Today we heard from Don York, professor of astronomy at the University of Chicago, and the founding director of the Sloan Digital Sky Survey. He spoke with us about the history of astronomy, particularly in the optical wavelengths. 

We learned about the anatomy of a telescope, and its development over time.  <br /><br /><a href="http://schoolblogs.cuip.net/nikolaus/wp-content/uploads/sites/11/2013/07/20130716-151508.jpg"><img src="http://schoolblogs.cuip.net/nikolaus/wp-content/uploads/sites/11/2013/07/20130716-151508.jpg" alt="20130716-151508.jpg" class="alignnone size-full" /></a>

The best thing foe me to see was that this "ordinary" man has been able to make such a grand contribution to the field of astronomy. Any of my students, if they wanted to, could apply themselves and make similar contributions.
