Hello! It is the start of the school year for many. This time the newsletter is concentrating on geometry.

2. Harold Jacobs Geometry: a reviewI had been wanting to get a copy of this book for years, and I kept looking if I could find a used copy for $10$20 somewhere. But after several years, I decide that just wasn't going to happen, and got me a used copy for what they generally sell: between $30$50. That price alone tells you about the popularity of this book. Of course Jacobs' Geometry isn't popular without a reason. I will strive to explain here why people like it so well. First of all, it has to do with Jacobs' writing style: he clearly loves geometry (and mathematics) himself, and writes about it in an interesting and humorous way. Every new lesson starts out with some clever notion of that particular geometric topic taken from real life, often from cartoons. So... it is not written as a "facts book" alone, but as a book that you enjoy reading through, even if you weren't studying geometry. And secondly, the exercises. It is here that Jacobs really exceeds. A tremendous portion of the exercises are tied in with reallife examples and illustrations, which makes them more interesting than regular textbook exercises. They often cite old math books or math books from other cultures, or come from art, architecture, nature, illusions, sports, chemistry, geography, astronomy, etc. Continue reading my review of Harold Jacobs Geometry 3. Why is high school geometry difficult?
