An unlimited board is a board that is "enough" big.

What is wrong with computational histories?

Yes, I was not on the list then.

I do not believe in that quantum mechanics implies statistically interfering computations. I believe that quantum mechanics is deterministic. Microcosmos looks indeterministic just because we do not know yet what is happening at the Planck scale. You must think of that a quark is 100.000.000.000.000.000.000 times bigger than the Planch length, so many things can happen in that interval. -- Torgny Tholerus --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
