| Description: |
- With a bit of whimsy at the end of each day for over two years, Dr. James Griffith marked the position of a ray of sunlight on a wall that entered from a west window overlooking the Potomac river. The result is an analemma, tracing the sun's position at 4:10 pm E.S.T. throughout the seasons. Dr. Griffith was a chemist, but as written on a plaque next to the analemma, "Exactly what this has to do with chemistry per se is not perfectly clear, but Viva Principia Scientifica!"
