When entering the office of a physics professor it is no surprise to find that space is at a premium, with books and research papers piled high on every available surface. In that respect, the office of Brian Josephson on the top floor of the Cavendish Laboratory in Cambridge is no exception. But it would be wrong to conclude that Josephson is a typical physicist, and a quick glance at those books reveals why. With titles such as Consciousness Explained and Clairvoyant Reality, it is apparent that he is interested in subjects well beyond the scope of the average physicist.
