I was going to continue the DQ, DW discussion with the following observation
that early writers often write the first law as:

DQ = dU +DW  (see Martin Bailyn's "A survey of Thermodynamics", pg 63)

and I was going to express the idea that perhaps this is a better way to
view matters, particularly with respect to how one should partition the
energy inputs to the system of interest.
