Elementa 1 demonstrates groundbreaking findings in natural sciences and technology from the beginning of the Industrial Revolution. Visitors can perform their own experiments. For example, turning a piece of wood using a pole lathe, or building a bridge following considerations by Leonardo da Vinci to find out what makes an arched bridge so stable and how this knowledge is still deployed in producing folded boxes and other items . The subject matter ranges from optics to mechanics and computation. Precursors of today´s computers such as the abacus and Napier’s bones and original instruments from the Mannheim Observatory of 1774 bring visitors back to the period before 1800.
