As a witness of that period, I am also deeply convinced that John Bell indirectly played a crucial role in the progress of the application of quantum mechanics to individual objects, microscopic and mesoscopic. The example of his intellectual freedom, that had led to the recognition of the importance of entanglement, was no doubt an encouragement to those who were contemplating the possibility of developing new approaches, beyond the so-efficient paradigm developed decades earlier. His example opened the gate for new quantum explorations.

At present we are living through an unusual period in time a new cosmic creation has become reality in the world, a creativity within ourselves which pervades our consciousness.... in this way the artist became the foundation on which progress in the reconstruction of life could advance beyond the frontiers of the all-seeing eye and the all-hearing ear. Thus a picture was no longer an anecdote nor a lyric poem nor a lecture on morality nor a feast for the eye but a sign and symbol of this new conception of the world which comes from within us.

I am a long-time admirer (and think myself a friend) of Israel. In the early 1970s, I played a key role in getting advanced weaponry released to the Israeli Air Force - capabilities it later put to active use. During that period, I made many official visits to Israel and established close relationships there. These contacts turned out to be useful during Operation Desert Storm, when, as chief of staff of the U. S. Air Force, I worked with my Israeli counterparts to help defend Israel from Iraqi Scud missile attacks.

If I choose to impose individual blame for all past social ills, there will be no one left to like in some of the most fascinating periods of our history. For example [...] if I place every Victorian anti-Semite beyond the pale of my attention, my compass of available music and literature will be pitifully small. Though I hold no shred of sympathy for active persecution, I cannot excoriate individuals who acquiesced passively in a standard societal judgment. Rail instead against the judgment, and try to understand what motivates men of decent will.

The most remarkable feature of Bell's work was undoubtedly the possibility it offered to determine experimentally whether or not Einstein's ideas could be kept. The experimental tests of Bell inequalities gave an unambiguous answer: entanglement cannot be understood as usual correlations, whose interpretation relies on the existence of common properties, originating in a common preparation, and remaining attached to each individual object after separation, as components of their physical reality.

Much of the early engineering development of digital computers was done in universities. A few years ago, the view was commonly expressed that universities had played their part in computer design, and that the matter could now safely be left to industry. [...] Apart from the obvious functions of keeping in the public domain material that might otherwise be hidden, universities can make a special contribution by reason of their freedom from commercial considerations, including freedom from the need to follow the fashion.
