Book Description
Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.

Book Description
All Too Human is a new-generation political memoir, written from the refreshing perspective of one who got his hands on the levers of awesome power at an early age. At thirty, the author was at Bill Clinton's side during the presidential campaign of 1992, & for the next five years he was rarely more than a step away from the president & his other advisers at every important moment of the first term. What Liar's Poker did to Wall Street, this book will do to politics. It is an irreverent & intimate portrait of how the nation's weighty business is conducted by people whose egos & idiosyncrasies are no sturdier than anyone else's. Including sharp portraits of the Clintons, Al Gore, Dick Morris, Colin Powell, & scores of others, as well as candid & revelatory accounts of the famous debacles & triumphs of an administration that constantly went over the top, All Too Human is, like its author, a brilliant combination of pragmatic insight & idealism. It is destined to be the most important & enduring book to come out of the Clinton administration.

Book Description
An antidote to mathematical rigor mortis, teaching how to guess answers without needing a proof or an exact calculation. In problem solving, as in street fighting, rules are for fools: do whatever works—don't just stand there! Yet we often fear an unjustified leap even though it may land us on a correct result. Traditional mathematics teaching is largely about solving exactly stated problems exactly, yet life often hands us partly defined problems needing only moderately accurate solutions. This engaging book is an antidote to the rigor mortis brought on by too much mathematical rigor, teaching us how to guess answers without needing a proof or an exact calculation. In Street-Fighting Mathematics, Sanjoy Mahajan builds, sharpens, and demonstrates tools for educated guessing and down-and-dirty, opportunistic problem solving across diverse fields of knowledge—from mathematics to management. Mahajan describes six tools: dimensional analysis, easy cases, lumping, picture proofs, successive approximation, and reasoning by analogy. Illustrating each tool with numerous examples, he carefully separates the tool—the general principle—from the particular application so that the reader can most easily grasp the tool itself to use on problems of particular interest. Street-Fighting Mathematics grew out of a short course taught by the author at MIT for students ranging from first-year undergraduates to graduate students ready for careers in physics, mathematics, management, electrical engineering, computer science, and biology. They benefited from an approach that avoided rigor and taught them how to use mathematics to solve real problems.

Book Description
From the winner of the Turing Award and the Abel Prize, an introduction to computational complexity theory, its connections and interactions with mathematics, and its central role in the natural and social sciences, technology, and philosophy Mathematics and Computation provides a broad, conceptual overview of computational complexity theory—the mathematical study of efficient computation. With important practical applications to computer science and industry, computational complexity theory has evolved into a highly interdisciplinary field, with strong links to most mathematical areas and to a growing number of scientific endeavors. Avi Wigderson takes a sweeping survey of complexity theory, emphasizing the field’s insights and challenges. He explains the ideas and motivations leading to key models, notions, and results. In particular, he looks at algorithms and complexity, computations and proofs, randomness and interaction, quantum and arithmetic computation, and cryptography and learning, all as parts of a cohesive whole with numerous cross-influences. Wigderson illustrates the immense breadth of the field, its beauty and richness, and its diverse and growing interactions with other areas of mathematics. He ends with a comprehensive look at the theory of computation, its methodology and aspirations, and the unique and fundamental ways in which it has shaped and will further shape science, technology, and society. For further reading, an extensive bibliography is provided for all topics covered. Mathematics and Computation is useful for undergraduate and graduate students in mathematics, computer science, and related fields, as well as researchers and teachers in these fields. Many parts require little background, and serve as an invitation to newcomers seeking an introduction to the theory of computation. Comprehensive coverage of computational complexity theory, and beyond High-level, intuitive exposition, which brings conceptual clarity to this central and dynamic scientific discipline Historical accounts of the evolution and motivations of central concepts and models A broad view of the theory of computation's influence on science, technology, and society Extensive bibliography

Book Description
What is the secret of talent? How do we unlock it? This groundbreaking work provides readers with tools they can use to maximize potential in themselves and others. Whether you’re coaching soccer or teaching a child to play the piano, writing a novel or trying to improve your golf swing, this revolutionary book shows you how to grow talent by tapping into a newly discovered brain mechanism. Drawing on cutting-edge neurology and firsthand research gathered on journeys to nine of the world’s talent hotbeds—from the baseball fields of the Caribbean to a classical-music academy in upstate New York—Coyle identifies the three key elements that will allow you to develop your gifts and optimize your performance in sports, art, music, math, or just about anything. • Deep Practice Everyone knows that practice is a key to success. What everyone doesn’t know is that specific kinds of practice can increase skill up to ten times faster than conventional practice. • Ignition We all need a little motivation to get started. But what separates truly high achievers from the rest of the pack? A higher level of commitment—call it passion—born out of our deepest unconscious desires and triggered by certain primal cues. Understanding how these signals work can help you ignite passion and catalyze skill development. • Master Coaching What are the secrets of the world’s most effective teachers, trainers, and coaches? Discover the four virtues that enable these “talent whisperers” to fuel passion, inspire deep practice, and bring out the best in their students. These three elements work together within your brain to form myelin, a microscopic neural substance that adds vast amounts of speed and accuracy to your movements and thoughts. Scientists have discovered that myelin might just be the holy grail: the foundation of all forms of greatness, from Michelangelo’s to Michael Jordan’s. The good news about myelin is that it isn’t fixed at birth; to the contrary, it grows, and like anything that grows, it can be cultivated and nourished. Combining revelatory analysis with illuminating examples of regular people who have achieved greatness, this book will not only change the way you think about talent, but equip you to reach your own highest potential.

Book Description
*Finalist for the Pulitzer Prize for Biography* *Winner of the Los Angeles Times Prize for Biography* *Winner of the 2019 Hitchens Prize* "Portrays Holbrooke in all of his endearing and exasperating self-willed glory...Both a sweeping diplomatic history and a Shakespearean tragicomedy... If you could read one book to comprehend American's foreign policy and its quixotic forays into quicksands over the past 50 years, this would be it."--Walter Isaacson, The New York Times Book Review "By the end of the second page, maybe the third, you will be hooked...There never was a diplomat-activist quite like [Holbrooke], and there seldom has been a book quite like this -- sweeping and sentimental, beguiling and brutal, catty and critical, much like the man himself."--David M. Shribman, The Boston Globe Richard Holbrooke was brilliant, utterly self-absorbed, and possessed of almost inhuman energy and appetites. Admired and detested, he was the force behind the Dayton Accords that ended the Balkan wars, America's greatest diplomatic achievement in the post-Cold War era. His power lay in an utter belief in himself and his idea of a muscular, generous foreign policy. From his days as a young adviser in Vietnam to his last efforts to end the war in Afghanistan, Holbrooke embodied the postwar American impulse to take the lead on the global stage. But his sharp elbows and tireless self-promotion ensured that he never rose to the highest levels in government that he so desperately coveted. His story is thus the story of America during its era of supremacy: its strength, drive, and sense of possibility, as well as its penchant for overreach and heedless self-confidence. In Our Man, drawn from Holbrooke's diaries and papers, we are given a nonfiction narrative that is both intimate and epic in its revelatory portrait of this extraordinary and deeply flawed man and the elite spheres of society and government he inhabited.
