A consistent pursuit of classical physics forces a transformation in the very heart of that physics.

Thus, the more precisely the position is determined, the less precisely the momentum is known, and conversely.

It will never be possible by pure reason to arrive at some absolute truth.

Natural science, does not simply describe and explain nature; it is part of the interplay between nature and ourselves

The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory can give us an indication of the probability that the alpha-particle will leave the nucleus in unit time, but it cannot predict at what precise point in time the emission will occur, for this is uncertain in principle.

Science clears the fields on which technology can build.

Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.
