| Description: |
- This vertical dial is set on an 11-foot (3.4m) stand very near the front wall of the Museum. The 18-inch (46cm) dial face is eye-catching with a portrait of Albert Einstein hand engraved into stainless steel. The Equation of Time curve is used symbolically as a wave of light that in dual nature becomes a particle to create the photoelectric effect. This is not a functioning sundial even though the gnomon is set to its latitude in Oak Ridge. Created as a south facing dial, it sits facing nearly due west. The hour numbers from 6am to 6pm were uniformly placed, "with the idea that they coordinate with the gnomon and axis of the earth." They do not represent the proper hour spacing for a vertical dial, being more appropriate for an equatorial sundial..
