THE FIRST LAW OF THERMODYNAMICS
This paper discusses the First Law
of Thermodynamics in the context of its alternative expression as the Principle
of Conservation of Energy. The author wrote this paper in order to emphasize the
scope for energy transfer as between the medium of background space, the aether,
and matter and introduced the notion that the local aether has a temperature
that we sense as the 3K cosmic background temperature.
