A mobile exhibition, German Science Train, which is organized by the Max Planck Society as part of the Year of Science 2009, takes the public on a research voyage! The idea is to show different aspects of science with an eye to the future. In 12 converted train cars, visitors can dive into different subjects: from cosmology to particle physics, nanotechnology and brain research to applied and industrial research in production, agriculture, energy, environment and mobility. The exhibition is making stops throughout Germany until December. and Luděk Svoboda.
