subject area: Mathematical Physics - Quantum-Relativity (qr)
Quantum Physics; teaching us to count our inverse numbers all over again.
The cypher "i" must always and everywhere be taken to mean "a rotation of" where the numerator that MUST always follow the "i" refers to any number in quadrant units of polarity rotation. In "flat earth arithmetic" (the neo-Pythagorean nonsense that you were indoctrinated into) multiplying a number by one makes no difference, but in Unified Number Theory, leaving out the two ones turns the valid unified number 1.i1 (one times a rotation of one quadrant) into unintelligible gobbledegook; the square-root of a "number" (take away one from nothing) that does not even exist. One can only go so far with nonsense, nonsense can go on making sense for a very long time indeed, until one fine day it suddenly makes no more sense at all.
Unified FNN (flat natural number) is suitable for all work, but is more advanced than is strictly essential for simpler work fields than Quantum-Physics and electro-magnetic wave theory.
Abstract-Set is utter and archaic nonsense and has caused great confusion with work in Quantum-Physics and electromagnetic wave theory. In nearly all simpler work fields, one can "get away with it".

At this trivial magnification, all distant stars should actually be represented by single pixels of light. The absurd astrophysical crowd is always desperate for more funding, as if their work had any value. Leaving this natural feature of the CCD to portray the stars as if they were thousands of times nearer than they actually are, is a deliberate ploy to try and maintain public interest in a subject of which they are in fact sublimely ignorant. For example; despite 60 years of trying very hard with powerful supercomputers, they are no nearer to explaining how any star forms in the first place than they were in 1730. Despite my publication of "Mass Compaction Mechanics" in 2015, nobody was interested. Nobody actually wants to know because not knowing is far more profitable for them than the actual boring routine facts of the matter.
