| Description: |
- A vertical declining dial approximately 45 x 55 inches. Made of aluminum and brass. Shows the hours from 8 am to 5 pm using analemmas. Analemmas are bounded by the summer and winter solstices and a straight line through them shows the equinox. Daylight time is shown using Roman numerals, with standard time shown in Arabic. In keeping with the motto, a simple equation is written on the dial face, d/dt is not equal 0.
Designer Ronald Bracewell used an oculus, a disk with a central hole, standing 8 cm in front of the dial face. The disk casts a shadow with a bright sunlight dot to indicate both time and season. Hour lines include longitude correction.
This has been relocated; it was previously hanging free below a south facing wall, facing the Terman Engineering Building. Dial is now located on the wall of a covered walkway area.
