Homework Help: Why classical physics work in quantum mechanics

  1. Oct 8, 2012 #1
    im finally writing my conclusion for my Extended Essay.

    The extended essay (EE) is a mandatory core component of the IB Diploma Programme. It is a research paper of up to 4,000 words giving students an opportunity to conduct independent research or investigation on a topic that interests them.

    but i am a it stuck.
    my research question is "What is the difference between classical and quantum physics and why does classical physics not work on quantum level particles respect to Schrödinger’s equation?”

    i have shown what values we get if we calculate the total energy of an electron using classical physics formulas and the total energy of an electron using Schrödinger’s equation.

    but why doesnt it work.
    what are the consequences of using classical physics on quantum level particles

    A classical trouble with classical physics is the stability of atoms. Related problematic phenomena are discrete atomic spectra and the photoelectric effect.
