There have been countless innovations in the realm of science museology after the foundation of the Exploratorium of San Francisco and of the Ontario Science Center of Toronto with, among other things, the introduction of the exhibits hands-on, the use of new technologies and the arrival of virtuality.But most of all a new dialogue was launched, also as a form of transformation of reality. And what is drama but fiction and transformation of reality?This statement is the basis for the belief that museums and the theatre should continue, if not even start, a path to move closer, so as to make their languages work at the service of each other.A dialogical interaction which is difficult (as both languages and their interpreters crave for superiority), strong (the place for communication becomes multi-channel), but necessary (in view of a systemic approach of science communication).It is necessary especially to build an all-encompassing museum to fully play a sociological role of study, interpretation and determination of human society.
