computer applications we partially copied some
solutions that evolved in human society network.
 
I had produced software for some time and know the concepts of oop.
I actually use these ideas occasionally, because they make sense.
E.g. I make a diffence between a text, a symbol, a name and an object.
Example:
E= m c²
  is a famous equation, but at the beginning only a short text.
This text is interpreted as equation and became by this a symbol for some sort of relation in physics.
The symbol 'E' is also a short text, but interpreted as 'energy'.
The term 'energy' is a short text again and not energetic itself.
Meant is a certain physical quantity, which occurs in a certain context and has the dimension 'energy' and a numerical value in e.g. Joules.
That measure is an attribute and belongs to something, which is called 'object'.
In phyiscis I prefer the term 'system' instead of 'object'.
Systems are something of interest, which is under consideration.
Systems consist of systems, which also contain systems.
The borders of systems are arbitrary and infinetely thin.
The borders are, what we observe.
Now this system under consideration has something as an attribute, which we can call 'energy', which is measured in Joules and symbolized by 'E' in an equation.
