    Freeman Dyson, Math Genius Turned Visionary Technologist, Dies at 96

    Freeman J. Dyson, a mathematical prodigy who left his mark on subatomic physics before turning to messier subjects like Earth’s environmental future and the morality of war, died on Friday at a hospital near Princeton, N.J. He was 96.

    As a young graduate student at Cornell University 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.

    ......

    But his interests were not moored to the earth’s surface. Any advanced civilization, he observed in a paper published in 1960, would ultimately expand to the point where it needed all the energy its solar system could provide. The ultimate solution would be to build a shell around the sun — a Dyson sphere — to capture its output. Earthlings, he speculated in a thought experiment, might conceivably do this by dismantling Jupiter and reassembling the pieces.

    I have a feeling the Dyson sphere will last forever in sci-fi

    It's a big idea that goes round and round.
