Intended to create life from nothingness, the Genesis Device had the potential to become a weapon of awe-inspiring destructiveness, capable of rearranging matter and life energy on a planetary scale. After the cataclysmic explosion of the Genesis Planet, and the Klingon Empire's attempt to steal the top-secret technology for its own military purposes, Starfleet wisely decided to destroy all data and records on Project Genesis, hoping to bury its deadly secrets forever. Nearly a century later, all that remains of Genesis is the knowledge stored in the mind of an elderly, almost-forgotten scientist namedDr. Carol Marcus. But Dr. Marcus has gone missing, and a menace from bygone days has come rushing back with a vengeance. Sweeping across the Alpha Quadrant at a terrifying speed, a mysterious wave of energy is wiping out populations of entire planets, rearranging matter on a molecular level to create bizarre new landscapes and life-forms. The Starship Enterprise™, commanded by Captain Jean-Luc Picard, is the first Starfleet vessel to discover the threat, but Picard and his crew are not the only ones in danger. Billions of living beings and hundreds of inhabited planets lie in the path of the mutagenic wave, which is expanding outward as it traverses the cosmos. Earth and the Romulan Empire face total obliteration. To discover the origin of the wave, Picard and his crew must probe the long-buried mysteries of the past. But even if he can uncover the shocking history of the Genesis Wave, is there any way to save the future from its unleashed fury? The Genesis Wave, Book One, is the beginning of an apocalyptic two-part adventure that will pit the desperate crew of the Starship Enterprise against a disaster of galactic proportions.

An extensive pointing calibration program for the drive system and mount of the AFCRL 29-ft millimeter-wave antenna is described. The optical pointing accuracy was determined by measuring the positioning errors of the optical axis of the antenna. Since all sources of optical pointing errors produce equivalent RF errors, all RF errors except those produced by feed system and reflector asymmetry are determined. A brief description of the antenna together with the integrated IBM 1800 data aquisition and control system, tracking software, and an accurate time-synchronization method are presented. The star tracking program, which includes a method of star selection, precession correction, and refraction correction, is described. The analysis and derivation of the various pointing error parameters used to determine the best-fitting functions that characterize the positional errors are presented. Next, the star data are reduced by fitting the nightly error measurements to the best-fitting error function from which the values of the error parameters that take into account the servo, collimation, azimuth plane tilt, elevation axis skewness, and residual refraction are determined. Finally, the results of the star data analysis and statistical data are presented. The rms residual optical pointingg error, after pointin calibration, averaged about 3 percent of the antenna beamwidth, that is, 7.5 arc seconds in both azimuth and elevation. (Author).

The highly-anticipated finale to the New York Times bestselling 5th Wave series. Includes an exclusive diary entry from Cassie! The enemy is Other. The enemy is us. They’re down here, they’re up there, they’re nowhere. They want the Earth, they want us to have it. They came to wipe us out, they came to save us. But beneath these riddles lies one truth: Cassie has been betrayed. So has Ringer. Zombie. Nugget. And all 7.5 billion people who used to live on our planet. Betrayed first by the Others, and now by ourselves. In these last days, Earth’s remaining survivors will need to decide what’s more important: saving themselves . . . or saving what makes us human. Praise for The Last Star “Yancey’s prose remains achingly precise, and this grows heavier, tighter, and more impossible to put down as the clock runs out…this blistering finale proves the truth of the first two volumes: it was never about the aliens.”—Booklist, starred review “A haunting, unforgettable finale.”—Kirkus Reviews “Yancey doesn’t hit the breaks for one moment, and the action is intense, but the language always stays lyrical and lovely. It’s a satisfying end to an impressive trilogy, true to the characters and the world Yancey created.”—Entertainment Weekly “Yancey has capped off his riveting series with a perfect ending.”—TeenReads.com “[T]he ending provides both satisfaction and heartbreak.”—Publishers Weekly “Yancey's writing is just as solid and descriptive as in the first two books….What Yancey does beautifully is reveal the human condition.”—Examiner.com "Rick Yancey sticks the (alien) landing in the action-packed finale to his The 5th Wave invasion saga . . . . And the author gives us a major dose of girl power as well, pairing Cassie and Ringer for an uneasy alliance that provides the best moments in this fantastic series’ thought-provoking and satisfying conclusion.”—USA Today Praise for The 5th Wave Now a major motion picture starring Chloë Grace Moretz "Remarkable, not-to-be-missed-under-any-circumstances."—Entertainment Weekly "A modern sci-fi masterpiece . . ."—USAToday.com "Wildly entertaining . . . I couldn't turn the pages fast enough."—Justin Cronin, The New York Times Book Review Praise for The Infinite Sea “Heart-pounding pacing, lyrical prose and mind-bending twists . . .”—The New York Times Book Review “Impressively improves on the excellent beginning of the trilogy.”—USA Today “An epic sci-fi novel with all the romance, action, and suspense you could ever want.”—Seventeen.com Books in the series: The 5th Wave (The First Book of The 5th Wave) The Infinite Sea (The Second Book of The 5th Wave) The Last Star (The Third Book of the The 5th Wave)

This most up-to-date, one-stop reference combines coverage of both theory and observational techniques, with introductory sections to bring all readers up to the same level. Written by outstanding researchers directly involved with the scientific program of the Laser Interferometer Gravitational-Wave Observatory (LIGO), the book begins with a brief review of general relativity before going on to describe the physics of gravitational waves and the astrophysical sources of gravitational radiation. Further sections cover gravitational wave detectors, data analysis, and the outlook of gravitational wave astronomy and astrophysics.
