The exhibition does it through over 40 interactive experiments: the section “Phenomena … and marvels” proposes a sequence of spectacular experiments that illustrate the hidden mechanisms of physical phenomena involving energy. Phenomena at times surprisingly simple, at others complex, but always capable of entertainingly explaining the history of Man's knowledge of Nature. The section “Systems … and problems” explores energy transformations in complex systems, from the tiny cell to the large city, with the aim of explaining the problems connected to the unsustainable exploitation of our energy resources, and how a rational use of energy could improve the health conditions of our planet and of all of its inhabitants
