I have very little doubt that any university freshman who has had Professor Lewin for any physics courses will never forget the experience. Why? The book's cover says it all. In the first 69% or so of the book, Professor Lewin discusses basic physics - touching upon various topics such as Newton's Laws, gravity, optics, sound, electricity, etc. The physics is very elementary such that a science buff is not likely to learn anything new here. But the highlight of these discussions is the joy of discovery that they impart to the reader. The author's enthusiasm and amazement for his subject matter is truly exceptional. Throughout, he describes various demonstrations that he's done in class in order to illustrate some particular points - and relishes his students' reactions. He goes out of his way to ensure that the students have fun and will remember what they've seen. Also located in the earlier part of the book is a bit of autobiographical information: mainly Professors Lewin's childhood in his native Holland during World War II and how difficult and horribly tragic life was at that time.
In the next few chapters, comprising about 27% of the book, Professor Lewin discusses his professional life and achievements in x-ray astronomy. This was a treat for me because, once again, his enthusiasm does not cease to grace every page and the details that he provides were mostly new to me. Finally, in the last chapter, he discusses mainly his love for modern art.
Written in clear, very friendly and lively prose, this book should be of particular interest as much to high school students and university freshmen for the clear information that it contains as to the seasoned science buff for the way it is expressed and for the information on the discovery and evolution of x-ray astronomy. If all science classes were taught like Professor Lewin teaches his physics classes, there would probably be more scientists in the world.
