For several years, [Jim] has wanted to construct a fully-mechanical universal Turing machine. Without the help of any electronic circuits or electrical input, his goal was to build the machine using ...

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 ...

Turing machines are widely believed to be universal, in the sense that any computation done by any system can also be done by a Turing machine. In a new article, researchers present their work ...

Two researchers in the Netherlands helmed the construction of a LEGO Turing machine, a quirky manifestation of the classic computer science concept first devised by Alan Turing in 1936. The device, ...

David Craven does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond their ...

It might be useless and kind of harsh looking, but this all-mechanical Turing machine is a great exercise in geekdom. With more than 15 years experience testing hardware (and being obsessed with it), ...

Alan Turing was an English mathematician, wartime code-breaker and pioneer of computer science. Photo: Alan Turing with two colleagues and a Ferranti computer in January 1951. Turing had previously ...

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. It's hard to overestimate Alan Turing ...
