 ====The Doctor 12/18====
 What are people doing for the 4th question on the practice final?  Is it actually really easy or am I'm thinking about this wrong?
+===Anaximenes - 00:40 - 12/19/09===
+Near as I can tell, it should just be <math>\psi_a (x_1)\psi_b (x_2) - \psi_b (x_1)\psi_a (x_2)</math>.  Is that what you were thinking?  Or do you think the problem wants us to multiply in the spin wavefunction?  E.g., <math>\psi_a (x_1)\psi_b (x_2)[\chi_+ (x_1) \chi_- (x_2) - \chi_- (x_1) \chi_+ (x_2)]</math>?  (I'm not especially certain that expression actually means anything.)
+====Esquire 12/19 (Age of Final)====
+What did you guys think about the final? I thought it wasn't terrible, thought I didn't get a few things.
+===Anaximenes - 15:30 - 12/19/09===
+I thought it was good.  All of it was reasonable (not incredibly easy or difficult), but it covered a wide range of topics.  What did everyone put for #6?  Those open-ended questions always take me the longest.  I described how the graph shows the Zeeman effect is dominant at high <math>\beta</math> but Fine Structure is dominant at low <math>\beta</math>; that of the 8 energy eigenvalues, 4 had simultaneous eigenstates of j, <math>j_z</math>, <math>m_l</math>, and <math>m_s</math>; and that the two middle eigenvalues have <math>\displaystyle \lim_{\beta \rightarrow \infty} \lambda = -3\gamma</math> (i.e., they become degenerate).
+=== Blackbox 12/19 ===
+I'm just wondering whether these kinds of questions and answers or opinions about the exams are also counted in the total.
