragon while rescuing the Elf Prince and becomes the first Elven Mage in a thousand years.
Furious at her enemies' success with the dragon, the Demon Queen attacks in force. Light struggles against Dark, like flickering candle flames buried deep in the shadow of Obsidian Mountain.
