Terra Data – Our Lives in the Digital Era

Generated by sensors that digitize the real world, the volumes of data now in circulation are growing exponentially. Processed by computer algorithms, that data has the potential to improve our decision making and enable us to better anticipate events. But do we know what data is? 

Through a series of hands on exhibits, visitors at the Cité can explore the world of data, how algorithms help us turning it into knowledge, and its impact on our lives. 

During the development of the exhibition, the Cité’s exhibition team worked with a group of 70 volunteers to capture their thoughts on what data means for our society.  The process was filmed and the video is showed at the end of the exhibition.

Terra Data is open until 7 January 2018 at the Cité des Sciences et de l'Industrie.




The city of Paris boasts two prestigious centres promoting science and technology, the Cité des sciences et de l’industrie and the Palais de la Découverte. From January 1st, 2010, they have joined forces to create a new institution: Universcience placed under the joint responsibility of the Ministry for Higher Education, Research and Innovation and the Ministry for Culture. With almost 3.5 million visitors each year (3 million at the Cité des sciences et de l’industrie and 550 000 at the Palais de la découverte), Universcience is the fourth most popular cultural establishment in Paris after the Louvre, Versailles and the Georges-Pompidou Centre.
