"Serving the Universe on a Paper Plate"

Activity: Feynman Diagrams

Demonstrate an application of Feynman Diagrams in which a particle collides with an anti-particle.

	On one plate draw a possible circumstance and the resulting decay, as shown. For background information on Richard Feynman's method, see http://www2.slac.stanford.edu/vvc/theory/feynman.html.

	Make a slit across the top of a second plate.

	Slide the slit of the second plate over the first plate in the direction of time (+t) to illustrate what the observer sees.
