Celestial mechanics and n-body dynamics have been studied by many prominent mathematicians and physicists for centuries. The symposium which brings together mathematicians and physicists in relevant fields has been held every year in Japan since 1967. This year the symposium will be organized by Taiwanese and Japanese researchers, and will take place at the National Center for Theoretical Sciences in Taiwan. The topics concerned with mathematical, physical and computational aspects of celestial mechanics as well as the space mission. The purpose is to provide an opportunity for interaction between people in those fields.
