Developed by physicist Frank Oppenheimer and opened in 1969, this innovative and interactive museum behind the Palace of Fine Arts is dedicated to art, science and human perception. The hands-on displays unveil the mysteries of science and language. The exhibits present theories simply and succinctly. For a different kind of hands-on experience, check out the tactile dome, a labyrinth of different textures that explorers negotiate in the dark. Seminars on quirky subjects are offered on weekends
