Unformatted text preview: component in the wave functon. We do expect or with 50 % propability, which leads to the right average. Actually simple mathematics shows that the result for the expectation value was just that, . We can generalise this result to stating that if (8.28) where are the eigenfunctions of an (Hermitean) operator , (8.29) then (8.30) and the probability that the outcome of a measurement of at time is is . Here we use orthogonality and completeness of the eigenfunctions of Hermitean operators....
