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 ...

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 ...

Though as with so many independent inventors the origins of computing can be said to have been arrived at through the work of many people, Alan Turing is certainly one of the foundational figures in ...
