Drawing Feynman Diagrams for Fun and Profit with JaxoDraw

摘要

I’ve been covering chemistry software in my last few articles, so this time,rnI decided to move to physics and introduce a package called JaxoDraw. Inrnphysics, there’s a powerful technique for visualizing particle interactions atrnthe quantum level. This technique uses something called Feynman diagrams,rninvented by physicist Richard Feynman. These diagrams help visualize whatrnhappens when one or more particles have some kind of interaction. I say onernor more because a single particle could spontaneously kick out other particle/rnanti-particle pairs and then swallow them back up again. Needless to say,rnquantum physics is weird.
