It was actually a (somewhat?) serious question on several grounds.
Can I get reflections from a lumped circuit model of a transmission line made
out of just Rs and Cs? If so, I can probably do the same in the thermal
world.
Can I get reflections in a thermal context? Bruce's URLs say yes, but my
math is rusty enough that I can't quickly understand what's going on.
If a thermal problem can generate reflections, does that mean it also has
something corresponding to inductance? If so, what is it?
It's possible that the key idea is time-delay. In the electrical world, a
delay is a transmission line which has both C and L. I'm not sure what the
one-dimensional equivalent in the thermal world is.
What's the speed-of-light equivalent in the thermal world?
