The Heisenberg Uncertainty Principle

[Parametric]

There is a limit to the precision of pairs of properties of particles such as position and momentum that can be determined.

Does it mean that the properties are non-existent or simply cannot be determined?

Follow-up question: why can't the properties be determined?

[mathematic]

It is not they can't be determined. The principle states there is a limit on the precision.

I suggest you look at the above reference.

I guess I should correct my question: why is there a limit to the precision at which the properties can be determined?

Because these properties are described by waves, not points.

[Enthalpy]

And these waves define the position and moment with some precision, even before humans attempt to make a measure, or other objects modify their behaviour according to this precision.

 

But: what's the difference? Why should you get interested in something you don't observe? Would it make any difference to you?

 

That's not just a joke. It's a very frequent answer by quantum mechanics. Disturbing maybe at the beginning, but reasonable.
