WebIn scattering theory, a part of mathematical physics, the Dyson series, formulated by Freeman Dyson, is a perturbativeexpansion of the time evolution operatorin the interaction picture. Each term can be represented by a sum of Feynman diagrams. Dyson admitted his record as a prophet was mixed, but thought it is better to be wrong than vague, and that in meeting the world's material needs, technology must be beautiful and cheap. My book The Sun, the Genome, and the Internet (1999) describes a vision of green technology enriching villages all over the world and halting the migratio… Dyson admitted his record as a prophet was mixed, but thought it is better to be wrong than vague, and that in meeting the world's material needs, technology must be beautiful and cheap.

WebDec 22, 2004 · New kinds of statistical ensemble are defined, representing a mathematical idealization of the notion of ``all physical systems with equal probability.'' Three such ensembles are studied in detail, based mathematically upon the orthogonal, unitary, and symplectic groups. The orthogonal ensemble is relevant in most practical circumstances, … A Dyson sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its solar power output. The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can … See more The physicist and mathematician Freeman Dyson is credited with being 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 … See more In fictional accounts, the Dyson-sphere concept is often interpreted as an artificial, hollow sphere of matter around a star. This perception is based on a literal interpretation of Dyson's original 1960 paper. In response to letters prompted by some papers, … See more A precursor to the concept of Dyson spheres was featured in the 1937 novel Star Maker by Olaf Stapledon.

The number of craft required to obtain, transmit, and maintain a complete Dyson sphere exceeds … See more In Dyson's original paper, he speculated that sufficiently advanced extraterrestrial civilizations would likely follow a similar power-consumption pattern to that of humans, and would eventually build their own sphere of collectors.
