Welcome

Simulations of this site are principally related to physics taught in universities for under-graduate students; but some of them can also interest curious peoples with some background. They can be be shown, during lectures,  by the professor, to support demonstrations or illustrateused, and also  by students. Executables , programs which start with a  double click,  are to be downloaded (it’s free) from this site; they  are .jar, that is they are written in Java and require a download into your computer of this language (free from the site of the Oracle Corporation) . It is probably better to have a modern version of Java (Java 7 is the version used here). Quantum mechanics is not used here, except for the tunnel effect and stationary states in potential wells.
Here are simulated the following physical phenomena:


– Optical devices : Michelson- Morley interferometer , Fabry-Perot devices, Young-slits, and also
devices of geometrical optics: diopters , lenses, microscope, Galileo telescope, or the eye.

Professeur d'Université à Paris XI, centre d'Orsay. Spécialité de recherche: la physique expérimentale des particules élémentaires. Après une thèse sur la photoproduction du méson éta, j'ai participé aux expériences sur les anneaux de collision ACO et DCI, puis sur une expérience d'annihilation p-pbar au CERN, enfin à l'epérience H1 à Hambourg. Je tiens à rendre hommage à mes maîtres, aujourd'hui disparus: Jean Pérez-Y-Jorba et Jean-Claude Bizot.
