The Experiment at the Esplanade of the Malek Haddad Cultural Center Eleven groups from different parts of the Constantine Wilaya made the measurements...
It started with a Workshop/Conference at the Malek Haddad Auditorium. Then the various participants scattered to form teams throughout the esplanade of the Center as the Sun was playing a catching game with the clouds. In the background, the Emir Abdelkader Mosque and University.
