... or follow just one path. One object might pass right through another. What happens to a particle in one place can have a direct effect in another place. Yet, we believe in these bizarre laws because for more than 75 years, we’ve used them to predict how atoms and tiny particles behave. The behavior ...

Path Integrals in Quantum Mechanics
... The conventional formulation of quantum mechanics as it is taught to students is based on the Schrödinger equation. This is in some contrast to the actual situation in theoretical physics, where all modern developments make extensive use of the path integral formalism, in particular in modern field ...

... Here the units of length and time have been chosen so that Planck’s constant is equal to 1. The particle is moving in the absence of external forces. • In the traditional classification of PDEs, the Schördinger equation is neither elliptic, parabolic, nor hyperbolic. • The physical interpretation, ...
