"How everything works," David McAuley

A photo: GettyYour child ever dismantled toys, wanting to see what they have inside? Or maybe he prefers to build whole cities from the designer? Then he will definitely like the colorful encyclopedias of the popularizer of science David McAuley "How everything is arranged" and "How it is built." The first will help the young researcher to understand the laws of physics and understand exactly how different objects work. But this is not at all like a school textbook: the material in the book is very simple. Here is how the author talks about the frictional force: "The frictional force occurs whenever one surface touches another (and thus their motion relative to each other), and also if the object moves in a liquid or gas. Friction is due to the fact that the surfaces interact with each other on contact. And the more they are pressed together, the stronger the interaction. Forces interacting between molecules of surfaces attract them to each other. The closer the molecule, the stronger the friction. "Photo: illustration from the book But this is just the beginning. Acquainted with the new physical law, you will find out in which devices it is used. For example, in the chapter on frictional force you can read about car tires, parachute, car brake system, drilling rig and clutch. Accessible explanations, humor, bright pictures and schemes make complex stuff so simple that even a ten-year-old child can understand it. One of the chips in the book is a cross-cutting character, already loved by children from different countries. It's a mammoth who has experienced all the laws of physics in his own skin.Photo: illustration from the book
