A Geoscientist's life

Koen Weber, professor in production geology at the Technical University, Delft, retired at the end of last year. To mark the occasion and honour his career both as an academic since 1984 and previously as a distinguished research engineer with Shell, a symposium on production geology was held in Delft. The seminar included contributions from a number of present and past colleagues and former students. We publish here Professor Weber's own farewell address entitled 'Adventures in Soft Science', one man's view of where the geosciences have reached at the beginning of the new millennium enriched by the experiences of a lifetime.
