Description:

Professor Millar showed that as we learned more and developed ever more complex and ultimately accurate descriptions of the relative motions of the night sky and our planet and position within the changing models, the celestial sphere model was modified and grew to accommodate more data, but never really left us. Professor Millar came—aptly– full circle in his presentation, beginning and ending with discussion of the celestial sphere in how humankind has interpreted its place within it.
