Molecular Workbench 2.0.3

Offers interactive, visual simulations that have been widely used to teach science. As a free, open-source modeling platform, it provides not only a powerful environment for creating interactive simulations (including molecular simulations, mechanical simulations, and quantum dynamics simulations), but also an easy-to-use authoring tool for building user interfaces and writing interactive textbooks.
In addition, it is equipped with a report and assessment system for collecting data and measuring learning with models and simulations. All these functionalities are seamlessly integrated under a simple user interface, which makes the sum of many difficult tasks orders of magnitude easier than they used to be for educators.
