Non-Euclidean Geometry for Babies

I usually hate all the toys that come in their regular color or pink, with the assumption being that girls can only play with pink toys, but since this is a math book and the description says it's perfect for babies who prefer pink (as opposed to saying it's perfect for girls) it's fine. I'm not sure my baby prefers pink over blue, but he loves Angelina Ballerina and Bratz and a bunch of other girly cartoons, so he got the pink version.Anyway, so far my 2.5yo baby boy has been pointing at the circles and points and lines and saying "circle", "point", "line", or one of the various colors. I don't think he's really 'getting' any of the geometry yet (Euclidean or non), but he's having fun. And that was the point of the book, right? It has some fun word play "Angle one is a cute little angle" and "Those four angles look all right to me" that is lost on little kids but makes me smile every single time I read it to my son.My only problem with the book is that it's a roughly 8.5" by 8.5" paperback, which makes it pretty vulnerable near babies/toddlers. It really would be better if it were a boardbook. Then I'd be able to leave it out for the kids to look at themselves whenever they feel like it, and I wouldn't have to keep reminding my son to be gentle with it while I'm reading it to him.

I own several of the Math for Babies series of books. While I really like the calculus one for example, this non-Euclidean geometry one is both shorter and with less interesting pictures. While it does give a baby explanation of Euclid's fifth postulate and it does show how initially parallel lines on a manifold can cross, it does not explain (in baby terms) some of the other simple ideas behind non-Euclidean geometry. So, in comparison to some of the other Math for Babies books, I feel like this one is a bit weaker. Combine that with the fact that the price is $11 and I feel the publisher is asking too much. This "book" is really more of a pamphlet and should cost about $3. You will have to decide if it is worth the price. For my wife and I (I am an engineer and she is a mathematician), we felt like this book was a bit too small and over priced for the quality of information within (which we could have taught our son for free). Three stars for this particular work.

I'll be honest, the book is called "Non-Euclidean Geometry for Babies" but I'm a 27-year-old attorney and I did not know about Non-Euclidean Geometry prior to this book. I learned a thing or two about semi-advanced mathematics. The language was simple enough for children to understand, though I'm not sure that the five-year-old child with whom I was reading this book fully grasped all the concepts. Still, it was a good way to introduce complex thought to young children, so that when they come across these concepts later in life they're not totally taken by surprise.

This is a fantastic book. I bought this for my 10 month old. At that age she could only sit still while I read it to her for about half the book but now that she's a a little over 1 year, she is happy turning the pages and letting me read it to her pretty much all the way through.The concepts laid out in the book are fantastic. I thoroughly enjoy that the author starts with basic geometric ideas and then builds on why these may or may not be the whole story. This is a great way to teach young children. As a result, I thoroughly recommend this book to anyone looking for an entertaining and highly educational way to introduce their child to higher level's of spatial reasoning!

I'm going to paste the same review I gave for "The Pythagorean Theorem for Babies" since I think both books are equally great:The famous mathematician John von Neumann said, "In mathematics you don't understand things; you just get used to them." So, the earlier you start getting used to them, the better. This is a great book to start baby getting used to the concepts of mathematics. The trick is to make it appeal to both parents and kids. And this book does just that.

So if your kid is preverbal, this isn't going to have much of an obvious impact; but it's simple and cute and doesn't try to do more than present the concepts in a fundamental way. It succeeds, and my kid thinks it's funny. Is he getting anything out of it? Maybe so, maybe no; but while he doesn't love it as much as Are You My Mother or the Little Pooky oeuvre, he likes it a lot. And so we're both pleased. What more do you want?

All of the teachers got together to purchase a variety of books for another teacher's expected baby. This book was the most well received in the bunch!As a math teacher, I am very critical of baby books that are about math. This one is amusing for adults with a bit of know-how and has brightly colored graphics to go along with the story of the "other" kinds of geometries.I will now ALWAYS purchase this book for little babies!

These books are a hoot.They are also a clear & accurate explanation of their concepts.Math loving parents will be thrilled.

The book arrived in good time. Clear illustrations, and good explanations. I find it hard to explain the concepts in any other way.

Excellent layered approach to a technical topic.

fun book.Good for everyone
