... Now, sn is Hermitian, so it must have an orthonormal basis. So clearly if | ai is one of those eigenvectors then with 100% certainty a measurement of sn will give the corresponding eigenvalue. One can show that the eigenvalues of sn are ± h̄/2. ...

In the early 20th century, it had become apparent to physicists that many phenomena, from the orbiting of electrons in atoms to the emission and absorption of light waves, did not occur on a continuous spectrum, as classical theories would predict.
