Although at first glance the left side of this picture may look like a it is a mirror image of the right side, it isn't, quite.  See how many deviations from perfect mirror symmetry you can find.

This image conjures up what might come to mind when you hear the term "B Factory", which is used to describe the accelerator system that creates the millions of B mesons that must be generated in order to study CP violation in their decays.  The 3x3 matrix of "V's" represents the CKM matrix, which quantifies some of the weak interactions between quarks.  According to the Standard Model the nine elements of the CKM matrix are interrelated closely in very specific ways, a premise that can be tested by the B Factory experiments.
