1. I * know * it has something to do with wave mechanics . 2. Those who used the techniques of calculus included wave mechanics ". 3. Your intuition from classical wave mechanics won't lead you too far astray here. 4. A new edition was published as " Elementary Wave Mechanics " in 1945. 5. When Bethe arrived, Sommerfeld had just received Erwin Schr�dinger's papers on wave mechanics . 6. However, this period was immediately superseded by the full three-dimensional wave mechanics of 1926. 7. Later in the same year, Schr�dinger created his wave mechanics . 8. On its appearance in 1924 it apparently had little direct connection to the wave mechanics . 9. Both depend on wave mechanics .-- T 12 : 53, 16 December 2005 ( UTC) 10. At G�ttingen, Richard Courant had taken Schr�dinger s wave mechanics formulation, both put forward in 1925!
