  1. H Ψ = E Ψ, is the Schrödinger’s wave
    equation. The left hand side is the
    Hamiltonian, i.e., the total energy (kinetic
    energy + potential energy).
    And the right hand side is E, the total
    energy. It shows the conservation of energy
    principle.
  2. Mass of proton is 1836 times that of
    electron.
  3. Ψ doesn’t have any physical significance
    as it’s a complex number, so we take its
    complex conjugate and multiply with it to get
    probability density. Max Born proposed this,
    also called Born Interpretation of quantum
    mechanics.
  4. <ΨI is a bra vector. And IΨ> is a ket
    vector. They make up together to give
    <ΨIΨ> , which complets to form a bra-ket.
  5. We use summation for adding up discrete
    quantities. However, we use integration
    while adding up continuous quantities.
