Why are Arabic numerals actually Indian? Can you measure length with elbows and palms? What numbers are called round? How to learn to count with strings? In the new book of the children's encyclopedia series, Chevostik and Uncle Kuzya will... embark on an unusual journey and find out why it is impossible to build a ship, paint a picture, and even… bake a pie without knowledge of mathematics. They will learn what a geometric figure is, what units of length and weight people used in ancient times, and they will also see how mathematics helps doctors perform complex surgeries. Who is Chevostik? Chevostik is a cute character from a well-known audio project. Today, kids know him from the encyclopedias. The series continues to release books that explain the structure of the world to children. Children perceive information much better when it is told to them by a fairy-tale character. That is why boys and girls love such encyclopedias. Chevostik and Uncle Kuzya take amazing journeys into the world of sciences: physics, chemistry, astronomy, anatomy, geology, and others. He tells children about great geographical discoveries, the conquest of space, and magical chemical transformations. Who is this book for? For curious children aged 6 and up. For all Chevostik fans.
