Review written April 17, 2021, from a library book
What a fun book! It covers simple geometry topics such as symmetry, tessellations, polygons, angles, parallel and perpendicular lines, and relates them all to pie.
With every single concept covered, we get the question, “How does this relate to pie?” Here’s an example:
How Does Radius Relate to Pie?
When it comes to serving only one piece of pie, the first cut is typically from the center point of the pie to the crust. This cut represents the radius of the pie. That cut, like the radius, could be made in any direction to the circumference, as long as it is from the center point of the pie to the crust.
Here’s another such question with an especially good answer:
How Do Geometric Formulas Relate to Pie?
Suppose someone asks you how to make a pie and you just read them a recipe out of this book. Will you really understand pie-making as well as if you’d actually made the pie yourself? In the same way, rather than just memorizing geometric formulas, it’s important to work with and understand the mathematical ideas behind the formulas. In this book, the thinking behind mathematical concepts is explained first, before we give you formulas. In the same way, we hope you actually try to make the pies you read about in this book!
The book is illustrated with many, many photos of luscious-looking pies, and yes, a variety of recipes are included. I’m a little ashamed to say I did not try any of them out. But I may have drooled over the photos.
