At what speed should a car move for a red traffic light to appear green to the driver? What is heavier - a ton of wood or iron? Why does a brook babble? If you and your child like exciting puzzles and tasks, then this book is for you. It contains dozens of unusual tasks in physics, geography, astronomy and other sciences, as well as chess etudes, mathematical and optical tricks and crosswords of varying difficulty levels. Reflecting on them, you will train your logic and learn many interesting scientific facts. And if some task still turns out to be beyond your strength, then at the end of each section you will find answers with detailed comments on how to correctly build your reasoning. With the help of illustrations, the tasks become even more interesting, and many of them - for example, crosswords or chess - can be solved right in the book.
