..every time scientists try to observe the quantum world they disturb it. And because at least one quantum of energy must always be involved, there is no way the size of this disturbance can be reduced.

Our acts of observing the universe, our attempts to gather knowledge, are no longer strictly objective because in seeking to know the universe we act to disturb it. Science prides itself on objectivity, but now Nature is telling us we never see a pure, pristine and objective quantum world. In every act of observation the observing subject enters into the cosmos and disturbs it in an irreducible way.

Science is like photographing a series of close ups with your back to the sun. No matter which way you move, your shadow always falls across the scene you photograph. No matter what you do, you can never efface yourself from the photographed scene.
