An excellent answer.
Not what I was expecting, but it certainly
answers the question I asked.

0) David B. exhibited a function that is
continuous but not differentiable and
not particularly physical.

1) The laser temperature is physical but
neither continuous nor differentiable
as we pass through T=infinity.

2) Now, for additional bonus points, exhibit
something that is physical and continuous
but not differentiable.

Cough it up, Joel.
