A Comparison of the Dynamical Evolution of Planetary Systems: Proceedings of the Sixth Alexander von Humboldt Colloquium on Celestial Mechanics Bad Hofgastein (Austria), 21-27 March 2004
Bad Hofgastein who made the very successful Salzburger Abend with indi- nous music from Salzburg possible. Special thanks also to the former director of the Institute of Astronomy in Vienna, Prof. Paul Jackson for his generous private donation. We should not forget our hosts Mr. and Mrs. Winkler and their employees from the hotel who made the stay quite enjoyable. None of us will forget the very last evening, when the staff of kitchen under the le- ership of the cook himself came to offer us as farewell the famous Salzburger Nockerln, a traditional Austrian dessert. Everyone got a lot of scienti?c input during the lectures and the discussions and, to summarize, we all had a spl- did week in Salzburg in the Hotel Winkler. We all hope to come again in 2008 to discuss new results and new perspectives on a high level scienti?c standard in the Gasteinertal.

Expeditions of German scientist Baron Friedrich Heinrich Alexander von Humboldt to Latin America from 1799 to 1804 and to Siberia in 1829 greatly advanced the fields of ecology, geology, and meteorology.
Friedrich Wilhelm Heinrich Alexander Freiherr von Humboldt, a naturalist and the younger brother of the Prussian minister, philosopher, and linguist, Wilhelm von Humboldt, explored. Quantitative botanical work of Humboldt founded biogeography.
Humboldt traveled extensively, explored, and described for the first time in a generally considered modern manner and point of view. He wrote up his description of the journey and published an enormous set of volumes over 21 years. He first proposed that forces once joined South America and Africa, the lands, bordering the Atlantic Ocean. Later, his five-volume work, Kosmos (1845), attempted to unify the various branches of knowledge. Humboldt supported, included, and worked with Joseph-Louis Gay-Lussac, Justus von Liebig, Louis Agassiz, and Matthew Fontaine Maury and most notably conducted much of his exploration with Aimé Bonpland.
