Quantum field theory In theoretical physics, quantum field theory QFT is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics xi and is used to construct physical models of subatomic particles in particle physics and quasiparticles in condensed matter physics QFT treats particles as excited states also called quanta of their underlying fields, which are Quantum theory This disambiguation page lists articles associated with the title Quantum theory If an internal link led you here, you may wish to change the link to point directly to the intended article. Quantum Theory Definition of Quantum Theory by Merriam Quantum theory definition is a theory in physics based on the concept of the subdivision of radiant energy into finite quanta and applied to numerous processes involving transference or transformation of energy in an atomic or molecular scale. Quantum Theory Demonstrated Observation Affects Reality One of the most bizarre premises of quantum theory, which has long fascinated philosophers and physicists alike, states that by the very act of watching, the observer affects the observed reality. Understand Physics Through Quantum Field Theory A book that finally gets it right Brooks presents the news about quantum field theory in a non technical but accurate manner His explanatory technique of using different colors to represent different fields is a stroke of pedagogical genius. Consistent Quantum Theory Back to main page This page is maintained by Vlad Gheorghiu Last modified Aug quantum mechanics Definition, Development, Equations Quantum mechanics Quantum mechanics, science dealing with the behavior of matter and light on the atomic and subatomic scale It attempts to describe and account for the properties of molecules and atoms and their constituents electrons, protons, neutrons, and other esoteric particles such as quarks and gluons. On the place of subjectivity in quantum theory Philsci I argue that the presence of subjective, qualitative consciousness in our world is at first sight maybe surprisingly related with ontological complexities surrounding measurement in quantum theory Both issues can be cleared up by a suitable redefinition of the notion of observer by equipping them with subjective ontology and waving goodbye to the global one, covering the whole Faith and Quantum Theory by Stephen M Barr Articles Quantum theory is unsettling Nobel laureate Richard Feynman admitted that it appears peculiar and mysterious to everyone both to the novice and to the experienced physicist Niels Bohr, one of its founders, told a young colleague, If it does not boggle your mind, you understand nothing Quanta and Wave Particle Duality Quantum Theory and the The earliest steps in the development of quantum physics arose from the investigation into something as mundane as why metal glows red when hot The great German physicist Max Planck had been studying the problem of black body radiation in the late s The problem Planck was dealing with was the observation that the greatest amount of energy being radiated from a black body or any
