Positron-electron annihilation

Demonstrates the annihilation of position-electron pairs. Emphasizes the conservation of energy and transformation of matter in radiation, pointing out that only a small amount of matter is transformed in the process, whereas in the annihilation processes, the total rest energy of a position-electron pair is converted into the energy of photons.
