The third Part Of The 4th Session Of Course 20

In general, heat may be transferred in three basic genre of manners:  Heat may be transferred by either radiation, and/or by convection, and/or by conduction.  So, in one general case, heat may be introduced into a given arbitrary area or region, simply by the implementation of an opening -- by which there may then be more of a viable scalar amplitude of a heat differential to thence be produced -- to where one may take a slant, as to this potentially being a case of either a condition of radiation, and/or of a condition of convection, and/or of a condition of conduction.  Heat may also be introduced into a given arbitrary area or region, via the resultant effects of the shining of any directly corresponding black body source (a black body, in physics, is an entity that absorbs and/or radiates a lot of heat), that is to thereby to then behave in so as to radiate infrared energy into the so-stated generally speaking given arbitrary area or region.  Heat may be transferred into a region, as well, by a chemical means of either a plasma and/or of a molecular-based differential -- to where this may then be considered as a general case of the transference of heat by the means of convection.  And heat may be transferred into a given arbitrary area or region, by a valence charge differential, -- to where this may then to be considered as the general example of the case, as to heat being transferred via the general means of conduction.  All temperature changes are related, in some manner or another, to a transfer of some sort of heat differential-based perturbation of the infrared energy that is proximal to a certain general locus of an area or region.  Heat is an actual general phenomenology.  "Cold" is NOT an actual phenomenology. (Back to basics).  What "cold" is, is a relatively low scalar amplitude of heat.  I will continue with the suspense later!  To Be Continued!  Sincerely, Samuel David Roach.
