“This guy is a huuuge nerd” is something you might be thinking after having another article on open courseware just yesterday. You know what? It’s not me being a nerd, but the sheer happiness of seeing such good quality knowledge and wisdom out there for free, is what makes me share this. Yale, as Harvard and MIT, also offers free high-quality courses, and this time so neatly organised that you just want to dig in right then and there. The topic-range is huge, covering music, religion, sociology, technology, languages and lots of other mind-blowingly interesting topics.
