Magic versus fortune telling

What is mathematical magic is introduced as follows:

Mathematical magic refers to the magic made by using mathematical principles.

brief introduction

Because the effect is very good, people often ignore the mathematical principle. Mathematical magic began in 1600, and was used by so-called fortune tellers to calculate people's age. This is the origin of the first mathematical magic. With the changes of the times, mathematical magic is also evolving, from simple addition, subtraction, multiplication and division to complex equation calculation, applied to magic, even the area is included.

Dominique Suday is a famous magician. He opened the magic of mathematics and brought people little-known places in mathematics. He is known as the most famous mathematical magician in modern times and the author of 84 magical mathematical tricks. Related mathematical magic, Flash Minder reader and Cards Minder reader are all included in this book, all of which are explained in detail.

Mathematical magic can be said to be a combination of disciplines, which brings mathematical knowledge into magic and applies magic to mathematics.

The following is a poker magic that applies mathematical principles:

1. Take 2 1 cards, let your opponent randomly draw 9 cards, choose one you like, and remember the number of cards you like.

Put that card back, divide it into three cards, and then take out one at random and ask the other party if the card he drew is in this one. If not, put it back on the table and ask the other two people if they have seen his card.

3. Put the opponents who have drawn cards in the middle and put them away.

4. Don't shuffle the cards. After you put them away, continue to distribute the cards in three parts. Ask him which card he drew in the same way as the first time, and then put the card he drew before in the middle.

5. Repeat this for three times, remember not to shuffle the cards in the middle.

6. Then count from the top until the eleventh card. That card was drawn by the opponent before. You can also put the cards on the back to make your opponent feel more magical and difficult to see the flaws.

This magic applies mathematical principles, that is, the ternary number principle. The fourth step is to put the cards drawn by the opponent in the middle card, so that all three cards contain the opponent's cards, which is the core idea of ternary system. In the next step, the three cards are divided into different groups, and each group is arranged in a certain order, so that the opponent's cards are in a specific position. This magic trick needs to be repeated many times to add mystery, but the key principle is the ternary number principle.
