The stars have a spirit rhino.

Challenge the beauty of the planet's trajectory.

After reading the title, many people are still confused.

To put it more simply, two points follow a fixed circular orbit and keep moving, so the line between the two points will keep moving. However, because of the different orbital radii and different operating speeds between the two stars, the distance between them is not necessarily fixed, and there will be a closest distance and the longest distance between the two planets, but the line always exists.

When the time has passed, and the two planets have circled a certain number of times, the line will draw a complex and different trajectory map.

The challenge for the trainees is simple.

The guests randomly selected the two planets in the galaxy given by the system, and then the participating team members only looked at the rotation trajectories of the two stars to determine what kind of trajectory the line would draw in the early, middle and late stages of the two planets.

The match is also based on the accuracy of the match, and when both sides have the same correct rate, the winner takes less time.

The difficulty lies in the fact that when the guests determine the two planets, there are only the rotational trajectories of the two planets on the computer simulation screen, and the virtual line does not exist, which requires the spatial imagination of the students; and the nebula and meteorite are also added to the screen, which directly leads to the fact that the trajectory of the two planets will be covered in many cases, which further increases the difficulty.

Not to mention the fact that the different trajectory diagrams of the three stages are perfectly judged.

Of course, these orbit charts do not need to be drawn by the contestants themselves, and there are 160 orbital charts that contain all the three phases of any two planets connected in the question, as well as some confusing orbit charts.

Many of these orbital charts are often similar, and some of them are directly mirror images of left, right, and up and down.

How can you say the difficulty......

......

"Hey, I didn't expect the second question to be much easier than the first one, why don't you kick this question?" Basically, the scientists in the audience had not finished introducing the difficulty, and Wang Yufei spoke.

For Wang Yufei, this topic is really simple.

In fact, when it comes to space, imagination has always been his forte.

On his first day at the provincial middle school, he sat in the classroom and looked at the physics book, and the three-dimensional circuit diagram of all the buildings in the entire school appeared in his mind.

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

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

You don't need to think about it, you can simulate the answer in your mind at a glance.

Of course, it's really hard to empathize with this ability.

For example, this sentence was exchanged for an extremely melancholy white eye.

Lu Yuxin said sullenly: "The person you need to fight is below, why don't you even let me go?" I began to regret agreeing to participate in this show. Why don't you hurry up and promote the brain-computer chip according to the plan and then let's get out, I don't want to know what the third question is. ”

Wang Yufei was also puzzled and said, "What?

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

......

Offstage, the show has been carried out to the point where one contestant on each side has been selected to start accepting the challenge.

Each person initially has five minutes to observe the orbits and velocities of the eighteen planets in the galaxy.

If you can calculate the various parameters smoothly, you will be more efficient in the next challenges.

And this step probably made Wang Yufei feel the program team's estimation 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 it is good to directly let the guests choose a good planet and start the competition directly.

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

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

Lu Yuxin nodded sincerely: "Yes!"

"Oh well. I'll go later. ”

"Hmm!"

......

The two players on the stage had already used up five minutes of pre-observation time.

Enter the topic selection of guests.

The solution time given by the program team is one hour.

According to Wang Yufei's judgment, if it is under normal circumstances, it should be able to reach a conclusion in five minutes.

However, when two competitors pressed the button almost at the same time, the shortest time was 15 minutes and 37 seconds.

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

Obviously, they are quite satisfied with this challenge time.

The players selected by the international team this time are the British player Paul who taught Wang Yufei to be humble.

Wang Yufei could even see that the reason why he was a second slower than the Huaxia team was because this guy looked up in the direction he was sitting before slapping the button.

Well, the master has made a move, and this glance determines the outcome of the battle.

Soon it was another verification session, and when it was determined that the answers of the two players were correct, and the Huaxia team pulled back a point, no one was disappointed, and the alarm sounded again.

If the first alarm sounded was an accident, this time it was anticipation.

For the audience, when they accept that the kicking guests belong to non-human beings, what they want to see now is whether this guy can continue to create miracles.

"Then 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 kicking the gym, but directly let Wang Yufei decide for himself.

"Five minutes!"

"Five minutes?"

"Right for five minutes!"

"Do you need another five minutes to see the planets?"

"No, I don't. It's easier, just let the two contestants choose a planet each, and I'll get started. ”

"Good!"

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

Each of the plates has nine different planet numbers.

The two of them each choose a planet, which will become the next challenge for Wang Yufei.

"Let me make sure again, does it really only take three minutes? You must know that there are another 160 planetary trajectories here, and it is probably not enough for me to look at these 160 trajectories up close for five minutes. ”

When the two contestants who had just finished the challenge chose the topic for Wang Yufei, Jiang Jianming reconfirmed with a smile.

"It's okay, when they chose the pictures just now, there were already a lot of pictures on the big screen, and I probably already knew it. ”

Wang Yufei said.

Of course, killing everyone couldn't imagine that Wang Yufei was still very modest.

According to his thoughts, such a simple question would be enough for about one minute.

It's not always too shocking.
