Yakov Perelman, the legendary master of "smart entertainment", knows how to turn mathematics and logic into an exciting game. Entertaining Puzzles, Challenges, and Magic Tricks is a book that will help you look at any "miracles" differently: instead of mysticism and guesswork, you'll see clear lines of thought, precise rules, and the pleasure of understanding how everything works. The tricks here are not for the sake of effect, but for the sake of discovery.: how to remember the impossible and find hidden patterns where others see randomness. Perelman gently but persistently teaches the main skill of reasoning: step by step, without leaps, with a test of intuition. In the book:- Why is "mind reading" not a miracle, but a trick?- How to repeat magic tricks with numbers, coins, dominoes and matches?- How to train memory without cramming?- How do you notice hidden clues in questions?- How to solve puzzles without guessing, but understanding?- How to quickly decompose the task into steps and come up with your own riddles?This book is for schoolchildren, parents, and anyone who loves intellectual games and wants to improve their thinking. Perelman does something rare: he simultaneously entertains and teaches you to think accurately. Read, try, and show your friends — and you'll see how logic becomes your most effective focus.
