On being an eternal student.

Freeman Dyson died February 28th this year. There are many obituaries of this great mind and eternal rebel. His book, Disturbing the Universe, is for me one of a handful that gets the fundamental nature of discovery in science and how science interacts with other modes of being human. His intellectual bravery and honesty shine through most of his writings. John Naughton had a nice quote from him a short while back.

Some mathematicians are birds, others are frogs. Birds fly high in the air and survey broad vistas of mathematics out to the far horizon. They delight in concepts that unify our thinking and bring together diverse problems from different parts of the landscape. Frogs live in the mud below and see only the flowers that grow nearby. They delight in the details of particular objects, and they solve problems one at a time. I happen to be a frog, but many of my best friends are birds. The main theme of my talk tonight is this. Mathematics needs both birds and frogs.

In truth he was both frog and an albatross. Here are some words from his obituary in PNAS.

During the Second World War, Dyson worked as a civilian scientist for the Royal Air Force’s Bomber Command, an experience that made him a life-long pacifist. In 1941, as an undergraduate at Trinity College, Cambridge, United Kingdom, he found an intellectual role model in the famed mathematician G. H. Hardy, who shared two ideas that came to define Dyson’s trajectory: “A mathematician, like a painter or a poet, is a maker of patterns,” and “Young men should prove theorems; old men should write books.”

Heeding the advice of his undergraduate mentor, Dyson returned to his first love of writing. He became well-known to a wide audience by his books Disturbing the Universe (1979) (1) and Infinite in All Directions (1988) (2), and his many beautiful essays for The New Yorker and The New York Review of Books. In 2018, he published his autobiography, Maker of Patterns (3), largely composed of letters that he sent to his parents from an early age on.

And as for us eternal students, at least I have one thing in common.

…Dyson never obtained an official doctorate of philosophy. As an eternal graduate student, a “rebel” in his own words, Dyson was unafraid to question everything and everybody. It is not surprising that his young colleagues inspired him the most.
