Temperature of the Cosmic Microwave Background

This discussion offers conjecture about how the CMB temperature of T=2.725 K may be linked to our method of quantifying base units - and the number (e=2.718). The physical basis for this arguments requires that we re-visit how temperature and the Kelvin scale was first defined in the mid-19th-century.) Some of that history can be found at this page: Origins of the Kelvin Scale.
