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.
