This book develops an original theory of the search for space objects, on which only crude orbital information is known. It uses a special principle to construct a plan for searching for such objects through optical or radar sensors. This principle maximally eliminates the loss of the sought-for object and provides an economical use of the resources used in the search. This book will be of great interest for astronomers-observers, space control services, space researchers, and students at technical universities.

Stan Allen is an architect and educator who has won global acclaim, primarily for his work in town planning and his influential 1996 essay "Field Conditions." His new book Situated Objects shows a unique facet of his creative process: a selection of small buildings and projects on rural sites, most of them situated within the landscape of the Hudson Valley, New York. They demonstrate an approach to architecture that engages in a dialogue with this partly wild and wholly non-urban environment that lies just outside the gates of New York City. The projects are presented in drawings and a rich array of images by celebrated photographer Scott Benedict. They are arranged in three thematic categories: Outbuildings, Material Histories, and New Natures, supplemented by the architect's writings and essays contributed by Helen Thomas and Jesús Vassallo. The first book on Stan Allen's buildings, Situated Objects highlights Allen's personal engagement with American material traditions, the conventions of architectural drawing, and the challenge of building with nature.
