Xueba's Sea of ​​Stars

Chapter 228 Solar Sail

"Have you participated in the IPhO with him?" Leonard was a little surprised after hearing Aiden's words, "But it's normal, those who can reach the finals in the IPhO will basically go down the road of physics to participate in this competition." The competition is no surprise."

"Mr. Leonard, what I'm discussing with you is whether it's strange for him to appear here? What I want to express is that this Chinese man should start his show on the podium instead of competing with us on the same stage! "

"Are you being psychologically shadowed by him? Even if he was the champion of your year, it doesn't mean that he will win this time. Don't worry, buddy will help you win this time." Leonard said and clapped his hands He patted Aiden on the shoulder, as if leaving it to me.

But Aiden gave him a blank stare, "Do you understand what I'm saying? Do you think I'm panicking like this because he won the IPhO championship? After that competition, I knew this guy named Wu Bin The guy is definitely a devil-level monster, so I paid special attention to him later, and guess what kind of feat he accomplished when he was a freshman."

"Hey~ Are you still following his news?" Leonard subconsciously took a step back, looking at Aiden with strange eyes.

Aiden decisively gave Leonard a middle finger, and then said: "This guy published "Science Advances" in his freshman year, or the cover article, can you believe it?"

"Science!?" Leonard was startled, "This is too monstrous."

After admiring Leonard, he looked at Wu Bin, whom Aiden had pointed out to him just now, and felt a powerful aura suddenly erupt from him.

"So." Aiden patted Leonard on the shoulder, "Do you understand my feeling that the game has not started yet, but I feel that I have already lost?"

"F***" Leonard's mentality also collapsed.

……

Wu Bin, who didn't know that before the start of the game, he had ruined the mentality of the team, led his teammates into the computer room, and began to download the topics of the game.

【Solar Sail Journey to Mars】

【Ion Thruster】

"Sure enough, it's all questions that need to go to heaven..." Zheng Wenhan swallowed after reading the questions.

Because this competition is sponsored by the United States Astronomical Administration, they have long thought that there will be a high probability that there will be a topic that will go to the sky, but in general, their preparations are still on the rocket side, so now they are still confused when looking at the two topics compared.

"A new type of weapon..." Bo Jiasheng couldn't help swearing.

Then after a series of negative emotions such as ignorance, discomfort, and helplessness passed, both Jiasheng and Zheng Wenhan couldn't help turning their heads to look at Wu Bin, their eyes were so helpless.

"Why, let me choose?" Wu Bin asked, pointing at himself.

"Big brother, please." The two men bent down towards Wu Bin at the same time and made a gesture of invitation.

So Wu Bin stroked his chin and read the two questions completely.

Solar sails and ion propulsion, these two things can be regarded as the product of sci-fi into reality, among which ion propulsion is used to solve the problem that traditional chemical rockets must carry a large amount of fuel, resulting in most of the launch weight of a rocket being fuel. The problem of inefficiency.

The solar sail is trying to find a new way for humans to navigate in the universe.

After struggling for a long time, Wu Bin felt that the question of solar sails was more interesting, so he turned around and asked his two teammates: "I want to choose solar sails, how about you?"

"The solar sail is good." Bo Jiasheng immediately gave a thumbs up.

"Well, I think it's good too." Zheng Wenhan immediately agreed.

"That's it." Wu Bin waved his hand and decided.

Thousands of years ago, human beings knew how to sail on the endless ocean with inflated sails, but how could human beings who know how to use force give up a force that is ubiquitous in the solar system.

Yes, that is light.

Light, a wave-particle duality visible to the naked eye, is what many people think of as the electromagnetic spectrum that illuminates the world.

To be honest, when he read the papers related to solar sails for the first time, Wu Bin couldn't help but admire the brains of these senior scientific researchers who think about the stars and the sea all day long.

Solar sails, also known as light sails, are space navigation technologies that rely on the expansion of a large-area thin-film structure and use the extremely weak light pressure generated by sunlight photons on the surface of the light sail to achieve propulsion.

Although the thrust generated by each photon "hitting" the solar sail is extremely small, in the absence of friction in space, this force can gradually accumulate to push the spacecraft forward.

The topic of this competition is Solar Sail Journey to Mars. Participants are required to build a physical model of the interstellar flight of a light-driven solar sail spacecraft, and optimize the route to obtain the maximum passenger capacity and shorten the voyage time.

Of course, the idea of ​​taking passengers on a solar sail to Mars for a day trip is only a theory.

Although Japan successfully launched the first solar sail spacecraft "Icarus" in 2010 and successfully arrived near Venus six months later, a large number of astronomers and physicists have begun to conduct a lot of research on this spacecraft , but carrying passengers is still in the stage of living a dream.

Looking at Bo Jiasheng who was a little confused, Wu Bin patted him on the shoulder and said: "First build the power model of the solar sail and the model of the solar sail in orbit. I will help you with subsequent optimization."

"Okay, I'll try my best." Bo Jiasheng nodded vigorously.

……

48 hours later, Wu Bin sent the paper he had checked to the official email. Then he looked at the two exhausted teammates next to him and said with a smile: "Want to celebrate? Western food? Bar? You all do it this time. Very good."

"No... I can't open my sleepy eyes." Bo Jiasheng waved his hand weakly.

Because he didn't want to be a character who only hugged his thighs, he insisted on the principle of never asking Wu Bin if he could solve it by himself, so he burned a lot of brain cells.

But in the end, when he got Wu Bin's affirmative nod, he still felt quite fulfilled.

Zheng Wenhan was similar, too sleepy after a day of fighting on the computer and didn't want to say anything.

So Wu Bin could only shrug his shoulders and said, "All right, then go back to the hotel."

"Hey, hello."

Just when the three of them walked out of the computer room, an American brother who was about 1.9 meters tall suddenly stopped in front of Wu Bin.

Wu Bin was taken aback for a moment, then looked at his face and thought it looked familiar again, but he couldn't remember where he had seen it before, so he asked, "Hi, what's the matter?"

The big American brother immediately extended his hand and introduced himself: "My name is Aiden. I participated in the same IPhO as you. I believe it must be God's arrangement to meet you again in my country. Would you like to have a drink together?" A glass? Of course, I treat you."
