The Universal Perspex Machine

A seminar at Goldsmiths College, London, at 4 p.m. on Wednesday 8 June, 2005.

The universal perspex machine arose from the unification of geometry with the Turing machine. Because geometry is continuous the perspex machine is super-Turing and, more generally, it is super-symbolic. It can compute everything that is expressible in symbols - and more.

The perspex machine is very simple, but it is so different form traditional models of computation that many people have difficulty approaching it. The seminar will deal with this by giving a very short introduction to the perspex machine and then addressing questions from the audience. A crib sheet of questions is provided to prompt discussion.
