Question:<br>
</font><font face=3D"Lucida Grande" size=3D"+0" style=3D"font-size:13=
pt;color:#000000;">I am an intruder from the Chemistry page in bad ne=
ed of your expertise. The doubts are related to the fermionic states,=
the school's term is beginning in a fortnight and I would like to be=
ready for my students questions:<br>
a) Can bosons break Pauli's exclusion principle??? How do you explain=
this please??<br>
b) Can somebody briefly explain how is it that paired fermions may be=
have as bosons?? Is it because of the spin number???Does it mean that=
they can go from not being able to break Pauli's principle to be abl=
e to do so??<br>
