"You've been to IPhO with him?" Leonard was a little surprised after listening to Aiden's words, "But it's normal, those who can fight in the finals on IPhO will basically go down the road of physics, and it's not surprising to participate in this competition." ”

"Mr. Leonard, what I'm discussing with you is the question of whether it's strange that he's here? What I want to express is that this Chinese should stand on the podium and start his sho, instead of competing with us! ”

"Are you being beaten out of the psychological shadow by him? Even if he is the champion of your year, it doesn't mean that he will win this time, don't worry, buddy will help you win it back this time. Leonard patted Aiden on the shoulder and looked like he would leave it to me.

Aiden, on the other hand, gave him a roll of the eyes, "Do you understand what I'm saying?" Do you think I'm panicking like this just because he won the IPhO championship? After that competition, I knew that this guy named Wu Bin was definitely a monster at the level of a demon king, so I paid special attention to him later, and guess what kind of feat he accomplished when he was a freshman. ”

"Oh~ Are you still tracking his news?" Leonard subconsciously took a small step back, looking at Aiden's eyes strangely.

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

“science！？” Leonard was shocked, "This is too wicked." ”

After marveling, Leonard looked at Wu Bin, who Aiden had pointed out to him just now, and felt that a powerful aura suddenly erupted from his body.

"So." Aiden patted Leonard on the shoulder, "Do you understand how I feel like I'm losing before the game starts?" ”

"F***" Leonard's mentality also collapsed at this time.

……

Wu Bin, who didn't know that he had broken the mentality of a team before the game started, walked into the computer room with his teammates and began to download the questions of this competition.

【Solar Sail to Mars】

【Ion thruster】

"Sure enough, it's all about going to heaven......" Zheng Wenhan swallowed after reading the title.

Because this competition is sponsored by the United States Astronomical Bureau, they have long thought that there is a high probability that there will be a problem that will go to the sky, but in general, they are still relying on the rocket side in terms of preparation, so now they are still confused when they look at the two questions.

"What's the new weapon......" Bao Jiasheng couldn't help but burst into foul language.

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

"What, let me choose?" Wu Bin pointed to himself and asked.

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

So Wu Bin rubbed his chin and read both questions in their entirety.

Solar sails and ion thrusters, both of which are the products of science fiction into reality, are used to solve the problem that traditional chemical rockets must carry a large amount of fuel, resulting in the inefficiency of the vast majority of the launch weight of a rocket is fuel.

The solar sail, on the other hand, is an attempt to find a new way in which humans can sail through the universe.

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

"The sun sail is good." Bao Jiasheng immediately gave a thumbs up.

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

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

Thousands of years ago, mankind knew how to sail on the endless ocean with a puffed sail, but how could such a man who knew how to borrow power give up a force that was omnipresent in the solar system.

That's right, that's light.

Light, which many people have the impression of illuminating the world, is a wave-particle duality that is visible to the naked eye.

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 scientific research predecessors who think about the stars and the sea all day long.

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

Although the thrust generated by each photon "hitting" the solar sail is very small, in the absence of friction in space, this force gradually accumulates to propel the spacecraft forward.

The contest, titled Solar Sailing to Mars, asked participants to build a physical model of the interstellar flight of a light-driven solar sail spacecraft to optimize the route to maximize passenger capacity and shorten the voyage time.

Of course, the fact that the sun sails to Mars for a day trip is only theoretical.

Although a large number of astronomers and physicists have begun to study the vehicle since Japan successfully launched its first solar sailing spacecraft "Icarus" in 2010 and successfully reached the vicinity of Venus six months later, it is still in the stage of living in a dream.

Looking at the somewhat confused Bo Jiasheng, Wu Bin patted him on the shoulder and said: "First establish the power model of the solar sail and the model of the solar sail in orbit, and I will help you with the optimization later." ”

"Okay, I'll try." Bao Jiasheng nodded vigorously.

……

Forty-eight hours later, Wu Bin sent the paper he had checked to the official mailbox, then looked at the two exhausted teammates next to him and said with a smile: "Do you want to celebrate?" Western food? Bar? You've all done a great job this time. ”

"No...... Sleepy eyes can't be opened. Bao Jiasheng waved his hand weakly.

Because he didn't want to be a character who would only hug his thighs, he had been insisting on the principle of never asking Wu Bin if he could solve it by himself in the past two days, so he burned a considerable amount of brain cells.

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

Zheng Wenhan is similar, he doesn't want to say anything if he is sleepy after a day of fighting on the computer.

So Wu Bin had no choice but to shrug his shoulders and say, "Okay, then go back to the hotel." ”

"Hey, hello."

Just as the three of them walked out of the computer room, an American big brother with a height of about 1.9 meters suddenly stopped in front of Wu Bin.

Wu Bin was stunned for a moment, then looked at his face and felt a little familiar, but he couldn't remember where he had seen it, so he asked, "Hello, is there something wrong?" ”

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