2Physics Quote:
"The exchange character of identical particles plays an important role in physics. For bosons, such an exchange leaves their quantum state the same, while a single exchange between two fermions gives a minus sign multiplying their wave function. A single exchange between two Abelian anyons gives rise to a phase factor that can be different than 1 or -1, that corresponds to bosons or fermions, respectively. More exotic exchanging character are possible, namely non-Abelian anyons. These particles have their quantum state change more dramatically, when an exchange between them takes place, to a possibly different state." -- Jin-Shi Xu, Kai Sun, Yong-Jian Han, Chuan-Feng Li, Jiannis K. Pachos, Guang-Can Guo

Through Einstein's Eyes

Relativistic ride on a roller coaster &
On a desert road at relativistic speed (0.76 times the speed of light)

If you love relativity and get amazed thinking about all its seemingly wierd
concepts and consequences, you would surely like the following websites of
the Physics department of Australian National University (ANU):

Seeing Relativity :
The Australian National University relativistic visualization project has
used supercomputers to simulate what we might see in a world where the
effects of Einstein's theory of special relativity are everyday experiences.
You can also download two extended relativistic optics videos,
Visualizing Special Relativity, and Seeing Relativity, in RealPlayer format.
A complete printer-friendly commentary is also available for the videos.

Through Einstein's Eyes Online :
You may also visit the Through Einstein's Eyes site to find out about their
latest multimedia work on relativistic visualisation.
