Turing machines were first proposed by British mathematician Alan Turing in 1936, and are a theoretical mathematical model of what it means for a system to "be a computer." In a paper published in the ...

A mathematical model of computation. Named after English scientist Alan Turing, a Turing machine is a finite state machine that reads a tape divided into cells. The Turing machine examines the symbol ...

Vice reports that scientists have created the first known “chemical Turing machine,” meaning a liquid that can do the calculations that define a classic computer science standard. Juan Pérez-Mercader ...

One of the problems with a classic Turing machine is the tape must be infinitely long. [Mark’s] Turing Ring still doesn’t have an infinite tape, but it does make it circular to save space. That along ...

However, there's a problem with this, which I can't resolve. Anyone who's done a computing machinery course will have heard of the Halting Problem, or Self Applicability, or some variant thereof.

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 ...
