Theoretical Physics: When the Doer Met the Dreamer

Frequent Director's Visitor Graham Farmelo reviews The Quantum Labyrinth: How Richard Feynman and John Wheeler Revolutionized Time and Reality by physicist Paul Halpern. The work, he writes, “confirms the received opinion that Feynman was one of the greatest intuitive problem-solvers in twentieth-century physics, a world-class doer. But I suspect that many readers will take most pleasure from the account of Wheeler's inspired dreaming. As Dyson told me: “Posterity has given Feynman his due, but Wheeler has been cruelly underrated.”
