The Exclusion Principle is laid down purely for the benefit of the electrons themselves, who might be corrupted (and become dragons or demons) if allowed to associate too freely. Alan Turing

Already in my original paper I stressed the circumstance that I was unable to give a logical reason for the exclusion principle or to deduce it from more general assumptions. I had always the feeling, and I still have it today, that this is a deficiency. Wolfgang Pauli

According to Gause ’s " competitive exclusion principle " no two species with identical ecological requirements can coexist in a stable environment. Source: Internet

Additionally, baryons such as protons and neutrons ( subatomic particles composed from three quarks) and some atoms (such as helium-3 ) are fermions, and are therefore subject to the Pauli exclusion principle as well. Source: Internet

Also, as we now know, bosons also have antiparticles, but since bosons do not obey the Pauli exclusion principle (only fermions do), hole theory does not work for them. Source: Internet

Applying the Pauli exclusion principle, this will increase the kinetic energy of the electrons, thereby increasing the pressure. Source: Internet
