Freeman J. Dyson, noted physicist.
As a young graduate student at Cornell in 1949, Dr. Dyson wrote a landmark paper — worthy, some colleagues thought, of a Nobel Prize — that deepened the understanding of how light interacts with matter to produce the palpable world. The theory the paper advanced, called quantum electrodynamics, or QED, ranks among the great achievements of modern science.
But it was as a writer and technological visionary that he gained public renown. He imagined exploring the solar system with spaceships propelled by nuclear explosions and establishing distant colonies nourished by genetically engineered plants.

Dr. Dyson called himself a scientific heretic and warned against the temptation of confusing mathematical abstractions with ultimate truth. Although his own early work on QED helped bring photons and electrons into a consistent framework, Dr. Dyson doubted that superstrings, or anything else, would lead to a Theory of Everything, unifying all of physics with a succinct formulation inscribable on a T-shirt. In a speech in 2000 when he accepted the Templeton Prize for Progress in Religion, Dr. Dyson quoted Francis Bacon: “God forbid that we should give out a dream of our own imagination for a pattern of the world.”
Relishing the role of iconoclast, he confounded the scientific establishment by dismissing the consensus about the perils of man-made climate change as “tribal group-thinking.” He doubted the veracity of the climate models, and he exasperated experts with sanguine predictions they found rooted less in science than in wishfulness: Excess carbon in the air is good for plants, and global warming might forestall another ice age.
In a profile of Dr. Dyson in 2009 in The New York Times Magazine, his colleague Steven Weinberg, a Nobel laureate, observed, “I have the sense that when consensus is forming like ice hardening on a lake, Dyson will do his best to chip at the ice.”
He was also skeptical of the “nuclear winter” theory.
He considered himself an environmentalist. “I am a tree-hugger, in love with frogs and forests,” he wrote in 2015 in The Boston Globe. “More urgent and more real problems, such as the overfishing of the oceans and the destruction of wildlife habitat on land, are neglected, while the environmental activists waste their time and energy ranting about climate change.” That was, to say the least, a minority position.
He was religious but in an unorthodox way, believing good works to be more important than theology. “Science is exciting because it is full of unsolved mysteries, and religion is exciting for the same reason,” he said in his Templeton Prize acceptance speech. “The greatest unsolved mysteries are the mysteries of our existence as conscious beings in a small corner of a vast universe.”

He was also one of the folks behind Project Orion.
In the late 1970s Dr. Dyson turned full force to writing. Anyone with an interest in science and an appreciation for good prose is likely to have some Dysons on the shelf: “Disturbing the Universe,” “Weapons and Hope,” “Infinite in All Directions,” “The Sun, the Genome and the Internet.”
He also entered literature in a different way. He appeared in John McPhee’s book “The Curve of Binding Energy” (1974), a portrait of Ted Taylor, the nuclear scientist who led the Orion effort, and in Kenneth Brower’s “The Starship and the Canoe” (1978). In a memorable scene, Mr. Brower wrote of Dr. Dyson’s reunion with his son, George, who had turned his back on high technology to live in a treehouse in British Columbia and build a seafaring canoe. George Dyson later returned to civilization and became a historian of technology and an author. Dr. Dyson’s daughter Esther Dyson is a well-known Silicon Valley consultant.
Statement from the Institute for Advanced Study. This is a great line:
I’m going to have to start using “PhD proof” more often in conversation.
This is eloquently stated, and seems like a good note to end on:
