Roger Littge's interest and enthusiasm for the Student Experimental Farm translated into this sundial in the garden area near the farm's office. What makes this replica of the ancient solar timepiece special is that "it automatically corrects for the earth's orbital eccentricity and the obliquity of the ecliptic, or tilt of the axis of rotation relative to the orbital plane," says Littge, a postgraduate researcher in the Department of Mechanical and Aeronautical Engineering (photo, right). The sundial was built over four months in 1998, largely by volunteers such as Carol Hillhouse, director of the Children's' Garden Program and ecological garden coordinator. Hillhouse is looking for an area artist to decorate the outside of the sundial with a tile mosaic. The 4-foot-high sundial, made of mortar, steel and wire, is located in the ecological garden directly in front of the Plant Science Teaching Center and the Student Farm Fieldhouse.
