Heisenberg solved for the quantum behavior by two different methods.
Although these media are very different, their behavior is very similar as they all show macroscopic quantum behavior.
The Bell violations show that no resolution of such issues can avoid the ultimate strangeness of quantum behavior.
In the last couple of years, however, researchers have started working with mechanical oscillators that can display quantum behavior in some circumstances.
Molecular geometry is determined by the quantum mechanical behavior of the electrons.
The process explains why we tend not to observe quantum behaviour in everyday macroscopic objects.
This isn't the first paper to describe quantum behavior in a mechanical device, but it seems to be one of the cleanest.
It was refinements to the 2001 experimental technique that extended the time the particles maintain quantum collective behavior.
That was before quantum behavior came to be better understood by Werner Heisenberg and those who followed.
Will 21st century technology reveal quantum behavior in the realm of human-size objects?
