One difference between rule driven Turing-complete machines and empirically observed biological systems could be that the adaptive agents in biological systems have certain "unity of consciousness ...

Unlike the machine Alan Turing hypothesized, [Richard J. Ridel] decided on building a machine that accommodated three data elements (0, 1, and “b” for blank) and three states.

The Turing machine is, above all else, a thought experiment, an abstraction of how a mechanical computing machine could work. Building a working one seems to be missing the point.

Thermodynamics of computation: A quest to find the cost of running a Turing machine Date: August 26, 2020 Source: Santa Fe Institute Summary: Turing machines are widely believed to be universal ...

But we didn’t know how complex they would have to be. Now, Yedidia and Aaronson have created a Turing machine with 7918 states that has this property. And they’ve named it “Z”.

Such is Turing's legacy: that of a nested chain of pretenses, each pointing not to reality, but to the caricature of another idea, device, individual, or concept.

IN 1935, Alan Turing set out to build a reputation by outflanking the world’s leading mathematician. Turing was 22 years old, and a new fellow at Cambridge. His target, David Hilbert, was the ...
