New permanent exhibition: in search of knowledge

The natural sciences fascinate, divide opinion and constantly offer new perspectives on our world. But the path to knowledge is not always straightforward, as ‘Science Changes’, the new permanent exhibition at the TMW, demonstrates.
“Science Changes” sets out on a journey of discovery, bringing key scientific breakthroughs – from astronomy and earth sciences to quantum physics – to life across 800 m². Visitors learn about the often winding paths these discoveries take from initial observation to full understanding.
 
Highlights from the TMW’s extensive collection, such as the 16th-century Immser clock, which visualises the movements of the planets, are juxtaposed with state-of-the-art research environments such as a quantum optics laboratory. The diverse objects on display reveal what influences scientific understanding:
for alongside methodology and tools, worldviews, society and politics are also key factors in the generation of knowledge.
 
The permanent exhibition “Science Changes” focuses on humanity and its boundless curiosity, demonstrating that the acquisition of scientific knowledge is a dynamic process that is never fully complete, yet constantly provides new direction.
