This lecture by Walter Lewin might not be the latest and might not be the best video quality but the sheer passion of Lewin to explain and teach is quite inspiring.

In the Faculty of Aerospace Engineering, at the TU Delft campus, Lewin shows his audience ways to see and understand rainbows like never before. Enjoy!
