query: When was quantum field theory developed?
passage: Quantum field theory
Quantum field theory naturally began with the study of electromagnetic interactions, as the electromagnetic field was the only known classical field as of the 1920s.[8]:1
passage: Quantum fiction
Quantum fiction brings quantum theory forward as the explanation behind the concept of life imitating art and art imitating life via substantiation of literary plot developments, time sequence, character experiences and other literary elements based on quantum mechanics. The term Quantum fiction is etymologically based on the discovery of Max Planck, who first used the word quantum to describe the minute forces at play in the realm of physics. The field was pioneered by quantum physicists Erwin Schrödinger, Werner Heisenberg, Wolfgang Pauli, Niels Bohr, and Eugene Wigner, as well as contentions of Louis DeBroglie, Max von Laue and Albert Einstein. One contention, among others, is that quantum mechanics is a statistical approximation to a deeper reality which behaves predictably via the observer being an inextricable part of reality (Observer effect (physics)).
