Simulation with Open Source Physics

Advisor: Dr. Bruce Mason
Outline• Motivation
• The Open-Source Software Model
• Open Source Physics
• Our project
• Conclusion
Motivation• Assist in the instruction of QM
• Improve the quality of understanding
• Make a lasting contribution to the physics education community
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
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
onhttp://www.opensourcephysics.org
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
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
