I have no doubt that Wol knows his stuff when it comes to physics, far better than I do. I do have severe doubts about the applicability of reasoning about physical models to computing, though we're getting into philosophy here.

I'm certainly willing to entertain language notions - I just haven't heard anything concrete enough to serve as the basis for a data model. Loose correspondence to English is, in my opinion, not a good metric.
