Changing Science

Where does our knowledge come from? What is being researched, and why? With its new permanent exhibition, the TMW invites visitors to embark on a search for clues and reveals how knowledge is created – and how it changes over time.
from 23 April 2026
The natural sciences have fascinated humankind since time immemorial: Groundbreaking discoveries continue to open up new perspectives on the world – from its smallest components to the breathtaking vastness of outer space. Science helps us develop an ever-deeper understanding of what surrounds us and how we live. The new permanent exhibition shows that the path to knowledge is not always linear, tracing how science has changed over the centuries.
 
Methods and tools, world views, society and politics – scientific knowledge is influenced by many factors. These interconnections are explored across nine themed islands: Impressive objects from the TMW collection and interactive stations illustrate not only the paths science has taken from the past to the present, but also how and what knowledge is generated and shared.
 
A wide range of scientific disciplines are highlighted: Visitors can track down particles, discover what quantum physics has to do with philosophy and learn how we measure the world. From astronomy and radioactivity to brain research, the exhibition tells a story that is far from over, placing people and their boundless curiosity at its centre.
 
Changing Science presents the findings of the natural sciences as a dynamic process that has no end and yet always provides new orientation along the way.
