Three Degrees above Zero

In June 1982 I was spending my usual summer at the Aspen Center for Physics when I was approached by Philip Anderson. He was a very persuasive person who had won the Nobel Prize five years earlier. I didn’t really know him but he presented me with almost a command. It looked as if AT&T was going to be broken up and Anderson was worried about what might happen to Bell Laboratories, where he worked. He wanted me to write something about it, preferably for the New Yorker. My problem was that I knew almost nothing about Bell Labs. I knew that the transistor had been discovered there as had the radiation left over from the Big Bang. I also knew that it was an enormous laboratory employing some 25,000 people. Under these circumstances how could I possibly write something that made any sense? But Anderson is as I said a very persuasive person so I agreed to try something.

In Chitral

Sometime in the winter of 1969 a Pakistani colleague told me that the Ford Foundation had created visiting professorships at the University of Islamabad and asked if I would like one. At the time I was always open to travel adventure so I said sure. After I was appointed, the question arose as to how to get there. To me the obvious answer was to drive. I put the proposition to William Shawn, the editor of the New Yorker, who thought it an interesting idea. The magazine put up enough money for me to buy a Land Rover Dormobile. This legendary vehicle, which is no longer manufactured, had sleeping bunks and a stove – perfect for the job. I enlisted my friend the Chamonix guide Claude Jaccoux and his wife Michèle and in early September we set out. It took about three weeks to drive from France through Italy, Yugoslavia, Greece, Turkey, Iran and Afghanistan and then over the Khyber Pass into Pakistan.

‘Stick with me, kid’

In the spring of 1959 I won a National Science Foundation fellowship that enabled me to do physics anywhere I wanted to. I chose Paris. I had spent the last couple of years at the Institute for Advanced Study in Princeton and wanted very much to go to a city. Murray Gell-Mann was paying a visit to Princeton at the time. I had written a paper with a colleague suggesting how an idea of Gell-Mann’s could be tested experimentally. He dropped round to my office and asked what I was doing the following year. I told him. To my surprise he said he was going to Paris too, and added: ‘Stick with me, kid, and I’ll put you on Broadway.’ I didn’t then tell him that I was familiar with him from another life.

Incredible Untrue Events

Trevor Nunn’s movie Red Joan, starring Sophie Cookson and Judi Dench, claims to be ‘based on incredible true events’, namely the life of Melita Norwood. But the story told by the film is so far from the truth it’s nonsense.

Memories of Heinz Pagels

Reading Elaine Pagels’s new book, Why Religion? A Personal Story, brought back memories of my friendship with her husband Heinz Pagels. I met him in 1966 when he arrived at the Rockefeller University. I had no knowledge of his work but he struck me as a golden boy. He was very handsome and looked more like someone who might sing folk songs for a living than a theoretical physicist. He had been born in New York City in 1939 and attended Princeton. He then went to Stanford for his graduate work and took his PhD in 1965 under the direction of Sidney Drell. I recently looked at the paper they published and it still holds up. Heinz then spent a brief time at the University of North Carolina. I do not know how he found his way to the Rockefeller but there he was.

Anti-Semitism in America

With what just happened in Pittsburgh it is easy to forget what things were like in the 1930s in America. I remember because I was growing up then. We used to listen to Father Coughlin on the radio. He said things like this:

Four-Dimensional Proust

I am rereading Proust. If anyone asks why, I tell them the story of Franklin Roosevelt and Oliver Wendell Holmes. Roosevelt paid a visit to the aged Holmes to find him reading Plato in Greek. He asked him why and Holmes replied: ‘To improve my mind, Mr President.’

One Cubit the More

With the death of Stephen Hawking and the discussion it produced on black holes it was a little surprising that there was little or no mention of the man who created the subject, J. Robert Oppenheimer, who died in 1967 at the age of 62. He often said that the J stood for nothing, but I have a copy of his birth certificate on which his first name is given as ‘Julius’. In his day Oppenheimer was the most celebrated physicist in the United States. His portrait had been on the cover of Time magazine and he was on first-name terms with much of the Washington establishment, until he lost his security clearance in 1954. It was said by people who had known him before that the experience changed him profoundly and he appeared diminished. He did not appear diminished to me when when I arrived at the Institute for Advanced Study in Princeton in 1957 and was ushered into his office. The first thing he asked me was what was ‘new and firm’ in physics. I was spared trying to give an answer when his phone rang. It was from his wife. ‘It was Kitty,’ he said when he hung up. ‘She has been drinking again.’

Remembering Stephen Hawking

I had one encounter with Stephen Hawking. He came in the summer of 1989 to the Aspen Center for Physics and had the office next to mine. He travelled with an entourage with whom he could communicate with his voice synthesiser. His hands still worked well enough. He gave a full house public lecture and afterwards Sidney Coleman presided over a question session. Hawking had to type out all his answers on his voice synthesiser which took a lot of time. At one point Sidney said: 'You can have it fast or you can have it good.' If I had asked a question, it would have been: how did he come up with the idea of Hawking radiation? I have always found his paper hard going and have always marvelled at the simple result at the end. In A Brief History of Time he gives an account which explains the phenomenon but not the result.

Heavy Water

‘The Iranian regime has committed multiple violations of the agreement,’ Donald Trump said last week. ‘For example, on two separate occasions, they have exceeded the limit of 130 metric tons of heavy water.’ In 1931, the American physical chemist Harold Urey discovered deuterium, the isotope of hydrogen that has a neutron in its nucleus along with a proton. He manufactured some ‘heavy water’ (D2O) and, I think, drank some. Heavy water remained an interesting laboratory phenomenon until the Second World War, when it took on new importance since it plays a role in the production of plutonium, which does not exist naturally on earth.
