Dr. Tetsuya Fujita, a.k.a. Ted, a.k.a. Mr Tornado was a meteorologist who spent most of his career at the University of Chicago. When I was in graduate school, I was down the hall from him and a friend (Eric) was one of his students. One day, Eric told me a Ted story.
Dr. Fujita held up a book on fluid dynamics (one of the central subjects for studying meteorology) and said to Eric "See this book? I only know chapter one." (maybe it was 'use'. Been a few years.) At the time, I thought it was more than a little exaggerated. And it probably did have a fair amount of exaggeration (Ted wasn't above such things). But, as I've continued my career and studies, I see more and more truth and wisdom in that comment.
I don't know about that particular book. But as I re-open math and science books I read years or decades ago, I'm continuing to find meaning and importance very early in the text. Not because I didn't learn enough of the early chapters to do well in class and tests, or to be able to apply the knowledge in later years at work. Rather, because as I've worked more on the subject, or learned more outside it, I see that there are more and more connections to 'chapter one' material. In that case, there's a lot of merit to looking back at chapter one and seeing how much deeper a knowledge I (you too, probably) can get from the later viewing.
