Quantum Mechanics - An Introduction lays the foundations for the rest of the course on quantum mechanics, advanced quantum mechanics, and field theory. Starting from black-body radiation, the photoelectric effect, and wave-particle duality, Greiner goes on to discuss the uncertainty relations, spin, and many-body systems; he includes applications to the hydrogen atom and the Stern-Gerlach and Einstein-de Haas experiments. The mathematics of representation theory, S matrices, perturbation theory, eigenvalue problems, and hypergeometric differential equations are presented in detail, with 88 fully and carefully worked examples and exercises to consolidate the material. The text starts with the historical and phenomenological background and then carefully builds up the wave mechanical treatment of matter. This fourth edition includes improved explanatory remarks, a total of 88 fully worked examples, and more exercises

瓦爾特·顧萊納教授是世界知名的理論物理學傢，在原子核物理、原子物理、場論和粒子物理的廣大領域都有獨特的、首創的和係統的貢獻。他領導下的法蘭剋福哥德大學理論物理研究所是一個齣成果、齣人材、具有世界影響的研究集體，集體中由顧萊納署名的論文在600篇以上。

顧萊納還是一個教育傢，在指導眾多的研究生和年輕的研究工作者的同時長期堅持講授基礎理論課。他還是中國人民的朋友，多年來特彆支持中德閤作，曾多次來華訪問講學。
