I was lent this journal which has a lot about Goethe's views about science.
Most interesting was his work on colour theory. Apparently he wrote polemics against Newton's views. I was interested to read that one big thing was about the distance of the screen from the prism when projecting a spectrum. That explains a lot of the difficulties I had getting classes to see a proper spectrum over the years. Here's the spectrum from the edge of my mirror. Note that green is missing and it is white down the middle.
I'm also interested in how he managed to get a spectrum of "darkness".
