My brother Fairchild has just bought himself an "electronic janitor", a costly device which, I understand, keeps his house at an even temperature of 70 degrees without any effort on his part whatsoever. I don't know quite how it works, but it has something to do with molecules and the quantum theory.

A simple calculation shows that from the classical theory follows that we should find a broadening of the beam with the maximum intensity on the place of the beam without field. However, from the quantum theory follows that we should find there no intensity at all, and deflected molecules on both sides. The beam should split up in two beams corresponding to the two orientations of the magnet. The experiment decided in favor of the quantum theory.

"When I got my first paycheck, $5'000 or something. I bought a Leger and I bought a Frida Kahlo self-portrait, but I don't know which came first. But I remember buying it and I had just gotten married and it looked completely out of place in my house in Malibu." (When asked what was the first painting she bought). Aperture Magazine 1999

Does life in some way make use of the potentiality for vast quantum superpositions, as would be required for serious quantum computation? How important are the quantum aspects of DNA molecules? Are cellular microtubules performing some essential quantum roles? Are the subtleties of quantum field theory important to biology? Shall we gain needed insights from the study of quantum toy models? Do we really need to move forward to radical new theories of physical reality, as I myself believe, before the more subtle issues of biology — most importantly conscious mentality — can be understood in physical terms? How relevant, indeed, is our present lack of understanding of physics at the quantum/classical boundary? Or is consciousness really “no big deal,” as has sometimes been expressed?
It would be too optimistic to expect to find definitive answers to all these questions, at our present state of knowledge, but there is much scope for healthy debate...
