INTRODUCTION TO MECHANISMS. Machine. Combination of resistant bodies so arranged that by their. . means the mechanical forces of nature can be compelled to do. . work accompanied by certain determinate motion.. The concepts of differential topology form the center of many mathematical disciplines such as differential geometry and Lie group theory. Differential Manifolds presents to advanced undergraduates and graduate students the systematic study of the topological structure of smooth manifolds. Author Antoni A. Kosinski, Professor Emeritus of Mathematics at Rutgers University, offers an accessible approach to both the h-cobordism theorem and the classification of differential structures on spheres.How useful it is, noted the Bulletin of the American Mathematical Society, to have a single, short, well-written book on differential topology. This volume begins with a detailed, self-contained review of the foundations of differential topology that requires only a minimal knowledge of elementary algebraic topology. Subsequent chapters explain the technique of joining manifolds along submanifolds, the handle presentation theorem, and the proof of the h-cobordism theorem based on these constructions. There follows a chapter on the Pontriagin Construction—the principal link between differential topology and homotopy theory. The final chapter introduces the method of surgery and applies it to the classification of smooth structures of spheres. The text is supplemented by numerous interesting historical notes and contains a new appendix, The Work of Grigory Perelman, by John W. Morgan, which discusses the most recent developments in differential topology. This special edition of Apollo Expeditions to the Moon, an official NASA publication, commemorates the fiftieth anniversary of the July 20, 1969, Moon landing with a thrilling insider\'s view of the space program.  Essays by participants — engineers, astronauts, and administrators — recall the program\'s unprecedented challenges. Written in direct, jargon-free language, this compelling adventure features more than 160 dazzling color photographs and scores of black-and-white illustrations. Insights into management challenges as well as its engineering feats include contributions from Michael Collins, Buzz Aldrin, Alan Shepard, and other astronauts NASA administrator James E. Webb Christopher C. Kraft, head of the Mission Control Center and engineer Wernher von Braun. Their informative, exciting narratives explore the issues that set the United States on the path to the Moon, offer perspectives on the program\'s legacy, and examine the particulars of individual missions. Journalist Robert Sherrod chronicles the selection and training of astronauts. James Lovell, commander of the ill-fated Apollo 13, recounts the damaged ship\'s dramatic return to Earth. Geologist and Apollo 17 astronaut Harrison Schmitt discusses the lunar expeditions\' rich harvest of scientific information. These and other captivating firsthand accounts form an ideal introduction to the historic U.S. space program as well as fascinating reading for all ages. This new expanded edition includes a chronology of the Apollo project, additional photographs, and a new Foreword by historian Paul Dickson that offers a modern retrospective of the Moon landing, discussing its place in the world of space exploration and its impact on American history and culture.   Based on the famous series of lectures given at Göttingen by Professor Prandtl and enlarged with additional material on experimental methods by O. G. Tietjens, this volume presents practical applications of theoretical hydro- and aeromechanics. The methods it deals with can easily be followed by engineers, although advanced mathematics is used in the sections on airfoil.Coverage is wide, ranging from an introduction to flow in pipes to Dr. Prandtl\'s own work on boundary layers, drag, airfoil theory, and experimental methods. Of special interest are discussions of entry conditions for flow in a pipe turbulent flow in pipes and in the boundary layer the method of determining the drag of a body from the velocity and pressure of the wake measurement of pressure drop at the transition between laminar and turbulent flow  the laws of pressure drag, friction drag, and deformation drag application of the momentum theorem to the Kàrmàn trail experiments with the properties of slotted wings the airfoil of infinite length three-dimensional airfoil theory and experimental methods and apparatus (pressure and velocity measurements, drag measurements, wind tunnels, and visualizing flow phenomena). Pointing a satellite in the right direction requires an extremely complex system — one that describes the satellite\'s orientation and at the same time predicts and either uses or neutralizes external influences.From its roots in classical mechanics and reliance on stability theory to the evolution of practical stabilization ideas, Spacecraft Attitude Dynamics offers comprehensive coverage of