Book Description
Seated in a sun-lit corner of his 17th century Dutch house, his hand touching a celestial globe, Johannes Vermeer's "Astronomer" seems to pon der about the mysteries of the universe. We might make the trip to Paris and ask him, in the Louvre, what precisely is on his mind. Unfortunately, there will be no answer. But we do know what his mind was not on. It was not on the approaching deadlines for the proposals he would have to write for getting funds and telescope-time, not on the meeting of the observing programs committee, not on his refereeing duty for the journal Astronomy & Astrophysics, nor on his university's tightening budget for science. In the Kapteyn Institute at Groningen I stand face to face with the im pressive portrait of J.C. Kapteyn, painted in the year 1918. Seated at his desk he is doing his calculations with pen, pencil and tables, perhaps check ing the work of his skilled staff of human computers. Early in his career he had completed his magnum opus, the Cape Photographic Durchmusterung in collaboration with his close friend David Gill at Capetown, South Africa.

Book Description
When I wasa child, growing up in South America,I often went camping in the wild and hence had direct access to the wondrous Southern sky; the Southern Cross was all mine at the time. Little did I know then that the study of the sky would take such a huge importance in my life, and that in the end astronomy and astrophysics would in many ways become my country and my religion. I have lived in several di?erent countries, and when asked my nationality, I am always very tempted to reply: astronomer. I started as a theorist, and my only dream in my youth was to spend nights thinking and calculating, with paper and pencil, and to have the impression by dawn that I had understood something new. So at the time astronomy was seen or dreamt by me as a solitary endeavour, with periodic encounters with my wise adviser and professors; it is this model that I adopted when doing my PhD work. My generation has lived through many revolutions of all kinds. Those in astronomy, I believe, remain particularly remarkable, and I am a true product of them. Now, I elect to live and work in large organizations, and to share my endeavours with many people. And I relish the series of Andr ́ e Heck on Organizations and Strategies in Astronomy, which help us recover our memories, reconstitute our own story, and read with glee about our neighbouring or far-away colleagues.

Book Description
Every night, astronomers use a new generation of giant telescopes at observatories around the world to study phenomena at the forefront of science. By focusing on the history of the Gemini ObservatoryÑtwin 8-meter telescopes located on mountain peaks in Hawaii and ChileÑGiant Telescopes tells the story behind the planning and construction of modern scientific tools, offering a detailed view of the technological and political transformation of astronomy in the postwar era. Drawing on interviews with participants and archival documents, W. Patrick McCray describes the ambitions and machinations of prominent astronomers, engineers, funding patrons, and politicians in their effort to construct a modern facility for cutting-edge scienceÑand to establish a model for international cooperation in the coming era of Òmegascience.Ó His account details the technological, institutional, cultural, and financial challenges that scientists faced while planning and building a new generation of giant telescopes. Besides exploring how and why scientists embraced the promise and potential of new technologies, he considers how these new tools affected what it means to be an astronomer. McCrayÕs book should interest anyone who desires a deeper understanding of the science, technology, and politics behind finding our place in the universe.

Book Description
The pilot boat just moved away and'its lights are already fading towards the coast of Northeastern Queensland over which Saturn is going to set. There is still quite some time to go before dawn. The big ship has now regained her cruise speed following its roughly northwesterly route in the South Coral Sea along the chain of nearby reefs. Few people are around at this time, except a dozen early birds sharing some 'shipshaping' exercise on the top deck and taking advantage of the relative coolness of the night. On my way down to the stateroom, I cannot but stop once more in front of that elegant composition by British artist Brigid Collins (1963-) hanging in the monumental staircase between Decks 7 and 8. That piece 2 of art, a 1.8x 1.8m oil on canvas plus collage entitled Berinl in honour of the Danish explorer, gathers together many navigation-related themes of the time: Suns, Moons, planets, sky maps, astrolabes, small telescopes, as well as drawings, diagrams and charts of all kinds. It is somehow a digest of how astronomical information was then collected, made available, and used.

Book Description
The sliding mode control methodology has proven effective in dealing with complex dynamical systems affected by disturbances, uncertainties and unmodeled dynamics. Robust control technology based on this methodology has been applied to many real-world problems, especially in the areas of aerospace control, electric power systems, electromechanical systems, and robotics. Sliding Mode Control and Observation represents the first textbook that starts with classical sliding mode control techniques and progresses toward newly developed higher-order sliding mode control and observation algorithms and their applications. The present volume addresses a range of sliding mode control issues, including: *Conventional sliding mode controller and observer design *Second-order sliding mode controllers and differentiators *Frequency domain analysis of conventional and second-order sliding mode controllers *Higher-order sliding mode controllers and differentiators *Higher-order sliding mode observers *Sliding mode disturbance observer based control *Numerous applications, including reusable launch vehicle and satellite formation control, blood glucose regulation, and car steering control are used as case studies Sliding Mode Control and Observation is aimed at graduate students with a basic knowledge of classical control theory and some knowledge of state-space methods and nonlinear systems, while being of interest to a wider audience of graduate students in electrical/mechanical/aerospace engineering and applied mathematics, as well as researchers in electrical, computer, chemical, civil, mechanical, aeronautical, and industrial engineering, applied mathematicians, control engineers, and physicists. Sliding Mode Control and Observation provides the necessary tools for graduate students, researchers and engineers to robustly control complex and uncertain nonlinear dynamical systems. Exercises provided at the end of each chapter make this an ideal text for an advanced course taught in control theory.
