Unformatted text preview: , , , , , , , . ... In quantum mechanics ``observables'' are often quantised, they cannot take on all possible values: how to represent such quantities? We have already seen that energy and momentum are represented by operators, (8.1) and (8.2) Let me look at the Hamiltonian, the energy operator. We know that its normalisable solutions (eigenvalues) are discrete. (8.3) The numbers are called the eigenvalues, and the functions the eigenfunctions of the operator . Our postulate says that the only possible outcomes of any experiment where we measure energy are the values !...
