In quantum mechanics, the three pictures are also called Dynamical pictures. What are the three pictures of quantum mechanics? In many cases general `dissipative' systems can be viewed as small perturbations of Hamiltonian systems. Here simple may refer to `linear' or `integrable' or `normal form truncation', etc. The principle of perturbation theory is to study dynamical systems that are small perturbations of `simple' systems. What is the principle of perturbation theory? In physics, the Heisenberg picture (also called the Heisenberg representation) is a formulation (largely due to Werner Heisenberg in 1925) of quantum mechanics in which the operators (observables and others) incorporate a dependency on time, but the state vectors are time-independent, an arbitrary fixed basis rigidly. Uncertainty principle, also called Heisenberg uncertainty principle or indeterminacy principle, statement, articulated (1927) by the German physicist Werner Heisenberg, that the position and the velocity of an object cannot both be measured exactly, at the same time, even in theory. In the SchrГ¶dinger picture, the operators are constant and the state vectors evolve with time.

In the Heisenberg picture, the state vectors are time-independent and the operators that act on them vary with time. This is the doctrine of the Upanishads.вЂќ What is the difference between Heisenberg and Schrodinger? If the world is indeed created by our act of observation, there should be billions of such worlds, one for each of us. In his 1944 book What is Life?, SchrГ¶dinger took on a peculiar line of thought. The Upanishads say that the observer and the observed are the same things. Werner Heisenberg was even more confuzzled, because if an electron was a particle, it was very, very hard to figure out where exactly the dang thing was. His concepts were said to be too abstract and his math was unfamiliar. In contrast to SchrГ¶dinger, physicists liked to hate on Heisenberg. Why does Werner Heisenberg hate Schrodinger's theory? The problem now was that quantum theory was not relativistic the quantum description worked for particles moving slowly, but not for those at high or 'relativistic' velocities, close to the speed of light. What did Schrodinger and Heisenberg discover?Д«y the end of the decade Erwin SchrГ¶dinger and Werner Heisenberg had invented the new quantum theory of physics. The SchrГ¶dinger model assumes that the electron is a wave and tries to describe the regions in space, or orbitals, where electrons are most likely to be found. A powerful model of the atom was developed by Erwin SchrГ¶dinger in 1926.
