In acronyms, PCN (LH:7) is short for “physico-chemically neutral”.


The following table, which gives a quick etymological overview of each letter: P, C, and N, and shows the basics of how each letter refer to "first principles", as devised in the Thales (570BC), who held that the first principle was "water", to Aristotle (350BC), who amassed all views into one, era of Greek philosophy:

Letter Egyptian Greek principle Greek Letter Symbol Affix Science
P Ptah Fire Phi Φ, φ physico- Physics
C Keme (Χημ) Earth -chemically Chemistry
N Nun Void (or vacuum) (water / darkness) (nothing) Nu Ν, ν neutral No bias

In other words, PCN-terms are "first principle neutral", i.e. unbiased with respect to anthropism-bias or so-called "first person bias", or personal bias.


In 2012, Libb Thims, in the JHT submission, editing, and open peer review[1] process, Thims enacted so-called "terminology reform protocols"[2] for author submissions.[3]

In 2015, following the absorption of the "physico-chemical" sociology work of Beg, Thims began to employ the term "physico-chemically neutral".

In 2016, Thims, in his "Lotka’s Jabberwock: On the ‘Bio’ of BioPhysical Economics" talk, employed the term "physico-chemically neutral".[4]

In 66AE, Thims, having employed the term "physico-chemically neutral" so frequently, introduced the PCN acronym, e.g. PCN-terms, PCN-view, etc., for the hyperlink and and writing function of quickness.
