MOOCs, MOOCs, MOOCs… I love MOOCs or *massive open online courses*. At the moment I’ve been quite aware of Coursera‘s offer but edX.org is also awesome. What a surprise, a course in **Classical Mechanics** by the MIT and taught by Professor **Walter Lewin** has recently started, almost a couple of weeks ago. What a pity, I’m not sure if I will follow the whole course, as I’m already a late with “homework 1” and I won’t be graded if I try to do the exercises, but I think I’ll watch the videos and some readings as a refresher.

I had heard of Prof. Lewin’s original way of explaining Physics and his love for this subject, but this will be my first time in one of his classes. In a short video I’ve just seen he states that *life won’t be the same, I’ll watch the world in a different way after following the course*, so with a promise like this it is an “obligation” for me to follow the course.

Here is the link to the course: MITx: 8.01x Classical Mechanics
