A fifty year anniversary of a two thousand year dream
Abstract
The planetarium profession started just 50 years ago. At that time, progress in optics, instrumentation, and electricity made possible the real ization of a two thousand year old idea - a perfect representation of the starry sky inside a room. With it came the possibility to have a celestial time machine, with time marked by the motions of the planets.
