In hmolscience, powered CHNOPS+20E is the scientific model or definition, aka the Swan-Thone-Thims definition, of human as a "powered" CHNOPS plus (+) twenty element (20E) species, the twenty elements (20E) referred to here being the elements of the 26-element human molecular formula, less the six CHNOPS elements.
In 1936, Frank Thone defined plants, animals, and humans as “evolved CHNOPS plus substances”.
In 1974, Henry Swan, indirectly, redefined biochemistry as the study of powered H20-based CHNOPS systems, or hypothetical extraterrestrial life forms, the study of powered H2S-based or NH3-based CHNOPS systems; the key takeaway point here being that his definition usurps “bio” with “powered”, which he defines as the “energizing of electrons by photons” from a star.
In 2015 to 2018, Libb Thims, in various publications, building on Ostwald, Thone, and Swan, began to employ the phrase “powered CHNOPS+20” [molecule, phase, thing, element existive]; and in 2020, began to adopt the term “powered CHNOPS+20E”, the letter “E” being short for element, “20E” being short for the 20 elements, in addition to CHNOPS, that humans are comprised of, by functional mass (see: human molecular formula).
- Note: the key importance of this definition is (a) the shorthand notation of "+20E", which condenses the description of twenty elements, into four symbols, and (b) the use of the adjective "powered" obviates the need to refer to a virus, bacteria, plant, animal, or human as a "living" thing; hence solving the defunct theory of life debate, and reconciling the life does not exist (or abioism) view.
