Liu Qian performed a wonderful poker magic show on the Spring Festival Gala in 2024, and the whole process was extremely tortuous, and the audience seemed to be in a gripping suspense drama.
Liu Qian invited the audience and the audience in front of the TV to participate in the whole interaction. I'm sure a lot of people are responding and engaged, and success and failure are bound to weave different stories. All in all, it was a very interesting experience.
Liu Qian's magic trick looked quite complicated, so after his successful completion, the audience erupted in warm applause. However, in retrospect, it may not be that difficult. The layman looks at the bustle, and the insider looks at the doorway. What's going on with this magic? Soon, a student from Fudan University's School of Mathematics revealed its secret, and it was presented in handwritten form. Let's take a look.
He first had to prepare four cards, and it should be noted that Liu Qian's cards were indeed chosen at random, and the audience was also chosen at will. Let's say the four cards are A, B, C, and D.
The four cards are then ripped apart from the middle and the four halves are placed on top of the original half-cards, resulting in eight cards, arranged as abcdabcd.
Rearrange the deck with the number of letters contained in your own name. Here's how to do it: if your name consists of two letters, take out two cards in turn and place them at the bottom of the deck, so that the deck becomes cdabcdab; If your name consists of three letters, take three cards in turn and place them at the bottom of the deck, and the same will become dabcdabc. And so on.
Something interesting is about to happen. Pick up the three cards above and place them in the middle of the place. This way, the cards in your hand will show a dabcabcd, or bccdaadb, and so on. In any case, the top and bottom cards are the same. This step is crucial.
Then, take the top one off, hide it, and place it anywhere, under a pillow or under a quilt.
This is followed by a variety of different shuffles, such as putting the top card in the middle if you're a Southerner; And if you're a northerner, put the top two in the middle. But no matter how you shuffle the cards, the bottom one will never change.
The cards you have in your hand and the hidden ones remain the same.
The next step is amazing, and we call it "Throwing a Card According to the Password".
If you discard one of the seven cards and become abbccd, and then move the cards from top to bottom according to the password "Witness the miracle time", you will get the result of D. Let's say the seven cards are AABCCD, and if it's a boy, discard one of the cards and discard it.
After the girl loses two cards, the cards in her hand become BBCCD, and after the cyclic shift, it becomes D The moment to witness the miracle "happened."
The miracle is about to unfold, and this is the final step of the witness.
To start, you can start by saying "Good luck to me" and then take a card from the top of the pile and put it on the table; Then say "Dissipate your worries" and throw away the topmost card. This is repeated until only one card is left in your hand.
You'll be surprised to learn that this ** is the D.
As long as everyone plays it correctly, this card is the one you hid earlier! How remarkable! Simple and complex at the same time! Complex yet simple!
What is this principle? Many people can do it, even the so-called demystification, but they don't know what it is, they don't know anything about it.
I heard that students from Tsinghua University also came to share how to solve the problem, although I can't understand it, but it should be fine. These top students are really powerful, and they are beyond people's reach.
I understand that this falls under the category of algorithms, but I prefer to call it a kind of magic. Even though we knew it was nothing more than a dull mathematical algorithm, we were still fascinated by the festive and mysterious atmosphere created by the magician, and we were deeply moved by the charm on display. This is the embodiment of professional sophistication. What we know is that success depends not only on training so much that practice makes perfect, but also on emotional intelligence, the courage to explore, and continuous effort.
