The traveling exhibition ‘Power Play‘ explores the theme of energy. It was developed in honour of Julius Robert Mayer born in the city of Heilbronn in 1814. Mayer played a significant role during the establishment of the law of energy conservation, alongside contributors such as James Prescott Joule. This exhibition emphasizes that science is always an „Adventure“. Research is an open-ended process. It includes a process of searching, exploring, and experimenting.
