“Pavel Sigismundovich Ehrenfest introduced me to Landau at a conference on theoretical physics in Berlin at the very end of 1929. Landau said to me regretfully: 'Just as all the pretty girls are all spoken for and married, so are all the best problems already solved ... I doubt if I shall find anything worthwhile among those that remain.' But he did find something. In January 1930, while staying with Pauli in Zurich, he discovered what he called the last of the great problems - the analysis in quantum terms of the movement of electrons in a constant magnetic field. He solved this problem in the spring of that year while in Cambridge with Rutherford. So it was that Landau's diamagnetism and Pauli's paramagnetism came upon the scene at the same moment in the history of physics ...” -  Quantum Generation: Highlights and Tragedies of the Golden Age of Physics, Margarita Ryutova-Kemoklidze (Маргарита Рютова-Кемоклидзе)

“正如所有的漂亮妹子不是已经和人家拍拖就是已经被人家娶走,所有的好问题也都被解决了... 我都怀疑自己还能不能在剩下的东西里面发现任何有价值的课题。” - 朗道,1929,发现恒磁场电子的量子运动问题的前夜
