### Re: [Fis] Probability Amplitudes and philosophical basis of QM

Dear Lars-Göran and colleagues, I think that probability amplitudes should have a single meaning as well as any concept that our mind can invent. Heisenberg said in his Lectures 1955-1956 ”Physics and Philosophy”: “Descartes realizes that what we know about our mind is more certain than what we

### Re: [Fis] Probability Amplitudes

Dear Hans, Thank you for your explanation about probability amplitudes, that clarifies a lot. My only worry was about the *epistemological* implications of quantum mechanics in its standard formulation, that in my opinion point to a paradigm shift, which is felt not only in this domain, but in
