I don't look down at my feet.
As I walk, I look at the scenery and be enthralled by the fresh air and the scenic ambiance. I look ahead the street and I would be awed by the distance, by the magnificence of the world. I look at leaves, and even these simple organic compounds can have an aesthetic aspect.
Everything is under mathematics and science, but nature is not. To fully connect with nature, we would have to put our pure maths and science aside.
