Murray Gell-Mann was a contemporary of mine in school, although he was three years ahead. He went to Yale at age 15, but he was around. And we had a maths teacher in common, a Mr Reynolds, a sulphurous man who would say the wonderful people he had in previous courses. Of course, Murray was a wonderful person from a previous course. And then afterwards, he would say, 'In Tarrytown, we bury our dead.' And that showed us exactly what we were. But you had to do these things, because there was a New York State Regents Exam, and you had to pass the Regents Exam, which I did. And then there was a college entrance exam, which I took. I don't know how I did. And at some point, there was a psychologist who came and did IQ tests. And the only thing that she told me about my IQ was that, of the three of us - my sister and brother were also at the school then - my sister had the highest IQ, my brother the second-highest, and I the third. But she didn't say what our IQs were and I've never known mine. I've not the slightest idea, nor any interest in what it is.
