The Arithmetic and Logic of Nature.
The arithmetic of our Universe is exponential. Nature bears almost no connection with the over-simplistic neo-Pythagorean flat-earth-arithmetic taught in our university's utterly irrelevant departments of so-called "mathematics".
Unified FNN 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 will cause great confusion with any 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.
