There is so much talk in the news– you can’t escape it- about the many hot new online educational sites.  These  include courses listed by universities (for example Yale and Stanford),  MITx, edX, Udacity, Coursera, and TED lectures. but probably none is hotter Khan Academy, recently partnered with SmartHistory, run by Dr. Steven Zucker and Dr. Beth Harris.   After corresponding with them  on Twitter, I had the good fortune to meet with them this past July and become a contributor for SmartHistory, starting in one of my favorite places in Rome, the Roman Forum (here’s my quick take on the area).  In that setting, beneath some shaded trees beside the Basilica Julia, we chatted about the forum’s history and importance, as well as its layers, describing how what you see in the archaeological site is the summation of several forums, one on top of another, with different chronologies visible simultaneously, often due to modern excavations.  Steven and Beth called our conversation “Digging through Time,” to address why so many of the ancient remains in Rome are located several meters below the modern street surface.  Have a listen, and let me know what you think!   (I certainly look forward to contributing again.)
