I was also taught this in college (early 60's) or maybe even high school. The distinction went out of vogue some time later (70's??). Maybe what Jim saw was someone trying to bring it back.

He used the terms "kelvin degrees" and "degrees kelvin" to make that distinction. There is a need to distinguish "delta T" and "T" in writing if not in formal symbols, I believe. He was not a textbook author. ---- Original message ---- >Date: Wed, 01 Sep 2010 15:05:26 -0500 >From: "James R.
