The interaction between Poincaré and Duchamp while a historical event is also a point of intersection and reference in the universe of human perception. It is the first attempt to represent states which have no statal reality and only exist in time. We have collected images which refer to the intellectual constructs generated by Marcel Duchamp as well as an example of his readymades, "bigboîte" at another site for your discussion in comparison with the magneto-electrical theory of Poincaré.
