1.18. SYMFOSIUM QUO VADIMUS: WHERE ARE WE GOlNG?“1
Vancouver, Canada, August 1987 At its General Assembly in Vancouver, Canada, 9-22 August 1987, IUGG will hold a Union Symposium: dedicated to the hundredth anniversary of the birth (in 1887) of the great Dutch geodesist and geophysicist F. A. Vening Meinesz, who was President of IUGG from 1948 to 1951. The title of the Symposium will be “Quo vadimus: Where are we going?” Its aim is to identify themajor key problems of geodesy and geophysics for the next few decades, An encouraging precedent is the famous endeavour of David Hilbert, who in 1900 formulated a set of twenty-three most important mathematical problems “which contemporary science poses and whose solution we expect from the future”. Hilbert’s problems have been highly influential in the subsequent development of mathematics. Today one mans effort may no longer be sufficient to achieve such a goal, especially in highly complex and controversial areas of Earth sciences. Still it is hoped that the success of I-IiIbert’s list of problems may serve as an encouragement of this collective @)Extractfrom the IUGG Chronicle, No. 178 of March 1986.
