With all my recent criticism of ‘quantum consciousness‘ I thought you might be interested in hearing about a quantum effect that ‘mainstream’ physicists think is exhibited in biological organisms.

What the Universe Is Like My first full-time physics teaching job was at a Church of England School in Wigan.

Artists who usually demonstrate extraordinary observational skills for landscapes, animals, and human interactions, seems to have a terrible blind spot for the relatively simple rainbow.
