You call yourself a scientist?
No, I don't. Maybe you missed my sarcasm...if we follow Petros logic, addition of any quality cannot be growth unless it produces a new maximum. Afterall, the American economy he says can't be growing because it is recovering from a large recession.
By that same logic, the man who gains weight after losing weight, isn't really gaining weight, they are simply recovering. That's asinine. Similarly, species that reach historic lows are not gaining when their population goes up...tumors that shrink and then begin to grow again are not actually growing, they are recovering, according to Petros logic.
I can think of plenty of examples from my own field where a quantity gets smaller and then larger again. Antibodies and viral pressure in challenge tanks, all sorts of things biologically go up and down, deterministically as well as randomly. We don't say that they aren't growing in number or gaining in some fashion simply because at one point there was more...
