Introduction

A visit to the exhibition starts with a countdown. Visitors approach the exhibition area on the escalator to the accompaniment of a voice counting down from ten to zero. Once inside the exhibition, the mood is set with the HDTV video "Zahlen in Bewegung" (“Numbers on the move”). This shows how omnipresent varying numbers are in our daily lives.
