I ask this because I am studying Carl Hewitt's Actor Model...
Also know today as "object oriented" languages. c++ win against
smaltalk, which won against the Actor model, but the idea is the same,
basically. It is efficacious, but the math and semantics is still
unclear to me. It is a sort of vague polymorphic lambda calculus. I
did love a long time ago, the "actor model". It is somewhat
psychologically sad that the term "object" replaced the term "actor".

Hi jason,
Do programs have to be "deterministic". What definition of
deterministic are you using?

Hi Jason,
"The first, second, 10th, 1,000,000th, and 10^100th, and
10^100^100th state of the UD's execution are mathematical facts ..."
Umm, how? Godel and Matiyasevich would disagree! If there does not
exist a program that can evaluate whether or not a UD substring is a
faithful representation of a "true theorem", then how is it "a fact"?
That depends on whether the UD is deterministic or not.
It is. The evolution of any Turing machines is deterministic.
If it is, then, its Nth state is a fact. (It doesn't need to be run
or evaluated, and the Nth state may be a fact that nobody knows,
like the googolth digit of pi, assuming no one's worked that out.)
Right. :-)
The fact that I remember drinking a glass of water is as much a
mathematical fact about the UD, as the fact as the third decimal
digit of Pi is 4.
