I do not find anything to grasp in your spreadsheet paragraph quoted below. What is your point here?
in reply to The world is not object oriented
In order to be able to resolve the problem, especially through a machine, you need a way to (observe and ) describe the entities concerned, and the process to resolve the problem. An ongoing tension in good design is how much you can leave out of the model. For example, look at spreadsheets. Myriads of problems have been effectively solved with spreadsheets (often by people who didn't know that they were programming), even though spreadsheets are innately horrible at really modelling any of the entities which those problems were about.
