Hello!
If you're planning to take Concepts of Math (21-127) in Spring 2014, we'll be using Blackboard, and I don't plan to maintain a separate course webpage.
If you took Concepts of Math (21-127) in Spring of 2013 and wanted to see the course webpage, it has a new address, for the time being. (Most of this page is irrelevant to students taking it in Spring 2014, as we've changed textbooks.)
If none of these applies to you, then you might actually be looking for Mike Picollelli's personal webpage.
