John Denker has certainly changed my mind about the inaccessibility
of an explanation of the rainbow without mathematical background.
Nothing could do that better than a concrete example, and this
certainly is an excellent example of what can be done educationally
with a computer that can't be done by traditional methods. I think
that quite a bit more support text is needed to make this a complete
lesson, but the difficult part is done. Hooray for Fu-Kwun Hwang! I
hope he was not upset in the earthquake.
