PS #5 due up front; PS #4 returned. Erratum: The final answer to Q3R.1 should be 3 . 9 × 10 17 m 40 light-years; the rest is correct. Quiz tomorrow. Anything from the 1094 session is fair game, so please go through the answer key. 1094 Session 3 is returned up front (key is online). Common error: forgetting that | z | 2 = z * z and not z 2 . Be careful not to mix up eigenvalues and the coefficients of eigenvectors. An eigenvector does not have to be an energy eigenvector. Consider a magnetic field in the + x direction. In that case, only | + x i and | - x i are energy eigenvectors; the others (e.g., | + z i and | - y i ) are eigenvectors for spin-projection on the z -axis and y -axis but do not have definite energy. Probability: square wave function ψ ( x ) first, then add area. Time dependence is important! (We’ll review it today.) Quick warm-ups: | 1 + 2 i | 2 ? = | 1
