www.ks.uiuc.eduApr 18, 2000 · For this purpose we will review the relevant concepts of Classical Mechanics. An important concept is that the equations of motion of Classical Mechanics can be based on a variational principle, namely, that along a path describing classical motion the action integral assumes a minimal value (Hamiltonian Principle of Least Action).
Quantum Physics II, Lecture Notes 1 - MIT OpenCourseWare
ocw.mit.eduIn classical mechanics the motion of a particle is usually described using the time-dependent position ix(t) as the dynamical variable. In wave mechanics the dynamical variable is a wave- function. This wavefunction depends on position and on time and it is a complex number – ... where we have introduced the Hamiltonian operator H.

www.pa.ucla.eduQuantum mechanics may be formulated in two stages. 1. The principles of quantum mechanics, such as the definitions of states, observables, are general and do not make assumptions on whether the number of particles in the system is conserved during time evolution. 2. The specific dynamics of the quantum system, described by the Hamiltonian, may or
