Recently, I am reading the biography of Feynman: Then I follow the biography to go into Feynman's college days. He wrote down the Feynman-Hellmann theorem when he was senior. Then I try to find this theorem in books and intelnet. Eventually, I find what I want at http://en.wikipedia.org/wiki/Hellmann%E2%80%93Feynman_theorem.
