Homework Help: Significance of commutators in Quantum mechanics

  1. Sep 11, 2011 #1
    1. The problem statement, all variables and given/known data
    why we do use commutation?

    what is physical difference between commutators and Poisson Brackets?

    2. Relevant equations

    3. The attempt at a solution

    Poisson brackets are used in the Hamiltonian formalism of classical mechanics. When you quantise a theory, these become the commutators you know and love from quantum theory.
