During the past few years I’ve taken about 40 MOOCs (Massive Open Online Course) for free and here are two I think would be of interest to EVERYONE.
It’s a two-part global history of the modern world. The professor is Philip Zelikow, currently Professor of History at the University of Virginia and former Counselor to the Secretary of State Condoleza Rice. 
His courses are insightful, digestible, and completely absorbing, unlike any other history course I’ve experienced. And his own personal charm, warmth, and humor add even more.
The Modern World, Part I: Global History from 1760 – 1910
(rated 4.8 out of 5 by users)
The Modern World, Part II: Global History since 1910
(rated 4.5 out of 5 by users)
In each, Zelikow looks at what is happening in different parts of the world at some given moment and shows how they are related. For example, there’s a fascinating connection between the demand for the spice pepper in Europe, the Age of Discovery, the enslavement of South American natives, and ultimately the beginning of the African slave trade.
You don’t have to do any work or take any tests, unless you want to. You can simply enroll, watch online or, if you prefer download Zelikow’s lectures and watch or listen them at your convenience.
I promise it will give you a new understanding of the global interconnectedness that’s ALWAYS been there.
