First Man: The Life of Neil A. Armstrong
by James R. HansenSoon to be a major motion picture, this is the first—and only—definitive authorized account of Neil Armstrong, the man whose “one small step” changed history.When Apollo 11 touched down on the Moon’s surface in 1969, the first man on the Moon became a legend. In First Man, author James R. Hansen explores the life of Neil Armstrong. Based on over fifty hours of interviews with the intensely private Armstrong, who also gave Hansen exclusive access to private documents and family sources, this “magnificent panorama of the second half of the American twentieth century” (Publishers Weekly, starred review) is an unparalleled biography of an American icon. In this “compelling and nuanced portrait” (Chicago Tribune) filled with revelations, Hansen vividly recreates Armstrong’s career in flying, from his seventy-eight combat missions as a naval aviator flying over North Korea to his formative trans-atmospheric flights in the rocket-powered X-15 to his piloting Gemini VIII to the first-ever docking in space. For a pilot who cared more about flying to the Moon than he did about walking on it, Hansen asserts, Armstrong’s storied vocation exacted a dear personal toll, paid in kind by his wife and children. For the near-fifty years since the Moon landing, rumors have swirled around Armstrong concerning his dreams of space travel, his religious beliefs, and his private life. A penetrating exploration of American hero worship, Hansen addresses the complex legacy of the First Man, as an astronaut and as an individual. “First Man burrows deep into Armstrong’s past and present…What emerges is an earnest and brave man” (Houston Chronicle) who will forever be known as history’s most famous space traveler.
First Man: The Life of Neil A. Armstrong
by James R. HansenMarking the forty-fifth anniversary of Apollo 11's moon landing, First Man by James Hansen offers the only authorized glimpse into the life of America's most famous astronaut, Neil Armstrong--the man whose "one small step" changed history."The Eagle has landed." When Apollo 11 touched down on the moon's surface in 1969, the first man on the moon became a legend. In First Man, Hansen explores the life of Neil Armstrong. Based on over fifty hours of interviews with the intensely private Armstrong, who also gave Hansen exclusive access to private documents and family sources, this "magnificent panorama of the second half of the American twentieth century" (Publishers Weekly, starred review) is an unparalleled biography of an American icon. Upon his return to earth, Armstrong was honored and celebrated for his monumental achievement. He was also--as James R. Hansen reveals in this fascinating and important biography--misunderstood. Armstrong's accomplishments as engineer, test pilot, and astronaut have long been a matter of record, but Hansen's unprecedented access to private documents and unpublished sources and his interviews with more than 125 subjects (including more than fifty hours with Armstrong himself) yield this first in-depth analysis of an elusive American celebrity still renowned the world over. In a riveting narrative filled with revelations, Hansen vividly recreates Armstrong's career in flying, from his seventy-eight combat missions as a naval aviator flying over North Korea to his formative transatmospheric flights in the rocket-powered X-15 to his piloting Gemini VIII to the first-ever docking in space. These milestones made it seem, as Armstrong's mother Viola memorably put it, "as if from the very moment he was born--farther back still--that our son was somehow destined for the Apollo 11 mission." For a pilot who cared more about flying to the Moon than he did about walking on it, Hansen asserts, Armstrong's storied vocation exacted a dear personal toll, paid in kind by his wife and children. For the forty-five years since the Moon landing, rumors have swirled around Armstrong concerning his dreams of space travel, his religious beliefs, and his private life. In a penetrating exploration of American hero worship, Hansen addresses the complex legacy of the First Man, as an astronaut and as an individual. In First Man, the personal, technological, epic, and iconic blend to form the portrait of a great but reluctant hero who will forever be known as history's most famous space traveler.

Feed-Forward: On the Future of Twenty-First-Century Media
by Mark B. N. HansenEven as media in myriad forms increasingly saturate our lives, we nonetheless tend to describe our relationship to it in terms from the twentieth century: we are consumers of media, choosing to engage with it. In Feed-Forward, Mark B. N. Hansen shows just how outmoded that way of thinking is: media is no longer separate from us but has become an inescapable part of our very experience of the world. Drawing on the speculative empiricism of philosopher Alfred North Whitehead, Hansen reveals how new media call into play elements of sensibility that greatly affect human selfhood without in any way belonging to the human. From social media to data-mining to new sensor technologies, media in the twenty-first century work largely outside the realm of perceptual consciousness, yet at the same time inflect our every sensation. Understanding that paradox, Hansen shows, offers us a chance to put forward a radically new vision of human becoming, one that enables us to reground the human in a non-anthropocentric view of the world and our experience in it.
Aerodynamics of Wind Turbines
by Martin O. HansenAerodynamics of Wind Turbines is the established essential text for the fundamental solutions to efficient wind turbine design. Now in its third edition, it has been substantially updated with respect to structural dynamics and control. The new control chapter now includes details on how to design a classical pitch and torque regulator to control rotational speed and power, while the section on structural dynamics has been extended with a simplified mechanical system explaining the phenomena of forward and backward whirling modes. Readers will also benefit from a new chapter on Vertical Axis Wind Turbines (VAWT). Topics covered include increasing mass flow through the turbine, performance at low and high wind speeds, assessment of the extreme conditions under which the turbine will perform and the theory for calculating the lifetime of the turbine. The classical Blade Element Momentum method is also covered, as are eigenmodes and the dynamic behaviour of a turbine. The book describes the effects of the dynamics and how this can be modelled in an aeroelastic code, which is widely used in the design and verification of modern wind turbines. Furthermore, it examines how to calculate the vibration of the whole construction, as well as the time varying loads and global case studies.
Small Antenna Handbook
by Robert C. Hansen Robert E. CollinUniquely explains in detail how small antennas work and ways to improve their performance This book addresses the recent significant theoretical and practical developments in the electrically small antenna (ESA) area. Examining antenna designs that work as well as those that have limitations, it offers the latest information on electromagnetically coupled structures and improving bandwidth using spherical helix dipoles, the exact derivation of Q for electrically small antennas for both TE and TM modes, a new simplified Q formula developed by the authors, and discussions of metamaterials and computer model accuracy for ESA. The book begins with detailed electromagnetic derivations of Chu and Thal Q formulations, formulas for Q when U or E cores are used, and effects of loss on Q. It also includes a treatise on bandwidth and matching, and Foster's reactance theorem, as well as up-to-date coverage of canonical antennas: dipoles, loops, self-resonant ESA, PIFA, and dielectric resonator antennas. Just as this book offers the concrete facts on relevant developments in the field, it also clears up confusion regarding findings that have not turned out to be useful. Presented here are antenna ideas that are clever but with performance numbers that are poor, as well as eighteen more antenna ideas that are simply not to be believed. The book concludes with recent data on the use of self-resonant elements in superdirective antennas and new delay line data on superconducting antennas. Each chapter features extensive references and an author list. In addition, helpful appendices cover a world history of ESA, antenna terms important to ESA, a paper on NIM shells enclosing an ESA dipole, and analytical errors associated with perfect lenses and sub-wavelength focusing. Small Antenna Handbook is ideal for practicing engineers in the telecommunications and national defense areas, as well as for upper-level undergraduate and graduate students.
