General Relativity for Babies Board book

My 3 year old is picking up on the concepts the more we read this. He will pick this book off the book shelf for me to read to him; I never have to force him to read it with me. The pictures are basic but that helps emphasize the concepts

Written by an expert, General Relativity for Babies is a colorfully simple introduction to Einstein's most famous theory. Babies (and grownups!) will learn all about black holes, gravitational waves, and more. With a tongue-in-cheek approach that adults will love, this installment of the Baby University board book series is the perfect way to introduce basic concepts to even the youngest scientists. After all, it's never too early to become a quantum physicist! Baby University: It only takes a small spark to ignite a child's mind.
