Does Elinor fight for the Par, the creatures that enslaved her, or does she let the humans die along with everyone else?

    As recounted by Ben Rich, the operation's brilliant boss for nearly two decades, the chronicle of Lockheed's legendary Skunk Works is a drama of cold war confrontations and Gulf War air combat, of extraordinary feats of engineering & achievement against fantastic odds. Here are up-close portraits of the maverick band of scientists & engineers who made the Skunk Works so renowned. Filled with telling personal anecdotes & high adventure, with narratives from the CIA & from Air Force pilots who flew the many classified, risky missions, this book is a portrait of the most spectacular aviation triumphs of the 20th century.

    But most of all is it a story about how we all search for meaning in pursuit and fulfillment of our dreams …

    It has, among many other achievements, revealed thousands of galaxies in what seemed to be empty patches of sky; transformed our knowledge of black holes; found dwarf planets with moons orbiting other stars; and measured precisely how fast the universe is expanding. In Handprints on Hubble, retired astronaut Kathryn Sullivan describes her work on the NASA team that made all of this possible. Sullivan, the first American woman to walk in space, recounts how she and other astronauts, engineers, and scientists launched, rescued, repaired, and maintained Hubble, the most productive observatory ever built.Along the way, Sullivan chronicles her early life as a “Sputnik Baby,” her path to NASA through oceanography, and her initiation into the space program as one of “thirty-five new guys.” (She was also one of the first six women to join NASA's storied astronaut corps.) She describes in vivid detail what liftoff feels like inside a spacecraft (it's like “being in an earthquake and a fighter jet at the same time”), shows us the view from a spacewalk, and recounts the temporary grounding of the shuttle program after the Challenger disaster.Sullivan explains that “maintainability” was designed into Hubble, and she describes the work of inventing the tools and processes that made on-orbit maintenance possible. Because in-flight repair and upgrade was part of the plan, NASA was able to fix a serious defect in Hubble's mirrors—leaving literal and metaphorical “handprints on Hubble.”Handprints on Hubble was published with the support of the MIT Press Fund for Diverse Voices.

    A strong gravitational wave will briefly change that distance by less than the thickness of a human hair. We have perhaps less than a few tenths of a second to perform this measurement. And we don’t know if this infinitesimal event will come next month, next year or perhaps in thirty years.In 1916 Einstein predicted the existence of gravitational waves: miniscule ripples in the very fabric of spacetime generated by unfathomably powerful events. If such vibrations could somehow be recorded, we could observe our universe for the first time through sound: the hissing of the Big Bang, the whale-like tunes of collapsing stars, the low tones of merging galaxies, the drumbeat of two black holes collapsing into one. For decades, astrophysicists have searched for a way of doing so…In 2016 a team of hundreds of scientists at work on a billion-dollar experiment made history when they announced the first ever detection of a gravitational wave, confirming Einstein’s prediction. This is their story, and the story of the most sensitive scientific instrument ever made: LIGO.Based on complete access to LIGO and the scientists who created it, Black Hole Blues provides a firsthand account of this astonishing achievement: a compelling, intimate portrait of cutting-edge science at its most awe-inspiring and ambitious.

    While describing awe-inspiring technical achievements, the authors go beyond the missions and the competition of the space race to focus on the people who made it all possible. Their book explores the inspirations, ambitions, personalities, and experiences of the select few whose driving ambition was to fly to the moon. Drawing on interviews with astronauts, cosmonauts, their families, technicians, and scientists, as well as rarely seen Soviet and American government documents, the authors craft a remarkable story of the golden age of spaceflight as both an intimate human experience and a rollicking global adventure. From the Gemini flights to the Soyuz space program to the earliest Apollo missions, including the legendary first moon landing, their book draws a richly detailed picture of the space race as an endeavor equally endowed with personal meaning and political significance.

    The solved exercises cover all of the techniques discussed in the text, and include step-by-step instruction on working through the algorithms.
