That's good news.  Glad we agree.

Will look into it later.  But yes,  I'm sure there's definitely three
State Level (class level), Operational Level (functional level) and
State-Change Level (computational physics level)

UML is a general language used for data and process modelling.  When I
first learned it I was quite interested, because it seemed relevent to
my interests (ontology and knowledge representation).  But only after
a grest deal of exposure to UML did it dawn on me that it *is* the
secret to the entire universe :D  Seriously, many of the concepts I
have been intuitively groping towards had actually already been
developed for me via UML and I was highly bemused that I could simply
quickly fit all my ideas to UML concepts!

You may be skeptical, but I think that OOP (Object Oriented
Programming) and UML is definitely the correct paradigm over all other
approaches.  Indeed they had their roots in the attempts to model
reality (via simulations).  I think UML is far more profound than
everyone realizes and could form the basis for a TOE (Theory Of
Everything).  *If* we regard everything as 'Knowledge' (*not* mere
'information' but 'knowledge') *then* from *this perspective* general
DP modelling tools can be used a language for understanding

The three levels of reality (and hence three levels of time or
cauaslity) implied by UML are so blindingly glaringly screamingly
obvious that it's amazing that no-one but me appears to have noticed
them ;)
