Programmers wishing to adopt the Open Source Physics (OSP) library for their own projects are encouraged to do so provided that these projects release their source code under the GNU Open-Source GPL license.

Visit the Open Source Physics website (http://www.opensourcephysics.org/) for ready to use examples of OSP programs.

You can obtain a Plone account on the OSP Developer website if you develop Java programs that use the Open Source Physics library or if you develop curricular material that uses Open Source Physics programs.   Write to Wolfgang Christian ( wochristian@davidson.edu) to request an account.  You can browse this website and download material without obtaining an account.
