Yeah, I pretty much agree with most of your points. Although, I don't think you should read the four points quite as standalone as you appear to have done: it seems more a train of thought to the last one, but in a rough way, not a proof way.

Objects are fairly good at modelling discrete systems. They're not very good at continuous, but then computers in general aren't, and tend to end up treating the problem in a somewhat quantum fashion. So, if you're attempting to replicate a real-world system, you always have some kind of information loss if the system contains any continuous process. And this is all assuming you can capture enough information about the thing to know how it works.

I'm kind of surprised at your thought towards the end though - if anything, I would think it would be more appealing to the analysts, although perhaps your descriptions are slightly different to what I'm thinking. In my experience, OO tends to appeal to people who want to map the software onto the problem directly, essentially making a little world inside the computer. The abstraction side of things is very rarely used in real-world OO, again, IME.

    You may not have experienced the tendancy for people using OO to overabstract things. But I certainly have run into plenty of that.

    As for my final thought, pick up a design patterns book, and read it. Think about it in light of the two basic patterns of thought that I described for mathematics. If you can't see how it more closely resembles the algebraic mode of thought, then I probably didn't describe it clearly enough. For the real explanation I'd have to inflict a few months of advanced math on you. After you'd experienced figuring out, say, how homology groups work (for a demonstration of algebra) and various epsilon-delta proofs (for a taste of analysis), then you'd know directly the distinction that I am trying to describe.
