A memory palace is a method of memorization as well as a book.

Also known as Matteo Ricci's Palace of Memory, this book is about a rational way of remembering that has existed since a long time ago.

There are different opinions about the origin of this way of remembering, but in fact, one is that it comes from ancient Rome, which is a secret that is not passed down by a few scholars. It is precisely because of this method that university scholars can obtain wisdom far beyond ordinary people.

The other is that it comes from ancient Greece and is said to have originated from the Greek poet Simonetes. One day, Simonites left the Grand Ballroom after reciting a hymn, when the ballroom suddenly collapsed, killing all the guests and making their bodies blurry and unrecognizable. Simonites, who survived, calmly analyzed the position of the guests in the hall afterwards and identified the bodies one by one. His abilities shocked many people, and he was finally pressured to tell the secret of his memory.

There is also a theory that originated in the European Middle Ages and is a secret art that exists among some mysterious groups. Because printing was not widespread at that time, many books needed to be memorized by human brains, so this secret technique was born. Because of this, those who mastered this secret art were regarded as evil sorcerers, and many were tied to the stake and burned to death.

And the person who carried forward this way of remembering was Matteo Ricci after the Middle Ages.

Matteo Ricci was an Italian born on October 6, 1552. Born Matteo Ricci, he joined the Society of Jesus in 1571 and began his missionary career in 1577.

He went first to India and then to China, where he died in Beijing on 11 November 1610 at the age of 58 after many years of missionary life.

It is said that during his lifetime, he mastered Italian, Latin, Greek, Portuguese, Spanish, Chinese and other languages, and wrote books on theology, philosophy, mathematics, and astronomy.

And he was able to do this because he had a special way of remembering. This not only allows him to learn Chinese quickly, but also to memorize Chinese classics such as the Four Books and the Five Classics, and to quickly memorize articles, and even recite them horizontally, vertically, and upside down.

Later, he wrote a book called "The Chronicles of the Western Kingdom" to record this way of remembering.

Slowly, this way of remembering spread, and it continues to evolve, in some unknown areas, to an astonishing degree.

For example, in the World Brain Championship, some players can memorize a completely shuffled deck of cards in a dozen seconds, dictate hundreds of numbers in a few minutes, and memorize thousands of numbers in an hour.

To this extent, the way of memorization will naturally not be pure memory, let alone rote memorization, its core is logic and association. Use figurative things that are relatively easy to remember, such as images and sounds, to memorize abstract things that are relatively difficult to remember, such as numbers.

As an example, memorize an 11-digit string of mobile phone numbers in a matter of seconds: 13754718495.

There are difficulties in normal memory, but the numbers can be broken down into 137547, 18495, and then further into homophonic "Demon Mountain Flag, Samurai Flag", "One Ba is Ninety-Five", and finally become a sentence - Demon Mountain Flag, Samurai Flag Floating, the only overlord is the Ninety-Five.

In this way, the numbers become relatively logical words, and have a certain picture, which is easy to remember. After some optimization, it can even be remembered permanently. Even if you suddenly forget, as long as you recall the picture, you can remember the numbers, and you can't go wrong.

And the most orthodox memory palace method, on the basis of this method, generally requires the establishment of a personal memory place, that is, a palace.

A palace can exist in reality, such as a familiar bedroom, or it can be virtual, but it must be something that the memorizer can remember firmly.

In this way, the memorizer can place some markers in the palace to remember some of the things that are drawn.

For example, at the entrance of the memory palace, put a loaf of bread, put a book in the center of the ground of the memory palace, and put a bewitching beauty of red fruit on the iron frame in the corner of the memory palace.

In this way, every time they think of this room, they can make the memory remember the three things they had to do today—buy food, buy books, and buy ...... Well, wash the underwear.

Of course, this is only the most rudimentary demonstration of the memory palace method, and as long as you are willing to study it, the memory palace can grow from a small room to an unusually large one, so as to temporarily or permanently remember anything you want to remember.

There are even changes that others can't imagine, after all, the memory palace is completely created by the individual through imagination, and everything is possible.

But then again, memory palaces are a skill that everyone can learn, and they look cool, but they don't really work.

The main reason is that in the real world, most people are just ordinary people after all.

Therefore, when using a car, you don't need to know how the various structures of the car work, and if the car is broken, just go directly to the repair shop.

When you buy something, you don't need to know how the raw materials of this kind of thing are obtained, and you don't need to really make it yourself, you just need to spend money to buy it.

When you are sick, you don't need to know what changes have happened to your body, you don't need to perform some risky operations, and you don't need to operate on yourself, just go to the hospital.

When you are angry and ready to retaliate, you don't need to know what to do, just endure it.

Otherwise, when you are preparing to make a nuclear weapon, you will be invited to tea as long as you try to obtain some ingredients, when you are preparing to make poison, you will be invited to tea as long as you try to obtain some ingredients, and when you are preparing to make a thermal weapon, you will be invited to tea as long as you try to obtain some ingredients.

If you've had enough tea and are ready to retaliate with some simpler cold weapons, it's okay.

However, the final result is often that if you win, you go to the execution ground to eat bullet peanuts, and if you lose, you go to the underworld to drink Hu spicy Meng Po soup.

So, the skill of the memory palace, like some big truths that sound plausible, sounds very good, but in fact it is not useful.

It's really useless.

But then again, some useless things will always be in the hands of some people.

Richard, for example, is a reality master of the memory palace.

Moreover, he is also a person who is very proficient in the memory palace, and the degree of mastery is far beyond the imagination of ordinary people.

As shown in front of him, the rest of the man's palace is nothing more than a room, an attic, a building, or a town, while his palace is ...... A universe.

Universe.

That's why he can be like an encyclopedia, remembering a lot of knowledge that others can't imagine, and showing incredible abilities.

All because he has a universe in his head.
