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 ...

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 ...

For something that has been around since the 1930s and is so foundational to computer science, you’d think that the Turing machine, an abstraction for mechanical computation, would be easily ...
