xx Preface


               three times. When you have gotten a score that makes you happy, you can check to
               see where your knowledge is strong and where it can use some bolstering.
                   It is not necessary to have a mathematical or scientific background to use this
               do-it-yourself course. Junior-high-school algebra, geometry, and physical science
               will suffice. I’ve tried to gradually introduce standard symbols and notations so it will
               be evident what they mean as you go. By the time you get near the end of this book,
               assuming you’ve followed it all along, you should be familiar with most of the symbols
               used in schematic diagrams.
                   I recommend that you complete one chapter a week. An hour daily ought to be
               more than enough time for this. That way, in less than nine months, you’ll complete
               the course. You can then use this book, with its comprehensive index, as a perma-
               nent reference.
                   Suggestions for future editions are welcome.
