There are already several books on Microscopic and Macroscopic Structures. Most of them include a great deal of introductory theory, which have been omitted from the larger book because of space considerations. The net result is that this book contains real content of Microscopic and Macroscopic Structures. The purpose here is to meet the needs of teachers who present this subject to students who do not have the time or perhaps the inclination to pursue it in depth. We therefore introduce material in an elementary fashion, and present only the main facts. The point, however, is that this does present the facts in a systematic way. One can appreciate the sound of music without knowing anything of musical theory, although of course one’s appreciation is enhanced by knowing some theory. However, a book of musical theory, even if it is illustrated by audible snatches of themes and a few chord progressions, is quite unlike the hearing of a real composition in its entirety. A student who has read a book on ‘Microscopic and Macroscopic Structures’ that consists almost entirely of theory and so-called principles, with but sporadic mention of the hard facts (only when they “nicely” illustrate the “principles”) has not, in actual fact, had a course in Microscopic and Macroscopic Structures.
