I've been covering chemistry software in my last few articles, so this time, I decided to move to physics and introduce a package called JaxoDraw. In physics, there's a powerful technique for visualizing particle interactions at the quantum level. This technique uses something called Feynman diagrams, invented by physicist Richard Feynman. These diagrams help visualize what happens when one or more particles have some kind of interaction.

My last several articles have covered lots of software for doing research in the sciences. But one important area I haven't covered in detail is the resources available for teaching the next generation of computational scientists. To fill this gap, you can use the code provided through the Open Source Physics project.
