The tiles in Antin Square, which is located at the entrance to Tel Aviv University, include covertions and comments by scientists and other intellectuals.
The current tile presents Heisenbergs uncertainty principle, which says that it is not possible to simultaneously determine exact values for pairs of variables and is one of the fundamental principles of quantum mechanics.
Three months earlier, the tiles were photographed in the same square. During the photograph, it was discovered that a number of tiles had been removed and replaced by other tiles. The current tile replaced another tile
