For the reopening of the Palais de Tokyo, Laurent Derobert has dreamt up a constellation linking several cupolas in the building. At the main entrance, visitors are confronted by the mathematical formula for “Force d’attraction de l’être rêvé” [Power of attraction of the dreamt-of being]. On the lower floor, “Vitesse de libération de l’être” [Speed of liberation of the being] and “Asymptote des mondes” [The worlds’ asymptote] are opposite one another. In a more secret area, the formula “Dérivée du souffle” [Derivative of breath] can be glimpsed. From these four crucial formulas, the artist thus sketches a pursuit of sublimated beings and worlds.
