Zitterbewegung
>From Wikipedia, the free encyclopedia.
Zitterbewegung (English: "jitter") is a theoretical helical or circular motion of elementary particles, in particular electrons <http://mailman.lbo-talk.org/wiki/Electron> , which is responsible for producing their spin <http://mailman.lbo-talk.org/wiki/Spin_%28physics%29> and magnetic moment <http://mailman.lbo-talk.org/wiki/Magnetic_moment> . The existence of such motion was first proposed by Erwin Schrödinger <http://mailman.lbo-talk.org/wiki/Erwin_Schr%C3%B6dinger> in 1930 <http://mailman.lbo-talk.org/wiki/1930> as a result of his analysis of the wave packet <http://mailman.lbo-talk.org/wiki/Wave_packet> solutions of the Dirac equation <http://mailman.lbo-talk.org/wiki/Dirac_equation> for relativistic <http://mailman.lbo-talk.org/wiki/Relativistic> electrons in free space, in which an interference between positive and negative energy states produces what appears to be a fluctuation (at the speed of light) of the position of an electron around the median. Predicted frequency of zitterbewegung is about 1021Hz.

charles:
do a google on "Zitterbewegung", doesnt relate to relativity theory, but you'll find the description interesting.
