本书以量子力学的建立过程为线，介绍了什么是量子力学以及量子力学在原子世界中起着什么样的作用等。

本书包括伽利略的“时间绝对论”、爱因斯坦的“时空相对论”、秦元勋的时空质“三一理论”等。

This book was written as an introductory text for a one semester course and， as such， it is far from a comprehensive reference work. Its lack of completeness is now more apparent than ever since， like most branches of mathematics， knot theory has expanded enormously during the last fifteen years. The book could certainly be rewritten by including more material and also by introducing topics in a more elegant and up-to-date style. Accomplishing these objectives would be extremely worthwhile. However， a significant revision of the original work along these lines， as opposed to writing a new book， would probably be a mistake. As inspired by its senior author， the late Ralph H. Fox， this book achieves qualities of effectiveness， brevity， elementary character， and unity. These characteristics would be jeopardized， if not lost， in a major revision. As a result， the book is being republished unchanged， except for minor corrections. The most important of these occurs in Chapter III， where the old sections 2 and 3 have been interchanged and somewhat modified. The original proof of the theorem that a group is free if and only if it is isomorphic to F[] for some alphabet contained an error， which has been corrected using the fact that equivalent reduced words are equal.本书为英文版。

It is almost a trivial observation that many collective endeavours require the accomplishment of numerous complicated tasks， and that the different individuals that perform them may lose sight of the overall design. Like other creative endeavours， the scientific quest is particularly prone to such a state of affairs， for not only does the difficulty of the tasks absorb the mind but the beauty of what is learnt in performing them engages the soul. Like a diver， who may be so charmed by the nearby coral so as to forget that its beauty is but a minute reflection of the majestic beauty of the ocean， a spectroscopist may be so taken by the beautiful symmetries that the molecules exhibit so as to loose sight of the wonderful structure of quantum mechanics that informs them.　本书为英文版。
