The life and work of Freeman Dyson—renowned scientist, visionary, and iconoclast—and his particular way of thinking about deep questions.

Freeman Dyson (1923–2020)—renowned scientist, visionary, and iconoclast—helped invent modern physics. Not bound by disciplinary divisions, he went on to explore foundational topics in mathematics, astrophysics, and the origin of life. General readers were introduced to Dyson's roving mind and heterodox approach in his 1979 book Disturbing the Universe, a poignant autobiographical reflection on life and science. “Well, Doc, You're In” (the title quotes Richard Feynman's remark to Dyson at a physics conference) offers a fresh examination of Dyson's life and work, exploring his particular way of thinking about deep questions that range from the nature of matter to the ultimate fate of the universe.

The chapters—written by leading scientists, historians, and science journalists, including some of Dyson's colleagues—trace Dyson's formative years, his budding interests and curiosities, and his wide-ranging work across the natural sciences, technology, and public policy. They describe Dyson's innovations at the intersection of quantum theory and relativity, his novel nuclear reactor design (and his never-realized idea of a spacecraft powered by nuclear weapons), his years at the Institute for Advanced Study, and his foray into cosmology. In the coda, Dyson's daughter Esther reflects on growing up in the Dyson household. “Well, Doc, You're In” assesses Dyson's successes, blind spots, and influence, assembling a portrait of a scientist's outsized legacy.

  • "This remarkable volume not only surveys the staggeringly diverse activities of Freeman Dyson — spanning World War II, the Cold War, and the cosmos — but also what thinking like Dyson must have been like. It's engrossing."

    Michael D. Gordin

    Rosengarten Professor of Modern and Contemporary History in the History Department, Princeton University

  • “These riveting essays will appeal to initiates as well as newcomers to Dyson's wide-ranging and playful genius.  His faith in science as a conspiracy of brains against ignorance remains particularly consoling and inspiring today.”

    Nell Freudenberger

    author of Lost and Wanted

  • “A wonderful series of vignettes on Dyson's singular path through the  universe, which left an indelible mark in a  wide range of fields, from quantum electrodynamics to matters of war and peace.”
