tubulin molecules can flip between two states, propagating a ripple along the tube wall. The scale is small enough for quantum effects to matter, and Hameroff suggests quantum error correction keeps the ripples from decohering too fast. Because the processing is happening at a molecular level rather than at

is also, interestingly, the protein that unzips the double helix when a cell divides, and so plays a fundamental role in our evolution. Penrose and Hameroff suggest these tubes form the true processing element in our brains. The walls of the tubes are formed of successive alpha and beta tubulin molecules.

in non-computable thought. It is his ‘machines’ we will look at next. Penrose-Hameroff Machines, aka Brains Roger Penrose of Oxford University and Stuart Hameroff of the University of Arizona have proposed a very different way to understand the workings of the brain. They focus on the much smaller scale structu

a Halting procedure. A Universal Turing Machine is a relatively small program. Roger Penrose gives a three-page example in The Emperors New Mind, and Stephen Wolfram has implemented one using a cellular automaton with as few as five component parts. A Halting Program running on such a machine should be able to co
