Dear Tony,

By the Pauli Effect, I presume you mean the Pauli Exclusion Principle.
This effect applies to all particles known as Fermions which have half
integer spin. The most common examples of Fermions are electrons,
protons and neutrons, which make up matter. The Pauli exclusion
principle states that no two Fermions can be in the same state.  For
example if an electron is in an orbit around an atom then a second electron
must be in a different orbit.  This principle has a tremendous effect
on the structure of matter since the states of electrons determines the
properties of atoms and molecules.  In particular the exclusion of
electrons from occupying the same orbit is what leads to the periodic
properties of the elements.

There is also something called the Pauli Effect, which is a joke about
Wolfgang Pauli being bad luck.  For more information on that you might
want to check out
