The distinction between temperature differences (kelvins) and a point on the kelvin *scale* (e.g. 273.16 kelvins) was taught to me by my first professor in General Physics.
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.