environmental torques encountered in space energy dissipation and its effects on the attitude stability of spinning bodies motion equation for four archetypical systems derived and used repeatedly throughout the text orientation parameters (not limited to Euler angles) illustrations of key concepts with on-orbit flight data and typical engineering hardware, with examples of the implementation of dynamic ideas.Suitable as a text for advanced undergraduates and graduate students, this unified treatment is also a valuable reference for professional engineers studying the analysis and application of modern spacecraft attitude dynamics. The sole prerequisites are a fundamental knowledge of vector dynamics and matrix algebra. Over 250 diagrams appear throughout the text, along with extensive problem sets at the end of each chapter, 350 references (cited, interpreted, and placed in perspective to reinforce the material), and two helpful appendixes. This graduate-level treatment of aerodynamic theory opens with a survey of vector analysis and complex variables that presents readers with the basic tools for handling subsequent chapters. Topics include flow functions, airfoil construction and pressure distribution, finite and monoplane wings, spanwise load distribution for arbitrary wings, and many other subjects. 1951 edition A towering figure in intellectual history and one of the fathers of modern astronomy, the great mathematician Johannes Kepler (1571–1630) is best known for his discovery of the three laws of planetary motion, which paved the way for a dynamic explanation of the heavenly phenomena. At a time when the Ptolemaic view still prevailed in official circles, Kepler undertook to prove the truth of the Copernican world view and through exceptional perseverance and force of intellect achieved that goal. His epochal intellectual feats are completely and thoroughly described in this splendid work, considered the definitive biography of Kepler. Drawing on a wealth of primary sources, the author presents a fascinating and erudite picture of Kepler\'s scientific accomplishments, his public life (work with Tycho Brahe, the Danish astronomer mathematical appointments at Graz, Prague, and Linz pioneering work with calculus and optics, and more) and his personal life: childhood and youth, financial situation, his mother\'s trial as a witch, his own lifelong fear of religious persecution, his difficulties in choosing one of eleven possible young women as his second wife, and more, through his last years in Ulm and death in Regensburg.Until his death in 1956, Professor Max Caspar was the world\'s foremost Kepler scholar. He had spent over two-thirds of his life assembling, cataloging, describing, analyzing, and editing Kepler\'s works. To this biography he brought tremendous learning and passionate enthusiasm for his subject, creating an unsurpassed resource on the life and work of one of history\'s greatest scientific minds. Originally published in German and superbly translated into English by C. Doris Hellman, Kepler will fascinate scholars and general readers alike. This account of the evolution and coherence of fluid motion theory focuses on achievements by pioneering thinkers from Plato to Mach. This introduction to the history of science in the seventeenth century examines the so-called \'scientific revolution\' in terms of the interplay between two major themes. The Platonic-Pythagorean tradition looked on nature in geometric terms with the conviction that the cosmos was constructed according to the principles of mathematical order, while the mechanical philosophy conceived of nature as a huge machine and sought to explain the hidden mechanisms behind phenomena. Pursuing different goals, these two movements of thought tended to conflict with each other, and more than the obviously mathematical sciences were affected - the influence spread as far as chemistry and the life sciences. As this book demonstrates, the full fruition of the scientific revolution required a resolution of the tension between the two dominant trends. Epicyclic trains, oblique rollers, trip hammers, and lazy-tongs are among the ingenious mechanisms defined and illustrated in this intriguing collection. Spanning the first century of the Industrial Revolution, this 1868 compilation features simplified, concise illustrations of the mechanisms used in hydraulics, steam engines, pneumatics, presses, horologes, and scores of other machines.The movements of each of the 507 mechanisms are depicted in drawings on the left-hand page, and the facing page presents a brief description of the item\'s use and operation. Ranging from simple to intricately complex, the mechanisms offer a fascinating view of the variety of small components that constitute complex machinery. A detailed index provides easy reference to specific mechanisms.Inventors, tinkerers, and anyone with an interest in the history of invention and technology will find this volume a treasury of information and inspiration.
