## The Acronyms of Operational Physics (OpPhys)

### Operational Physics (OpPhys)

Infinity inre Operational Physics is defined as having no spatial, temporal or physical limits. Whatever is described as infinite has no spatial, temporal or physical limits.

Finity (humorous opposite of infinity) inre Operational Physics is defined as having spatial, temporal or physical limits. Whatever is finite has physical and/or mathematical limits.

-> means is related to, moves towards, goes forwards
<- means moves backwards
<-> means is related to, or the convertibility of (m<->e as in m = e/c2 and e = mc2 = matter can be converted into energy/energy can be converted into matter)

n= means not equal (used when there is a possibility that a font may not translate ≠ [Option + =] as the symbol which means "not equal" or "is not equal to", as in the Laws of Logic wherein A = A but A n= B and A n= A + B)

### The Laws of Logic (which also apply to Physics)

(1) A = A means a thing, A, can only equal/be itself.
(2) A n= B (A ≠ B)  means A is not equal to and therefore cannot be B.
(3) A n= A + B (A ≠ B) means A is not equal to both A and B.
