Developed by Manuel Joffre, Jean-Louis Basdevant, and Jean Dalibard at France's Ecole Polytechnique, this Web site covers topics in introductory quantum mechanics through a series of animations and simulations. Topics covered include Wave Mechanics, Quantization in one and three dimensions, Quantum Superposition in one and two dimensions, and Spin 1/2. Students will find these difficult concepts easily and intuitively illustrated. Most of the simulations are interactive, allowing visitors to change the parameters in order to better grasp the concepts.
