Ravenclaw College's most famous motto is, "Superior wisdom is the greatest treasure of mankind." ”

Whether it is the Eagle Ring, the students, or even the style and environment of the college, they all show their thirst for knowledge, as well as their unrestrained and imaginative wisdom and thoughts.

However, in addition to this, Elena happened to hear another sentence - mathematics is the most brilliant jewel in the crown of human wisdom.

Throughout the long history of human civilization, at least half of the philosophical thinking and questions are wonderfully related to some mathematical logic. In fact, hundreds of years ago, people called mathematics natural philosophy.

"We're not trying to embarrass the students, we're just passing on the knowledge and letting the glow of philosophical reflection shine back in the Ravenclaw common room......"

Elena looked at Xenophilius Lovegood, who had straight eyes, shook her head, and said with a chuckle.

Just now, she updated the question bank of the Bronze Eagle Ring a little, telling a few interesting logical stories.

After these several communications with the Bronze Eagle Ring, Elena preliminarily determined that Ravenclaw's Eagle Ring is actually more similar to a relatively primitive primary AI - with a certain ability to think, as well as information entry, judgment, and output functions.

This means that it is not up to the task of self-deducing complex mathematical tasks.

In other words, if Eagle Ring wants to propose the Barber's Paradox, or Russell's Paradox, she first needs to help Eagle Ring complete at least one of the standard answers to this question - for example, to fully explain Gödel's incompleteness theorem - so that Bronze Eagle Ring can add the "Barber's Paradox" to the question bank in the "Built-in Logic".

Of course, if she did, maybe the Ravenclaw students wouldn't want to go back to sleeping in their dorms this year.

So after a little consideration, Elena chose to start instilling from some more basic places. After all, the vast majority of young wizards at Hogwarts may not have the same mathematical foundation as the average European primary school graduate.

"I still don't understand, is there really a village in this world that can only tell lies and truths?"

Xenophilius Lovegood rubbed his forehead and tried to think hard about one of the classic example questions that Elena had just "updated" the Bronze Eagle Ring - how should the two people standing at the fork in the road and the two people in charge of guiding the way have only one chance to ask questions......

"Absolutely. Elena nodded without hesitation, "Or rather, you can understand that the people in one village drink all the truth potion every day, and the people in the other village drink all the truth potion every day." ”

"Lie potion? what is that, how did I not know there was such a thing......"

Xenophilius raised an eyebrow in confusion.

"Oh, if only you understood it as a potion as the opposite of the Truth Elixir. ”

Elena waved her hand, casually fooling the potion she had improvised to the occasion.

Anyway, there are many wonders in the world, and it is always much more difficult to prove that something does not exist than to prove that something exists.

As Albert Einstein famously said, "Science can only prove that it exists, it can't prove that it doesn't exist, and if it can't prove that something doesn't exist, you can't say that it doesn't exist." ”

And when all this is happening in the wizarding world, the Lovegoods and "Singing Against the Tune" are undoubtedly the most apt case - whether it is the "scimitar-horned snorer", "harassing fly", or "moon frog", "giant with octopus tentacles", the same is true.

Click.

As Xenoflius Lovegood continued to search for information about the "Elixir of Lies" in his mind, he heard a soft sound of the door closing in front of him, and a word wafting through the crack in the door.

"Luna, come, I'll show you around the Ravenclaw lounge. ”

"Hmm? wait......"

Xenophilius Lovegood looked up a little dazedly and looked left and right.

At some point, Elena had dragged her precious little moon through the open eagle ring door into the Ravenclaw common room, and ...... And closed the door again?!

Thankfully, if Xenophilius Lovegood is not mistaken, the Eagle Ring at Ravenclaw House, although it has some headaches from time to time, doesn't change too many times in the same day.

At least for this short period of time, it should still be the same problem.

Without thinking much about it, Xenophilius Lovegoods quickly knocked on the bronze eagle ring, he was not worried that his daughter was alone in the room with a little wizard who did not know the details, even if the other party was just a little loli of one meter two.

And just as he remembered, he saw the bronze eagle ring open his mouth and say again in a gentle voice:

"There are a certain number of three-headed dogs and phoenixes locked up in a room at the same time, count ...... from above"

"The answer is thirteen phoenixes and eleven three-headed dogs. ”

Before the Bronze Eagle Ring could finish reading the question, Xenophilius Lovegood frowned and quickly interrupted.

Even though he didn't know how he came up with this answer, it didn't prevent him from remembering Elena's correct answer.

In fact, this is what Ravenclaw has always done - as long as a smart person solves the puzzle, everyone can successfully enter the common room.

However, to his surprise, this time, the door to the common room did not open as he remembered.

“...... Sixty-four heads from above, and one hundred and eighty-two feet from below. How many three-headed dogs and how many phoenixes are there in the room?"

“？？？”

The expression on Xenophilius Lovegood's face froze again, although at first glance, it seemed to be the same question as before, but when you think about it, there seems to be something wrong with this situation at the moment.

Immediately after, as if in response to the confusion in Xenophilius's heart.

I saw that the bronze eagle ring that had accompanied the middle-aged wizard for seven years on campus opened his mouth again and continued to add in that gentle, musical voice.

"I'm sorry, I answered incorrectly. ”

“？？？”

Xenophilius Lovegood's eyes, which had been a little bulging outward, widened a little, and his gaze subconsciously crossed over the row of light blue velvet sleeping bags hanging from the wall of the corridor below, and a very bad guess suddenly appeared in his mind - if the question was indeed regarded as "the same" by the Eagle Ring, then ......

Sure enough, the next moment, I heard the bronze eagle ring once again gush out of its mouth with the same tenderness as ever, but it was like a demon whispering to repeat.

"There are a certain number of three-headed dogs and phoenixes locked up in one room at the same time, counting one hundred and twenty-five heads from above......"
