You think arithmetical reality is the only reality there is and the book is real but for unknown reasons it can't calculate 2+2. As for me I think if you want to avoid confusion you should stop referring people to a book whenever they ask for a demonstration of a non-physical calculation. > *> If you would open and read the books,* OK already you're asking me to do something mathematics could never do. Forget reading just opening a book requires energy, and all the Real Numbers and all the Complex Numbers and all the p-adic numbers put together don't have one electron volt's worth of energy. And even after I've finished my arduous struggle and managed to get the book open it orders me to perform calculations, and that will require even more energy. > *> you would see that they do not just gives the recipe, but shows that > those recipe are enacted* Yes, the book shows recipes for getting answers to questions and how those recipes are enacted by matter that obeys the laws of physics. The book will say things like "there exists an element x in the set Y with blah blah properties" and that may indeed be true but there is are also a infinite number of elements in set Y that do NOT have the blah blah property, and then the book will either give an existence proof that the element x must be in that infinite sea of other elements somewhere but give no hint of how to find out what it is, or it will give a recipe for finding x, a recipe that only matter that obeys the laws of physics can perform. The recipe in the book will say "let n be blah blah" but an equation can't "let" anything, only you can. And the recipe will say things like "multiply equation 10-42 by blah blah, cancel out what can be canceled out, then integrate from zero to n and you will find x". But a equation can't "let" things or “multiply" things or "cancel out" things or "integrate” things because equations can’t “do” anything, only you can “do” things, only you can perform those calculations and fortunately you are made of matter that obeys the laws of physics. > *> I gave explanation, but to do this here would be very long.* I have no doubt it would be long, very very long, but I don't want an explanation, I want a DEMONSTRATION, a demonstration of a non-physical calculation, and I'm sure the Intel Corporation would like to see that demonstrated too. I don't demand anything fancy, 2+2=4 would be fine. The fundamental problem is that in mathematical heaven incorrect calculations are, not astronomically but INFINITELY, more common than correct ones, and the ghost of Plato has no way of telling one from the other, so its a good thing that matter can. > *> do you understand the difference between a book and a mathematical > reality?* Yes, but then unlike you I don't believe the mathematical language created everything, and I don't think the English language did either.
