Comet nuclei are the most primitive bodies in the solar system. They have been created far away from the early Sun and their material properties have been altered the least since their formation. Thus, the composition and structure of comet nuclei provide the best information about the chemical and thermodynamic conditions in the nebula from which our solar system formed.
In this volume, cometary experts review a broad spectrum of ideas and conclusions based on in situ measurement of Comet Halley and remote sensing observations of the recent bright Comets Hale-Bopp and...

Schon seit Jahrhunderten investiert der Mensch sein Kapital in werterhaltende Rohstoffe. Ein beliebtes Anlageobjekt war schon von jeher der Wald als Reservoir des nachhaltigen Rohstoffes Holz. In der Vergangenheit waren die Walder eine Domane des Adels. Heute besitzen nicht nur der Staat und v- mogende Privatpersonen Waldgrundstucke, sondern auch Grossanleger wie internationale Konzerne, Banken, Versicherungen, Pensionskassen, Stift- gen von Familien und Universitaten. Die Investoren sehen in der naturlichen Ressource Holz eine attraktive Moglichkeit, um grosse Kapitalmengen la- fristig...

The study of the Solar system, particularly of its newly discovered outer parts, is one of the hottest topics in modern astrophysics with great potential for revealing fundamental clues about the origin of planets and even the emergence of life. The three lecturers of the 35th Saas-Fee Advanced Course, which have been updated and collected in this volume, cover the field from observational, theoretical and numerical perspectives.
