Freeman John Dyson FRS (15 December 1923 – 28 February 2020) [1] was a British-American theoretical physicist and mathematician known for his works in quantum field theory, astrophysics, random matrices, mathematical formulation of quantum mechanics, condensed matter physics, nuclear physics, and engineering.
Freeman Dyson proposed that trans-Neptunian objects, rather than planets, are the major potential habitat of life in space. [ citation needed ] Several hundred billion to trillion comet -like ice-rich bodies exist outside the orbit of Neptune , in the Kuiper belt and Inner and Outer Oort cloud .

The Schwinger–Dyson equations (SDEs) or Dyson–Schwinger equations, named after Julian Schwinger and Freeman Dyson, are general relations between correlation functions in quantum field theories (QFTs).
Freeman Dyson in 2005. Astrochicken is the name given to a thought experiment expounded by theoretical physicist Freeman Dyson.An Astrochicken is a small, one-kilogram spacecraft, a self-replicating automaton that could explore space more efficiently than a crewed craft could due to its innovative mix of technology.
In scattering theory, a part of mathematical physics, the Dyson series, formulated by Freeman Dyson, is a perturbative expansion of the time evolution operator in the interaction picture. Each term can be represented by a sum of Feynman diagrams .
Inspired by the 1937 science fiction novel Star Maker by Olaf Stapledon, [5] the physicist and mathematician Freeman Dyson was the first to formalize the concept of what became known as the "Dyson sphere" in his 1960 Science paper "Search for Artificial Stellar Sources of Infra-Red Radiation". Dyson theorized that as the energy requirements of ...
Freeman Dyson in 2005. Dyson's eternal intelligence (the Dyson Scenario) is a hypothetical concept, proposed by Freeman Dyson in 1979, by which an immortal society of intelligent beings in an open universe may escape the prospect of the heat death of the universe by performing an infinite number of computations (as defined below) though expending only a finite amount of energy.
