Heisenberg says that no events can be described with certainty because a principle of uncertainty or of tolerance is inherently a part of the way the units of the world fit together. One achievement of physics in the twentieth century has been to prove that that aim is unattainable. . . . What physics has now done is to show that . . . And those who claim it, whether they are scientists or dogmatists, open the door to tragedy.
All information is imperfect.
We have to treat it with humility. I mean that literally. . . I remember a phrase that Max Born used. . . Max Born meant that the new ideas in physics amount to a different view of reality. The world is not a fixed, solid array of objects, out there, for it cannot be fully separated from our perception of it.
