Please visit Special Collections for our latest exhibit, “Shapes in Books: Triangles, Circles, Squares.” It features, not surprisingly, rare books on geometry, but also evocations of the occult (as in the fiery triangle-square-circle engraving from Khunrath’s alchemical masterwork of 1595), typographic renderings of Pascal’s triangle, practical and artistic uses of graph paper, and an illustration of an early motorcycle — all to get the wheels in your brain turning on the subject of shape.
