Glad you say so. This is *not* true for
Hi Wei Dai,
About books. Concerning the provability logics I always mentionned
the Boolos 1993 (or even his lovely lighter Boolos 1979), but I would
like to mention also the book Self-reference and modal logic by
Smorynski. The only problem is its very little caracters; I should go
to the
Thanks. I read it quickly. I didn't understand the details.
I have no really opinion. I have been more impressed by Freedman
analogical quantum machine, but Calude suggestion is of the same
type. This could lead to a refutation of comp, not of Church
thesis imo. Those machine does really not

(This assumes that the two TMs use the same basic alphabet of characters
for their input tape.)
OK. That follows from Church Thesis.

Sorry, I mixed up soundness and consistency here. It doesn't affect my

Category theory is interesting in that respect, but beware
