The stars are connected.

Challenge the beauty of the planet’s trajectory.

Many people are still confused after reading the question.

A simpler description is that two points are constantly moving following a fixed circular orbit, so the line between the two points will continue to move. However, due to different orbital radii, the two stars have different running speeds.

, the distance between them is naturally not necessarily fixed. There will be a shortest distance and a farthest distance between the two planets, but the line always exists.

When enough time passes and the two planets circle around for a certain number of times, the line will draw complex and different trajectories.

The challenge for students is simple.

The guests arbitrarily select two planets in the galaxy given by the system, and then the participating team members only look at the rotation trajectories of the two stars to determine which line will be in the early, middle and late stages of the movement of the two planets.

What kind of trajectory will each draw?

The competition also prioritizes accuracy. When both sides have the same accuracy, the one with the shorter time wins.

The difficulty is that after the guests identify the two planets, there are only the rotation trajectories of the two planets on the computer simulation screen, and the virtual line does not exist. This requires the students' spatial imagination; and there are also additional lines on the screen.

Nebulae and meteorites directly result in the movement trajectories of the two planets being obscured in many cases, which further increases the difficulty.

Not to mention having to perfectly judge the different trajectories of the three stages.

Of course, these trajectory diagrams do not need to be drawn by the contestants themselves. The site provides a total of 160 orbit diagrams including all three stages of the connection between any two planets in the question, as well as some confusing orbit diagrams.

Many of these orbital diagrams are very similar, and some of them are even direct mirror images of left, right, up and down interchanged.

How to say difficulty...

…

"Hey, I didn't expect the second question to be much easier than the first question. Why don't you try this question?" Wang Yufei said before the scientists in the audience had finished introducing the difficulty.

For Wang Yufei, this question is really simple.

In fact, spatial imagination has always been his strength.

On his first day at the middle school in the provincial capital, he sat in the classroom and read a physics book, and the three-dimensional circuit diagrams of all the buildings in the school appeared in his mind.

Even his ability to solve the twin prime conjecture is inseparable from this ability.

In fact, any problem that a computer can quickly simulate and calculate the result is really too easy for Wang Yufei.

There is no need to think about it, you can simulate the answer in your mind just by looking at it.

Of course, this ability is really difficult for people to empathize with.

For example, this sentence elicited an extremely melancholy eye roll.

Lu Yuxin said dullly: "The person you need to hit is down there, why don't you let me go? I'm starting to regret agreeing to participate in this show. Why don't you quickly promote the brain-computer chip as planned and then we leave the show, I

I no longer want to know what the third question is."

Wang Yufei was also puzzled and said: "What? Is this question difficult?"

Lu Yuxin looked at Wang Yufei sincerely and asked, "Isn't it difficult?"

…

Offstage, the show has progressed to the point where each side has selected a contestant to accept the challenge.

Everyone initially has five minutes to observe the orbits and speeds of a total of eighteen planets in the galaxy.

If you can successfully calculate various parameters, you will be more efficient in the next challenge.

And this step probably made Wang Yufei feel the program team's estimate of the difficulty of this question.

After all, according to his estimation of the difficulty of the question, this step can be completely omitted and the guests can just start the competition directly after selecting the planet.

Also, before the official competition, what does it mean when the two players keep looking at him?

This made Wang Yufei once again feel that his brain seemed really different from ordinary people: "So you really think this question is difficult."

Lu Yuxin nodded sincerely: "Yes!"

"Okay then. I'll go later."

"Um!"

…

The two players on the stage have already used up the five minutes of early observation time.

Enter the guest topic selection session.

The time given by the program team to solve the problem is one hour.

According to Wang Yufei's judgment, under normal circumstances, the conclusion should be reached within five minutes.

However, when two players pressed the button almost simultaneously, the shortest time was fifteen minutes and thirty-seven seconds.

Wang Yufei could feel that the two players were relieved at the same time.

Obviously, they are quite satisfied with this challenging time.

The player selected by the international team this time is the British player Paul who had previously taught Wang Yufei that he should be more humble.

Wang Yufei could even see that the reason why he was one second slower than the members of the Chinese team was because this guy looked up and looked in the direction where he was sitting before pressing the button.

Well, when masters compete with each other, this glance determines the outcome.

Soon it was the verification stage again. When it was confirmed that the answers of both players were correct and the Chinese team regained one point, the alarm sounded again without disappointing anyone.

If the first time the siren sounded was unexpected, this time it was expected.

For the audience, once they have accepted that the kicking guest is a non-human existence, what they want to see now is naturally whether this guy can continue to create miracles.

"So, classmate Wang Yufei, how long do you think it will take you to complete this challenge?" When Wang Yufei stood next to Jiang Jianming for the second time, the host did not continue to repeat the rules of the game, but directly let Wang Yufei decide for himself.

"Five minutes!"

"five minutes?"

"Right five minutes!"

"Do I need to give you another five minutes to look at the movement of the planets?"

"No. To make it easier, why not let the two contestants just choose a planet each, and then I will start."

"good!"

In everyone's silence, the staff soon gave two tablets to the two players standing next to them.

Each of the tablets has nine different planet numbers.

If the two of them each choose a planet, it will become Wang Yufei's next challenge.

"Let me confirm again, does it really only take three minutes? You must know that there are another 160 planetary trajectory maps. For me, it takes five minutes to look at all 160 trajectory maps at close range.

Probably not enough."

When the two contestants who had just completed the challenge chose a topic for Wang Yufei, Jiang Jianming confirmed again with a dumbfounded voice.

"It's okay. When they were selecting pictures just now, there were already many pictures on the big screen. I probably already knew them by heart."

Wang Yufei said.

Of course, no one would have thought that Wang Yufei was still very humble.

If he goes by his idea, about one minute would be enough for such a simple question.
Chapter completed!
