The document recounts the history of the granite gnomon, known as the sun ball, originally part of a sundial donated to Columbia University in 1914. After developing a crack, the sun ball was removed in 1946 and believed to be destroyed, but it was later discovered to have been kept in a Michigan field. A student, Steve Pulimood, is working to restore the sundial and bring back the sun ball, highlighting its historical significance and the evolving purpose of the sundial's base on Columbia's campus.
