Connor's Hogwarts

Listen carefully, this class is quite boring, no dozing is allowed

Divination can be used to trace the past, explore the present and deduce the future.

Divided according to skill proficiency, looking back at the past is an introduction, exploring the present is proficiency, and deducing the future is a master.

It's a pity that the vast majority of wizards cannot deduce the future, which is almost the pinnacle of wizards' learning of divination.

Even Professor Victor, who specializes in arithmetic and divination, dare not and will not call himself a master of divination. The future is unpredictable and it is not so easy to deduce.

Except for divination, all divinations about the future cannot be guaranteed to be accurate.

Below, we will explain in detail the divination techniques under various circumstances.

The first is divination of the past.

Facts that happened in the past can no longer be changed, so divination can be used for more accurate backtracking.

Of course, the longer the interval, the lower the accuracy of backtracking, but in general, divination used to be the simplest of divination, which can be regarded as the foundation and entry.

Then there is divination now.

The second before now is the past and the next second is the future. "Divining the present" generally refers to divining where someone or something is at this time, what they are doing, whether they are alive or dead. Things that happened.

For example, the Weasley family has a prophet's clock, which is handed down from their ancestors, which can reflect the status of family members in real time, and the Marauder's Map, which is also one of the applications of divination for "divination of the present". One, all of these must be done by wizards who are proficient in divination.

Finally, divination of the future.

Divining the future is very difficult, and as the number of future divination increases and the accuracy of divination increases, the difficulty of divination will increase exponentially.

In terms of time intervals, wizards can generally predict the future accurately... usually no more than 10 seconds.

Take a chestnut.

In a Quidditch match, it is known that the Quaffle will enter the circle and score in the next second. At this time, it is necessary to predict whether the goalkeeper Wood will use the left whip or the right whip first when defending... This is divination of the future. Divining the future in one second is, after all, simple, and can be calculated with just a few fingers.

But as the future you want to predict becomes longer, for example, if you want to use divination to predict the result of the game at the beginning of the game, it will be very, very difficult, almost impossible.

Otherwise, why not play Quidditch? Why not just let the two masters of prophecy go to the middle of the field to announce the results?

If a wizard forcibly divines the long-term future, his eyes will be blackened and he will not be able to see anything.

Every minute and every second every choice made by every person will affect the direction of the future. There are too many "variables" that affect the future.

The above is the grading of divination difficulty under various circumstances. Next, students will turn to the second page of the textbook. Let’s talk about the divination principles of divination...

When wizards perform divination, they must form a magic circle first. It is a complex compound magic pattern. There are many genres. Most people cannot draw a magic circle by themselves, so they usually use magic tools that describe the magic circle, such as magic circles. mirror, crystal ball and tarot cards.

After preparing the props, what the fortune teller has to do is to "enter instructions" and "analyze answers." How to correctly input instructions and analyze answers is what is taught in the fortune telling class. I will not go into details here. We only need to know One point will suffice, that is, the results of divination are not calculated by wizards.

This is the main reason why Connor would say that divination is somewhat like a computer.

Because divination is like a "program" that belongs to the world itself. As long as you input "variables" into it, it will instantly output a "result" to you through a series of "calculations".

Speaking of which, everyone should also understand why Professor Victor is excited.

After understanding the basic operating principles of computers, Victor also discovered the similarities between divination and computers.

The input variable information is processed to obtain the result. This is the basic process that Professor Victor saw on the computer. It seems to be the same as divination.

The more and more detailed input variables are, the faster and more accurate the output results will be. When the "variables" are too large to be measured, the future is naturally impossible to predict.

Divination does not involve information processing. Divination is just a tool for input and output. So what is actually being calculated?

This is quite controversial in the wizarding world, but Professor Victor feels that she has discovered the truth. Perhaps she can rely on this subject to become famous throughout the ages...

Okay, after talking about the basic principles of divination, we move to the last part of this lesson, the practical application and practice of divination. Finally, we will also talk about the most cutting-edge research results and research directions of divination...

Although it is difficult for wizards to accurately predict the future, it does not mean that wizards cannot "divinate the future".

In fact, wizards have long understood that divination is difficult to predict the future. They know that it is difficult to accurately predict the future, but this does not mean that they have given up using this "program" that belongs to the world. On the contrary, they think of taking advantage of it. The best way to "predict the future" is to start with divination.

What does it mean? It is actually very simple. Since the accurate results are difficult to predict, then we can blur this positioning and make the divination results accurate with a "high probability". Therefore, arithmetic divination came into being.

Let's take another chestnut.

Captain Wood wanted to win the next Quidditch match, so he asked classmate A, who was proficient in arithmetic and divination, to help him. Then classmate A, who was proficient in arithmetic and divination, took out a set of tarot cards, did a fortune telling for Wood, and got A bunch of decks that can be interpreted in any way other people think.

Then classmate A mysteriously told Wood that you have a high winning rate in this game, but there may be a bloody disaster. You must remember not to be careless, dodge as much as possible, and the secret must not be leaked. If you want rat tail juice, so on...

After a flick, Wood left happily, and finally the result of the game came out, and Gryffindor won, but Quaffle didn't talk about Wood, and dealt with him face to face, causing him to vomit three liters of blood and leave the field midway. Everything was exactly in line with the divination result.

Tico, from this point of view, is this arithmetic divination reliable?

From the professional point of view of wizards, this is of course reliable. Wizards no longer predict the future accurately, but calculate the "probability" of events, and then after thousands of years of testing this set of "natural laws" In summary, Tarot cards become one of the practical applications of arithmetic divination.

Although the results of divination may be unclear and ambiguous, it is indeed a proven and practical magic. The most important thing is that divination is very objective and will not change with the subjective will of the caster. of...

It means that when you want to divination the outcome of an event, no matter who you switch to divination, the conclusion you get will be the same, the only difference lies in the level of detail of the divination.

Unless...you have the blood of a prophet.

The next thing I want to talk about is the cutting-edge research on divination in the wizarding world.

What I said before was just the general wizard's understanding of divination, but there are always some unique people in this world, such as the blood of the prophet, they can predict the accurate future unreasonably.

Wizards have never given up on the exploration of prophecy. They all want to understand the difference between ordinary wizards and prophet blood.

The explanation generally accepted by wizarding scholars today is "cost theory".

The price to be paid for divination by ordinary wizards is different from that of prophetic bloodlines. Ordinary wizards only need to pay magic power for divination, while the price for divination by prophetic bloodlines is vitality.

Wizarding scholars believe that divination is more of a "deal" than ordinary magic, a deal with the world itself.

You are responsible for providing information and paying the price, and the world will return some information to you according to the "rules". If the price you pay is large enough, the information you get will be precious enough, such as finding a world with all the possibilities in the future. Nodes where lines intersect.

However, under normal circumstances, ordinary wizards simply cannot find this window to trade life with the world.

, this is the news revealed by the blood of the prophets, so many wizards believe that this so-called "spiritual vision" is actually a window to pay the price to the world, and only the blood of the prophets can see it.

The previous wizards were unable to prove this conjecture, but Professor Victor felt that this conjecture might be confirmed here, as long as she could complete the project sent by the students and make a computer for wizards
