Natural science, does not simply describe and explain nature it is part of the interplay between nature and ourselves. – Werner Heisenberg
What we observe is not nature itself, but nature exposed to our method of questioning. – Werner Heisenberg
The violent reaction on the recent development of modern physics can only be understood when one realises that here the foundations of physics have started moving and that this motion has caused the feeling that the ground would be cut from science. – Werner Heisenberg
Nature is sanative, refining, elevating. How cunningly she hides every wrinkle of her inconceivable antiquity under roses, and violets, and morning dew! Every inch of the mountains is scarred by unimaginable convulsions, yet the new day is purple with the bloom of youth and love. – Ralph Waldo Emerson, “Progress of Culture”
