Dark energy, the mysterious cause of the accelerating expansion of the universe, is one of the most important fields of research in astrophysics and cosmology today. Introducing the theoretical ideas, observational methods and results, this textbook is ideally suited to graduate courses on dark energy, and will also supplement advanced cosmology courses. Providing a thorough introduction to this exciting field, the textbook covers the cosmological constant, quintessence, k-essence, perfect fluid models, extra-dimensional models, and modified gravity. Observational research is reviewed, from the cosmic microwave background to baryon acoustic oscillations, weak lensing and cluster abundances. Every chapter ends with problems, with full solutions provided, and any calculations are worked through step-by-step.

Within recent years pharmaceuticals have come into focus as contaminants of the environment (see for example Kümmerer, K. editor: Pharmaceuticals in the Environment). At the same time the issue of sustainable chemistry gained momentum. Bringing both together would result in sustainable pharmacy. Sustainable pharmacy is a totally new issue and approach. It addresses environmental, economical and social aspects of pharmacy. In the present stage the focus will be on environmental issues along the whole lifecycle of a pharmaceutical entity. That is dealing with resources and energy input but also with waste issues for example during the synthesis and production of an active pharmaceutical ingredient. Furthermore, it would also look on the compounds themselves and will aim to improve the degradability of the compounds after their use in the environment to reduce the environmental risk caused by pharmaceuticals in the environment. Another issue is the people using pharmaceuticals such as pharmacists, medical doctors and patients. How can they contribute to more efficient use of pharmaceuticals with less environmental burden and less risk for drinking water. The book "Sustainable Pharmacy" will address all these issues and will be the first one dealing with this important topic.

What are meteorites? Where do they come from? Are they a threat? What are they made of? How common are they? As centuries have passed, our knowledge of these extraterrestrial objects has advanced immensely, and today, the scientific study of meteorites provides a wealth of information about the solar system.
Meteorites reveal clues to some of the greatest scientific enigmas:
• the origin of life on Earth
• the mass extinction of species
• the nature and composition of asteroids
• the conditions during the formation of the solar system
• the dust from stars that died long before our Sun formed.
Written by a team of experts, Meteorites is an accessible, comprehensive guide that features over two hundred full-color photographs, diagrams and graphs. Look no further for a wonderful introduction to these powerful, yet mystifying, objects. Brigitte Zanda is Associate Professor at the Mineralogy Laboratory of the Muséum National d'Histoire Naturelle in Paris, and Adjunct Member of the Graduate Faculty at Rutgers University. Following on from her PhD in Geochemistry, she has written many papers in Meteoritics and Planetary Science and other journals, and is a member of the Nomenclature Committee of the Meteoritical Society. Monica Rotaru is Department Chief of Earth Sciences at the Palais de la découverte in Paris, where she organizes scientific exhibitions. After her PhD in geochemistry, she has conducted research in climatology and written television science documentaries.

This is a night by night account of the stars. For every night of the year Sir Patrick Moore gives the reader details of interesting objects that can be seen from earth. It is a book for people with a wide interest in astronomy, those who may not have specialised in a specific area of astronomy and wish to expand their knowledge in all areas.
For this new edition, the text has been brought fully up to date – and the period covered is from 2005 to 2010. Inevitably, this has meant that large sections of the book have been completely rewritten. Much has happened since the first edition was published in 1998.
