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.

Format: Hardcover
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.

Contrary of what the title might make you think, this book is not only about Pi! It covers all the various possibilities on how mathematic can apply to the everyday life.

With the help of fabulous images and illustrations, you will understand on how math has come to be a big part of our daily lives whether you realize it or not. Yes this book start with the beginning of times (the stone ages is mentioned) but you can still grasp how math has changed the lives of people on the planet for centuries. You will discover hoe the pyramids were build, how the Egyptians measure their land, how the Greeks used angles, how the stars were used to determined where the boats were on the seas, how the Romans discovered the advantages of semicircular arches, how aqueducts were built, how to make your own sundial and much more.

Whether you need to measure, weight or do some experiments, the mathematical concepts will be useful. This book will also highlights how Galileo, Newton, and many others helped to develop more mathematical concepts. You will also learn how it helps to map the world, how to measure energy, how to identify what temperature it is, how to determine the speed of light and much more! Throughout the book you will also find some fun experiments to do with your kids.

This book is so much more than just Pi and it will help you to discover the important of math in our lives. At the end of the book, you will also discover some weird and wonderful measurements like the knot, the elephant, the Scoville scale and other out-of-the-ordinary ones. For example, did you know that there is such a thing as the Big Mac index. It was invented by economists to compare the spending power of different currencies.

This was a really good book! It's got a ton of fun information about math and it's not boring, it definitely keeps the kids interested. Especially with all of the cool, colorful pictures. It's fun to have a book lying around that the kids can pick up and read about really useful information, and where all of the concepts of math that we use everyday come from.

I was really happy with the seller. It's a used book, but it is in good condition.

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.
