Fantastic Book! I *LOVED* the book called "Why Pi?".
I've never done a video review of a book before, but this book inspired me to make it my first!
This book is terrific for anyone who loves math, or who wants to love math!
It is vibrantly colorful, and full of great short stories (mostly just a paragraph or two to illustrate each point) that clearly explain how basic understanding of math has helped people throughout history to figure out how the world works, and how to understand, measure and interact with the world we live in.
Five stars for this book!

I picked this up through Scholastic ordering at my childs school. He's an advanced first grader, and loves this book. It's written in bite-sized paragraphs (perfect for short attention spans!) full of interesting information. It's made to be able to be read for a page or two and picked up again later if needed...or make it one long sitting and re-read as needed. Bright colors and interesting pictures help fill out information ranging from ancient measurement techniques, discoveries by Copernicus, Galileo and Newton (to mention a few), measuring temperature, energy, electricity, light, pressure and sound. Lot's of good stuff here, and I'm only touching the surface. It's a good place to get your kids feet wet in why math and science are interesting. It's been good for the whole family to browse.

This book introduces many mathematical concepts while giving you the history of these concepts. The ideas are clearly presented in an entertaining way that makes it hard to stop reading. I found it to be educational and engaging. My wife and I are reading this at the same time as our kids, the book keeps moving around our house as each person takes off with it when it is left unattended.

Math can be fun? For centuries mathematicians have defined our world with measurements, weights, heights, sizes, and random facts. A whole culture of people have tried to turn numbers/math into a religion.

Why Pi? celebrates the history of our world from astronomy in the ancient world, measurements and the origin of pi, latitude, longitude, waves, and random facts. For the geeks at heart, this is their High School Musical Guidebook, their Coles notes to life. My daughter loves this book, and her sister ate it up!

Well compiled, illustrated and annotated. Highly enjoyable yet educational at the same time.

Math rooms, teachers, and libraries should not be without this tome.

Thanks.
Numerically speaking.

Excellent homeschool resource - Math shouldn't be dry and boring - and it won't be with this book :-) Interesting introductions to a variety of math topics. Also highly recommend G is for Google: A Math Alphabet Book.

When I checked out the humorous introduction, I though, I have to get this for Angie. So, I bought this for my 10 year-old daughter and she really loves it. She actually says this! Amazingly, it has led to her asking for other books that are similar in availability and reading level.

This book was fantastic. My husband, who is a statistics guy, and I both poured over it when we got it. It is brilliant in the way that it flows from one subject to the next. It has so much content in such a manageable, but fun delivery. The kids enjoy going through it and finding out new factoids every time. Great book that should be in every house with children.

Our six year old son absolutely adores reading this book (and others by the same author) at bedtime. Every page is a fascinating combination of mathematical facts, historical context and interesting problems. The fact that my wife and I look forward to reading it as much as our son does is remarkable. We're buying everything written by Johnny Ball.
