- 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. - Mass of proton is 1836 times that of

electron. - 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. - <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. - We use summation for adding up discrete

quantities. However, we use integration

while adding up continuous quantities.
