I recently read this book by Jordan Ellenberg, and I wanted to briefly discuss it. My first impressions:

- Is that really where “not” belongs in the title? (Answer: yes.)
- This is nothing like The Grasshopper King.
- The footnotes are fun.

Jordan introduces the book with a college student asking why math is so important. This book is an answer of sorts: It provides a bunch of simple, yet profound morsels of mathematical thinking. Actually, most of Jordan’s examples reveal how to properly think about the sort of math you might encounter in a newspaper (e.g., statistical significance that balding signifies future prostate cancer). I wonder if this book could form the basis of a “Math for the Humanities” type of class. Such a class might have more to offer the non-technical college student than calculus would. Overall, I highly recommend this book to everyone (including my mathematically disoriented wife).
