I lean towards JP:s view. A good understanding of the model is foremost, and that never seems to end, does it?

As for the rest, I think everyone 'knew' about gravity even if the mathematics describing it was Newtons. Even babies can differ between a normal fall and a fall/curve that is 'wrong'. They've tested this with a white board using magnets and then letting them 'fall' correctly, versus using a magnet behind the board influence the object in front to take a 'wrong' course/curve. The way they measured was by measuring the babies eye movements, and see their movement to the 'right position' for a 'fall', versus the 'wrong' curve/fall that magnetic object in fact did

Wolfekeeper doesn't it ever occurred to you that we really need a different description of something that isn't explainable? You said that if children are taught QM they would simply say yes, but what if QM is wrong? What if there is no double state of Photon, electrons or atoms?

Still it doesn't matter if children say "OK"?

This is exactly what happens to people who go and study QM, even if they don't get it they say "OK", because if Feynman couldn't get it I'm sure others who say "We get it" are either lying or are totally lost. Its also a problem of society if a person is physicist and he/she says QM doesn't make sense than everyone in the Scientific society will attack that person, he/she would be considered dumb and stupid.

Maybe QM is right but scientist aren't even ready to look at other approaches where Quantum duality doesn't have to exist, no one want to risk explaining Photo Electric Effect in wave, because everything underneath will change and has to be change to understand another model.

In the limit of large quantum numbers it will lead to the classical result. Simply put it's solution will agree with the classical for those subjects in which the classical theory is a good enough approximation. Nothing bizarre about it.

Can anyone explain to a layman why the Newtonian view of the world - laws etc.- still work n an everyday level when quantum discoveries/theories show that things work quite differently and sometimes contrarily at the quantum level?

There's an analogy which I like to use. I ask the question "Is this table flat?" and to all of my senses and the best mechanical equipment and optical microscopes tells me that it is. However there are ()in principle) other ways of looking at the surface of a table and that's with a scanning tunneling electron microscope. That is so accurate that what you see on the viewing monitor is a bunch of atoms making the surface bumpy and "seeing a bunch of atoms" has a whole different meaning now.
