The wonder of teaching through a rainbow

These days my head is taken by a number of research projects that requires solving very technical issues that have to do mostly with numerical computing. Finding the solutions and advance the projects require two things: deep thinking of the best way to implement numerical algorithms that represent the physics I want to investigate and coding them correctly. It is a quite painstaking exercise, which seems very far from the fun of doing physics. So, when the day is over I do really need some physics 101. Here, I found this beautiful lecture on the rainbow by an amazing professor of physics at MIT, Walter Lewin. The rainbow is a spectacular show of nature, but it will look much more spectacular after you watch this performance by Prof. Lewin.
