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.
Flight Without Limits Large-Format Edition (Magazine Style) The novel is Science Fiction - a space journey with the freedom to move, to love, to choose, to live. Imagine, traveling in an instant to wherever you want to be! The universe is your playground. Thought becomes expression. This is science fiction indeed. But maybe mentally it shouldn't be. The novel is about a space voyage to Alpha Centauri, the nearest solar system to our own. It starts as a high tech voyage, and then becomes much more than that. It links up with a future that is moving backwards. It also comes upon a present that has no future, but for which a future is created that has no limits. Of course, being able to travel to wherever one may want to be has certain social advantages, and also challenges. Of course, politically, this capability has even greater challenges attached. Some people say that we will never have the capability, to go physically in an instant wherever we want to be. They might be right. But we do have that kind of capability mentally, in the world of science, romance, and spirituality, all of which are threaded through the novel. You may find that when you return, you have left some of the old limits behind. (http: //www.ice-age-ahead-iaa.ca
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.
Humans have long thought that planetary systems similar to our own should exist around stars other than the Sun, yet the search for planets outside our Solar System has had a dismal history of discoveries that could not be confirmed. However, this all changed in 1995, with the past decade witnessing astonishing progress in this field; we now know of more than 200 extrasolar planets. These findings mark crucial milestones in the search for extraterrestrial life - arguably one of the most intriguing endeavors of modern science. These proceedings from the Space Telescope Science Institute Symposium on Extrasolar Planets explore one of the hottest topics in astronomy today. Discussions include the Kepler mission, observational constraints on dust disk lifetimes and the implications for planet formation, and gravitational instabilities in protoplanetary disks. With review papers written by world experts in their fields, this is an important resource on extrasolar planets.
A gothic novelette about a young hunter who accidentally interrupts a wizard's spell which literally turns him into a living shadow, only able to venture into the world by night. He is doomed to spend the rest of eternity haunting the area where he was enchanted, hunting an elusive, ethereal deer night after night. Although his night vision becomes enhanced, and he is able to soar through the air with a shadow's weightlessness, interactions with other people leave him with such intense anxiety that he has no choice but to avoid them altogether. Help and danger collide when he encounters an injured runaway, whom he decides to help, despite the personal pain it causes. A stand alone prequel to the novel, "The Thirteenth Hour," by the same author. Approximately 11,000 words.
