Welcome to Gramarye the place witches, warlocks, elves, and gnomes are genuine; the place a spoiled girl-queen and a military of teen witches and ragtag beggars conflict an overpowering strength of insurgent knights and time-travelling anarchists, for the way forward for the main specific, and maybe most vital, planet within the galaxy.
this is often what cynical, hard-bitten intergalactic secret agent Rod Gallowglass faces while he and his robotic horse Fess, attempt to carry peace and democracy to this magic-ridden Renaissance-age society. Rod s venture is threatened at each flip through anarchists, communists, and double-dealing royalists enjoying vicious political energy video games. issues are made even worse whilst Rod's complicated know-how will get him classified a warlock despite his consistent denials. aid comes from the main unforeseen resources while he meets an historical ghost, the King of the Elves, and the main robust witch on the earth.
this can be sword-and-sorcery with a witty, edgy, wry twist.
The vintage technology fable novel by way of Christopher Stasheff involves existence in eleven hours of dramatic audio, that includes famous narrator Dennis Regan, and an entire cast.

Archaeoastronomy is a self-discipline pioneered at Stonehenge and different megalithic websites in Britain and France. Many websites within the southwestern usa have yielded proof of the prehistoric Anasazi’s severe curiosity in astronomy, just like that of the megalithic cultures of Europe.
The authors describe the astronomical alignments on the famous websites of Chaco Canyon and Hovenweep and current new proof, in keeping with fresh box paintings of alignments at Yellow Jacket, Chimney Rock, and Mesa Verde.
Drawing at the archaeological proof, ethnographical parallels with historical pueblo peoples, and mythology from different cultures world wide, the authors current theories in regards to the that means and serve as of the mysterious stone alignments and architectural orientations of the prehistoric Southwest.

The promise of MEMS for aerospace purposes has been germinating for years, and present advances carry the sphere to the very cusp of fruition. Reliability is leader one of the demanding situations restricting the deployment of MEMS applied sciences in area, because the requirement of 0 failure in the course of the undertaking is kind of stringent for this burgeoning box. MEMS and Microstructures in Aerospace functions offers all of the priceless instruments to beat those hindrances and take MEMS from the lab bench to past the exosphere.
The publication starts with an outline of MEMS improvement and gives numerous demonstrations of earlier and present examples of MEMS in area. From this platform, the dialogue builds to fabrication applied sciences; the impact of house environmental components on MEMS units; and micro applied sciences for area structures, instrumentation, communications, thermal keep an eye on, information navigation and keep watch over, and propulsion. next chapters discover elements universal to all the defined structures, reminiscent of MEMS packaging, dealing with and illness keep watch over, fabric choice for particular purposes, reliability practices for layout and alertness, and insurance practices.
Edited and contributed through a great crew of prime specialists from undefined, academia, and nationwide laboratories, MEMS and Microstructures in Aerospace purposes illuminates the trail towards qualifying and integrating MEMS units and tools into destiny area missions and constructing leading edge satellite tv for pc structures.

This publication examines, for the 1st time, the clinical tactics devised by way of Ptolemy (second century advert) for investigating the constructions underlying musical melody, a venture that he conceived as heavily on the topic of astronomy. Ptolemy's account of his equipment is surprisingly specific, and he pursues them faithfully. via offering an research of Ptolemy's refined theoretical gear, his concepts for integrating idea with remark, and his meticulous directions for the layout and behavior of experimental assessments, the ebook deals historians of technology a brand new starting-point for wider stories of old clinical strategy.

Download E-books The Paraboloidal Reflector Antenna in Radio Astronomy and Communication: Theory and Practice (Astrophysics and Space Science Library) PDF
Radio astronomers have built suggestions of calibration of enormous reflector antennas with radio astronomical equipment, yet those haven't been comprehensively defined. this article goals to fill this hole, taking a pragmatic method of the characterisation of antennas. All calculations and ends up in the shape of tables and figures were made with Mathematica by means of Wolfram study. The reader can use the approaches for the implementation of his personal enter data.

There’s no relaxation for a Longknife—even if you’re a newlywed. Vice Admiral Kris Longknife’s honeymoon will get cancelled whilst she hears that the distance raider’s domestic international can have been chanced on. discovering the place the raiders got here from may be the key to saving humanity. If merely uncovering their secrets and techniques was once that easy…
As Kris returns domestic, she finally ends up tangling with a mutinous workforce decided to take off on their lonesome. The dissident workforce leads Kris directly right into a new mess—a process jam-packed with unusual, lethal enemies poised to wipe one other sentient civilization out of life. Kris and her squadron are able to hinder overall annihilation, however the mutineers produce other plans…

Carl Sagan, author and scientist, returns from the frontier to inform us approximately how the realm works. In his delightfully down-to-earth type, he explores and explains a mind-boggling way forward for clever robots, extraterrestrial lifestyles and its consquences, and different provocative, interesting quandries of the long run that we wish to see at the present time.

The cosmic microwave history (CMB) is the radiation left over from the large Bang. fresh research of the fluctuations during this radiation has given us helpful insights into our Universe and its parameters. studying the speculation of CMB and up to date advancements, this textbook begins with a short creation to trendy cosmology and its major successes, via a radical derivation of cosmological perturbation idea. It then explores the iteration of preliminary fluctuations by means of inflation. The Boltzmann equation governs the evolution of CMB anisotropies and polarization is derived utilizing the full angular momentum procedure. Cosmological parameter estimation and the lensing of CMB fluctuations and spectral distortions also are mentioned. This textbook is the 1st to include an entire derivation of the idea of CMB anisotropies and polarization. excellent for graduate scholars and researchers during this box, it comprises end-of-chapter workouts, and ideas to chose workouts are supplied.

Starting with the fundamental components that differentiate area courses from different administration demanding situations, area application administration explains via thought and instance of actual courses from world wide, the philosophical and technical instruments had to effectively deal with huge, technically complicated area courses either within the executive and advertisement atmosphere. Chapters handle either structures and configuration administration, the administration of threat, estimation, size and keep watch over of either investment and this system time table, and the constitution of the aerospace all over the world.
