Whaaaat? Where is that coming from????

For homework, come up with five different lines
of solid physical evidence supporting the exclusion
principle.

I'll give you the first one for free: Do you
think the chemical properties of helium are
different from hydrogen? I think they are
different as a matter of fact, not because
"some guy said so". In the absence of the
exclusion principle, atomic theory would
predict them to be not much different.

That's all true, but unnecessarily complicated.
And it leaves the door open to the next-level
question: if the exclusion principle is derived
from the spin/statistics theorem, we have to ask
what is the evidence supporting the spin/statistics
theorem.
