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.
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.
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:
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.’
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.’
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.
‘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.
Not long after the Second World War, the scientists at Los Alamos realised that they could vastly improve the design of a nuclear bomb, making it light enough to fly on a rocket.
US presidents since John F. Kennedy have been followed everywhere by an army officer carrying a leather-bound metal Zero Halliburton briefcase. (Zero Halliburton was sold to a Japanese company in 2006, but Donald Trump hasn’t switched to an all-American manufacturer.) Inside the president’s ‘emergency satchel’, also known as the ‘nuclear football’, is a ‘black book’ containing such things as retaliatory options and the codes for launching them. The president has the power to choose any of these options and no one has the power to stop him.
In the early 1970s I wrote a profile of Albert Einstein for the New Yorker. I had known his secretary Helen Dukas since my days at the Institute for Advanced Study. She had come with him when he emigrated from Germany and lived in the Einsteins’ house in Princeton, which after his death she shared with his stepdaughter Margot. I asked if I could visit the house. She agreed. In Einstein’s study there was an etching of James Clerk Maxwell and one of Newton which had come out of its frame. This seemed symbolically correct. Helen offered to make lunch and while she was preparing the sandwiches she gave me a book to look at. It included a letter Einstein sent from Brussels to his wife Elsa in 1930.
