This book describes a revolutionary new approach to determining low energy routes for spacecraft and comets by exploiting regions in space where motion is very sensitive (or chaotic). It also represents an ideal introductory text to celestial mechanics, dynamical systems, and dynamical astronomy. Bringing together wide-ranging research by others with his own original work, much of it new or previously unpublished, Edward Belbruno argues that regions supporting chaotic motions, termed weak stability boundaries, can be estimated. Although controversial until quite recently, this method was in fact first applied in 1991, when Belbruno used a new route developed from this theory to get a stray Japanese satellite back on course to the moon. This application provided a major verification of his theory, representing the first application of chaos to space travel. Since that time, the theory has been used in other space missions, and NASA is implementing new applications under Belbruno's direction. The use of invariant manifolds to find low energy orbits is another method here addressed. Recent work on estimating weak stability boundaries and related regions has also given mathematical insight into chaotic motion in the three-body problem. Belbruno further considers different capture and escape mechanisms, and resonance transitions. Providing a rigorous theoretical framework that incorporates both recent developments such as Aubrey-Mather theory and established fundamentals like Kolmogorov-Arnold-Moser theory, this book represents an indispensable resource for graduate students and researchers in the disciplines concerned as well as practitioners in fields such as aerospace engineering.
When a leaf falls on a windy day, it drifts and tumbles, tossed every which way on the breeze. This is chaos in action. In Fly Me to the Moon, Edward Belbruno shows how to harness the same principle for low-fuel space travel--or, as he puts it, "surfing the gravitational field." Belbruno devised one of the most exciting concepts now being used in space flight, that of swinging through the cosmos on the subtle fluctuations of the planets' gravitational pulls. His idea was met with skepticism until 1991, when he used it to get a stray Japanese satellite back on course to the Moon. The successful rescue represented the first application of chaos to space travel and ushered in an emerging new field. Part memoir, part scientific adventure story, Fly Me to the Moon gives a gripping insider's account of that mission and of Belbruno's personal struggles with the science establishment. Along the way, Belbruno introduces readers to recent breathtaking advances in American space exploration. He discusses ways to capture and redirect asteroids; presents new research on the origin of the Moon; weighs in on discoveries like 2003 UB313 (now named Eris), a dwarf planet detected in the far outer reaches of our solar system--and much more. Grounded in Belbruno's own rigorous theoretical research but written for a general audience, Fly Me to the Moon is for anybody who has ever felt moved by the spirit of discovery.

This collection includes six previously uncollected short stories, an analysis of Edward Bellamy's newspaper writings, much unpublished material about him and a number of excerpts from his notebooks.
This Pulitzer Prize-winning autobiography charmingly chronicles the life of Edward Bok, the longtime editor of The Ladies Home Journal and a noted philanthropist. Bok wrote of his eventful life, "Every life has some interest and significance; mine, perhaps, a special one.

This book was to have been written in 1914, when I foresaw some leisure to write it, for I then intended to retire from active editorship. But the war came, an entirely new set of duties commanded, and the project was laid aside. Its title and the form, however, were then chosen. By the form I refer particularly to the use of the third person. I had always felt the most effective method of writing an autobiography, for the sake of a better perspective, was mentally to separate the writer from his subject by this device. Moreover, this method came to me very naturally in dealing with the Edward Bok, editor and publicist, whom I have tried to describe in this book, because, in many respects, he has had and has been a personality apart from my private self. I have again and again found myself watching with intense amusement and interest the Edward Bok of this book at work. I have, in turn, applauded him and criticised him, as I do in this book. Not that I ever considered myself bigger or broader than this Edward Bok: simply that he was different. His tastes, his outlook, his manner of looking at things were totally at variance with my own. In fact, my chief difficulty during Edward Bok's directorship of The Ladies' Home Journal was to abstain from breaking through the editor and revealing my real self. Several times I did so, and each time I saw how different was the effect from that when the editorial Edward Bok had been allowed sway. Little by little I learned to subordinate myself and to let him have full rein. But no relief of my life was so great to me personally as his decision to retire from his editorship. My family and friends were surprised and amused by my intense and obvious relief when he did so. Only to those closest to me could I explain the reason for the sense of absolute freedom and gratitude that I felt. Since that time my feelings have been an interesting study to myself. There are no longer two personalities. The Edward Bok of whom I have written has passed out of my being as completely as if he had never been there, save for the records and files on my library shelves. It is easy, therefore, for me to write of him as a personality apart: in fact, I could not depict him from any other point of view. To write of him in the first person, as if he were myself, is impossible, for he is not.
