QUANTUM IN-SEPARABILITY
 

In-separability, still called the EPR effect (standing for Einstein Podolski Rosen), is a quantum phenomena which runs counter to common sense. Although the reality of this phenomena  has been solidly established experimentally (notably by the french team of Alain Aspect in 1983), its consequences remain obscure. Inseparability brings into question the idea of  localisation of objects, which seems to be self evident. Let's explain:

Let's imagine two particles which interact then distance themselves one from the other: These two twinned particles are said to be correlated, like for example two photons emitted by the same excited atom.
These two photons, like all photons, are endowed with a particular property, polarisation, which is defined as the direction of the electric field with which they are associated:
Two correlated photons would thus have a polarisation of +1 for one and obligatorily of -1 for the other.

The experiments of Alain Aspect in 1983 came down cleanly in favour of the quantum interpretation. This has revolutionary consequences upon our vision of the world:




The interpretation of in-separability is very fine and delicate for the moment and the most crazy hypotheses have been put forward by physicists:

To illustrate this EPR effect, let's quote Etienne Klein who is a physicist at the CEA and teacher at the Ecole Centrale. 
Here he imagines using romanticism as a theoretical foundation. 

Two hearts which have interacted in the past cannot be considered in the same manner as if they had never met. Marked forever by their encounter, they form one, wholly inseparable.


 

Conclusion
 

Quantum physics raises questions of a philosophical order, which are far from being elucidated.
They concern notably the relationship between physical objects and their representation. Can we ever come to understand a truly objective reality or don't we have access to anything other than appearances?
The least that we can say, is that quantum physics doesn't give us a clear vision of what we call the "truth" (see quantum inseparability).
It does not permit us to associate physical objects with simple images. For example, we cannot give the atom a design which is truly faithfull. Fortunately, all that does not prevent quantum physics ending up with some extremely concrete realisations, as with the electron microscope or with the laser.
 

crazyflash: The TIC Camp Song
Particles live reclusively in the surrealist camp TIC : 
  • The camp was built by a german Plancke called Max in 1900.
  • It's there that we cast some light on a mysterious animal which only lives in the waves: the photon
  • The aggressive photon sees red when it is cast out by its excited master, the electron. When it is blue it becomes highly energetic. In an instant though, the photon passes away to rejoin the kingdom of the spectres.
  • The master of the photon, the electron, is a hermit living in a mysterious resort called Orbital. It is impossible to see it without it getting diverted along the way, so if you do see it, ask it about to tell you the principal behind its indeterminacy (a discource that few of even the initiated understand anyway!).
  • One of the chiefs of the Camp called Mr Pauli, has divided particles into two groups based on their behaviour:
  • BOSONS, very gregarious and sociable, have a very good capacity as mediators and adore managing the relationships between forces.
  • FERMIONS, very individualistic, they exclude each other and are very materialistic. To punish them, Mr Pauli has only given them half spins.
  • This reclusive life favourises the correlations between particles: pairs form and rapidly become inseparable. A curious spiritualistic connection then becomes established between particles, which is one of the most disconcerting aspects of camp TIC.
