science = determinism?

Your arguments are strong, and because I'm not a specialist in QM, I cant
figure out if there is a hole in the assumtions (like the assumtion "we can
messure correctly")

But on the other hand all this is not my point! I don't speak about how the
reality is, I speak about how should we aproach to scientific problems. The
starting point was the psychology, and that also in this scientific region,
it is nessessary to assume determinism. Because:
"Random is that we cant know in advance". If a researcher say at a given
point: I cant know in advance: He say: I cant explain and predict. Theres no
reason anymore for research in that particular field. The way out of this
dilemma is to proof that there cant no determination.
The proofs in QM you've discriped could only be done due to the search for
explainations.
