1. Simulation with Open Source Physics Butch DeBerry Advisor: Dr. Bruce Mason

2. Outline Motivation The Open-Source Software Model Open Source Physics Our project Conclusion

3. Motivation Assist in the instruction of QM Improve the quality of understanding Make a lasting contribution to the physics education community

4. The Open-Source Software Model Development distributed among many submitters Project manager sets milestones and packages releases Users have access to source code –Improvements and adaptations are encouraged –Users are encouraged to submit their changes

5. Open Source Physics Software library with applications –Physical simulation –Numerical analysis –Graphical interface Library is relatively closed –Development centralized –Only release packages available Applications are open all the way –This is what we’re working on http://www.opensourcephysics.org

6. Our Project QM probability distribution visualizer –Display 3D graphical representation of quantum probability distribution Example: 3D Spin –Improvement over current software Only shows expectation value in 3D –Requires extensive 3D graphics tools and knowledge

7. Conclusion Goal: Write an application using Open Source Physics library to display 3D probability distribution OSP’s 3D graphics library is incomplete –Contribute to OSP library Makes our work available for others Developers are not favorable to outside contribution –Develop our own This is what I’ll probably do –Wait for OSP developers Wouldn’t make for much of a Capstone
