The 6th IAA Symposium on Small Satellites for Earth Observation, initiated by the International Academy of Astronautics (IAA), was again hosted by DLR, the German Aerospace Center. The participation of scientists, engineers, and managers from 24 countries reflected the high interest in the use of small satellites for dedicated missions applied to Earth observation. The contributions showed that dedicated Earth observation missions cover a wide range of very different tasks.

This book explores the problematic relationship between education, social justice and the State, against the background of comparative education research. The book critiques the status quo of stratified school systems, and the unequal distribution of cultural capital and value added schooling. The authors address one of today’s most pressing questions: Are social, economic and cultural divisions between the nations, between school sectors, between schools and between students growing or declining?

Cambridge English for Schools Practice Tests have been designed to familiarise students with the level and format of the Cambridge English Key, Preliminary and First (previously known as KET, PET and FCE) for Schools examinations. Students can be assured that they will receive the relevant, up-to-date, appropriate training to successfully undertake these tests. The guidance and tips sections advise students on how to approach each part of the examination and allow them to improve the skills required.

Mirror symmetry began when theoretical physicists made some astonishing predictions about rational curves on quintic hypersurfaces in four-dimensional projective space. Understanding the mathematics behind these predictions has been a substantial challenge. This book is the first completely comprehensive monograph on mirror symmetry, covering the original observations by the physicists through the most recent progress made to date. Subjects discussed include toric varieties, Hodge theory, Kahler geometry, moduli of stable maps, Calabi-Yau manifolds, quantum cohomology, Gromov-Witten invariants, and the mirror theorem. This title features: numerous examples worked out in detail; an appendix on mathematical physics; an exposition of the algebraic theory of Gromov-Witten invariants and quantum cohomology; and, a proof of the mirror theorem for the quintic threefold.

A gloriously illustrated examination of the origins and development of the nude as an artistic subject in Renaissance Europe Reflecting an era when Europe looked to both the classical past and a global future, this volume explores the emergence and acceptance of the nude as an artistic subject. It engages with the numerous and complex connotations of the human body in more than 250 artworks by the greatest masters of the Renaissance. Paintings, sculptures, prints, drawings, illuminated manuscripts, and book illustrations reveal private, sometimes shocking, preoccupations as well as surprising public beliefs—the Age of Humanism from an entirely new perspective. This book presents works by Albrecht Dürer, Lucas Cranach, and Martin Schongauer in the north and Donatello, Raphael, and Giorgione in the south; it also introduces names that deserve to be known better. A publication this rich in scholarship could only be produced by a variety of expert scholars; the sixteen contributors are preeminent in their fields and wide-ranging in their knowledge and curiosity. The structure of the volume—essays alternating with shorter texts on individual artworks—permits studies both broad and granular. From the religious to the magical and the poetic to the erotic, encompassing male and female, infancy, youth, and old age, The Renaissance Nude examines in a profound way what it is to be human.

In this book, first published in 2003, categorical algebra is used to build a foundation for the study of geometry, analysis, and algebra.
