If you want to use Euclidean geometry or even the sort of non-Euclidean geometry Einstein used you've got to use standard arithmetic, but there are other ways. For example, in the 7-adic system the distance between 56666 and 66666 is smaller than the distance between 66665 and 66666; and 28814 is closer to 2 than 2 is to 3. > >** > *Computation are not physical by definition.* > Sure if you define computation as something that happens in heaven that can never be observed, but only somebody more interested in pondering the number of angles that can dance on the head of a pin than in computers or science or anything humans can detect with their senses would do so. > > >** > *If you can find just one paper providing a physical definition of > computation,* > A physical computation is a computation and a computation is a physical computation, in other words the term "physical computation" is redundant, there are only computations. *>You asked me this before.
