„We had a large old-fashioned battery, a wet cell, in the kitchen, hooked up to an electric bell. The bell was too complicated to understand at first, and the battery, to my mind, was more immediately attractive, for it contained an earthenware tube with a massive, gleaming copper cylinder in the middle, immersed in a bluish liquid, all this inside an outer glass casing, also filled with fluid, and containing a slimmer bar of zinc. It looked like a miniature chemical factory of sorts, and I thought I saw little bubbles of gas, at times, coming off the zinc. The Daniell cell (as it was called) had a thoroughly nineteenth-century, Victorian look about it, and this extraordinary object was making electricity all by itself—not by rubbing or friction, but just by the virtue of its own chemical reactions.“

„The signs on Bell’s door read “J. Bell” and “M. Bell.” I knocked and was invited in by Bell. He looked about the same as he had the last time I saw him, a couple of years ago. He has long, neatly combed red hair and a pointed beard, which give him a somewhat Shavian figura. On one wall of the office is a photograph of Bell with something that looks like a halo behind his head, and his expression in the photograph is mischievous. Theoretical physicists’ offices run the gamut from chaotic clutter to obsessive neatness; the Bells’ is somewhere in between. Bell invited me to sit down after warning me that the “visitor’s chair” tilted backward at unexpected angles. When I had mastered it, and had a chance to look around, the first thing that struck me was the absence of Mary. “Mary,” said Bell, with a note of some disbelief in his voice, “has retired.” This, it turned out, had occurred not long before my visit. “She will not look at any mathematics now. I hope she comes back,” he went on almost plaintively; “I need her. We are doing several problems together.” In recent years, the Bells have been studying new quantum mechanical effects that will become relevant for the generation of particle accelerators that will perhaps succeed the LEP. Bell began his career as a professional physicist by designing accelerators, and Mary has spent her entire career in accelerator design. A couple of years ago Bell, like the rest of the members of CERN theory division, was asked to list his physics speciality. Among the more “conventional” entries in the division such as “super strings,” “weak interactions,” “cosmology,” and the like, Bell’s read “quantum engineering.”“

„I first saw them in 1978. At the time, I knew a lot about chimps, because I had been studying them. I saw the bonobos at a zoo in Holland, and I thought immediately, they're totally different.“

The Bonobo in All of Us (2007), Context: I first saw them in 1978. At the time, I knew a lot about chimps, because I had been studying them. I saw the bonobos at a zoo in Holland, and I thought immediately, they're totally different. The sense you get looking them in the eyes is that they're more sensitive, more sensual, not necessarily more intelligent, but there's a high emotional awareness, so to speak, of each other and also of people who look at them.
