Heisenberg

 

Although the Theory of Relativity makes the greatest demands on the ability of abstract thought, still it permits the traditional requirement of Science, as it permits a division of the world into Subject and Object and hence a clear formulation of the Laws of Causality.

This is the very point at which the difficulties of the Quantum Theory begin’.


Elsewhere, on the method of proper observation, Heisenberg writes:

‘What we observe is not Nature in itself but Nature exposed to our method of questioning’.

Hold on to that insight as you read these posts.
