And if you can't do it (and you most certainly can not do it! ) I want to know why you can't if as you say mathematics is more fundamental than physics. I think the reason may be that mathematics is NOT as fundamental as physics , and so theorems of arithmetic are not as important , and not as true , and not as real , as the laws of physics. > > > Just read any book on the subject. > No book on that subject or on any other subject can perform a calculation, but a silicon microprocessor can. > > > I already gave you the definition by Davis. > No definition by Davis or by anybody else can perform a calculation, but a silicon microprocessor can. > > > Nothing physical is assume, > And no calculation is performed. > > > It describes the realities accessible from the different points of view. > If it's not made of matter that obeys the laws of physics no calculation is performed from ANY point of view. > > You just use a no standard not well defined notion of physical > computation.
