Mike Davey wanted to build a real Turing machine, but unfortunately he could not find the infinitely long tape required for the project. His solution? Using 1000 feet of white 35mm film leader and a ...

With regard to my previous blog on a One-bit processor and a mega-cool Turing machine, I’ve been bouncing around the Internet discovering all sorts of cool things… But before we hurl ourselves ...

The Church-Turing limit restricts all current computation, including quantum computers, to rational number computation. This is because quantum computer designs (still not scalable even with high ...

In computational complexity theory, P and NP are two classes of problems. P is the class of decision problems that a deterministic Turing machine can solve in polynomial time. In useful terms, any ...

The history of digital computing can be divided into an old testament and a new testament. The prophets of the old testament, led by Gottfried Wilhelm Leibniz in the 1670s, supplied the logic; those ...
