A theoretical computer built in a mixed-up mathematical universe might not sound like the most practical invention. But the discovery shows that computation can turn up in the most unlikely places, ...

Theory of Computation offers a rigorous mathematical framework that underpins our understanding of what can be computed and how efficiently these computations may be performed. It encompasses ...

The history of digital computing can be divided into an old testament and a new testament. The prophets of the old testament, led by Gottfried Wilhelm Leibniz in the 1670s, supplied the logic; those ...
