The Tree of Philosophy

On the way back to Edale from a hill in the Peak District, a tree stands on a slope, and it reminded me of 'The Tree of Philosophy' in Biei, Hokkaido, which I think is one of the most beautiful parts in Japan.

I've been looking for a theme for my assignment and read some papers. I will probably research on the effect of noise reduction by owl wings. All that remains is to obtain permission for that subject.
