Define measurement in the Copenhagen interpretation of quantum mechanics.

2. Relevant equations

3. The attempt at a solution

In the Copenhagen interpretation of quantum mechanics, measurement changes the state of a wavefunction, that is, it collapses the wavefunction into one its orthonormal basis vectors (eigenstates). We cannot assume that the system possesses properties if not measured...

I found the second sentence in a book of mine. Problem is I don't know what it means :-)

What do you think it means?
