Teaching Feynman Diagrams with Technology

Interesting technological  prosedure for teaching Feynman Diagrams is the following program as you  can see in the video:  

interaction e-e

 the interaction of two photons,

known as pair production γ +γ ➝ e- + e+. (One of

those photons is normally part of a strong static field

that interacts with a high energy passing photon.)                   

the procedure can be seen in the following video:

This procedure is based on the article :

Teaching Electron—Positron—Photon Interactions with Hands-on Feynman Diagrams,  The Physics Teacher -- April 2013 -- Volume 51, Issue 4, pp. 232, George Kontokostas and George Kalkanis.

and also based on the greek presentation :Ψηφιακές Αναπαραστάσεις και Τεχνικές για την Εκπαιδευτική Αξιοποίηση των Διαγραμμάτων Feynman, Bόλος 2013.
