Forever Young (F)

Les fentes de Young désignent une expérience en physique, réalisée pour la première fois par Thomas Young en 1801, consistant à faire passer des photons par deux petits trous percés dans un plan opaque. Sur un écran disposé en face, on observe alors un motif de franges d’interférences propres à la superposition d’ondes.
L’expérience met en évidence la double nature – particule/onde – de la lumière. Elle fut par la suite affinée par la physique quantique.
On observe en effet les mêmes motifs d’interférence lorsqu’on fait l’expérience en faisant passer des éléctrons de n’importe quelle matière à travers un dispositif similaire, et ceci même si on les projette un à un.
La matière, dans sa structure fondamentale résiste donc à la fragmentation et à la représentation d’un monde modélisable propre aux concepts et aux outils scientifiques.
Autrement dit, la réalité est composée d’un tissu de relations qui surpasse en beauté et en complexité notre effort à la mesurer.
