The sciences have always provided a fount of inspiration for artists. "Say it isn't so" traces this phenomenon and shows that contemporary art is by no means increasingly converging with science, but is rather standing beside it with a coolly appraising eye. Special guests include Marcel Duchamp, Nikolaus Lang, and Bruce Nauman.

"Color in Flux" examines how artists have deployed free-flowing color. The works of leading Abstract Expressionist and color-field painters are combined with more contemporary works: among those included are Ai Weiwei, John Baldessari, Willi Baumeister, Lynda Benglis, Katharina Grosse, Kitty Kraus, Joseph Marioni, Bernhard Martin, Paul McCarthy, Sigmar Polke, Jackson Pollock, Gerhard Richter, Dieter Roth, Thomas Ruff and Oskar Schlemmer.
